Legislation: B Substitution of a statutory provision - Effect of - Held: Substitution of a provision is a combination of repeal and fresh enactment. c Appellants challenged thP. vires of the Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, 2006 as null and void before the Appellate Tribunal for Electricity and had prayed for quashing of the said Regulations. The Tribunal dismissed the appeals holding that its jurisdiction was restricted by0 the limits imposed by the parent Statute, i.e., the Electricity Act, 2003. The Tribunal held that the appropriate course of action for the appellants was to proceed by way of judicial review under the Constitution of India. Hence the present appeals. E The questions for consideration before the Court were: (i) Whether the Appella~e Tribunal constituted under the 2003 Act has jurisdiction u/s. 111 of the Act, to examine the validity of the 2006 Regulations (ii) Whether F capping of trading margins could be done by the Central Electricity Regulatory Commission (CERC) by making a Regulation in that regard u/s. 178 of 2003 Act and (iii) Whether Parliament has conferred power of judicial review on the Appellate Tribunal for Electricity u/s. 121 of G the 2003 Act.

Dismissing the appeals, the Court HELD: 1.1. A regulation u/s. 178 is made under the authority of delegated legislation and consequently its H PTC INDIA LTD. v. CENTRAL ELECTRICITY 611 REGULATORY COMM. THR. SECRY. validity can be tested only in judicial review proceedings A before the courts and not by way of appeal before the Appellate Tribunal for Electricity under Section 111 of Electricity Act, 2003. [Para 59] [684-H; 685-A] 1.2. The decision-making and regulation-making 8functions are both assigned to CERC. Law comes into existence not only through legislation but also by regulation and litigation. Laws from all three sources are binding. A statutory instrument, such as a rule or regulation, emanates from the exercise of delegated legislative power which is a part of administrative process C resembling enactment of law by the legislature whereas a quasi-judicial order comes from adjudication which is also part of administrative process resembling a judicial decision by a court of law. [Para 37] [664-H; 655-A-C] D Shri Sitaram Sugar Co. Ltd. v. Union of India and Ors. (1990) 3 sec 223, referred to.

1.3. Price fixation exercise is actually legislative in character, unless by the terms of a particular statute it is E made quasi-judicial as in the case of Tariff fixation u/s. 62 made appealable u/s. 111 of the 2003 Act, though Section 61 is an enabling provision for the framing of regulations by CERC. If one takes "Tariff'' as a subject-matter, one finds that under Part VII of the 2003 Act actual determination/ fixation of tariff is done by the appropriate F Commission u/s. 62, whereas Section 61 is the enabling provision for framing of regulations containing generic propositions in accordance with which the appropriate Commission has to fix the tariff. This basic scheme equally applies to subject-matter "trading margin" in a G different statlltory context. [Para 38] [665-D-F] 1.4. Section 79 delineates the functions of CERC broadly into two categories - mandatory functions and advisory functions. Tariff regulation, licensing (Including H 612 SUPREME COURT REPORTS [2010) 3 S.C.R.

A inter-State trading licensing), adjudication upon disputes involving generating companies or transmission licensees fall under the head "mandatory functions" whereas advising Central Government on formulation of National Electricity Policy and tariff policy would fall B under the head "advisory_ functions". In this sense, CERC is the decision-making authority. Such decision-making u/s. 79 (1) is not dependant upon making of regulations u/s. 178 by CERC. Therefore, functions of CERC enumerated in Section 79 are separate and distinct from c function of CERC u/s. 178. The former is administrative/ adjudicatory function whereas the latter is legislative. [Para 39) [666-H; 667-A-C) Mis. Narinder Chand Hem Raj and Ors. v. Lt. Governor, Administrator, Union Territory, Himachal Pradesh and Ors. D (1971) 2 SCC 747; Indian Express Newspapers (Bombay) Pvt. Ltd. and Ors. v. Union of India and Ors. (1985) 1 SCC 641, relied on.

1.5. On reading Sections 76(1) and 79(1) one finds E that CERC is empowered to take measures/steps in discharge of the functions enumerated in Section 79(1) like to regulate the tariff of generating companies, to regulate the inter-State transmission of electricity, to determine tariff for inter-State transmission of electricity, F to issue licenses, to adjudicate upon disputes, to levy fees, to specify the Grid Code, to fix the trading margin in inter-State trading of electricity, if considered necessary, etc .. These measures, which CERC is empowered to take, have got to be in conformity with the G regulations u/s. 178, wherever such regulations are applicable. Measures u/s. 79(1 ), therefore, laave got to be in conformity with the regulations u/s. 178. To regulate is an exercise which is different from making of the regulations. However, making of a regulation u/s. 178 is not a pre-condition to the Central Commission taking any H PTC INDIA LTD. v. CENTRAL ELECTRICITY 613 REGULATORY COMM. THR. SECRY. steps/measures u/s. 79(1 ). If there is a regulation, then the A measure u/s. 79(1) has to be in conformity with such regulation u/s. 178. The dichotomy between the power to make a regulation u/s. 178 on one hand and the various enumerated areas in Section 79(1) in which CERC is mandated to take such measures as it deems to fulfil the B objects of 2003 Act. [Para 40] [667-F-H; 668-A-C]

1.6. In the hierarchy of regulatory powers and functions under the 2003 Act, Section 178, which deals with making of regulations by the Central Commission, under the authority of subordinate legislation, is wider C than Section 79(1) of the 2003 Act, which enumerates the regulatory functions of the CERC, in specified areas, to be discharged by orders (decisions). [Para 59] [684-E-F] 1.7. In the instant case, instead of fixing a trading D margin (including capping) on a case to case basis, CERC thought it fit to make a regulation which has a general application to the entire trading activity which has been recognized, for the first time, under 2003 Act. Making of a regulation u/s. 178 became necessary E because a regulation made u/s. 178 has the effect of interfering and overriding the existing contractual relationship between the regulated entities. A regulation u/s. 178 is in the nature of a subordinate legislation. Such subordinate legislation can even override the existing F contracts including Power Purchase Agreements which have got to be aligned with the regulations u/s. 178 and which could not have been done across the board by an order of the CERC u/s. 79(1)(j). [Para 40] [669-8-E] National Hydro-electric Power Corporation Ltd. v. CIT G 2010 (1) SCALE 5; Mis Southern Technologies Ltd. v. Joint Commissioner of Income Tax, Coimbatore 2010 (1) SCALE 329, relied on. 1.8. Applying the test of "general application", a H 614 SUPREME COURT REPORTS [2010] 3 S.C.R.

A regulation stands on a higher pedestal vis-ii-vis an Order {decision) of CERC in the sense that an order has to be in conformity with the regulations. However, that would not mean that a regulation is a pre-condition to the order {decision). Therefore, it cannot be said that under the B 2003 Act, power to make regulations u/s. 178 has to be correlated to the functions ascribed to each authority under the 2003 Act and that CERC can enact regulations only on topics enumerated in s. 178(2). Apart from Section 178(1) which deals with "generality" even u/s. c 178{2){ze), CERC could enact a regulation on any topic which may not fall in the enumerated list provided such power falls within the scope of the 2003 Act. Trading is an activity recognized under the 2003 Act. While deciding the nature of an order {decision) vis-a-vis a regulation under the Act, one needs to apply the test of general0 application.

(1985) 1 SCC 641; City Board, Mussoorie v. State Electricity Board and Ors. AIR (58) 1971 Allahabad 21·9, referred to. G 1.9. On the making of the impugned Regulations 2006, even the existing Power Purchase Agreements {"PPA") had to be modified and aligned with the said Regulations. The impugned Regulation makes an inroad into even the existing contracts. This itself indicates the H width of the power conferred on CERC u/s. 178 of the . PTC INDIA LTD. v. CENTRAL ELECTRICITY 615 REGULATORY COMM. THR. SECRY. 2003 Act. All contracts coming into existence after making A of the impugned Regulations 2006 have also to factor in the capping of the trading margin. This itself indicates that the impugned Regulations are in the nature of subordinate legislation. Such regulatory intervention into the existing contracts across-the-board could have been B done only by making Regulations u/s. 178 and not by passing an Order u/s. 79(1)(j) of the 2003 Act. Therefore, it becomes clear that the word "order' in Section 111 of the 2003 Act cannot include the impugned Regulations 2006 made u/s. 178 of the 2003 Act. [Para 43] [672-H; 673- c A-DJ

1.10. If a dispute arises in adjudication on interpretation of a regulation made u/s. 178, an appeal would certainly lie before the Appellate Tribunal under Section 111, however, no appeal to the Appellate Tribunal D shall lie on the validity of a regulation made under Section 178. [Para 59J [685-E] 2.1. On the question of "generality versus enumeration" principle, the enumerated factors/topics in E a provision do not mean that the authority cannot take any other matter into consideration which may be relevant. The words in the enumerated provision are not a fetter; they are not words of limitation, but they are words for general guidance. [Para 49] [677-C-F] F Hindustan Zinc Ltd. etc. v. Aridhra Pradesh State Electricity Board and Ors. (1991) 3 SCC 299; Shri Sitaram Sugar Co. Ltd. v. Union of India and Ors. (1990) 3 SCC 223, relied on. G 2.2. Applying the principle of "generality versus enumeration", it would be open to the Central Commission to make a regulation on any residuary item u/s. 178(1) r/w Section 178(2)(ze). The CERC was empowered to cap the trading margin under the authority H 616 SUPREME COURT REPORTS [2010] 3 S.C.R. A of delegated legislation u/s. 178 vide the impugned Notification dated 23.1.2006. [Para 59] (685-F-G]

3.1. Section 121 of the 2003 Act does not confer power of judicial review on the Appellate Tribunal. The words "orders", "instructions" or "directions" in Section 8 121 do not confer power of judicial review in the Appellate Tribunal for Electricity. In the 2003 Act, the power of judicial review of the validity of the Regulations made u/ s. 178 is not conferred on the Appellate Tribunal for C Electricity. [Para 59] (685-B-D] Mis Raman and Raman Ltd. v. State of Madras and Ors. AIR 1959 SC 694, relied on. 3.2. It is not correct to say thats. 121 has not yet been o brought into force. At the outset, the material brought on record indicates that Section 121 of the original Electricity Act, 2003, was never brought into force because some MPs expressed the concern that the power, under that Section, conferred upon the Chairperson of the Appellate E Tribunal, could lead to excessive centralization of power and interference with the day-to-day activities of the Commission by the Chairperson of the Tribunal.

Therefore, Section 121 was amended by Electricity (Amendment) Act, 2003 (No.57 of 2003) and which F amendment Act came into force from 27.1.2004. By necessary implication of the coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force, hence there is no requirement for a further Notification u/s. 1(3), particularly when Section 121 in its amended form has G come into force w.e.f. 27.1.2004. Section 121 of the original Act stood substituted by Amendment Act No. 57 '' of 2003. Substitution of a provision results in repeal of the earlier provision and its replacement by the new provision. Substitution is a combination of repeal and H fresh enactment. (Para 58] (683-D-G] PTC INDIA LTD. v. CENTRAL ELECTRICITY 617 REGULATORY COMM. THR. SECRY.

2. Leave granted. 3. In this batch of civil appeals, we are basically concerned G with the doctrine and jurisprudence of delegated legislation. QUESTIONS OF LAW: 4. The crucial points that arise for determination are: -H PTC INDIA LTD. v. CENTRAL ELECTRICITY 619 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] (i) Whether the Appellate Tribunal constituted under A the Electricity Act, 2003 ("2003 Act") has jurisdiction under Section 111 to examine the validity of Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, 2006 framed in exercise of power conferred under Section 178 of B the 2003 Act? (ii) Whether Parliament has conferred power of judicial review on the Appellate Tribunal for Electricity under Section 121 of the 2003 Act? c (iii) Whether capping of trading margins could be done by the CERC ("Central Commission'') by making a Regulation in that regard under Section 178 of the 2003 Act? DFACTS:

5. In this batch of civil appeals, appellants had challenged the vires of the Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, 2006 as null and void before the Appellate Tribunal for Electricity and had prayed for E quashing of the said Regulations. The Tribunal, however, dismissed the appeals holding that its jurisdiction was restricted by the limits imposed by the parent Statute, i.e., the Electricity Act, 2003. By the impugned judgment, the Tribunal held that the appropriate course of action for the appellants is to proceed F by way of judicial review under the Constitution. 6. In view of the importance of the question, the matter was referred by a three-Judge Bench of this Court to the Constitution Bench. While making reference to the Constitution Bench, the G question formulated was - "whether the Tribunal has jurisdiction to decide the question as to the validity of the Regulations framed by the Central Commission?" Basically, the matters involve interpretation of Sections 111 and 121 of the 2003 Act. H 620 SUPREME COURT REPORTS [2010] 3 S.C.R. I A 7.

It provides for "unbundling" of SEBs into separate utilities for generation, transmission and D distribution. It repeals the Indian Electricity Act, 1910, the Electricity (Supply) Act, 1948 and the Electricity Regulatory Commissions Act, 1998. The 2003 Act, in furtherance of the policy envisaged under the Electricity Regulatory Commissions Act, 1998 ("1998 Act"), mandated the establishment of an E independent and transparent regulatory mechanism, and has entrusted wide ranging responsibilities with the Regulatory Commissions. While the 1998 Act provided for independent regulation in the area of tariff determination; the 2003 Act has distanced the Government from all forms of regulation, namely, F licensing, tariff regulation, specifying Grid Code, facilitating competition through open access, etc.

10. Section 3 of the 2003 Act requires the Central Government, in consultation with the State Governments and G the Authority, to prepare National Electricity Policy as well as Tariff Policy for development of the power system based on optimum utilization of resources. The Central and the State Governments are also vested with rule-making powers under Sections 176 and 180 respectively, while the "Authority" has H been defined under Section 2(6) as regulation-making power PTC INDIA LTD. v. CENTRAL ELECTRICITY 653 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

under Section 177. On the other hand, the Regulatory A Commissions are vested with the power to frame policy, in the form of regulations, under various provisions of the 2003 Act. However, the Regulatory Commissions are empowered to frame policy, in the form of regulations, as guided by the general policy framed by the Central Government. They are to be guided B by the National Electricity Policy, the Tariff Policy as well as the National Electricity Plan in terms of Sections 79(4) and 86(4) after the 2003 Act (see also Section 66). In this connection, it may also be noted that the Central Government has also, in exercise of its powers under Section 3 of the 2003 Act, notified c the Tariff Policy with effect from 6.1.2006. One of the primary objectives of the Tariff Policy is to ensure availability of electricity to consumers at reasonable and competitive rates. The Tariff Policy tries to balance the interests of consumers and the need for investments while prescribing the rate of return. It 0 also tries to promote training in electricity for making the markets competitive. Under the Tariff Policy, there is a mandate given to the Regulatory Commissions, namely, to monitor the trading transactions continuously and ensure that the electricity traders do not indulge in profiteering in cases of market failure. E The Tariff Policy directs the Regulatory Commissions to fix the trading margin in a manner which would reduce the costs of electricity to the consumers and, at the same time, they should endeavour to meet the requirement for investments.

11. An "electricity trader'' is defined under Section 2(26) F to mean a person who has been given a licence to undertake trading in electricity under Section 12. Section 2(32) defines a "grid" as the high voltage backbone system of inter-connected transmission lines, sub-station and generating plants. Under Section 2(33), a "Grid Code" is defined as a code specified G by the Central Commission under Section 79(1)(h), while under Section 2(34), ·"Grid Standards" are those specified by the Central Authority under Section 73(d). Under Section 2(47), "open access" is defined to mean the non-discriminatory provision for access to the transmission lines or distribution H 654 SUPREME COURT REPORTS [2010] 3 S.C.R. A system or associated facilities given to any licensee or consumer or a person engaged in generation of electricity in accordance with the regulations specified. Section 2(62) defines the term "specified" to mean specified by regulatioris made by the Appropriate Commission or the Authority under B the 2003 Act. Under Section 2(71 ), the word "trading" is defined to mean purchase of electricity for resale thereof.

12. Under the 2003 Act, power generation has been de-licensed and captive generation is freely permitted, subject to approval as indicated in Sections 7, 8 and 9 of the Act. C However, under Section 12, a licence has been provided as a pre-condition for engaging in transmission or distribution or trading of electricity. Therefore, licensees are granted by the Appropriate Commission under Section 14 of the Act on applications made under Section 15. Section 16 provides D power to the Appropriate Commission to specify· any general or specific conditions which shall apply either to a licensee or to a class of licensees. Under Section 18, the Appropriate Commission is also vested with the power to amend the licence as well as to revoke it in certain stipulated circumstances, if E public interest so requires (see Section 19). Under Section 23, the Appropriate Commission has the power to issue directions to licensees to regulate supply, distribution, consumption or use of electricity, if the Appropriate Commission is of the opinion that it is necessary or expedient so to do for maintaining the F efficient supply and for securing the equitable distribution of electricity and promoting competition.

