1. Part IV-A of the Constitution of India containing fundamental duties as set out in Article 51A was incorporated in the Constitution by the 42nd Amendment Act with effect from 3rd January 1977. Clause (g) 2622 [2025] 5 S.C.R. Supreme Court Reports of Article 51A provides that it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures. This Court in several decisions has held that the right to live in a pollution free atmosphere is a part of the fundamental right guaranteed under Article 21 of the Constitution of India. 2. The world changed rapidly after World War II. From the late 1960s and early 1970s, slowly there was a realisation about the drastic consequences of the destruction of environment and pollution of various kinds. In June 1972, at Stockholm, the United Nations Conference on Human Environment was held. In the said conference, several decisions were taken by the world community to protect the environment. 3. In our country, it took fourteen years thereafter for the legislature to come out with a law for protection and improvement of the environment. The Environment (Protection) Act, 1986 (for short, ‘the 1986 Act’) was brought into force with effect from 19th November 1986. As can be noticed from several orders of this Court and the High Courts, the progress of implementation of the 1986 Act has been very slow.

4. The 1970s and 1980s saw growth of industrialisation in our country. The activities such as mining, gas exploration, thermal power plants, petroleum refining industries, various other industries, building and construction projects, such as, highways started growing. 5. Again, it took twenty years after the 1986 Act came into force to exercise the power under sub-section (1) and clause (v) of sub-section (2) of Section 3 of the 1986 Act read with clause (d) of sub-rule (3) of Rule 5 of the Environment (Protection) Rules, 1986 (for short, ‘1986 Rules’) for coming out with the Environment Impact Assessment Notification, 2006 (for short, ‘the EIA notification’). The EIA notification was issued on 14th September 2006. It provided that the projects or activities mentioned in clause (2) thereof shall require prior Environmental Clearance (for short, ‘the EC’) from the concerned regulatory authority. The concerned regulatory authority in the Central Government is the Ministry of Environment Forests and Climate Change (for short, ‘the MoEFCC’) for matters falling under Category ‘A’ in the Schedule, and at the State level, the State Environment Impact Assessment Authority (for short, ‘the SEIAA’) for [2025] 5 S.C.R. 2623 Vanashakti v. Union of India the matters falling in Category ‘B’. In the Schedule, Categories ‘A’ and ‘B’ were incorporated setting out industries and other development work. The entire controversy in this group of petitions is about ex post facto grant of EC.

6. On 14th March 2017, a notification was issued by the MoEFCC. The said notification is hereafter referred to as ‘the 2017 notification’. The said notification was made applicable to the projects or activities that have started the work on site, expanded the production beyond the limit of the EC, or changed the production mix without obtaining EC. The 2017 notification provided that in case of such works, ex post facto EC can be granted. It provided that the projects or activities which are in violation of the EIA notification as on 14th March 2017 were eligible to apply under the 2017 notification for ex post facto EC within a period of six months from 14th March 2017. 7. The National Green Tribunal (for short, ‘the NGT’) vide order dated 24th May 2021 directed the MoEFCC to prepare a Standard Operating Procedure (for short, ‘the SOP’) for grant of EC in the cases of violation so as to address the gap in the binding law and practice being currently followed. In purported compliance with the said direction, Office Memorandum dated 7th July 2021 (for short, ‘the 2021 OM’) was issued.

8. In the meanwhile, the 2017 notification was challenged by way of a writ petition before the High Court of Madras in the case of Puducherry Environment Protection Association v. Union of India1, which was decided by order dated 13th October 2017. During the course of hearing of the case before the Madras High Court, when it was pointed out that the outer limit for making applications for grant of ex post facto EC have been repeatedly extended, the Union of India gave a categorical undertaking that the 2017 notification was only a one-time measure. By recording the said submission made on behalf of the Union of India that the 2017 notification was certainly and clearly only a one time measure, the High Court disposed of the petition. Later on, by order dated 14th March 2018 passed by the High Court of Madras in another case, the time period under the 2017 notification for submission of proposals by project proponents was extended by a further period of thirty days. 1 2017 SCC OnLine Mad 7056 2624 [2025] 5 S.C.R. Supreme Court Reports