13. One of the most important features of the 2003 Act is the introduction of open access under Section 42 of the Act. G Under the open access regime, distribution companies and eligible consumers have the freedom to buy electricity directly from generating comp~nies or trading licensees of their choice and correspondingly the generating companies have the freedom to sell. H 14. Section 52 of tt1e 2003 Act deals with trading of PTC INDIA LTD. v. CENTRAL ELECTRICITY 655 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] electricity activity. Under Section 52(1 ), the Appropriate A Commission may specify the technical requirement, capital adequacy requirement and credit worthiness for being an electricity trader. Under Section 52(2), every trader is required to discharge its duties, in relation to supply and trading in electricity, as may be specified by the Appropriate B Commission. 15. The standards of performance of licensee(s) may be specified by the Appropriate Commission under Section 57 of the Act. c

16. The 2003 Act contains separate provisions for the performance of the dual functions by the Commission. Section 61 is the enabling provision for framing of regulations by the Central Commission; the determination of terms and conditions of tariff has been left to the domain of the Regulatory D Commissions under Section 61 of the Act whereas actual tariff determination by the Regulatory Commissions is covered by Section 62 of the Act. This aspect is very important for deciding the present case. Specifying the terms and conditions for determination of tariff is an exercise which is different and E distinct from actual tariff determination in accordance with the provisions of the Act for supply of electricity by a generating company to a distribution licensee or for transmission of electricity or for wheeling of electricity or for retail sale of e~~~ F

17. The term "tariff' is not defined in the 2003 Act. The term "tariff' includes within its ambit not only the fixation of rates but also the rules and regulations relating to it. If one reads Section 61 with Section 62 of the 2003 Act, it becomes clear that the Appropriate Commission shall determine the actual tariff in G accordance with the provisions of the Act, including the terms and conditions which may be specified by the Appropriate Commission under Section 61 of the said Act. Under the 2003 Act, if one reads Section 62 with Section 64, it becomes clear that although tariff fixation like price fixation is legislative in H 656 SUPREME COURT REPORTS [2010] 3 S.C.R. A character, the same under the Act is made appealable vide Section 111. These provisions, namely, Sections 61, 62 and 64 indicate the dual nature of functions performed by the Regulatory Commissions, viz, decision-making and specifying terms and conditions for tariff determination. B 18. Section 66 confers substantial powers on the Appropriate Commission to develop the relevant market in accordance with the principles of competition, fair participation as well as protection of consumers' interests.

C 19. Under Sections 111(1) and 111(6) respectively, the Tribunal has appellate and revisional powers. In addition, there are powers given to the Tribunal under Section 121 of the 2003 Act to issue orders, instructions or directions, as it may deem fit, to the Appropriate Commission for the performance of D statutory functions under the 2003 Act.

20. The 2003 Act contemplates three kinds of delegated legislation. Firstly, under Section 176, the Central Government is empowered to make rules to carry out the provisions of the E Act. Correspondingly, the State Governments are also given powers under Section 180 to make rules. Secondly, under Section 177, the Central Authority is also empowered to make regulations consistent with the Act and the rules to carry out the provisions of the Act. Thirdly, under Section 178, the Central Commission can make regulations consistent with the Act and F the rules to carry out the provisions of the Act. SERCs have a corresponding power under Section 181. The rules and regulations have to be placed before Parliament and the State Legislatures, as the case may be, under Section 179 and 182. The Parliament has the power to modify the rules/ regulations. G This power is not conferred upon the State Legislatures. A holistic reading of the 2003 Act leads to the conclusion that regulations can be made as long as two conditions are satisfied, namely, that they are consistent with the Act and that they are made for carrying out the provisions of the Act. H PTC INDIA LTD. v. CENTRAL ELECTRICITY 657 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] SUBMISSIONS: A On behalf of M/s Tata Power Trading Co. Ltd.:

21. On the scheme of the 2003 Act it was submitted by Shri Harish N. Salve, learned senior counsel, that, under the 8said Act the Central Commission and SERCs have to frame regulations as well as pass statutory orders. The Act uses the expression "fixed" in Sections 8, 19, 45 & 79; it uses the expression "determined" in the proviso to Section 9(2), Sections 20, 42, 47, 57, 61 and 67(2) and the word "specified" (i.e. by way of regulations) in Sections 13, 14, 15, 16, 17, 18(2), 28(4), C 34, 36, 38, 41, 42, 45, 51, 52, 53, 57, 61 and 67(2) of the 2003 Act. Under the 2003 Act, according to the learned counsel, there are a series of provisions which expressly require the Commission to frame regulations on specific aspects.

According to learned counsel, each of the said three D expressions have to be interpreted by the terms and in the context of the scheme of the 2003 Act and not by a priori notions of administrative law. For example, Section 61 posits the framing of regulations by the Commission, which will subject to the provisions of the 2003 Act, specify the terms and E conditions for the determination of tariff. It is possible that such regulations may be licensee-specific or generic. At the same time, under Section 62 read with Section 64 refers to determination of tariff in accordance with the provisions of the Act for supply of electricity by Gencoms, transmission of F electricity, wheeling and trading of electricity. Applying the Cynamide principle [1987(2)SCC720] of administrative law, such tariff Order would be characterized as delegated legislation yet under Section 111 of the 2003 Act it is made appealable to the Appellate Tribunal. According to the learned G counsel, "price fixation" is ordinarily "legislative" and not "adjudicatory" in character and yet under the 2003 Act tariff fixation is by Order and subject to appeal under Section 111. According to the learned counsel, use of different expressions in the Act implies different meanings. For example, in Section H 658 SUPREME COURT REPORTS [2010] 3 S.C.R.

A 79 the expressions used are "regulate", "determine", "adjudicate", "specify" and "fix". Where the function of the Commission under Sections 79 and 86 require framing of regulations, the Act has used the expression "specified" as defined. Therefore, according to the learned counsel, the word B "fix" in Section 79(1 )U) must mean to pass an appropriate order fixing trading margin which is further qualified by the Act saying "if considered necessary". In this connection, learned counsel further submitted that fixing trading margin is same as price fixation and as such margin must be fixed by an Order and not c by way of regulation. Hence, according to the learned counsel, regulations cannot be framed under Section 79(1)0) and under Section 86(1 )ti) of the 2003 Act.

22. On the interpretation of Sections 178(1) and 181(1) of the 2003 Act, learned counsel submitted that where rule making D powers are enumerated and there is a general delegation of power to make rules to carry out the provisions of the 2003 Act, the enumeration does not detract from the generality of the power conferred is the principle which has to be read in the context of the scheme of the 2003 Act. In this connection it was E submitted that under the Act the power to frame subordinate legislation to carry out the provisions of the Act are contained in Sections 176 and 180 on Central and State Governments; in Sections 178 and 181 where power to frame regulations is conferred on Regulatory Commissions and Section 177 where F the power to frame regulations is conferred on CEA. Hence, when the Central Government invokes the rule making power under Section 176(1), it cannot make rules to determine tariff since that can be done only by the appropriate Commission by virtue of Section 61 read with Section 178(2)(s). A perusal G of the scheme of the 2003 Act suggests that each and every provision of the Act where framing of regulations is contemplated has a counter-part in one of the clauses as set out in Section 178(2). In any event, according to the learned counsel, where the Act requires the discharge of a function by H a specific order, then a regulation cannot be framed to achieve PTC INDIA LTD. v. CENTRAL ELECTRICITY 659 REGULATORY CbMM. THR. SECRY. [S.H. KAPADIA, J.]

that very purpose merely because there is a power to frame A regulations. Therefore, according to the learned counsel, trading margin can be fixed only by an order under Section 79(1)0) and 86(1)0) and not by regulations.

23. On the powers of the Appellate Tribunal under Sections 8 111 and 121 of the 2003 Act, learned counsel urged, that, the said Tribunal was established as an expert second tier regulatory authority to review the actions of the Regulatory Commissions, including regulations framed by first tier regulatory bodies even in the absence of Section 121 of the 2003 Act. In this connection, learned counsel further submitted C that the powers envisaged under Section 121 are distinct from the appellate and revisional powers under Section 111 (3) and under Section 111 (6). A plain reading of Section 121 establishes that the Tribunal has the power to issue orders, instructions and directions to guide the Commission in the due D performance of its statutory function; that the said power to issue instructions, orders and directions would include the power to frame or modify the regulations made by the first tier regulatory authority, particularly in cases where the Tribunal is satisfied that the regulation framed is either not consistent with the provisions E of the Act or does not result in due performance of the duty or functions entrusted to the Commission under the 2003 Act. In the light of the provisions of Sections 111 and 121 of the 2003 Act, learned counsel urged, that, even in an appeal under Section 111 if the question of validity of delegated legislation F arises, the tribunal can consider the vires and ignore a Rule which is ultra-vires the rule-making power. The fact that there is no power in the tribunal to annul the regulation cannot deny the power to statutory tribunal to ignore ultra vires subordinate legislation. Lastly, there is no need to read down Section 121 G on a priori notion of classical administrative law that vires of the rules can only be challenged in the judicial review proceedings before a constitutional court.

H 660 SUPREME COURT REPORTS [2010] 3 S.C.R. A On behalf of PTC India Ltd.

24. Shri Vikas Singh, learned senior counsel, submitted that fixation of trading margins under normal business conditions is intrinsically contradictory and harmful to power market functioning. In this connection, it was submitted that8 capping of trading margin does not in any manner whatsoever control the selling price of electricity sold to Discerns. Such capping of trading margin results in relegating the electricity traders to mere commission agents. The role of electricity C traders is to play a dynamic role of bringing in new products in the market which is beneficial to the consumers as well as Gencoms. However, the entire object of having electricity traders stand defeated by impugned capping of trading margins. According to the learned counsel, traders in electricity bring depth to the electricity markets. They make value D additions and therefore interventions in trading by regulations should not be contrary to the letter and spirit of the Act [See Section 66]. According to the learned counsel, severe regulatory intervention like imposition of margin in a voluntary market should be resorted to only in cases of market failure. E According to the learned counsel, on the basis of statistical data, the trading margin is not a return guaranteed to a trader and that the actual margin which the trader is getting is lower than the prescribed cap. According to the learned counsel, none of the above facts have been appreciated by the Central F Commission in capping the margin as not to exceed 4.0 paise per kWh on the electricity traded.

25. On the question of law, learned counsel submitted that the right to appeal under Section 111 in respect of adjudicatory/ G administrative order cannot be defeated by colouring the decision as a regulation. In this connection learned counsel submitted that the rules/regulations framed by the executive under an Act are the law whereas regulations made by the statutory authority itself is not the regulation under which it functions, but the regulation making itself is its function. In the H PTC INDIA LTD. v. CENTRAL ELECTRICITY 661 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] former case, it is possible to argue that the Authority which is A the creature of the Statute cannot question the vires of the statute, in the latter case, the Authority is not the creature of the Regulation framed by itself, hence the sanctity given to the former is far greater than the sanctity to the latter. B

26. According to the learned counsel, that, the right to appeal is a substantive right and the same cannot be taken away by a device, i.e., by framing a regulation instead of simply passing an order as to denude the Appellant of its right of Appeal. In this connection, learned counsel urged that the Appellate Tribunal can hear the appeal against the regulation C being the function of the Commission and can examine the sanctity of the regulation if the same is framed beyond the power of the commission to do so. In other words, if the Commission is entitled to adjudicate upon a matter, it does not have the authority under the Act to give its decision the colour of a D regulation so as to denude the Tribunal of its authority under Section 111. According to the learned counsel, since the impugned regulation relegates the trading licensee to a commission agent the same is ultra vires Section 66 of the 2003 M. E 27. According to the learned counsel, under Section 79 the Commission is authorized only to fix the trading margin and since the impugned regulations are purportedly made under Section 79 the said regulations are beyond the powers of the F Central Commission and are, thus, ultra vires the 2003 Act. 28. Lastly, learned counsel for PTC adopted all the arguments of Shri Harish N. Salve, learned counsel for M/s. Tata Power Trading Company Ltd. G

29. Shri Narasimha, learned counsel and Others broadly adopted the above arguments advanced on behalf of Mis. Tata Power Trading Company and PTC India Ltd., hence, the same need not be reproduced. H 662 SUPREME COURT REPORTS [2010) 3 S.C.R. A On behalf of CERC 30. After taking us through the provisions of the 2003 Act, the National and the Tariff Policies, learned Solicitor General of India submitted that the 2003 Act contemplates three kinds of delegated legislation:8 (i) Under Section 176, the Central Government is empowered to make rules for carrying out the provisions of the Act. A corresponding power is given to the State Governments under Section 180. c (ii) Under Section 177, the CEA is empowered to make regulations consistent with the Act and the rules made under Section 176. (iii) Under Section 178, the Central Commission may D make regulations consistent with the Act and the rules generally to carry out the provisions of the Act. The corresponding power under Section 181 is conferred on SERCs.

E 31. The rules and the regulations have to be placed before the Parliament and the State Legislatures, as the case may be, under Sections 179 and 182 respectively. According to the learned counsel, even if the Rules have been laid before the Parliament and even if there is a resolution of the Parliament F approving them, the validity of the Rules has to be declared by the Court as ultra vires the Act and invalid. According to the learned counsel, there is no power conferred upon the Appellate Tribunal under Section 111 to declare the regulations framed by the Central Commission as null and void. According to the G learned counsel, Tribunals are creatures of the statute. They have no inherent power that exists in civil courts. Any power exercisable by the Tribunal has to be located in the statute under which it is formed. There is no authority for the proposition that under the Indian law, a statutory tribunal has H the jurisdiction to deal with the validity of subordinate legislation PTC INDIA LTD. v. CENTRAL ELECTRICITY 663 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] and pronounce it as ultra vires. Of course,· according to the A learned counsel, it is open to the Parliament to e)cpressly give to a Tribunal the power to consider the validity o~ $ubordinate . . legislation. However, such conferment has to be. express and unambiguous, which is not there in this case. B

32. According to the learned counsel, the mere fact that Section 79(1)0) uses the word "fix" and the mere fact that the other provisions .use the word "specify" does npt lead tq the conclusion that the Central Commission could not have iss\Jed the Trading Margin Regulations 2006 as contended by the appellants herein. The learned counsel further urged that the C general power to frame regulations is not limited or controlled by enumeration of topics on which regulations may be framed. In.this connection, it was submitted that a holist\c reading of the Act leads to the conclusion that regulations can be made as long as they are consistent with the Act and that they are D made for carrying out the provisions of the Act. The Act recognizes the need to regulate trading in electri~ity [See Sections 52(2), 53(1)(a), 57, 60, 178(2)(d), (o), (p) and (y)].

33. Learned counsel further submitted that for the reasons E mentioned herein there is no case made out by the Appellants to lift the veil over a fake regulation. The Central Commission had to initiate proceedings against 14 traders for non-compliance with licence conditions. Some traders were operating on high margins. Trading margin being the F component of the final price paid by the consumers required regulation to protect the consumers. Competition among traders to capture the surplus power for sale resulted in rising prices. Even with a trading margin of 4 paise/unit, traders can make handsome profits. For the above reasons, Commission G thought it fit to make the impugned Regulations. It was further contended that the doctrine of colourable exercise of power was not applicable to decide the validity of subordinate legislation. 34. Learned counsel lastly submitted that the power of judicial review cannot be located in Section 121 of the Act. The H 664 SUPREME COURT REPORTS [2010] 3 S.C.R.

A power under Section 121 is different from the power under Section 111. According to the learned counsel, Section 121 empowers the tribunal to act only when the Commission is guilty of inaction in carrying out its statutory functions. The power to annul a legislative act cannot be read into Section 121. Even B the High Court cannot direct the Legislature to enact a law and, therefore, such power cannot be read into Section 121. In order to entertain a challenge, directly or collaterally, the tribunal must have jurisdiction which must be conferred by the statute anq since in the instant case tribunal is not vested with su9h a c jurisdiction, it is not open to the Appellants to place reliance on some of the English Judgments. Thus, the Appellate Tribunal is not qualified to go behind a regulation as framed by CERC and to examine whether it acted within the bounds of the statute while framing the regulation. D DETERMINATIONS:

35. On the above submissions, one of the questions which arises for determination is - whether trading margin fixation (including capping) under the 2003 Act can only be done by E an Order under Section 79(1)0) and not by Regulations under Section 178? According to the appellant(s) it can only be done by an Order under Section 79(1)0), particularly when under Section 178(2) power to make regulations is co-relatable to the functions ascribed to each Authority under the said 2003 Act. F 36. In every case one needs to examine the statutory context to determine whether a court or a tribunal hearing a case has jurisdiction to rule on a defence based upon arguments of invalidity of subordinate legislation or administrative act under it. There are situations in which · G Parliament may legislate to preclude such challenges in the interest of pFOmoting certainty about the legitimacy of, administrative acts on which the public may have to rely. 37. On the above analysis of various sections of the 2003 H Act, we find that the decision-making and regulation-making PTC INDIA LTD. v. CENTRAL ELECTRICITY 665 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

functions are both assigned to CERC. Law comes into A existence not only through legislation but also by regulation and litigation. Laws from all three sources are binding. According to Professor Wade', "between legislative and administrative functions we have regulatory functions". A statutory instrument, such as a rule or regulation, emanates from the exercise of B delegated legislative power which is a part of administrative process resembling enactment of law by the legislature whereas a quasi-judicial order comes from adjudication which is also part of administrative process resembling a judicial decision by a court of law. [See Shri Sitaram Sugar Co. Ltd. c v. Union of India and Ors. reported in (1990) 3 SCC 223).

38. Applying the above test, price fixation exercise is really legislative in character, unless by the terms of a particular statute it is made quasi-judicial as in the case of Tariff fixation under Section 62 made appealable under Section 111 of the D 2003 Act, though Section 61 is an enabling provision for the framing of regulations by CERC. If one takes "Tariff' as a subject-matter, one finds that under Part VII of the 2003 Act . actual determination/ fixation of tariff is done by the Appropriate Commission under Section 62 whereas Section 61 is the E enabling provision for framing of regulations containing generic propositions in accordance with which the Appropriate Commission has to fix the tariff. This basic scheme equally applies to subject-matter "trading margin" in a different statutory context as will be demonstrated by discussion hereinbelow. In F the case of Mis Narinder Chand Hem Raj and Ors. v. Lt. Governor, Administrator, Union Territory, Himachal Pradesh and Ors. reported in (1971) 2 SCC 747, this Court has held that power to tax is a legislative power which can be exercised by the legislature directly or subject to certain conditions. The G legislature can delegate that power to some other Authority. But the exercise of that power, whether by the legislature or by the delegate will be an exercise of legislative power. The fact tb~t the power can be delegated will not make it an administrative 1power or adjudicatory power. In the said judgment, it has been H

666 SUPREME COURT REPORTS [2010] 3 S.C.R.

A further held that no court can direct a subordinate legislative body or the legislature to enact a law or to modify the existing law and if Courts cannot so direct, much less the Tribunal, unless power to annul or modify is expressly given to it. In the case of Indian Express Newspapers (Bombay) Pvt. Ltd. and B Ors. v. Union of India and Ors. reported in (1985) 1 SCC 641, this Court held that subordinate legislation is outside the purview of administrative action, i.e., on the grounds of violation of rules of natural justice or that it has not taken into account relevant circumstances or that it is not reasonable. However, a c distiAction must be made between delegation of legislative function and investment of discretion to exercise a particular discretionary power by a statute. In the latter case, the impugned exercise of discretion may be considered on all grounds on which administrative action may be questioned such as non-application of mind, taking irrelevant matters into0 consideration etc. The subordinate legislation is, however, beyond the reach of administrative law. Thus, delegated legislation - otherwise known as secondary, subordinate or administrative legislation - is enacted by the administrative branch of the government, usually under the powers conferred E upon it by the primary legislation. Delegated legislation takes a number of forms and a number of terms - rules, regulations, by-laws etc; however, instead of the said labels what is· of significance is the provisions in the primary legislation which, in the first place, confer the power to enact administrative F legislation.· Such provisions are also called as "enabling provisions". They demarcate the extent of the administrator's legislative power, the decision-making power and the policy making power. However, any legislation enacted outside the terms of the enabling provision will be vulnerable_ to judicial G review and ultra vires.

39. Applying the above mentioned tests to the scheme of 2003 Act, we find that under the Act, the Central Commission is a decision-making as well as regulation-making authority, H simultaneously. Section 79 delineates the functions of the PTC INDIA LTD. v. CENTRAL ELECTRICITY 667 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] Central Commission broadly into two categories - mandatory A functions and advisory functions. Tariff regulation, licensing (including inter-State trading licensing), adjudication upon disputes involving generating companies or transmission licensees fall under the head "mandatory functions" whereas advising Central Government on formulation of National B Electricity Policy and tariff policy would fall under the head "advisory functions". In this sense, the Central Commission is the decision-making authority. Such decision-making under Section 79(1) is not dependant upon making of regulations under Section 178 by the Central Commission. Therefore, c functions of Central Commission enumerated in Section 79 are separate and distinct from function of Central Commission under Section 178. The former is administrative/adjudicatory function whereas the latter is legislative. ·

40. As stated above, the 2003 Act has been enacted in D furtherance of the policy envisaged under the Electricity Regulatory Commissions Act, 1998 as it mandates establishment of an independent and transparent Regulatory Commission entrusted with wide ranging responsibilities and objectives inter alia including protection of the consumers of E electricity. Accordingly, the Central Commission is set up under Section 76(1) to exercise the powers conferred on, and in discharge of the functions assigned to, it under the Act. On reading Sections 76(1) and 79(1) one finds that Central Commission is empowered to take measures/steps in F discharge of the functions enumerated in Section 79( 1) like to regulate the tariff of generating companies, to regulate the inter-state transmission of electricity, to determine tariff for inter-state transmission of electricity, to issue licenses, to adjudicate upon disputes, to levy fees, to specify the Grid Code, to fix the G trading margin in inter-State trading of electricity, if considered necessary, etc .. These measures, which the Central Commission is empowered to take, have got to be in conformity with the regulations under Section 178, wherever such regulations are applicable. Measures under Section H 668 SUPREME COURT REPORTS (2010] 3 S.C.R.

A 79(1 ), therefore, have got to be in conformity with the regulations under Seqtion 178. To regulate is an exercise which is different from making of the regulations. However, making of a regulation under Section ·178 is not a pre-condition to the Central Commission taking any steps/measures under Sectiorr B 79(1). As stated, if there is a regulation, then the measure under Section 79(1) has to be in conformity with such regulation under Section 178. This principle flows from various judgments of this Court which we have discussed hereinafter. For example, under Section 79(1)(g) the Central Commission is required to levy c fees for the purpose of the 2003 Act. An Order imposing regulatory fees could be passed even in the absence of a· regulation under Section 178. If the levy is unreasonable, it could be the subject matter of challenge before the Appellate Authority under Section 111 as the levy is imposed by an Order/ decision making process. Making of a regulation under Section0 178 is not a pre-condition to passing of an Order levying a regulatory fee under Section 79(1)(g). However, if there is a regulation under Section 178 in that regard then the Order levying fees under Section 79(1)(g) has to be in consonance with such regulation. Similarly, while exercising the power to E frame the terms and conditions for determination of tariff under Section 178, the Commission has to be guided by the factors specified in Section 61. It is open to the Central Commission to specify terms and conditions for determination of tariff even in the absence of the regulations under Section 178. However, F if a regulation is made under Section 178, then, in that event, framing of terms and conditions for determination of tariff under Section 61 has to be in consonance with the regulation under Section 178. One must keep in mind the dichotomy between the power to make a regulation under Section 178 on one hand G and the various enumerated areas in Section 79(1) in which the Central Commission is mandated to take such measures as it deems fit to fulfil the objects of the 2003 Act. Applying this test to the-,,resent controversy, it becomes clear that one such area enumerated in Section 79(1) refers to fixation of trading H margin. Making of a regulation in that regard il? not a pre-PTC INDIA LTD. v. CENTRAL ELECTRICITY 669

REGULATORY COMM. THR. SECRY. (S.H. KAPADIA, J.] condition to the Central Commission exercising its powers to A fix a trading margin under Section 79(1 )0), however, if the Central Commission in an appropriate case, as is the case herein, makes a regulation fixing a cap on the trading margin under Section 178 then whatever measures a Central Commission takes under Section 79(1 )(j) has to be in B conformity with Section 178. One must understand the reason why a regulation has been made in the matter of capping the trading margin under Section 178 of the Act. Instead of fixing a trading margin (including capping) on a case to case basis, the Central Commission thought it fit to make a regulation which C has a general application to the entire trading activity which has been recognized, for the first time, under the 2003 Act. Further, it is impprtant to bear in mind that making of a regulation under Section 178 became necessary because a regulation made under Section 178 has the effect of interfering and overriding 0the existing contractual relationship between the regulated entities. A regulation under Section 178 is in the nature of a subordinate Legislation. Such subordinate Legislation can even override the existing contracts including Power Purchase Agreements which have got to be aligned with the regulations under Section 178 and which could not have been done across E the board by an Order of the Central Commission under Section 79(1)0).

41. To elucidate, we may refer to the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) F Regulations, 2004. The said Regulations have been made under Section 178 of the 2003 Act. Regulation 15 deals with various components of tariff. It includes Advance Against Depreciation ("AAD" for short). Regulations 21 (1 )(ii) and 38(ii) deal with computation of depreciation including AAD. Recently, G this concept of AAD came for consideration before this Court in the case of National Hydroelectric Power Corporation Ltd. v. CIT reported in 2010 (1) SCALE 5. AAD was suggested by the Central Commission as part of the tariff in order to overcome the cash flow problems faced by Central Power H 670 SUPREMli COURT REPORTS [2010] 3 S.C.R.

A Sector Utilities for meeting loan repayment obligations. The important point to be noted is that although under Section 61 of the 2003 Act the Central Commission is empowered to specify AAD as a condition for determination of the tariff, the Central Commission in its wisdom thought it fit to bring in the concept of AAD by enacting a regulation under Section 178 8 giving the benefit of AAD across the board to all Central Power Sector Utilities. In other words, instead of giving the benefit of AAD on a case to case basis under Section 61, the Central Commission decided to make a specifii; regulation giving C benefit of AAD across the board to all Central Power Sector Utilities. There is one more reason why a regulation under Section 178 with regard to AAD had to be made by CERC. Under the 2003 Act, the Central Commission is empowered under Section 61 to include depreciation as an item in the computation of tariff. However, if the rate of depreciation D envisaged by the Central Commission under the 2003 Act is different from the rate(s) of depreciation prescribed under Schedule XIV of the Companies Act, 1956 then such differential rate can be prescribed under the 2003 Act only by way of regulation under Section 178 of the 2003 Act which is in the E nature of subordinate legislation. It is important to note that the Companies Act, 1956 constitutes a law applicable to companies. It prescribes the format of Balance Sheet in Schedule VI. It prescribes the requirements as to Profit and Loss account vide Part II of Schedule VI. It also prescribes the F rates of depreciation vide Schedule XIV. If a different rate is required to be prescribed under the 2003 Act, then it could be done only by way of subordinate legislation, which is "' contemplated by Regulations framed under Section 178 of the 2003 Act. Similarly, profits earned by a trading company are G not only required to be presented in the manner indicated under the Companies Act but it is also required to be computed under the Income-tax Act, 1961. If such profits/income of a trading company is required to be capped under the 2003 Act, it can .. only be done by a subordinate legislation made under Section H · 178 of the 2003 Act. Accrual of income/profit under the PTC INDIA LTD. v. CENTRAL ELECTRICITY 671

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] Companies Act, 1956 or the Income-tax Act, 1961 can only be A curbed by a regulation made under the authority of subordinate legislation or primary legislation. This is exactly what is sought to be achieved by the impugned Regulation.

42.-0ne more-citation may be noticed. Reserve Bank of B India is a Regulator under the RBI Act, 1934 ("1934 Act"). Under the 1934 Act; RBI is empo\vered not only to regulate banks but also financial institutions, NBFCs etc .. Chapter Ill B of the 1934 Act deals with provisions relating to financial institutiohs and NBFCs receiving deposits from the public. Under Section 45JA C of the 1934 Act, RBI is given the power to determine policy and issue directions to NBFCs and financial. institutions in public · interest or in order to regulate the financial system of the country. Section 45JA, however, is confined to Chapter Ill B. However, under Section 58, which falls in Chapter IV, dealing with general provisions, the Board of Directors of RBI are given the power D to make regulations consistent with the 1934 Act to provide for all matters for which provision is necessary. The principle of "generality versus enumeration" is also applicable to Section 58 of RBI Regulations because under Section 58(2) there is a list of topics enumerated on which regulations could be made. E In other words, Section 58 (1), (2) of the 1934 Act is similar to Section 178 (1), (2) of the 2003 Act. Recently, before the Division Bench of this Court, the question arose, inter alia, as to the' accounting treatment to be given by NBFCs accepting deposits from the public in the context of provision to be made F for Non Performing Assets ("NPAs"). An Order was passed by RBI under Section 45JA of the 1934 Act stating that although provision for doubtful debts is required to be reduced from the assets' side of the balance sheet under the provisions of the Companies Act, 1956, for proper disclosure under the 1934 G Act, such a provision should be shown in the balance sheet specifically on the liabilities' side. It is interesting to note that the Order was passed under Section 45JA which, as stated above, is part of Chapter Ill B of the 1934 Act, which chapter expressly deals with provisions relating to NBFCs. There was H

672 SUPREME COURT REPORTS [2010] 3 S.C.R A no regulation enacted under Section 58 on the topic, namely, NPAs. The point to be noted is, that there could be an Order/ decision of a regulator under the Act even in the absence of regulations. RBI like CERC is a regulator under the 1934 Act. Under Section 45JA it is empowered to issue directions in B contradistinction to its powers to enact regulations. under Section 58 of the 1934 Act. Giving directions under Section 45JA need not be preceded by regulations made under Section 58, however, if in a given case, RBI/Board would have enacted a regulation on making of provision for NPAs under Section 58 c then the Order of RBI under Section 45JA of the 1934 Act was required to be in conformity with the said regulations. (See the judgment of this Court in the case of Mis Southern Technologies Ltd. v. Joint Commissioner of Income Tax, Coimbatore reported in 2010 (1) SCALE 329.)

D 43. The above two citations have been given by us only to demonstrate that under the 2003 Act, applying the test of "general application", a Regulation stands on a higher pedestal vis-a-vis an Order (decision) of CERC in the sense that an Order has to be in conformity with the regulations. However, that E would not mean that a regulation is a pre-condition to the order (decision). Therefore, we are not in agreement with the contention of the appellant(s) that under the 2003 Act, power to make regulations under Section 178 has to be correlated to the functions ascribed to each authority under the 2003 Act and F that CERC can enact regulations only on topics enumerated in Section 178(2). In our view, apart from Section 178(1) which deals with "generality" even under Section 178(2)(ze) CERC could enact a regulation on any topic which may not fall in the enumerated list provided such powedalls within the scope of G 2003 Act. Trading is an activity recognized under the said 2003 Act. While deciding the nature of an Order (decision) vis-a-vis a Regulation under the Act, one needs to apply the test of general application. On the making of the impugned Regulations 2006, even the existing Power Purchase H Agreements ("PPA") had to be modified and aligned with the PTC INDIA LTD. v. CEN'rRAL ELECTRICITY 673 ' . 1 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.)

said Regulations. In other words, the impugned Regulation A makes an inroad into even the existing contracts. This itself indicates the width of the power conferred on CERC under Section 178 of the 2003 Act. All contracts coming into existence after making of the impugned Regulations 2006 have also to factor in the capping of the trading margin. This itself indicates B that the impugned Regulations are in the nature of subordinate legislation. Such regulatory intervention into the existing contracts across-the-board could have been done only by making Regulations under Section 178 and not by passing an Order under S~ction 79(1 )0) of the 2003 Act. Therefore, in our c view, if we keep the above discussion in mind, it becomes clear that the word "order'' in Section 111 of the 2003 Act cannot include the impugned Regulations 2006 made under Section 178 .of the 2003 Act. D 44. We may usefully refer to some decisions relevant in the context.

45. In the case of City Board, Mussoorie v. State Electricity Board and Ors., reported in AIR (58) 1971 Allahabad 219, the matter arose under Electricity (Supply) Act, E 1948 ("1948 Act"). Under that Act, Grid Tariff had to be fixed from time to time under Section 46(1) "in accordance with any regulations made in that behalf'. Under Section 79 of the 1948 Act, the Board was also given the power to make regulations not inconsistent with the Act and the Rules made thereunder F to provide for all or any of the matters enumerated therein. It was argued on behalf of the appellant that the regulations must exist before a Grid Tariff can be fixed. This argument was rejected by the High Court which held that there was nothing in the 1948 Act to suggest that existence of a regulation was a G pre-condition to the determination of a grid tariff. It was held that under Section 46 of 1948 Act, the Board was given a wide discretion to frame the grid tariff depending upon various factors mentioned in the Act. According to the High Court, Section 46 of the Act was a standalone provision, therefore, the grid tariff H 674 SUPREME COURT REPORTS (2010] 3 S.C.R.

A could be fixed even in the absence of the regulations provided such fixation is not inconsistent with the 1948 Act. However, it was further observed that if the Board had made regulations under Section 79 then order framing the grid tariff under Section 46(1) had to conform to such regulations. This view stood B affirmed by this Court in the case of U.P. State Electricity Board, Lucknow v. City Board, Mussoorie, reported in (1985) 2 sec 16.

46. A similar question arose for determination by this Court C in the case of Mis Jagdamba Paper Industries (Pvt.) Ltd. and Ors. v. Haryana State Electricity Board and Ors., reported in AIR 1983 SC 1296. In that case, enhancement in the security for meters and for payment of energy bills came to be challenged. It was argued on behalf of the appellants that the Board had not framed any Regulations under Section 79 of the D 1948 Act for such enhancement. According to the appellants, the supply of electricity was controlled under an agreement between the Board and the appellants and therefore unilateral escalation of security charges by passing of an Order under Section 49 would be contrary to any acceptable notion of E contract. It was contended that under Section 49(1) of the 1948 Act, the Board was conferred with statutory powers to determine the conditions on the basis of which supply had to be made. Therefore, without determining the conditions under Section 49(1), it was not open to the Board to unilaterally enhance the F security charges contrary to the existing contract between the Board and the consumers. This argument was rejected by this Court which held that what apply to the tariff fixation. would equally apply to the security. Section 49(1) of the 1948 Act clearly indicated that the Board may supply electricity to any G person upon such terms and conditions as the Board thinks fit. It was held that since the contract between the consumer and the Board contemplated enhancement of security charges as a condition of supply of electricity, it was not open to the appellants to say that such enhancement cannot take place H without regulations being framed under Section 79. This PTC INDIA LTD. v. CENTRAL ELECTRICITY 675

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] judgment is important from another angle also. It indicates that A regulations under Section 79 of 1948 Act were to be in the nature of subordinate legislation, therefore, all contracts had to be in terms of such regulations. In the present case also, if one examines the terms and conditions of the licences, power to fix trading margin is expressly contemplated by such terms. The B said judgment further held that the Board is a statutory authority and has to act within the framework of the 1948 Act. If the act of the Board is not in consonance or in breach of some statutory provisions of law, rule or regulation, it is always open to challenge in a petition under Section 226 of the Constitution. c

47. In the case of Kera/a State Electricity-Board v. S.N. Govinda Prabhu and Bros. and Ors., reported in (1986) 4 sec 198, the dispute was confined to the question concerning increase in the electricity tariff by the Board under the 1948 Act. 0The principal ground of challenge was that the Board had acted outside its statutory authority by formulating a price structure intended to yield sufficient revenue to offset not only the actual expenditure as contemplated by Section 59 of the 1948 Act but also expenditure not covered by that section. At this stage, we may point out that, in all these cases, the Supreme Court has E considered tariff fixation, price fixation, security charges fixation at par. In that case, one of the submissions which found favour. with the High Court, which accepted the submissions of the consumer, while striking down the impugned notification, was that in the absence of specification by the State Government, F it was not open to the Board to adjust the tariffs. What was found by the Supreme Court was that although the expenditure did not fall strictly within Section 59 of the 1948 Act, the actual expenditure stood incurred to avoid the loss. Therefore, the Supreme Court gave a schematic interpretation to the 1948 Act G and it held that the State Electricity Board was obliged to carry on its business economically and efficiently and consequently such charges were admissible even though they did not fall strictly within the ambit of Section 59. On the question as to absence of specification by the State Government, this Court H

676 SUPREME COURT REPORTS [2010] 3 S.C.R. A . further held that the omission of the rule-making authority to · frame rules cannot takeaway the right to factor in such expenses in the revised tariff structure. This judgment is one more case which indicates that making of regulations is not a pre-condition to the tariff fixation or price fixation or security B charges fixation.