9. In Writ Petition (C) No.1394 of 2023, the first prayer is for quashing the 2021 OM on the ground that it was arbitrary, illegal and ultra vires the provisions of the 1986 Act. The second prayer is for issuing a writ of mandamus directing the MoEFCC and SEIAA/SEACs not to process and entertain any application for ex-post facto EC after 13th May 2018. As stated earlier, the time granted under the 2017 notification to apply was lastly extended till 13th April 2018. 10. In Writ Petition (C) No.118 of 2019, the challenge is to the 2017 notification issued by the MoEFCC. A prayer was made seeking directions to the respondents to produce a list of real estate projects and project proponents who have undertaken real estate development projects without obtaining EC under the 2006 notification. 11. In Writ Petition (C) No.115 of 2024, the challenge is to the 2017 notification and the 2021 OM. A prayer for writ of prohibition is made for restraining the MoEFCC from issuing any notification or office memorandum permitting ex-post facto EC.

12. The High Court of Madras by judgment and order dated 30th August 2024 quashed the 2021 OM and another OM dated 19th February 2021. The challenge in Civil Appeal No.381-382 of 2025 is to this decision of the High Court of Madras. In the judgment and order dated 30th August 2024, the Madras High Court declared that its order will operate only prospectively and applications under consideration will remain unaffected. The challenge in this appeal is only to the extent of giving prospective effect to the impugned judgment. THE EIA NOTIFICATION 13. Firstly, we come to the EIA notification. It has been issued in exercise of powers under sub-Section (1) and clause (v) of sub-Section (2) of Section 3 of the 1986 Act read with clause (d) of sub-Rule (3) of Rule 5 of the 1986 Rules. Section 3 of the 1986 Act reads thus: “3. Power of Central Government to take measures to protect and improve environment.—(1) Subject to the provisions of this Act, the Central Government shall have the power to take all such measures as it deems necessary or expedient for the purpose of protecting and improving the quality of the environment and [2025] 5 S.C.R. 2625 Vanashakti v. Union of India preventing, controlling and abating environmental pollution. (2) In particular, and without prejudice to the generality of the provisions of sub-section (1), such measures may include measures with respect to all or any of the following matters, namely:—

(i) co-ordination of actions by the State Governments, officers and other authorities— (a) under this Act, or the rules made thereunder; or (b) under any other law for the time being in force which is relatable to the objects of this Act; (ii) planning and execution of a nation-wide programme for the prevention, control and abatement of environmental pollution; (iii) laying down standards for the quality of environment in its various aspects; (iv) laying down standards for emission or discharge of environmental pollutants from various sources whatsoever: Provided that different standards for emission or discharge may be laid down under this clause from different sources having regard to the quality or composition of the emission or discharge of environmental pollutants from such sources; (v) restriction of areas in which any industries, operations or processes or class of industries, operations or processes shall not be carried out or shall be carried out subject to certain safeguards; (vi) laying down procedures and safeguards for the prevention of accidents which may cause environmental pollution and remedial measures for such accidents; (vii) laying down procedures and safeguards for the handling of hazardous substances; (viii) examination of such manufacturing processes, materials and substances as are likely to cause environmental pollution; 2626 [2025] 5 S.C.R. Supreme Court Reports

(ix) carrying out and sponsoring investigations and research relating to problems of environmental pollution; (x) inspection of any premises, plant, equipment, machinery, manufacturing or other processes, materials or substances and giving, by order, of such directions to such authorities, officers or persons as it may consider necessary to take steps for the prevention, control and abatement of environmental pollution; (xi) establishment or recognition of environmental laboratories and institutes to carry out the functions entrusted to such environmental laboratories and institutes under this Act; (xii) collection and dissemination of information in respect of matters relating to environmental pollution; (xiii) preparation of manuals, codes or guides relating to the prevention control and abatement of environmental pollution; (xiv) such other matters as the Central Government deems necessary or expedient for the purpose of securing the effective implementation of the provisions of this Act.