48. In the case of Hindustan Zinc Ltd. etc. v. Andhra Pradesh State Electricity Board and Ors. reported in (1991) 3 SCC 299, the main attack was to the upward revision of the C tariffs for HT consumers in the writ petition before the High Court, inter alia, on the ground that the Board cannot generate a surplus in excess of the surplus specified under Section 59 of the 1948 Act. Section 59 of that Act gave power to the Board to lay down general principles for Board's finance. It was also contended that the tariff revision was made without prior D consultation with the State Electricity Consultative Council as required by Section 16(5) of the 1948 Act. It was held by this Court that even in the absence of general principles being specified under Section 59 of that Act, it was open to the Board to generate a surplus in order to carry on the business in a more E efficient and economic manner. Following the judgment in the case of S.N. Govinda Prabhu (supra), it was held that even in the absence of prior consuitation with the State Electricity Consultative Council as required by Section 16(5), it was open to the Board which was vested with the power of tariff fixation F to make an upward revision of tariff. In other words, specification by. making rules or regulations was not a pre-condition for upward revision of tariff. It was observed that, if in a given case, it is found that such upward revision was arbitrary, then under the judicial review jurisdiction it was open to the G courts to strike down such upward revision as arbitrary under Article 14. It was further observed that the "laying down procedure" before the Legislature was meant to effectively control the exercise of the delegated power of the Board, however, such laying down procedure will not make the H impugned regulation immune from judicial review. (Also see the PTC INDIA LTD. v. CENTRAL ELECTRICITY 677

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] judgment of this Court in Indian Express Newspapers A (Bombay) Pvt. Ltd. and Ors. v. Union of India and Ors. reported in (1985) 1 sec 641. !)aragraphs 75 to 79). 49. On the question of "generality versus enumeration" principle, it was further held in the case of Hindustan Zinc Ltd. B (supra) that under Section 49(1) of the 1948 Act a general power was given to the Board to supply electricity to any person not being a licensee upon such terms and conditions as the Board thinks fit and the Board may for the purposes of such supply frame uniform tariffs under Section 49(2). The Board was required to fix uniform tariffs after taking into account certain C enumerated factors. It was held that the power of fixation of tariffs in the Board ordinarily had to be done in the light of specified factors, however, such enumerated factors in Section 49(2) did not prevent the Board from fixing uniform tariffs on factors other than those enumerated in Section 49(2) as long D as they were relevant and in consonance with the Act. To the same effect is the judgment of this Court in Shri Sitaram Sugar . Co. Ltd. (supra). In that judgment also this Court held that the enumerated factors/topics in a provision do not mean that the authority cannot take any other matter into consideration which E may- be relevant. The words in the enumerated provision are not a fetter; they are not words of limitation, but they are words for general guidance.

50. One more s..;pect needs to be mentioned. The F judgment of this Court in Shri Sitaram Sugar Co. Ltd. (supra) has laid down various tests to distinguish legislative from ·administrative functions. It further held that price fixation is a legislative function unless the statute provides otherwise. It also laid down the scope of judicial review in such cases. G 51. Applying the above judgments to the present case, it is clear that fixation of the trading margin in the inter-State trading of electricity can be done by making of regulations under Section 178 of 2003 Act. Power to fix the trading margin H 678 SUPREME COURT REPORTS [2010] 3 S.C.R. A under Section 178 is, therefore, a legislative power and the Notification issued under that section amounts to a piece of subordinate legislation, which has a general application in the sense that even existing contracts are required to be modified in terms of the impugned· Regulations. These Regulations make B an inroad into contractual relationships between the parties. Such is the scope and effect of the impugned Regulations which could not have taken place by an Order fixing the trading margin under Section 79(1)U). Consequently, the impugned Regulations cannot fall within the ambit of the word "Order" in c Section 111 of the 2003 Act.

52. Before concluding on this topic, we still need to examine the scope of Section 121 of the 2003 Act. In this case, appellant(s) have relied on Section 121 to locate the power of judicial review in the Tribunal. For that purpose, we must notice · D the salient features of Section 121. Under Section 121, there must be a failure by a Commission to perform its statutory function in which event the Tribunal is given authority to issue orders, instructions or directions to the Commission to perform its statutory functions. Under Section 121 the Commission has E to be heard before such orders, instructions or directions can be issued. 53. The main issue which we have to decide is the nature of the power under Section 121. lri the case of Mis Raman and F Raman Ltd. v. State of Madras and Ors. reported in AIR 1959 SC 694, Section 43A of Motor Vehicles Act, 1939, ("1939 Act"), as amended by Madras Act 20 of 1948, came for consideration before the Supreme Court. Section 43A conferred power on the State Government to issue "orders" and G "directions", as it may consider necessary in respect of any matter relating to road transport to the State Transport Authority or a Regional Transport Authority. The meaning of the words "orders" and "directions" came for interpretation before the Supreme Court in the said case. It was held, on examination H of the Scheme of the Act, that Section 43A was placed by the PTC INDIA LTD. v. CENTRAL ELECTRICITY 679

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

legislature before the sections conferring quasi-judicial powers A on Tribunals which clearly indicated that the authority conferred under Section 43A was confined to administrative functions of the Government and the Tribunals rather than to their judicial functions. It was further held that the legislature had used two words in the section: (i) orders; and (ii) directions. This Court s further noticed that under the 1939 Act there was a separate Chapter which dealt with making of "rules" which indicated that the words "orders" and "directions" in Section 43A were meant to clothe the Government-with the authority to issue directions of administrative character. It was held that the source of power c did not affect the character of acts done in exercise of that power. Whether it is a law or an administrative direction depends upon the character or nature of the orders or directions authorized to be issued in exercise of the power conferred. It was, therefore, held that the words "orders" and "directions" 0were not laws. They were binding only on the Authorities under the Act. Such orders and directions were not required to be published. They were not kept for scrutiny by legislature. It was further held that such orders and directions did not override the discretionary powers conferred on an authority under Section E60 of the 1939 Act. It was observed that non compliance of such orders, instructions and directions may result in taking disciplinary action but they cannot affect a finding given by the quasi-judicial authority nor can they impinge upon the rules enacted by the rule-making authority. It was held that such Forders and directions would cover only an administrative field of the officers concerned and therefore such orders and directions do not regulate the rights of the parties. Such orders and directions cannot add to the considerations/topics prescribed under Section 47 of the 1939 Act on the basis of which an adjudicatir:ig authority is empowered to issue or refuse G permits, as the case may be.

54. Applying the tests laid down in the above judgment to the present case, we are of the view that, the words "orders", "instructions" or "directions" in Section 121 do not confer power H 680 SUPREME COURT REPORTS [2010] 3 S.C.R.

A of judicial review in the Tribunal. It is not possible to lay down any exhaustive list of cases in which there is failure in performance of statutory functions by Appropriate Commission. However, by way of illustrations, we may state that, under Section 79(1)(h) CERC is required to specify Grid Code having B regard to Grid Standards. Section 79 comes in Part X. Section 79 deals with functions of CERC. The word "grid" is defined in Section 2(32) to mean high voltage backbone system of interconnected transmission lines, sub-station and generating plants. Basically, a grid is a network. Section 2(33) defines "grid c code" to mean a code specified by CERC under Section 79(1 )(h). Section 2(34) defines "grid standards" to mean standards specified under Section 73(d) by the Authority. Grid Code is a set of rules which governs the maintenance of the network. This maintenance is vital. In summer months grids tend to trip. In the absence of the making of the Grid Code in0 accordance with the Grid Standards, it is open to the Tribunal to direct CERC to perform its statutory functions of specifying the Grid Code having regard to the Grid Standards prescribed by the Authority under Section 73. One can multiply these illustrations which exercise we do not wish to undertake. Suffice E it to state that, in the light of our analysis of the 2003 Act, hereinabove, the words orders, instructions or directions in Section 121 of the 2003 Act cannot confer power of judicial review under Section 121 to the Tribunal, which, therefore, cannot go into the validity of the impugned Regulations 2006, F as rightly held in the impugned judgment.

55. One of the contentions raised by Shri Shanti Bhushan, learned senior counsel appearing on behalf of Calcutta Electricity Supply Company Ltd. needs to be considered. It was G contended on behalf of CESC Ltd. that under Section 111 of the 2003 Act, an appeal lies only against an Order by the Appropriate Commission and not against Regulations framed by CERC under Section 178 of the 2003 Act. It was contended that Regulations under Section 178 are framed in exercise of H delegated power in which there was an element of legislative . i PTC INDIA LTD. v. CENTRAL ELECTRICITY 681 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

function. That, the Regulations framed by CERC are required A to be laid before the Parliament under Section 179 of the 2003 Act. The said Regulations could be modified by the two Houses of the Parliament. In the circumstances, it was, therefore, contended that neither Section 111 nor Section 121 would be deemed to have conferred any power on the Appellate Tribunal B for Electricity to supervise or sit in judgment over the Regulations. To this extent, learned counsel supported the contentions of the learned Solicitor General, appearing on behalf of CERC (respondent no.1). Further, an interesting argument was advanced by the learned counsel, namely, that, c Section 121 of the 2003 Act has not yet been brought into force. In this connection, reference was made to Section 1(3) of the 2003 Act as well as to the notification dated 10.6.2003 issued under Section 1(3) of the 2003 Act by which the Central Government had fixed 10.6.2003 as the date on which Sections 0 1 to 120 and Sections 122 to 185 were brought into force, however, Section 121 was not brought into force till Notification dated 27 .1.2004, which brought into force Electricity (Amendment) Act 2003 (No.57 of 2003) came to be issued. According to the learned counsel, Section 4 of the Electricity E (Amendment) Act, 2003 (No.57 of 2003) which was brought into force on 27.1.2004 merely provided for substitution of the original Section 121 with new Section 121, without issuance of a further notification under Section 1(3) of the original Electricity Act, 2003. According to the learned counsel, there Fis a differencs between substituting a dormant Section iri an Act and in bringing a substituted section into force which has not been done in this case and, therefore, Section 121, although being part of the statute, is not brought into force, till today. To answer the above contention, we need to quote Section 1(3) and also Section 121 of the original Electricity Act, 2003 which G was not brought into force though, as stated above, Sections 1 to 120 and Sections 122 to 185 were brought into force vide notification dated 10.6.2003:

H 682 SUPREME COURT REPORTS [2010] 3 S.C.R. A "Section 1.

"Section 121. Power of Chairperson of Appellatec Tribunal.- The Chairperson of the Appellate Tribunal shall exercise general power of superintendence and control over the appropriate Commission." 56. We also quote hereinbelow Sections 1 and 4 of the D Electricity (Amendment) Act, 2003 (No.57 of 2003) which was brought into force on 27.1.2004: "Section 1. (2) It shall come into force on such date as the Central Government may, by notification in the Official E Gazette, appoint. Section 4. For Section 121 of the principal Act, the following Section shall be substituted, namely:-"121. Power of Appellate Tribunal F The Appellate Tribunal may, after hearing the Appropriate Commission or other interested party, if any, from time to time, issue such orders, instructions or directions as it may deem fit, to any Appropriate Commission for the G performance of its statutory functions under this Act."

57. As stated above, the Electricity (Amendment) Act, 2003 (No.57 of 2003) was brought into force by Notification dated 27.1.2004 which is reproduced hereinbelow: H PTC INDIA LTD. v.

58. In our view, there is no merit in the above contention advanced on behalf of CESC Ltd. At the outset, we may state that material brought on record indicates that Section 121 of the original Electricity Act, 2003, quoted hereinabove, was D never brought into force because some MPs expressed the concern that the power, under that section, conferred upon the Chairperson of the Appellate Tribunal, could lead to excessive centralization of power and interference with the day-to-day activities of the Commission by the Chairperson of the Tribunal. E Therefore, Section 121 was amended by Electricity (Amendment) Act, 2003 (No.57 of 2003) which is also quoted hereinabove and which amendment Act came into force from 27.1.2004. In our view, by necessary implication of the coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force, hence, F there is no requirement for a further notification under Section 1(3), particularly when Section 121 in its amended form has come into force w.e.f. 27.1.2004. In this connection, it may be seen that Section 121 of the original Act stood substituted by Amendment Act No.57 of 2003. Substitution of a provision G results in repeal of the earlier provision and its replacement by the new provision. Substitution is a combination of repeal and fresh enactment. [See: Principles of Statutory Interpretation by G.P. Singh, 11th Edn., p. 638]. Section 121 of the original Electricity Act, 2003 was never brought into force. It was H

684 SUPREME COURT REPORTS [2010] 3 S.C.R. A substituted by new Section 121 by Amendment Act No.57 of 2003 which was brought into force by a notification dated 27.1.2004. Substitution, as stated above, results in repeal of the old provision and replacement by a new provision. Applying these tests to the facts of the present case, we find that the B Electricity (Amendment) Act, 2003 (No.57 of 2003) was brought into force by notification dated 27.1.2004. That, notification was issued under Section 1 (2) of the Electricity (Amendment) Act, 2003 (No.57 of 2003). If one reads Section 1(2) of Electricity (Amendment) Act, 2003 (No.57 of 200:.=,) with Notification dated c 27.1.2004 issued under Section 1 (2) of the amended Act, 2003, it becomes clear that on coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force. Hence, there was no requirement for a further notification under Section 1 (3), consequently, Section 121 in its amended form came into force0 with effect from 27.1.2004. 59. Summary of Our Findings: (i) In the hierarchy of regulatory powers and functions E under the 2003 Act, Section 178, which deals with making of regulations by the Central Commission, under the authority of subordinate legislation, is wider than Section 79( 1) of the 2003 Act, which enumerates the regulatory functions of the Central Commission, in specified areas, to be dischargedF by Orders (decisions).

(ii) A regulation under Section 178, as a part of regulatory framework, intervenes and even overrides the existing contracts between the G regulated entities inasmuch as it casts a statutory obligation on the regulated entities· to align their existing and future contracts with the said regulations. H (iii) A regulation under Section 178 is made under the PTC INDIA LTD. v. CENTRAL ELECTRICITY 685 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] authority of delegated legislation and consequently A its validity can be tested only in judicial review proceedings before the courts and not by way of appeal before the Appellate Tribunal for Electricity under Section 111 of the said Act. B (iv) Section 121 of the 2003 Act does not confer power of judicial review on the Appellate Tribunal. The words "orders", "instructions" or "directions" in Section 121 do not confer power of judicial review in the Appellate Tribunal for Electricity. In this C judgment, we do not wish to analyse the English authorities as we find from those authorities that in certain cases in England the power of judicial review is expressly conferred on the Tribunals constituted under the Act. In the present 2003 Act, the power of judicial review of the validity of the D Regulations made under Section 178 is not conferred on the Appellate Tribunal for Electricity.

(v) If a dispute arises in adjudication on interpretation of a regulation made under Section 178, an appeal E would certainly lie before the Appellate Tribunal under Section 111, however, no appeal to the Appellate Tribunal shall lie on the validity of a regulation made under Section 178. (vi) Applying the principle of "generality versus F enumeration", it would be open to the Central Commission to make a regulation on any residuary item under Section 178( 1) read with Section 178(2)(ze). Accordingly, we hold that the CERC was empowered to cap th~ trading margin under G the authority of delegated legislation under Section 178 vide the impugned notification dated 23.1.2006. (vii) Section 121, as amended by Electricity H "l ~.~·~\". 686 _ SUPREME COURT REPORTS [2010] 3 S.C.R. A (Amendment) Act 57 of 2003, came into force with effect from 27.1.2004. Consequently, there is no merit in the contention advanced that the said section is not yet been brought into force. B Conclusion: 60. For the aforesaid reasons, we answer the question raised in the reference as follows: The Appellate Tribunal for Electricity has no jurisdiction to c decide the validity of the Regulations framed by the Central Electricity Regulatory Commission under Section 178 of the Electricity Act, 2003. The validity of the Regulations may, however, be challenged by seeking judicial review under Article 226 of the Constitution of India.

D Our summary of findings and answer to the reference are with reference to the provisions of the Electricity Act, 2003. They shall not be construed as a general principle of law to be applied to Appellate Tribunals vis-a-vis Regulatory Commissions under other enactments. In particular, we make E it clear that the decision may not be taken as expression of any view in regard to the powers of Securities Appellate Tribunal vis-a-vis Securities and Exchange Board of India under the Securities and Exchange Board of India Act, 1992 or with reference to the Telecom Disputes Settlements and Appellate F Tribunal vis-a-vis Telecom Regulatory Authority of India under the Telecom Regulatory Authority of India Act, 1997. 61. In view of our findings, we dismiss these appeals as having no merit with no order as to costs, G K.K.T. Appeals dismissed.

The Tribunal dismissed the appeals holding that its jurisdiction was restricted by0 the limits imposed by the parent Statute, i.e., the Electricity Act, 2003. The Tribunal held that the appropriate course of action for the appellants was to proceed by way of judicial review under the Constitution of India. Hence the present appeals. E The questions for consideration before the Court were: (i) Whether the Appella~e Tribunal constituted under the 2003 Act has jurisdiction u/s. 111 of the Act, to examine the validity of the 2006 Regulations (ii) Whether F capping of trading margins could be done by the Central Electricity Regulatory Commission (CERC) by making a Regulation in that regard u/s. 178 of 2003 Act and (iii) Whether Parliament has conferred power of judicial review on the Appellate Tribunal for Electricity u/s. 121 of G the 2003 Act.

Dismissing the appeals, the Court HELD: 1.1. A regulation u/s. 178 is made under the authority of delegated legislation and consequently its H PTC INDIA LTD. v. CENTRAL ELECTRICITY 611 REGULATORY COMM. THR. SECRY. validity can be tested only in judicial review proceedings A before the courts and not by way of appeal before the Appellate Tribunal for Electricity under Section 111 of Electricity Act, 2003. [Para 59] [684-H; 685-A] 1.2. The decision-making and regulation-making 8functions are both assigned to CERC. Law comes into existence not only through legislation but also by regulation and litigation. Laws from all three sources are binding. A statutory instrument, such as a rule or regulation, emanates from the exercise of delegated legislative power which is a part of administrative process C resembling enactment of law by the legislature whereas a quasi-judicial order comes from adjudication which is also part of administrative process resembling a judicial decision by a court of law. [Para 37] [664-H; 655-A-C] D Shri Sitaram Sugar Co. Ltd. v. Union of India and Ors. (1990) 3 sec 223, referred to.

1.3. Price fixation exercise is actually legislative in character, unless by the terms of a particular statute it is E made quasi-judicial as in the case of Tariff fixation u/s. 62 made appealable u/s. 111 of the 2003 Act, though Section 61 is an enabling provision for the framing of regulations by CERC. If one takes "Tariff'' as a subject-matter, one finds that under Part VII of the 2003 Act actual determination/ fixation of tariff is done by the appropriate F Commission u/s. 62, whereas Section 61 is the enabling provision for framing of regulations containing generic propositions in accordance with which the appropriate Commission has to fix the tariff. This basic scheme equally applies to subject-matter "trading margin" in a G different statlltory context. [Para 38] [665-D-F] 1.4. Section 79 delineates the functions of CERC broadly into two categories - mandatory functions and advisory functions. Tariff regulation, licensing (Including H 612 SUPREME COURT REPORTS [2010) 3 S.C.R.

A inter-State trading licensing), adjudication upon disputes involving generating companies or transmission licensees fall under the head "mandatory functions" whereas advising Central Government on formulation of National Electricity Policy and tariff policy would fall B under the head "advisory_ functions". In this sense, CERC is the decision-making authority. Such decision-making u/s. 79 (1) is not dependant upon making of regulations u/s. 178 by CERC. Therefore, functions of CERC enumerated in Section 79 are separate and distinct from c function of CERC u/s. 178. The former is administrative/ adjudicatory function whereas the latter is legislative. [Para 39) [666-H; 667-A-C) Mis. Narinder Chand Hem Raj and Ors. v. Lt. Governor, Administrator, Union Territory, Himachal Pradesh and Ors. D (1971) 2 SCC 747; Indian Express Newspapers (Bombay) Pvt. Ltd. and Ors. v. Union of India and Ors. (1985) 1 SCC 641, relied on.

1.5. On reading Sections 76(1) and 79(1) one finds E that CERC is empowered to take measures/steps in discharge of the functions enumerated in Section 79(1) like to regulate the tariff of generating companies, to regulate the inter-State transmission of electricity, to determine tariff for inter-State transmission of electricity, F to issue licenses, to adjudicate upon disputes, to levy fees, to specify the Grid Code, to fix the trading margin in inter-State trading of electricity, if considered necessary, etc .. These measures, which CERC is empowered to take, have got to be in conformity with the G regulations u/s. 178, wherever such regulations are applicable. Measures u/s. 79(1 ), therefore, laave got to be in conformity with the regulations u/s. 178. To regulate is an exercise which is different from making of the regulations. However, making of a regulation u/s. 178 is not a pre-condition to the Central Commission taking any H PTC INDIA LTD. v. CENTRAL ELECTRICITY 613 REGULATORY COMM. THR. SECRY. steps/measures u/s. 79(1 ). If there is a regulation, then the A measure u/s. 79(1) has to be in conformity with such regulation u/s. 178. The dichotomy between the power to make a regulation u/s. 178 on one hand and the various enumerated areas in Section 79(1) in which CERC is mandated to take such measures as it deems to fulfil the B objects of 2003 Act. [Para 40] [667-F-H; 668-A-C]

1.6. In the hierarchy of regulatory powers and functions under the 2003 Act, Section 178, which deals with making of regulations by the Central Commission, under the authority of subordinate legislation, is wider C than Section 79(1) of the 2003 Act, which enumerates the regulatory functions of the CERC, in specified areas, to be discharged by orders (decisions). [Para 59] [684-E-F] 1.7. In the instant case, instead of fixing a trading D margin (including capping) on a case to case basis, CERC thought it fit to make a regulation which has a general application to the entire trading activity which has been recognized, for the first time, under 2003 Act. Making of a regulation u/s. 178 became necessary E because a regulation made u/s. 178 has the effect of interfering and overriding the existing contractual relationship between the regulated entities. A regulation u/s. 178 is in the nature of a subordinate legislation. Such subordinate legislation can even override the existing F contracts including Power Purchase Agreements which have got to be aligned with the regulations u/s. 178 and which could not have been done across the board by an order of the CERC u/s. 79(1)(j). [Para 40] [669-8-E] National Hydro-electric Power Corporation Ltd. v. CIT G 2010 (1) SCALE 5; Mis Southern Technologies Ltd. v. Joint Commissioner of Income Tax, Coimbatore 2010 (1) SCALE 329, relied on. 1.8. Applying the test of "general application", a H 614 SUPREME COURT REPORTS [2010] 3 S.C.R.

A regulation stands on a higher pedestal vis-ii-vis an Order {decision) of CERC in the sense that an order has to be in conformity with the regulations. However, that would not mean that a regulation is a pre-condition to the order {decision). Therefore, it cannot be said that under the B 2003 Act, power to make regulations u/s. 178 has to be correlated to the functions ascribed to each authority under the 2003 Act and that CERC can enact regulations only on topics enumerated in s. 178(2). Apart from Section 178(1) which deals with "generality" even u/s. c 178{2){ze), CERC could enact a regulation on any topic which may not fall in the enumerated list provided such power falls within the scope of the 2003 Act. Trading is an activity recognized under the 2003 Act. While deciding the nature of an order {decision) vis-a-vis a regulation under the Act, one needs to apply the test of general0 application.

(1985) 1 SCC 641; City Board, Mussoorie v. State Electricity Board and Ors. AIR (58) 1971 Allahabad 21·9, referred to. G 1.9. On the making of the impugned Regulations 2006, even the existing Power Purchase Agreements {"PPA") had to be modified and aligned with the said Regulations. The impugned Regulation makes an inroad into even the existing contracts. This itself indicates the H width of the power conferred on CERC u/s. 178 of the . PTC INDIA LTD. v. CENTRAL ELECTRICITY 615 REGULATORY COMM. THR. SECRY. 2003 Act. All contracts coming into existence after making A of the impugned Regulations 2006 have also to factor in the capping of the trading margin. This itself indicates that the impugned Regulations are in the nature of subordinate legislation. Such regulatory intervention into the existing contracts across-the-board could have been B done only by making Regulations u/s. 178 and not by passing an Order u/s. 79(1)(j) of the 2003 Act. Therefore, it becomes clear that the word "order' in Section 111 of the 2003 Act cannot include the impugned Regulations 2006 made u/s. 178 of the 2003 Act. [Para 43] [672-H; 673- c A-DJ

1.10. If a dispute arises in adjudication on interpretation of a regulation made u/s. 178, an appeal would certainly lie before the Appellate Tribunal under Section 111, however, no appeal to the Appellate Tribunal D shall lie on the validity of a regulation made under Section 178. [Para 59J [685-E] 2.1. On the question of "generality versus enumeration" principle, the enumerated factors/topics in E a provision do not mean that the authority cannot take any other matter into consideration which may be relevant. The words in the enumerated provision are not a fetter; they are not words of limitation, but they are words for general guidance. [Para 49] [677-C-F] F Hindustan Zinc Ltd. etc. v. Aridhra Pradesh State Electricity Board and Ors. (1991) 3 SCC 299; Shri Sitaram Sugar Co. Ltd. v. Union of India and Ors. (1990) 3 SCC 223, relied on. G 2.2. Applying the principle of "generality versus enumeration", it would be open to the Central Commission to make a regulation on any residuary item u/s. 178(1) r/w Section 178(2)(ze). The CERC was empowered to cap the trading margin under the authority H 616 SUPREME COURT REPORTS [2010] 3 S.C.R. A of delegated legislation u/s. 178 vide the impugned Notification dated 23.1.2006. [Para 59] (685-F-G]

3.1. Section 121 of the 2003 Act does not confer power of judicial review on the Appellate Tribunal. The words "orders", "instructions" or "directions" in Section 8 121 do not confer power of judicial review in the Appellate Tribunal for Electricity. In the 2003 Act, the power of judicial review of the validity of the Regulations made u/ s. 178 is not conferred on the Appellate Tribunal for C Electricity. [Para 59] (685-B-D] Mis Raman and Raman Ltd. v. State of Madras and Ors. AIR 1959 SC 694, relied on. 3.2. It is not correct to say thats. 121 has not yet been o brought into force. At the outset, the material brought on record indicates that Section 121 of the original Electricity Act, 2003, was never brought into force because some MPs expressed the concern that the power, under that Section, conferred upon the Chairperson of the Appellate E Tribunal, could lead to excessive centralization of power and interference with the day-to-day activities of the Commission by the Chairperson of the Tribunal.

Therefore, Section 121 was amended by Electricity (Amendment) Act, 2003 (No.57 of 2003) and which F amendment Act came into force from 27.1.2004. By necessary implication of the coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force, hence there is no requirement for a further Notification u/s. 1(3), particularly when Section 121 in its amended form has G come into force w.e.f. 27.1.2004. Section 121 of the original Act stood substituted by Amendment Act No. 57 '' of 2003. Substitution of a provision results in repeal of the earlier provision and its replacement by the new provision.

The crucial points that arise for determination are: -H PTC INDIA LTD. v. CENTRAL ELECTRICITY 619 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] (i) Whether the Appellate Tribunal constituted under A the Electricity Act, 2003 ("2003 Act") has jurisdiction under Section 111 to examine the validity of Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, 2006 framed in exercise of power conferred under Section 178 of B the 2003 Act? (ii) Whether Parliament has conferred power of judicial review on the Appellate Tribunal for Electricity under Section 121 of the 2003 Act? c (iii) Whether capping of trading margins could be done by the CERC ("Central Commission'') by making a Regulation in that regard under Section 178 of the 2003 Act? DFACTS:

5. In this batch of civil appeals, appellants had challenged the vires of the Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, 2006 as null and void before the Appellate Tribunal for Electricity and had prayed for E quashing of the said Regulations. The Tribunal, however, dismissed the appeals holding that its jurisdiction was restricted by the limits imposed by the parent Statute, i.e., the Electricity Act, 2003. By the impugned judgment, the Tribunal held that the appropriate course of action for the appellants is to proceed F by way of judicial review under the Constitution. 6. In view of the importance of the question, the matter was referred by a three-Judge Bench of this Court to the Constitution Bench. While making reference to the Constitution Bench, the G question formulated was - "whether the Tribunal has jurisdiction to decide the question as to the validity of the Regulations framed by the Central Commission?" Basically, the matters involve interpretation of Sections 111 and 121 of the 2003 Act. H 620 SUPREME COURT REPORTS [2010] 3 S.C.R. I A 7.

We also quote hereinbelow the impugned Notification c dated 23.1.2006 fixing trading margin for inter-State trading of Electricity, which reads as follows: "CENTRAL ELECTRICITY REGULATORY COMMISSION NOTIFICATION D New Delhi, the 23rd January, 2006 No. L-7/25(5)/2003-CERC.- Whereas the Central Electricity Regulatory Commission is of the opinion that it is necessary to fix trading margin for inter-state trading of electricity. E Now, therefore, in exercise of powers conferred under Section 178 of the Electricity Act, 2003 (36 of 2003), and all other powers enabling it in this behalf, and after pervious publication, the Central Electricity Regulatory F Commission hereby makes the following regulations, namely:- 1. Short title and commencement.-(1) These regulations may be called the Central Electricity Regulatory Commission (Fixation of Trading Margin) Regulations, G 2006.

Trading Margin.- The licensee shall not charge the trading margin exceeding four (4.0) paise/kWh on the electricity traded, including all charges, except the charges for scheduled energy, open access and transmission losses. 8 Explanation:- The charges for the open access include the transmission charge, operating charge and the application fee. A.K. SACHAN, Secy." c SCOPE AND ANALYSIS OF THE 2003 ACT 9. The 2003 Act is enacted as an exhaustive Code on all matters concerning electricity. It provides for "unbundling" of SEBs into separate utilities for generation, transmission and D distribution. It repeals the Indian Electricity Act, 1910, the Electricity (Supply) Act, 1948 and the Electricity Regulatory Commissions Act, 1998. The 2003 Act, in furtherance of the policy envisaged under the Electricity Regulatory Commissions Act, 1998 ("1998 Act"), mandated the establishment of an E independent and transparent regulatory mechanism, and has entrusted wide ranging responsibilities with the Regulatory Commissions. While the 1998 Act provided for independent regulation in the area of tariff determination; the 2003 Act has distanced the Government from all forms of regulation, namely, F licensing, tariff regulation, specifying Grid Code, facilitating competition through open access, etc.

10. Section 3 of the 2003 Act requires the Central Government, in consultation with the State Governments and G the Authority, to prepare National Electricity Policy as well as Tariff Policy for development of the power system based on optimum utilization of resources. The Central and the State Governments are also vested with rule-making powers under Sections 176 and 180 respectively, while the "Authority" has H been defined under Section 2(6) as regulation-making power PTC INDIA LTD. v. CENTRAL ELECTRICITY 653 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

under Section 177. On the other hand, the Regulatory A Commissions are vested with the power to frame policy, in the form of regulations, under various provisions of the 2003 Act. However, the Regulatory Commissions are empowered to frame policy, in the form of regulations, as guided by the general policy framed by the Central Government. They are to be guided B by the National Electricity Policy, the Tariff Policy as well as the National Electricity Plan in terms of Sections 79(4) and 86(4) after the 2003 Act (see also Section 66). In this connection, it may also be noted that the Central Government has also, in exercise of its powers under Section 3 of the 2003 Act, notified c the Tariff Policy with effect from 6.1.2006. One of the primary objectives of the Tariff Policy is to ensure availability of electricity to consumers at reasonable and competitive rates. The Tariff Policy tries to balance the interests of consumers and the need for investments while prescribing the rate of return. It 0 also tries to promote training in electricity for making the markets competitive. Under the Tariff Policy, there is a mandate given to the Regulatory Commissions, namely, to monitor the trading transactions continuously and ensure that the electricity traders do not indulge in profiteering in cases of market failure. E The Tariff Policy directs the Regulatory Commissions to fix the trading margin in a manner which would reduce the costs of electricity to the consumers and, at the same time, they should endeavour to meet the requirement for investments.

11. An "electricity trader'' is defined under Section 2(26) F to mean a person who has been given a licence to undertake trading in electricity under Section 12. Section 2(32) defines a "grid" as the high voltage backbone system of inter-connected transmission lines, sub-station and generating plants. Under Section 2(33), a "Grid Code" is defined as a code specified G by the Central Commission under Section 79(1)(h), while under Section 2(34), ·"Grid Standards" are those specified by the Central Authority under Section 73(d). Under Section 2(47), "open access" is defined to mean the non-discriminatory provision for access to the transmission lines or distribution H 654 SUPREME COURT REPORTS [2010] 3 S.C.R. A system or associated facilities given to any licensee or consumer or a person engaged in generation of electricity in accordance with the regulations specified. Section 2(62) defines the term "specified" to mean specified by regulatioris made by the Appropriate Commission or the Authority under B the 2003 Act. Under Section 2(71 ), the word "trading" is defined to mean purchase of electricity for resale thereof.

12. Under the 2003 Act, power generation has been de-licensed and captive generation is freely permitted, subject to approval as indicated in Sections 7, 8 and 9 of the Act. C However, under Section 12, a licence has been provided as a pre-condition for engaging in transmission or distribution or trading of electricity. Therefore, licensees are granted by the Appropriate Commission under Section 14 of the Act on applications made under Section 15. Section 16 provides D power to the Appropriate Commission to specify· any general or specific conditions which shall apply either to a licensee or to a class of licensees. Under Section 18, the Appropriate Commission is also vested with the power to amend the licence as well as to revoke it in certain stipulated circumstances, if E public interest so requires (see Section 19). Under Section 23, the Appropriate Commission has the power to issue directions to licensees to regulate supply, distribution, consumption or use of electricity, if the Appropriate Commission is of the opinion that it is necessary or expedient so to do for maintaining the F efficient supply and for securing the equitable distribution of electricity and promoting competition.