(3) The Central Government may, if it considers it necessary or expedient so to do for the purposes of this Act, by order, published in the Official Gazette, constitute an authority or authorities by such name or names as may be specified in the order for the purpose of exercising and performing such of the powers and functions (including the power to issue directions under Section 5) of the Central Government under this Act and for taking measures with respect to such of the matters referred to in sub-section (2) as may be mentioned in the order and subject to the supervision and control of the Central Government and the provisions of such order, such authority or authorities may exercise the powers or perform the functions or take the measures so mentioned in the order as if such authority or authorities had been empowered by this Act to exercise those powers or perform those functions or take such measures.” (emphasis added) [2025] 5 S.C.R. 2627 Vanashakti v. Union of India

13.1 Sub-section (1) of Section 3 sums up the very object of the 1986 Act. Therefore, the EIA notification has been issued not only for the purposes of protecting and improving the quality of the environment but also for preventing and abating environmental pollution. Sub-section (1) of Section 3 confers general power of taking measures on the Central Government. Sub-section (2) confers specific power for taking measures in the matters set out in clauses (i) to (ix) thereof. Clause (v) of sub-section (2) of Section 3 empowers the Central Government to take measures for putting restrictions of areas in which any industries, operations or processes shall not be carried out or shall be carried out subject to safeguards. 14. Rule 5 of the 1986 Rules reads thus: “5. Prohibition and restriction on the location of industries and the carrying on of processes and operations in different areas.—(1) The Central Government may take into consideration the following factors while prohibiting or restricting the location of industries and carrying on of processes and operations in different areas: (i) Standards for quality of environment in its various aspects laid down for an area. (ii) The maximum allowable limits of concentration of various environmental pollutants (including noise) for an area. (iii) The likely emission or discharge of environmental pollutants from an industry, process or operation proposed to be prohibited or restricted.

(iv) The topographic and climatic features of an area. (v) The biological diversity of the area which, in the opinion of the Central Government needs to be preserved. (vi) Environmentally compatible land use. (vii) Net adverse environmental impact likely to be caused by an industry, process or operation proposed to be prohibited or restricted. 2628 [2025] 5 S.C.R. Supreme Court Reports (viii) Proximity to a protected area under the Ancient Monuments and Archaeological Sites and Remains Act, 1958 or a sanctuary, National Park, game reserve or closed area notified as such under the Wild Life (Protection) Act, 1972 or places protected under any treaty, agreement or convention with any other country or countries or in pursuance of any decision made in any international conference, association or other body. (ix) Proximity to human settlements. (x) Any other factor as may be considered by the Central Government to be relevant to the protection of the environment in an area. (2) While prohibiting or restricting the location of industries and carrying on of processes and operations in an area, the Central Government shall follow the procedure hereinafter laid down.

(3) (a) Whenever it appears to the Central Government that it is expedient to impose prohibition or restrictions on the location of an industry or the carrying on of processes and operations in an area, it may, by notification in the Official Gazette and in such other manner as the Central Government may deem necessary from time to time, give notice of its intention to do so. (b) Every notification under clause (a) shall give a brief description of the area, the industries, operations, processes in that area about which such notification pertains and also specify the reasons for the imposition of prohibition or restrictions on the location of the industries and carrying on of processes or operations in that area. (c) Any person interested in filing an objection against the imposition of prohibition or restrictions on carrying on of processes or operations as notified under clause (a) may do so in writing to the Central Government within sixty days from the date of publication in the notification in the Official Gazette. (d) The Central Government shall within a period of one hundred and twenty days from the date of publication [2025] 5 S.C.R. 2629 Vanashakti v. Union of India

of the notification in the Official Gazette consider all the objections received against such notification and may [within [seven hundred and twenty-five days [,and in respect of the States of Assam, Meghalaya, Arunachal Pradesh, Mizoram, Manipur, Nagaland, Tripura, Sikkim and Jammu and Kashmir in exceptional circumstance and for sufficient reasons within a further period of one hundred and eighty days,]] from such date of publication] impose prohibition or restrictions on location of such industries and the carrying on of any process or operation in an area: [Provided that on account of COVID-19 pandemic, for the purpose of this clause, the period of validity of the notification expiring in the financial year 2020-2021 and 2021-2022 shall be extended up to [30th June, 2022] or six months from the end of the month when the relevant notification would have expired without any extension, whichever is later.] [(4) Notwithstanding anything contained in sub-rule (3), whenever it appears to the Central Government that it is in public interest to do so, it may dispense with the requirement of notice under clause (a) of sub-rule (3).]”