13. One of the most important features of the 2003 Act is the introduction of open access under Section 42 of the Act. G Under the open access regime, distribution companies and eligible consumers have the freedom to buy electricity directly from generating comp~nies or trading licensees of their choice and correspondingly the generating companies have the freedom to sell. H 14. Section 52 of tt1e 2003 Act deals with trading of PTC INDIA LTD. v. CENTRAL ELECTRICITY 655 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] electricity activity. Under Section 52(1 ), the Appropriate A Commission may specify the technical requirement, capital adequacy requirement and credit worthiness for being an electricity trader. Under Section 52(2), every trader is required to discharge its duties, in relation to supply and trading in electricity, as may be specified by the Appropriate B Commission. 15. The standards of performance of licensee(s) may be specified by the Appropriate Commission under Section 57 of the Act. c

16. The 2003 Act contains separate provisions for the performance of the dual functions by the Commission. Section 61 is the enabling provision for framing of regulations by the Central Commission; the determination of terms and conditions of tariff has been left to the domain of the Regulatory D Commissions under Section 61 of the Act whereas actual tariff determination by the Regulatory Commissions is covered by Section 62 of the Act. This aspect is very important for deciding the present case. Specifying the terms and conditions for determination of tariff is an exercise which is different and E distinct from actual tariff determination in accordance with the provisions of the Act for supply of electricity by a generating company to a distribution licensee or for transmission of electricity or for wheeling of electricity or for retail sale of e~~~ F

17. The term "tariff' is not defined in the 2003 Act. The term "tariff' includes within its ambit not only the fixation of rates but also the rules and regulations relating to it. If one reads Section 61 with Section 62 of the 2003 Act, it becomes clear that the Appropriate Commission shall determine the actual tariff in G accordance with the provisions of the Act, including the terms and conditions which may be specified by the Appropriate Commission under Section 61 of the said Act. Under the 2003 Act, if one reads Section 62 with Section 64, it becomes clear that although tariff fixation like price fixation is legislative in H 656 SUPREME COURT REPORTS [2010] 3 S.C.R. A character, the same under the Act is made appealable vide Section 111. These provisions, namely, Sections 61, 62 and 64 indicate the dual nature of functions performed by the Regulatory Commissions, viz, decision-making and specifying terms and conditions for tariff determination. B 18. Section 66 confers substantial powers on the Appropriate Commission to develop the relevant market in accordance with the principles of competition, fair participation as well as protection of consumers' interests.

C 19. Under Sections 111(1) and 111(6) respectively, the Tribunal has appellate and revisional powers. In addition, there are powers given to the Tribunal under Section 121 of the 2003 Act to issue orders, instructions or directions, as it may deem fit, to the Appropriate Commission for the performance of D statutory functions under the 2003 Act.

20. The 2003 Act contemplates three kinds of delegated legislation. Firstly, under Section 176, the Central Government is empowered to make rules to carry out the provisions of the E Act. Correspondingly, the State Governments are also given powers under Section 180 to make rules. Secondly, under Section 177, the Central Authority is also empowered to make regulations consistent with the Act and the rules to carry out the provisions of the Act. Thirdly, under Section 178, the Central Commission can make regulations consistent with the Act and F the rules to carry out the provisions of the Act. SERCs have a corresponding power under Section 181. The rules and regulations have to be placed before Parliament and the State Legislatures, as the case may be, under Section 179 and 182. The Parliament has the power to modify the rules/ regulations. G This power is not conferred upon the State Legislatures. A holistic reading of the 2003 Act leads to the conclusion that regulations can be made as long as two conditions are satisfied, namely, that they are consistent with the Act and that they are made for carrying out the provisions of the Act. H PTC INDIA LTD. v. CENTRAL ELECTRICITY 657 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] SUBMISSIONS: A On behalf of M/s Tata Power Trading Co. Ltd.:

21. On the scheme of the 2003 Act it was submitted by Shri Harish N. Salve, learned senior counsel, that, under the 8said Act the Central Commission and SERCs have to frame regulations as well as pass statutory orders. The Act uses the expression "fixed" in Sections 8, 19, 45 & 79; it uses the expression "determined" in the proviso to Section 9(2), Sections 20, 42, 47, 57, 61 and 67(2) and the word "specified" (i.e. by way of regulations) in Sections 13, 14, 15, 16, 17, 18(2), 28(4), C 34, 36, 38, 41, 42, 45, 51, 52, 53, 57, 61 and 67(2) of the 2003 Act. Under the 2003 Act, according to the learned counsel, there are a series of provisions which expressly require the Commission to frame regulations on specific aspects.

According to learned counsel, each of the said three D expressions have to be interpreted by the terms and in the context of the scheme of the 2003 Act and not by a priori notions of administrative law. For example, Section 61 posits the framing of regulations by the Commission, which will subject to the provisions of the 2003 Act, specify the terms and E conditions for the determination of tariff. It is possible that such regulations may be licensee-specific or generic. At the same time, under Section 62 read with Section 64 refers to determination of tariff in accordance with the provisions of the Act for supply of electricity by Gencoms, transmission of F electricity, wheeling and trading of electricity. Applying the Cynamide principle [1987(2)SCC720] of administrative law, such tariff Order would be characterized as delegated legislation yet under Section 111 of the 2003 Act it is made appealable to the Appellate Tribunal. According to the learned G counsel, "price fixation" is ordinarily "legislative" and not "adjudicatory" in character and yet under the 2003 Act tariff fixation is by Order and subject to appeal under Section 111. According to the learned counsel, use of different expressions in the Act implies different meanings. For example, in Section H 658 SUPREME COURT REPORTS [2010] 3 S.C.R.

A 79 the expressions used are "regulate", "determine", "adjudicate", "specify" and "fix". Where the function of the Commission under Sections 79 and 86 require framing of regulations, the Act has used the expression "specified" as defined. Therefore, according to the learned counsel, the word B "fix" in Section 79(1 )U) must mean to pass an appropriate order fixing trading margin which is further qualified by the Act saying "if considered necessary". In this connection, learned counsel further submitted that fixing trading margin is same as price fixation and as such margin must be fixed by an Order and not c by way of regulation. Hence, according to the learned counsel, regulations cannot be framed under Section 79(1)0) and under Section 86(1 )ti) of the 2003 Act.

22. On the interpretation of Sections 178(1) and 181(1) of the 2003 Act, learned counsel submitted that where rule making D powers are enumerated and there is a general delegation of power to make rules to carry out the provisions of the 2003 Act, the enumeration does not detract from the generality of the power conferred is the principle which has to be read in the context of the scheme of the 2003 Act. In this connection it was E submitted that under the Act the power to frame subordinate legislation to carry out the provisions of the Act are contained in Sections 176 and 180 on Central and State Governments; in Sections 178 and 181 where power to frame regulations is conferred on Regulatory Commissions and Section 177 where F the power to frame regulations is conferred on CEA. Hence, when the Central Government invokes the rule making power under Section 176(1), it cannot make rules to determine tariff since that can be done only by the appropriate Commission by virtue of Section 61 read with Section 178(2)(s). A perusal G of the scheme of the 2003 Act suggests that each and every provision of the Act where framing of regulations is contemplated has a counter-part in one of the clauses as set out in Section 178(2). In any event, according to the learned counsel, where the Act requires the discharge of a function by H a specific order, then a regulation cannot be framed to achieve PTC INDIA LTD. v. CENTRAL ELECTRICITY 659 REGULATORY CbMM. THR. SECRY. [S.H. KAPADIA, J.]

that very purpose merely because there is a power to frame A regulations. Therefore, according to the learned counsel, trading margin can be fixed only by an order under Section 79(1)0) and 86(1)0) and not by regulations.

23. On the powers of the Appellate Tribunal under Sections 8 111 and 121 of the 2003 Act, learned counsel urged, that, the said Tribunal was established as an expert second tier regulatory authority to review the actions of the Regulatory Commissions, including regulations framed by first tier regulatory bodies even in the absence of Section 121 of the 2003 Act. In this connection, learned counsel further submitted C that the powers envisaged under Section 121 are distinct from the appellate and revisional powers under Section 111 (3) and under Section 111 (6). A plain reading of Section 121 establishes that the Tribunal has the power to issue orders, instructions and directions to guide the Commission in the due D performance of its statutory function; that the said power to issue instructions, orders and directions would include the power to frame or modify the regulations made by the first tier regulatory authority, particularly in cases where the Tribunal is satisfied that the regulation framed is either not consistent with the provisions E of the Act or does not result in due performance of the duty or functions entrusted to the Commission under the 2003 Act. In the light of the provisions of Sections 111 and 121 of the 2003 Act, learned counsel urged, that, even in an appeal under Section 111 if the question of validity of delegated legislation F arises, the tribunal can consider the vires and ignore a Rule which is ultra-vires the rule-making power. The fact that there is no power in the tribunal to annul the regulation cannot deny the power to statutory tribunal to ignore ultra vires subordinate legislation. Lastly, there is no need to read down Section 121 G on a priori notion of classical administrative law that vires of the rules can only be challenged in the judicial review proceedings before a constitutional court.

H 660 SUPREME COURT REPORTS [2010] 3 S.C.R. A On behalf of PTC India Ltd.

24. Shri Vikas Singh, learned senior counsel, submitted that fixation of trading margins under normal business conditions is intrinsically contradictory and harmful to power market functioning. In this connection, it was submitted that8 capping of trading margin does not in any manner whatsoever control the selling price of electricity sold to Discerns. Such capping of trading margin results in relegating the electricity traders to mere commission agents. The role of electricity C traders is to play a dynamic role of bringing in new products in the market which is beneficial to the consumers as well as Gencoms. However, the entire object of having electricity traders stand defeated by impugned capping of trading margins. According to the learned counsel, traders in electricity bring depth to the electricity markets. They make value D additions and therefore interventions in trading by regulations should not be contrary to the letter and spirit of the Act [See Section 66]. According to the learned counsel, severe regulatory intervention like imposition of margin in a voluntary market should be resorted to only in cases of market failure. E According to the learned counsel, on the basis of statistical data, the trading margin is not a return guaranteed to a trader and that the actual margin which the trader is getting is lower than the prescribed cap. According to the learned counsel, none of the above facts have been appreciated by the Central F Commission in capping the margin as not to exceed 4.0 paise per kWh on the electricity traded.

25. On the question of law, learned counsel submitted that the right to appeal under Section 111 in respect of adjudicatory/ G administrative order cannot be defeated by colouring the decision as a regulation. In this connection learned counsel submitted that the rules/regulations framed by the executive under an Act are the law whereas regulations made by the statutory authority itself is not the regulation under which it functions, but the regulation making itself is its function. In the H PTC INDIA LTD. v. CENTRAL ELECTRICITY 661 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] former case, it is possible to argue that the Authority which is A the creature of the Statute cannot question the vires of the statute, in the latter case, the Authority is not the creature of the Regulation framed by itself, hence the sanctity given to the former is far greater than the sanctity to the latter. B

26. According to the learned counsel, that, the right to appeal is a substantive right and the same cannot be taken away by a device, i.e., by framing a regulation instead of simply passing an order as to denude the Appellant of its right of Appeal. In this connection, learned counsel urged that the Appellate Tribunal can hear the appeal against the regulation C being the function of the Commission and can examine the sanctity of the regulation if the same is framed beyond the power of the commission to do so. In other words, if the Commission is entitled to adjudicate upon a matter, it does not have the authority under the Act to give its decision the colour of a D regulation so as to denude the Tribunal of its authority under Section 111. According to the learned counsel, since the impugned regulation relegates the trading licensee to a commission agent the same is ultra vires Section 66 of the 2003 M. E 27. According to the learned counsel, under Section 79 the Commission is authorized only to fix the trading margin and since the impugned regulations are purportedly made under Section 79 the said regulations are beyond the powers of the F Central Commission and are, thus, ultra vires the 2003 Act. 28. Lastly, learned counsel for PTC adopted all the arguments of Shri Harish N. Salve, learned counsel for M/s. Tata Power Trading Company Ltd. G

29. Shri Narasimha, learned counsel and Others broadly adopted the above arguments advanced on behalf of Mis. Tata Power Trading Company and PTC India Ltd., hence, the same need not be reproduced. H 662 SUPREME COURT REPORTS [2010) 3 S.C.R. A On behalf of CERC 30. After taking us through the provisions of the 2003 Act, the National and the Tariff Policies, learned Solicitor General of India submitted that the 2003 Act contemplates three kinds of delegated legislation:8 (i) Under Section 176, the Central Government is empowered to make rules for carrying out the provisions of the Act. A corresponding power is given to the State Governments under Section 180. c (ii) Under Section 177, the CEA is empowered to make regulations consistent with the Act and the rules made under Section 176. (iii) Under Section 178, the Central Commission may D make regulations consistent with the Act and the rules generally to carry out the provisions of the Act. The corresponding power under Section 181 is conferred on SERCs.

E 31. The rules and the regulations have to be placed before the Parliament and the State Legislatures, as the case may be, under Sections 179 and 182 respectively. According to the learned counsel, even if the Rules have been laid before the Parliament and even if there is a resolution of the Parliament F approving them, the validity of the Rules has to be declared by the Court as ultra vires the Act and invalid. According to the learned counsel, there is no power conferred upon the Appellate Tribunal under Section 111 to declare the regulations framed by the Central Commission as null and void. According to the G learned counsel, Tribunals are creatures of the statute. They have no inherent power that exists in civil courts. Any power exercisable by the Tribunal has to be located in the statute under which it is formed. There is no authority for the proposition that under the Indian law, a statutory tribunal has H the jurisdiction to deal with the validity of subordinate legislation PTC INDIA LTD. v. CENTRAL ELECTRICITY 663 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] and pronounce it as ultra vires. Of course,· according to the A learned counsel, it is open to the Parliament to e)cpressly give to a Tribunal the power to consider the validity o~ $ubordinate . . legislation. However, such conferment has to be. express and unambiguous, which is not there in this case. B

32. According to the learned counsel, the mere fact that Section 79(1)0) uses the word "fix" and the mere fact that the other provisions .use the word "specify" does npt lead tq the conclusion that the Central Commission could not have iss\Jed the Trading Margin Regulations 2006 as contended by the appellants herein. The learned counsel further urged that the C general power to frame regulations is not limited or controlled by enumeration of topics on which regulations may be framed. In.this connection, it was submitted that a holist\c reading of the Act leads to the conclusion that regulations can be made as long as they are consistent with the Act and that they are D made for carrying out the provisions of the Act. The Act recognizes the need to regulate trading in electri~ity [See Sections 52(2), 53(1)(a), 57, 60, 178(2)(d), (o), (p) and (y)].

33. Learned counsel further submitted that for the reasons E mentioned herein there is no case made out by the Appellants to lift the veil over a fake regulation. The Central Commission had to initiate proceedings against 14 traders for non-compliance with licence conditions. Some traders were operating on high margins. Trading margin being the F component of the final price paid by the consumers required regulation to protect the consumers. Competition among traders to capture the surplus power for sale resulted in rising prices. Even with a trading margin of 4 paise/unit, traders can make handsome profits. For the above reasons, Commission G thought it fit to make the impugned Regulations. It was further contended that the doctrine of colourable exercise of power was not applicable to decide the validity of subordinate legislation. 34. Learned counsel lastly submitted that the power of judicial review cannot be located in Section 121 of the Act. The H 664 SUPREME COURT REPORTS [2010] 3 S.C.R.

A power under Section 121 is different from the power under Section 111. According to the learned counsel, Section 121 empowers the tribunal to act only when the Commission is guilty of inaction in carrying out its statutory functions. The power to annul a legislative act cannot be read into Section 121. Even B the High Court cannot direct the Legislature to enact a law and, therefore, such power cannot be read into Section 121. In order to entertain a challenge, directly or collaterally, the tribunal must have jurisdiction which must be conferred by the statute anq since in the instant case tribunal is not vested with su9h a c jurisdiction, it is not open to the Appellants to place reliance on some of the English Judgments. Thus, the Appellate Tribunal is not qualified to go behind a regulation as framed by CERC and to examine whether it acted within the bounds of the statute while framing the regulation. D DETERMINATIONS:

35. On the above submissions, one of the questions which arises for determination is - whether trading margin fixation (including capping) under the 2003 Act can only be done by E an Order under Section 79(1)0) and not by Regulations under Section 178? According to the appellant(s) it can only be done by an Order under Section 79(1)0), particularly when under Section 178(2) power to make regulations is co-relatable to the functions ascribed to each Authority under the said 2003 Act. F 36. In every case one needs to examine the statutory context to determine whether a court or a tribunal hearing a case has jurisdiction to rule on a defence based upon arguments of invalidity of subordinate legislation or administrative act under it. There are situations in which · G Parliament may legislate to preclude such challenges in the interest of pFOmoting certainty about the legitimacy of, administrative acts on which the public may have to rely. 37. On the above analysis of various sections of the 2003 H Act, we find that the decision-making and regulation-making PTC INDIA LTD. v. CENTRAL ELECTRICITY 665 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

functions are both assigned to CERC. Law comes into A existence not only through legislation but also by regulation and litigation. Laws from all three sources are binding. According to Professor Wade', "between legislative and administrative functions we have regulatory functions". A statutory instrument, such as a rule or regulation, emanates from the exercise of B delegated legislative power which is a part of administrative process resembling enactment of law by the legislature whereas a quasi-judicial order comes from adjudication which is also part of administrative process resembling a judicial decision by a court of law. [See Shri Sitaram Sugar Co. Ltd. c v. Union of India and Ors. reported in (1990) 3 SCC 223).

38. Applying the above test, price fixation exercise is really legislative in character, unless by the terms of a particular statute it is made quasi-judicial as in the case of Tariff fixation under Section 62 made appealable under Section 111 of the D 2003 Act, though Section 61 is an enabling provision for the framing of regulations by CERC. If one takes "Tariff' as a subject-matter, one finds that under Part VII of the 2003 Act . actual determination/ fixation of tariff is done by the Appropriate Commission under Section 62 whereas Section 61 is the E enabling provision for framing of regulations containing generic propositions in accordance with which the Appropriate Commission has to fix the tariff. This basic scheme equally applies to subject-matter "trading margin" in a different statutory context as will be demonstrated by discussion hereinbelow. In F the case of Mis Narinder Chand Hem Raj and Ors. v. Lt. Governor, Administrator, Union Territory, Himachal Pradesh and Ors. reported in (1971) 2 SCC 747, this Court has held that power to tax is a legislative power which can be exercised by the legislature directly or subject to certain conditions. The G legislature can delegate that power to some other Authority. But the exercise of that power, whether by the legislature or by the delegate will be an exercise of legislative power. The fact tb~t the power can be delegated will not make it an administrative 1power or adjudicatory power. In the said judgment, it has been H

666 SUPREME COURT REPORTS [2010] 3 S.C.R.

A further held that no court can direct a subordinate legislative body or the legislature to enact a law or to modify the existing law and if Courts cannot so direct, much less the Tribunal, unless power to annul or modify is expressly given to it. In the case of Indian Express Newspapers (Bombay) Pvt. Ltd. and B Ors. v. Union of India and Ors. reported in (1985) 1 SCC 641, this Court held that subordinate legislation is outside the purview of administrative action, i.e., on the grounds of violation of rules of natural justice or that it has not taken into account relevant circumstances or that it is not reasonable. However, a c distiAction must be made between delegation of legislative function and investment of discretion to exercise a particular discretionary power by a statute. In the latter case, the impugned exercise of discretion may be considered on all grounds on which administrative action may be questioned such as non-application of mind, taking irrelevant matters into0 consideration etc. The subordinate legislation is, however, beyond the reach of administrative law. Thus, delegated legislation - otherwise known as secondary, subordinate or administrative legislation - is enacted by the administrative branch of the government, usually under the powers conferred E upon it by the primary legislation. Delegated legislation takes a number of forms and a number of terms - rules, regulations, by-laws etc; however, instead of the said labels what is· of significance is the provisions in the primary legislation which, in the first place, confer the power to enact administrative F legislation.· Such provisions are also called as "enabling provisions". They demarcate the extent of the administrator's legislative power, the decision-making power and the policy making power. However, any legislation enacted outside the terms of the enabling provision will be vulnerable_ to judicial G review and ultra vires.