14.1 For issuing the EIA notification, power has been exercised under clause (d) of sub-rule (3) of Rule 5 which empowers the Central Government to impose prohibition or restrictions on location of such industries and the carrying on any process or operation in an area. There is a power to impose complete prohibition on carrying on any process or operation in an area. Clause (2) of the EIA notification reads thus: “2. Requirements of prior Environmental Clearance (EC):- The following projects or activities shall require prior environmental clearance from the concerned regulatory authority, which shall hereinafter referred to be as the Central Government in the Ministry of Environment and Forests for matters falling under Category ‘A’ in the Schedule and at State level the State Environment Impact Assessment Authority (SEIAA) for matters falling under Category ‘B’ in the said Schedule and at District level, 2630 [2025] 5 S.C.R. Supreme Court Reports the District Environment Impact Assessment Authority (DEIAA) for matters falling under Category ‘B2’ for mining minerals in the said Schedule, before any construction work, or preparation of land by the project management except for securing the land, is started on the project or activity: (i) All new projects or activities listed in the Schedule to this notification;

(ii) Expansion, modernization or any change in the product mix or raw material mix in existing projects or activities listed in the Schedule to this notification with addition of capacity beyond the limits specified for the concerned sector in the said Schedule, subject to conditions and procedure provided in the sub-paragraph (ii) of paragraph 7.” 14.2 Therefore, without prior EC, construction of new projects or activities, expansion or modernisation of existing projects or activities listed in the Schedule entailing capacity addition with change in process or technology, cannot be undertaken. Entire procedure for grant of prior EC is laid down in the EIA notification. LEGALITY OF THE 2017 NOTIFICATION 15. The 2017 notification refers to the OMs dated 12th December 2012 and 27th June 2013 by which a process was sought to be established for grant of EC in the cases of violation of the EIA notification. It also refers to the judgment of the High Court of Jharkhand holding these two OMs as illegal. The same OMs were also quashed by the NGT as mentioned in the said notification. There are three recitals in the said notification which are relevant. Recital Nos.9 to 11 read thus:

“9. And whereas, the Ministry of Environment, Forest and Climate Change and State Environment Impact Assessment Authorities have been receiving certain proposals under the Environment Impact Assessment Notification, 2006 for grant of Terms of References and Environmental Clearance for projects which have started [2025] 5 S.C.R. 2631 Vanashakti v. Union of India the work on site, expanded the production beyond the limit of environmental clearance or changed the product mix without obtaining prior environmental clearance; 10. Whereas, the Ministry of Environment, Forest and Climate Change deems it necessary for the purpose of protecting and improving the quality of the environment and abating environmental pollution that all entities not complying with environmental regulation under Environment Impact Assessment Notification, 2006 be brought under compliance with in the environmental laws in expedient manner;

11. And whereas, the Ministry of Environment, Forest and Climate Change deems it necessary to bring such projects and activities in compliance with the environmental laws at the earliest point of time, rather than leaving them unregulated and unchecked, which will be more damaging to the environment and in furtherance of this objective, the Government of India deems it essential to establish a process for appraisal of such cases of violation for prescribing adequate environmental safeguards to entities and the process should be such that it deters violation of provisions of Environment Impact Assessment Notification, 2006 and the pecuniary benefit of violation and damage to environment is adequately compensated for;” 15.1 Thus, what was sought to be done was to protect the project proponents who committed gross illegality by commencing construction or commencing operation or process without obtaining prior EC as provided in the EIA notification. The 2017 notification was a one-time measure. Moreover, this Court in the case of Common Cause v Union of India & Ors.2, held in no uncertain terms that the concept of ex post facto or retrospective EC is completely alien to environmental jurisprudence including the EIA notification. The decision in the case of Common Cause2 was delivered on 2nd August 2 (2017) 9 SCC 499 2632 [2025] 5 S.C.R. Supreme Court Reports