39. Applying the above mentioned tests to the scheme of 2003 Act, we find that under the Act, the Central Commission is a decision-making as well as regulation-making authority, H simultaneously. Section 79 delineates the functions of the PTC INDIA LTD. v. CENTRAL ELECTRICITY 667 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] Central Commission broadly into two categories - mandatory A functions and advisory functions. Tariff regulation, licensing (including inter-State trading licensing), adjudication upon disputes involving generating companies or transmission licensees fall under the head "mandatory functions" whereas advising Central Government on formulation of National B Electricity Policy and tariff policy would fall under the head "advisory functions". In this sense, the Central Commission is the decision-making authority. Such decision-making under Section 79(1) is not dependant upon making of regulations under Section 178 by the Central Commission. Therefore, c functions of Central Commission enumerated in Section 79 are separate and distinct from function of Central Commission under Section 178. The former is administrative/adjudicatory function whereas the latter is legislative. ·

40. As stated above, the 2003 Act has been enacted in D furtherance of the policy envisaged under the Electricity Regulatory Commissions Act, 1998 as it mandates establishment of an independent and transparent Regulatory Commission entrusted with wide ranging responsibilities and objectives inter alia including protection of the consumers of E electricity. Accordingly, the Central Commission is set up under Section 76(1) to exercise the powers conferred on, and in discharge of the functions assigned to, it under the Act. On reading Sections 76(1) and 79(1) one finds that Central Commission is empowered to take measures/steps in F discharge of the functions enumerated in Section 79( 1) like to regulate the tariff of generating companies, to regulate the inter-state transmission of electricity, to determine tariff for inter-state transmission of electricity, to issue licenses, to adjudicate upon disputes, to levy fees, to specify the Grid Code, to fix the G trading margin in inter-State trading of electricity, if considered necessary, etc .. These measures, which the Central Commission is empowered to take, have got to be in conformity with the regulations under Section 178, wherever such regulations are applicable. Measures under Section H 668 SUPREME COURT REPORTS (2010] 3 S.C.R.

A 79(1 ), therefore, have got to be in conformity with the regulations under Seqtion 178. To regulate is an exercise which is different from making of the regulations. However, making of a regulation under Section ·178 is not a pre-condition to the Central Commission taking any steps/measures under Sectiorr B 79(1). As stated, if there is a regulation, then the measure under Section 79(1) has to be in conformity with such regulation under Section 178. This principle flows from various judgments of this Court which we have discussed hereinafter. For example, under Section 79(1)(g) the Central Commission is required to levy c fees for the purpose of the 2003 Act. An Order imposing regulatory fees could be passed even in the absence of a· regulation under Section 178. If the levy is unreasonable, it could be the subject matter of challenge before the Appellate Authority under Section 111 as the levy is imposed by an Order/ decision making process. Making of a regulation under Section0 178 is not a pre-condition to passing of an Order levying a regulatory fee under Section 79(1)(g). However, if there is a regulation under Section 178 in that regard then the Order levying fees under Section 79(1)(g) has to be in consonance with such regulation. Similarly, while exercising the power to E frame the terms and conditions for determination of tariff under Section 178, the Commission has to be guided by the factors specified in Section 61. It is open to the Central Commission to specify terms and conditions for determination of tariff even in the absence of the regulations under Section 178. However, F if a regulation is made under Section 178, then, in that event, framing of terms and conditions for determination of tariff under Section 61 has to be in consonance with the regulation under Section 178. One must keep in mind the dichotomy between the power to make a regulation under Section 178 on one hand G and the various enumerated areas in Section 79(1) in which the Central Commission is mandated to take such measures as it deems fit to fulfil the objects of the 2003 Act. Applying this test to the-,,resent controversy, it becomes clear that one such area enumerated in Section 79(1) refers to fixation of trading H margin. Making of a regulation in that regard il? not a pre-PTC INDIA LTD. v. CENTRAL ELECTRICITY 669

REGULATORY COMM. THR. SECRY. (S.H. KAPADIA, J.] condition to the Central Commission exercising its powers to A fix a trading margin under Section 79(1 )0), however, if the Central Commission in an appropriate case, as is the case herein, makes a regulation fixing a cap on the trading margin under Section 178 then whatever measures a Central Commission takes under Section 79(1 )(j) has to be in B conformity with Section 178. One must understand the reason why a regulation has been made in the matter of capping the trading margin under Section 178 of the Act. Instead of fixing a trading margin (including capping) on a case to case basis, the Central Commission thought it fit to make a regulation which C has a general application to the entire trading activity which has been recognized, for the first time, under the 2003 Act. Further, it is impprtant to bear in mind that making of a regulation under Section 178 became necessary because a regulation made under Section 178 has the effect of interfering and overriding 0the existing contractual relationship between the regulated entities. A regulation under Section 178 is in the nature of a subordinate Legislation. Such subordinate Legislation can even override the existing contracts including Power Purchase Agreements which have got to be aligned with the regulations under Section 178 and which could not have been done across E the board by an Order of the Central Commission under Section 79(1)0).

41. To elucidate, we may refer to the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) F Regulations, 2004. The said Regulations have been made under Section 178 of the 2003 Act. Regulation 15 deals with various components of tariff. It includes Advance Against Depreciation ("AAD" for short). Regulations 21 (1 )(ii) and 38(ii) deal with computation of depreciation including AAD. Recently, G this concept of AAD came for consideration before this Court in the case of National Hydroelectric Power Corporation Ltd. v. CIT reported in 2010 (1) SCALE 5. AAD was suggested by the Central Commission as part of the tariff in order to overcome the cash flow problems faced by Central Power H 670 SUPREMli COURT REPORTS [2010] 3 S.C.R.

A Sector Utilities for meeting loan repayment obligations. The important point to be noted is that although under Section 61 of the 2003 Act the Central Commission is empowered to specify AAD as a condition for determination of the tariff, the Central Commission in its wisdom thought it fit to bring in the concept of AAD by enacting a regulation under Section 178 8 giving the benefit of AAD across the board to all Central Power Sector Utilities. In other words, instead of giving the benefit of AAD on a case to case basis under Section 61, the Central Commission decided to make a specifii; regulation giving C benefit of AAD across the board to all Central Power Sector Utilities. There is one more reason why a regulation under Section 178 with regard to AAD had to be made by CERC. Under the 2003 Act, the Central Commission is empowered under Section 61 to include depreciation as an item in the computation of tariff. However, if the rate of depreciation D envisaged by the Central Commission under the 2003 Act is different from the rate(s) of depreciation prescribed under Schedule XIV of the Companies Act, 1956 then such differential rate can be prescribed under the 2003 Act only by way of regulation under Section 178 of the 2003 Act which is in the E nature of subordinate legislation. It is important to note that the Companies Act, 1956 constitutes a law applicable to companies. It prescribes the format of Balance Sheet in Schedule VI. It prescribes the requirements as to Profit and Loss account vide Part II of Schedule VI. It also prescribes the F rates of depreciation vide Schedule XIV. If a different rate is required to be prescribed under the 2003 Act, then it could be done only by way of subordinate legislation, which is "' contemplated by Regulations framed under Section 178 of the 2003 Act. Similarly, profits earned by a trading company are G not only required to be presented in the manner indicated under the Companies Act but it is also required to be computed under the Income-tax Act, 1961. If such profits/income of a trading company is required to be capped under the 2003 Act, it can .. only be done by a subordinate legislation made under Section H · 178 of the 2003 Act. Accrual of income/profit under the PTC INDIA LTD. v. CENTRAL ELECTRICITY 671

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] Companies Act, 1956 or the Income-tax Act, 1961 can only be A curbed by a regulation made under the authority of subordinate legislation or primary legislation. This is exactly what is sought to be achieved by the impugned Regulation.

42.-0ne more-citation may be noticed. Reserve Bank of B India is a Regulator under the RBI Act, 1934 ("1934 Act"). Under the 1934 Act; RBI is empo\vered not only to regulate banks but also financial institutions, NBFCs etc .. Chapter Ill B of the 1934 Act deals with provisions relating to financial institutiohs and NBFCs receiving deposits from the public. Under Section 45JA C of the 1934 Act, RBI is given the power to determine policy and issue directions to NBFCs and financial. institutions in public · interest or in order to regulate the financial system of the country. Section 45JA, however, is confined to Chapter Ill B. However, under Section 58, which falls in Chapter IV, dealing with general provisions, the Board of Directors of RBI are given the power D to make regulations consistent with the 1934 Act to provide for all matters for which provision is necessary. The principle of "generality versus enumeration" is also applicable to Section 58 of RBI Regulations because under Section 58(2) there is a list of topics enumerated on which regulations could be made. E In other words, Section 58 (1), (2) of the 1934 Act is similar to Section 178 (1), (2) of the 2003 Act. Recently, before the Division Bench of this Court, the question arose, inter alia, as to the' accounting treatment to be given by NBFCs accepting deposits from the public in the context of provision to be made F for Non Performing Assets ("NPAs"). An Order was passed by RBI under Section 45JA of the 1934 Act stating that although provision for doubtful debts is required to be reduced from the assets' side of the balance sheet under the provisions of the Companies Act, 1956, for proper disclosure under the 1934 G Act, such a provision should be shown in the balance sheet specifically on the liabilities' side. It is interesting to note that the Order was passed under Section 45JA which, as stated above, is part of Chapter Ill B of the 1934 Act, which chapter expressly deals with provisions relating to NBFCs. There was H

672 SUPREME COURT REPORTS [2010] 3 S.C.R A no regulation enacted under Section 58 on the topic, namely, NPAs. The point to be noted is, that there could be an Order/ decision of a regulator under the Act even in the absence of regulations. RBI like CERC is a regulator under the 1934 Act. Under Section 45JA it is empowered to issue directions in B contradistinction to its powers to enact regulations. under Section 58 of the 1934 Act. Giving directions under Section 45JA need not be preceded by regulations made under Section 58, however, if in a given case, RBI/Board would have enacted a regulation on making of provision for NPAs under Section 58 c then the Order of RBI under Section 45JA of the 1934 Act was required to be in conformity with the said regulations. (See the judgment of this Court in the case of Mis Southern Technologies Ltd. v. Joint Commissioner of Income Tax, Coimbatore reported in 2010 (1) SCALE 329.)

D 43. The above two citations have been given by us only to demonstrate that under the 2003 Act, applying the test of "general application", a Regulation stands on a higher pedestal vis-a-vis an Order (decision) of CERC in the sense that an Order has to be in conformity with the regulations. However, that E would not mean that a regulation is a pre-condition to the order (decision). Therefore, we are not in agreement with the contention of the appellant(s) that under the 2003 Act, power to make regulations under Section 178 has to be correlated to the functions ascribed to each authority under the 2003 Act and F that CERC can enact regulations only on topics enumerated in Section 178(2). In our view, apart from Section 178(1) which deals with "generality" even under Section 178(2)(ze) CERC could enact a regulation on any topic which may not fall in the enumerated list provided such powedalls within the scope of G 2003 Act. Trading is an activity recognized under the said 2003 Act. While deciding the nature of an Order (decision) vis-a-vis a Regulation under the Act, one needs to apply the test of general application. On the making of the impugned Regulations 2006, even the existing Power Purchase H Agreements ("PPA") had to be modified and aligned with the PTC INDIA LTD. v. CEN'rRAL ELECTRICITY 673 ' . 1 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.)

said Regulations. In other words, the impugned Regulation A makes an inroad into even the existing contracts. This itself indicates the width of the power conferred on CERC under Section 178 of the 2003 Act. All contracts coming into existence after making of the impugned Regulations 2006 have also to factor in the capping of the trading margin. This itself indicates B that the impugned Regulations are in the nature of subordinate legislation. Such regulatory intervention into the existing contracts across-the-board could have been done only by making Regulations under Section 178 and not by passing an Order under S~ction 79(1 )0) of the 2003 Act. Therefore, in our c view, if we keep the above discussion in mind, it becomes clear that the word "order'' in Section 111 of the 2003 Act cannot include the impugned Regulations 2006 made under Section 178 .of the 2003 Act. D 44. We may usefully refer to some decisions relevant in the context.

45. In the case of City Board, Mussoorie v. State Electricity Board and Ors., reported in AIR (58) 1971 Allahabad 219, the matter arose under Electricity (Supply) Act, E 1948 ("1948 Act"). Under that Act, Grid Tariff had to be fixed from time to time under Section 46(1) "in accordance with any regulations made in that behalf'. Under Section 79 of the 1948 Act, the Board was also given the power to make regulations not inconsistent with the Act and the Rules made thereunder F to provide for all or any of the matters enumerated therein. It was argued on behalf of the appellant that the regulations must exist before a Grid Tariff can be fixed. This argument was rejected by the High Court which held that there was nothing in the 1948 Act to suggest that existence of a regulation was a G pre-condition to the determination of a grid tariff. It was held that under Section 46 of 1948 Act, the Board was given a wide discretion to frame the grid tariff depending upon various factors mentioned in the Act. According to the High Court, Section 46 of the Act was a standalone provision, therefore, the grid tariff H 674 SUPREME COURT REPORTS (2010] 3 S.C.R.

A could be fixed even in the absence of the regulations provided such fixation is not inconsistent with the 1948 Act. However, it was further observed that if the Board had made regulations under Section 79 then order framing the grid tariff under Section 46(1) had to conform to such regulations. This view stood B affirmed by this Court in the case of U.P. State Electricity Board, Lucknow v. City Board, Mussoorie, reported in (1985) 2 sec 16.

46. A similar question arose for determination by this Court C in the case of Mis Jagdamba Paper Industries (Pvt.) Ltd. and Ors. v. Haryana State Electricity Board and Ors., reported in AIR 1983 SC 1296. In that case, enhancement in the security for meters and for payment of energy bills came to be challenged. It was argued on behalf of the appellants that the Board had not framed any Regulations under Section 79 of the D 1948 Act for such enhancement. According to the appellants, the supply of electricity was controlled under an agreement between the Board and the appellants and therefore unilateral escalation of security charges by passing of an Order under Section 49 would be contrary to any acceptable notion of E contract. It was contended that under Section 49(1) of the 1948 Act, the Board was conferred with statutory powers to determine the conditions on the basis of which supply had to be made. Therefore, without determining the conditions under Section 49(1), it was not open to the Board to unilaterally enhance the F security charges contrary to the existing contract between the Board and the consumers. This argument was rejected by this Court which held that what apply to the tariff fixation. would equally apply to the security. Section 49(1) of the 1948 Act clearly indicated that the Board may supply electricity to any G person upon such terms and conditions as the Board thinks fit. It was held that since the contract between the consumer and the Board contemplated enhancement of security charges as a condition of supply of electricity, it was not open to the appellants to say that such enhancement cannot take place H without regulations being framed under Section 79. This PTC INDIA LTD. v. CENTRAL ELECTRICITY 675

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] judgment is important from another angle also. It indicates that A regulations under Section 79 of 1948 Act were to be in the nature of subordinate legislation, therefore, all contracts had to be in terms of such regulations. In the present case also, if one examines the terms and conditions of the licences, power to fix trading margin is expressly contemplated by such terms. The B said judgment further held that the Board is a statutory authority and has to act within the framework of the 1948 Act. If the act of the Board is not in consonance or in breach of some statutory provisions of law, rule or regulation, it is always open to challenge in a petition under Section 226 of the Constitution. c

47. In the case of Kera/a State Electricity-Board v. S.N. Govinda Prabhu and Bros. and Ors., reported in (1986) 4 sec 198, the dispute was confined to the question concerning increase in the electricity tariff by the Board under the 1948 Act. 0The principal ground of challenge was that the Board had acted outside its statutory authority by formulating a price structure intended to yield sufficient revenue to offset not only the actual expenditure as contemplated by Section 59 of the 1948 Act but also expenditure not covered by that section. At this stage, we may point out that, in all these cases, the Supreme Court has E considered tariff fixation, price fixation, security charges fixation at par. In that case, one of the submissions which found favour. with the High Court, which accepted the submissions of the consumer, while striking down the impugned notification, was that in the absence of specification by the State Government, F it was not open to the Board to adjust the tariffs. What was found by the Supreme Court was that although the expenditure did not fall strictly within Section 59 of the 1948 Act, the actual expenditure stood incurred to avoid the loss. Therefore, the Supreme Court gave a schematic interpretation to the 1948 Act G and it held that the State Electricity Board was obliged to carry on its business economically and efficiently and consequently such charges were admissible even though they did not fall strictly within the ambit of Section 59. On the question as to absence of specification by the State Government, this Court H

676 SUPREME COURT REPORTS [2010] 3 S.C.R. A . further held that the omission of the rule-making authority to · frame rules cannot takeaway the right to factor in such expenses in the revised tariff structure. This judgment is one more case which indicates that making of regulations is not a pre-condition to the tariff fixation or price fixation or security B charges fixation.

48. In the case of Hindustan Zinc Ltd. etc. v. Andhra Pradesh State Electricity Board and Ors. reported in (1991) 3 SCC 299, the main attack was to the upward revision of the C tariffs for HT consumers in the writ petition before the High Court, inter alia, on the ground that the Board cannot generate a surplus in excess of the surplus specified under Section 59 of the 1948 Act. Section 59 of that Act gave power to the Board to lay down general principles for Board's finance. It was also contended that the tariff revision was made without prior D consultation with the State Electricity Consultative Council as required by Section 16(5) of the 1948 Act. It was held by this Court that even in the absence of general principles being specified under Section 59 of that Act, it was open to the Board to generate a surplus in order to carry on the business in a more E efficient and economic manner. Following the judgment in the case of S.N. Govinda Prabhu (supra), it was held that even in the absence of prior consuitation with the State Electricity Consultative Council as required by Section 16(5), it was open to the Board which was vested with the power of tariff fixation F to make an upward revision of tariff. In other words, specification by. making rules or regulations was not a pre-condition for upward revision of tariff. It was observed that, if in a given case, it is found that such upward revision was arbitrary, then under the judicial review jurisdiction it was open to the G courts to strike down such upward revision as arbitrary under Article 14. It was further observed that the "laying down procedure" before the Legislature was meant to effectively control the exercise of the delegated power of the Board, however, such laying down procedure will not make the H impugned regulation immune from judicial review. (Also see the PTC INDIA LTD. v. CENTRAL ELECTRICITY 677

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] judgment of this Court in Indian Express Newspapers A (Bombay) Pvt. Ltd. and Ors. v. Union of India and Ors. reported in (1985) 1 sec 641. !)aragraphs 75 to 79). 49. On the question of "generality versus enumeration" principle, it was further held in the case of Hindustan Zinc Ltd. B (supra) that under Section 49(1) of the 1948 Act a general power was given to the Board to supply electricity to any person not being a licensee upon such terms and conditions as the Board thinks fit and the Board may for the purposes of such supply frame uniform tariffs under Section 49(2). The Board was required to fix uniform tariffs after taking into account certain C enumerated factors. It was held that the power of fixation of tariffs in the Board ordinarily had to be done in the light of specified factors, however, such enumerated factors in Section 49(2) did not prevent the Board from fixing uniform tariffs on factors other than those enumerated in Section 49(2) as long D as they were relevant and in consonance with the Act. To the same effect is the judgment of this Court in Shri Sitaram Sugar . Co. Ltd. (supra). In that judgment also this Court held that the enumerated factors/topics in a provision do not mean that the authority cannot take any other matter into consideration which E may- be relevant. The words in the enumerated provision are not a fetter; they are not words of limitation, but they are words for general guidance.

50. One more s..;pect needs to be mentioned. The F judgment of this Court in Shri Sitaram Sugar Co. Ltd. (supra) has laid down various tests to distinguish legislative from ·administrative functions. It further held that price fixation is a legislative function unless the statute provides otherwise. It also laid down the scope of judicial review in such cases. G 51. Applying the above judgments to the present case, it is clear that fixation of the trading margin in the inter-State trading of electricity can be done by making of regulations under Section 178 of 2003 Act. Power to fix the trading margin H 678 SUPREME COURT REPORTS [2010] 3 S.C.R. A under Section 178 is, therefore, a legislative power and the Notification issued under that section amounts to a piece of subordinate legislation, which has a general application in the sense that even existing contracts are required to be modified in terms of the impugned· Regulations. These Regulations make B an inroad into contractual relationships between the parties. Such is the scope and effect of the impugned Regulations which could not have taken place by an Order fixing the trading margin under Section 79(1)U). Consequently, the impugned Regulations cannot fall within the ambit of the word "Order" in c Section 111 of the 2003 Act.

52. Before concluding on this topic, we still need to examine the scope of Section 121 of the 2003 Act. In this case, appellant(s) have relied on Section 121 to locate the power of judicial review in the Tribunal. For that purpose, we must notice · D the salient features of Section 121. Under Section 121, there must be a failure by a Commission to perform its statutory function in which event the Tribunal is given authority to issue orders, instructions or directions to the Commission to perform its statutory functions. Under Section 121 the Commission has E to be heard before such orders, instructions or directions can be issued. 53. The main issue which we have to decide is the nature of the power under Section 121. lri the case of Mis Raman and F Raman Ltd. v. State of Madras and Ors. reported in AIR 1959 SC 694, Section 43A of Motor Vehicles Act, 1939, ("1939 Act"), as amended by Madras Act 20 of 1948, came for consideration before the Supreme Court. Section 43A conferred power on the State Government to issue "orders" and G "directions", as it may consider necessary in respect of any matter relating to road transport to the State Transport Authority or a Regional Transport Authority. The meaning of the words "orders" and "directions" came for interpretation before the Supreme Court in the said case. It was held, on examination H of the Scheme of the Act, that Section 43A was placed by the PTC INDIA LTD. v. CENTRAL ELECTRICITY 679

REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

legislature before the sections conferring quasi-judicial powers A on Tribunals which clearly indicated that the authority conferred under Section 43A was confined to administrative functions of the Government and the Tribunals rather than to their judicial functions. It was further held that the legislature had used two words in the section: (i) orders; and (ii) directions. This Court s further noticed that under the 1939 Act there was a separate Chapter which dealt with making of "rules" which indicated that the words "orders" and "directions" in Section 43A were meant to clothe the Government-with the authority to issue directions of administrative character. It was held that the source of power c did not affect the character of acts done in exercise of that power. Whether it is a law or an administrative direction depends upon the character or nature of the orders or directions authorized to be issued in exercise of the power conferred. It was, therefore, held that the words "orders" and "directions" 0were not laws. They were binding only on the Authorities under the Act. Such orders and directions were not required to be published. They were not kept for scrutiny by legislature. It was further held that such orders and directions did not override the discretionary powers conferred on an authority under Section E60 of the 1939 Act. It was observed that non compliance of such orders, instructions and directions may result in taking disciplinary action but they cannot affect a finding given by the quasi-judicial authority nor can they impinge upon the rules enacted by the rule-making authority. It was held that such Forders and directions would cover only an administrative field of the officers concerned and therefore such orders and directions do not regulate the rights of the parties. Such orders and directions cannot add to the considerations/topics prescribed under Section 47 of the 1939 Act on the basis of which an adjudicatir:ig authority is empowered to issue or refuse G permits, as the case may be.

54. Applying the tests laid down in the above judgment to the present case, we are of the view that, the words "orders", "instructions" or "directions" in Section 121 do not confer power H 680 SUPREME COURT REPORTS [2010] 3 S.C.R.

A of judicial review in the Tribunal. It is not possible to lay down any exhaustive list of cases in which there is failure in performance of statutory functions by Appropriate Commission. However, by way of illustrations, we may state that, under Section 79(1)(h) CERC is required to specify Grid Code having B regard to Grid Standards. Section 79 comes in Part X. Section 79 deals with functions of CERC. The word "grid" is defined in Section 2(32) to mean high voltage backbone system of interconnected transmission lines, sub-station and generating plants. Basically, a grid is a network. Section 2(33) defines "grid c code" to mean a code specified by CERC under Section 79(1 )(h). Section 2(34) defines "grid standards" to mean standards specified under Section 73(d) by the Authority. Grid Code is a set of rules which governs the maintenance of the network. This maintenance is vital. In summer months grids tend to trip. In the absence of the making of the Grid Code in0 accordance with the Grid Standards, it is open to the Tribunal to direct CERC to perform its statutory functions of specifying the Grid Code having regard to the Grid Standards prescribed by the Authority under Section 73. One can multiply these illustrations which exercise we do not wish to undertake. Suffice E it to state that, in the light of our analysis of the 2003 Act, hereinabove, the words orders, instructions or directions in Section 121 of the 2003 Act cannot confer power of judicial review under Section 121 to the Tribunal, which, therefore, cannot go into the validity of the impugned Regulations 2006, F as rightly held in the impugned judgment.

55. One of the contentions raised by Shri Shanti Bhushan, learned senior counsel appearing on behalf of Calcutta Electricity Supply Company Ltd. needs to be considered. It was G contended on behalf of CESC Ltd. that under Section 111 of the 2003 Act, an appeal lies only against an Order by the Appropriate Commission and not against Regulations framed by CERC under Section 178 of the 2003 Act. It was contended that Regulations under Section 178 are framed in exercise of H delegated power in which there was an element of legislative . i PTC INDIA LTD. v. CENTRAL ELECTRICITY 681 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.]

function. That, the Regulations framed by CERC are required A to be laid before the Parliament under Section 179 of the 2003 Act. The said Regulations could be modified by the two Houses of the Parliament. In the circumstances, it was, therefore, contended that neither Section 111 nor Section 121 would be deemed to have conferred any power on the Appellate Tribunal B for Electricity to supervise or sit in judgment over the Regulations. To this extent, learned counsel supported the contentions of the learned Solicitor General, appearing on behalf of CERC (respondent no.1). Further, an interesting argument was advanced by the learned counsel, namely, that, c Section 121 of the 2003 Act has not yet been brought into force. In this connection, reference was made to Section 1(3) of the 2003 Act as well as to the notification dated 10.6.2003 issued under Section 1(3) of the 2003 Act by which the Central Government had fixed 10.6.2003 as the date on which Sections 0 1 to 120 and Sections 122 to 185 were brought into force, however, Section 121 was not brought into force till Notification dated 27 .1.2004, which brought into force Electricity (Amendment) Act 2003 (No.57 of 2003) came to be issued. According to the learned counsel, Section 4 of the Electricity E (Amendment) Act, 2003 (No.57 of 2003) which was brought into force on 27.1.2004 merely provided for substitution of the original Section 121 with new Section 121, without issuance of a further notification under Section 1(3) of the original Electricity Act, 2003. According to the learned counsel, there Fis a differencs between substituting a dormant Section iri an Act and in bringing a substituted section into force which has not been done in this case and, therefore, Section 121, although being part of the statute, is not brought into force, till today. To answer the above contention, we need to quote Section 1(3) and also Section 121 of the original Electricity Act, 2003 which G was not brought into force though, as stated above, Sections 1 to 120 and Sections 122 to 185 were brought into force vide notification dated 10.6.2003:

H 682 SUPREME COURT REPORTS [2010] 3 S.C.R. A "Section 1. Short title, extent and commencement. - (3) It shall come into force on such date as the Central Government may, by notification, appoint: Provided that different dates may be appointed for B different provisions of this Act and any reference in any such provision to the commencement of this Act shall be construed as a reference to the coming into force of that provision." "Section 121. Power of Chairperson of Appellatec Tribunal.- The Chairperson of the Appellate Tribunal shall exercise general power of superintendence and control over the appropriate Commission." 56. We also quote hereinbelow Sections 1 and 4 of the D Electricity (Amendment) Act, 2003 (No.57 of 2003) which was brought into force on 27.1.2004: "Section 1. (2) It shall come into force on such date as the Central Government may, by notification in the Official E Gazette, appoint. Section 4. For Section 121 of the principal Act, the following Section shall be substituted, namely:-"121. Power of Appellate Tribunal F The Appellate Tribunal may, after hearing the Appropriate Commission or other interested party, if any, from time to time, issue such orders, instructions or directions as it may deem fit, to any Appropriate Commission for the G performance of its statutory functions under this Act."

57. As stated above, the Electricity (Amendment) Act, 2003 (No.57 of 2003) was brought into force by Notification dated 27.1.2004 which is reproduced hereinbelow: H PTC INDIA LTD. v. CENTRAL ELECTRICITY 683 . REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] "MINISTRY OF POWER A Notification New Delhi, the 27th January, 2004 S.0.119(E). In exercise of the powers conferred by sub-section (2) of Section 1 of the Electricity (Amendment) 8 Act, 2003 (57 of 2003), the Central Government hereby appoints the 27th January, 2004, as the date on which the provisions of the said Act shall come into force. [F. No.23/23/2004-R&R] AJAY SHANKAR, Jt. Secy." C

58. In our view, there is no merit in the above contention advanced on behalf of CESC Ltd. At the outset, we may state that material brought on record indicates that Section 121 of the original Electricity Act, 2003, quoted hereinabove, was D never brought into force because some MPs expressed the concern that the power, under that section, conferred upon the Chairperson of the Appellate Tribunal, could lead to excessive centralization of power and interference with the day-to-day activities of the Commission by the Chairperson of the Tribunal. E Therefore, Section 121 was amended by Electricity (Amendment) Act, 2003 (No.57 of 2003) which is also quoted hereinabove and which amendment Act came into force from 27.1.2004. In our view, by necessary implication of the coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force, hence, F there is no requirement for a further notification under Section 1(3), particularly when Section 121 in its amended form has come into force w.e.f. 27.1.2004. In this connection, it may be seen that Section 121 of the original Act stood substituted by Amendment Act No.57 of 2003. Substitution of a provision G results in repeal of the earlier provision and its replacement by the new provision. Substitution is a combination of repeal and fresh enactment. [See: Principles of Statutory Interpretation by G.P. Singh, 11th Edn., p. 638]. Section 121 of the original Electricity Act, 2003 was never brought into force. It was H

684 SUPREME COURT REPORTS [2010] 3 S.C.R. A substituted by new Section 121 by Amendment Act No.57 of 2003 which was brought into force by a notification dated 27.1.2004. Substitution, as stated above, results in repeal of the old provision and replacement by a new provision. Applying these tests to the facts of the present case, we find that the B Electricity (Amendment) Act, 2003 (No.57 of 2003) was brought into force by notification dated 27.1.2004. That, notification was issued under Section 1 (2) of the Electricity (Amendment) Act, 2003 (No.57 of 2003). If one reads Section 1(2) of Electricity (Amendment) Act, 2003 (No.57 of 200:.=,) with Notification dated c 27.1.2004 issued under Section 1 (2) of the amended Act, 2003, it becomes clear that on coming into force of the Electricity (Amendment) Act, 2003 (No.57 of 2003) all provisions amended by it also came into force. Hence, there was no requirement for a further notification under Section 1 (3), consequently, Section 121 in its amended form came into force0 with effect from 27.1.2004. 59. Summary of Our Findings: (i) In the hierarchy of regulatory powers and functions E under the 2003 Act, Section 178, which deals with making of regulations by the Central Commission, under the authority of subordinate legislation, is wider than Section 79( 1) of the 2003 Act, which enumerates the regulatory functions of the Central Commission, in specified areas, to be dischargedF by Orders (decisions).

(ii) A regulation under Section 178, as a part of regulatory framework, intervenes and even overrides the existing contracts between the G regulated entities inasmuch as it casts a statutory obligation on the regulated entities· to align their existing and future contracts with the said regulations. H (iii) A regulation under Section 178 is made under the PTC INDIA LTD. v. CENTRAL ELECTRICITY 685 REGULATORY COMM. THR. SECRY. [S.H. KAPADIA, J.] authority of delegated legislation and consequently A its validity can be tested only in judicial review proceedings before the courts and not by way of appeal before the Appellate Tribunal for Electricity under Section 111 of the said Act. B (iv) Section 121 of the 2003 Act does not confer power of judicial review on the Appellate Tribunal. The words "orders", "instructions" or "directions" in Section 121 do not confer power of judicial review in the Appellate Tribunal for Electricity. In this C judgment, we do not wish to analyse the English authorities as we find from those authorities that in certain cases in England the power of judicial review is expressly conferred on the Tribunals constituted under the Act. In the present 2003 Act, the power of judicial review of the validity of the D Regulations made under Section 178 is not conferred on the Appellate Tribunal for Electricity.

(v) If a dispute arises in adjudication on interpretation of a regulation made under Section 178, an appeal E would certainly lie before the Appellate Tribunal under Section 111, however, no appeal to the Appellate Tribunal shall lie on the validity of a regulation made under Section 178. (vi) Applying the principle of "generality versus F enumeration", it would be open to the Central Commission to make a regulation on any residuary item under Section 178( 1) read with Section 178(2)(ze). Accordingly, we hold that the CERC was empowered to cap th~ trading margin under G the authority of delegated legislation under Section 178 vide the impugned notification dated 23.1.2006. (vii) Section 121, as amended by Electricity H "l ~.~·~\". 686 _ SUPREME COURT REPORTS [2010] 3 S.C.R. A (Amendment) Act 57 of 2003, came into force with effect from 27.1.2004. Consequently, there is no merit in the contention advanced that the said section is not yet been brought into force. B Conclusion: 60. For the aforesaid reasons, we answer the question raised in the reference as follows: The Appellate Tribunal for Electricity has no jurisdiction to c decide the validity of the Regulations framed by the Central Electricity Regulatory Commission under Section 178 of the Electricity Act, 2003. The validity of the Regulations may, however, be challenged by seeking judicial review under Article 226 of the Constitution of India.

D Our summary of findings and answer to the reference are with reference to the provisions of the Electricity Act, 2003. They shall not be construed as a general principle of law to be applied to Appellate Tribunals vis-a-vis Regulatory Commissions under other enactments. In particular, we make E it clear that the decision may not be taken as expression of any view in regard to the powers of Securities Appellate Tribunal vis-a-vis Securities and Exchange Board of India under the Securities and Exchange Board of India Act, 1992 or with reference to the Telecom Disputes Settlements and Appellate F Tribunal vis-a-vis Telecom Regulatory Authority of India under the Telecom Regulatory Authority of India Act, 1997. 61. In view of our findings, we dismiss these appeals as having no merit with no order as to costs, G K.K.T. Appeals dismissed.