2017. Notwithstanding the clear declaration of law which was made on 2nd August 2017, the Central Government did not withdraw the 2017 notification. 16. We may note here that this is not the first time that the concept of prior EC was brought into force. For this purpose, useful reference can be made to a decision of this Court in the case of Alembic Pharmaceuticals v. Rohit Prajapati3. It records that there was a notification of 27th January 1994 mandating prior EC for setting up and expansion of industrial projects falling within thirty categories. The issue before this Court was about the legality and validity of the circular dated 14th May 2002, which permitted obtaining of ex post facto EC. This Court specifically dealt with the challenge to the circular dated 14th May 2002. In paragraph 12, this Court noted the issue to be decided: “12. The issue to be adjudicated is whether in view of the requirement of a prior EC under the EIA Notification of 1994, a provision for an ex post facto EC to industrial units could be validly made by means of the Circular dated 14-5-2002.” 16.1 Thereafter, this Court considered Section 3(1) of the 1986 Act. In paragraph 21 this Court held thus:

“21. The omission in the appeal to make any attempt to sustain the Circular dated 14-5-2002 with reference to the provisions of Section 3 of the Environment (Protection) Act, 1986 is significant. For an action of the Central Government to be treated as a measure referable to Section 3 it must satisfy the statutory requirement of being necessary or expedient “for the purpose of protecting and improving the quality of the environment and preventing, controlling and abating environment pollution”. The Circular dated 14-5-2002 in fact does quite the contrary. It purported to allow an extension of time for industrial units to comply with the requirement of an EC. The EIA Notification dated 27-1-1994 mandated that an EC has to be obtained before embarking on a 3 (2020) 17 SCC 157 [2025] 5 S.C.R. 2633 Vanashakti v. Union of India new project or expanding or modernising an existing one.

The EIA Notification of 1994 has been issued under the provisions of the Environment (Protection) Act, 1986 and the Environment Protection Rules, 1986, with the object of imposing restrictions and prohibitions on setting up of new projects or expansion or modernisation of existing project. The measures are based on the precautionary principle and aim to protect the interests of the environment. The Circular dated 14-5-2002 allowed defaulting industrial units which had commenced activities without an EC to cure the default by an ex post facto clearance. Being an administrative decision, it is beyond the scope of Section 3 and cannot be said to be a measure for the purpose of protecting and improving the quality of the environment. The circular notes that there were defaulting units which had failed to comply with the requirement of obtaining an EC as mandated. The circular provided for an extension of time and inexplicably introduced the notion of an ex post facto clearance. In effect, it impacted the obligation of the industrial units to be in compliance with the law. The concept of ex post facto clearance is fundamentally at odds with the EIA Notification dated 27-1-1994. The EIA Notification of 1994 contained a stipulation that any expansion or modernisation of an activity or setting up of a new project listed in Schedule I “shall not be undertaken in any part of India unless it has been accorded environmental clearance”.

The language of the notification is as clear as it can be to indicate that the requirement is of a prior EC. A mandatory provision requires complete compliance. The words “shall not be undertaken” read in conjunction with the expression “unless” can only have one meaning : before undertaking a new project or expanding or modernising an existing one, an EC must be obtained. When the EIA Notification of 1994 mandates a prior EC, it proscribes a post activity approval or an ex post facto permission. What is sought to be achieved by the administrative Circular dated 14-5-2002 is contrary to the statutory Notification 2634 [2025] 5 S.C.R. Supreme Court Reports

dated 27-1-1994. The Circular dated 14-5-2002 does not stipulate how the detrimental effects on the environment would be taken care of if the project proponent is granted an ex post facto EC. The EIA Notification of 1994 mandates a prior environmental clearance. The circular substantially amends or alters the application of the EIA Notification of 1994. The mandate of not commencing a new project or expanding or modernising an existing one unless an environmental clearance has been obtained stands diluted and is rendered ineffective by the issuance of the administrative Circular dated 14-5-2002. This discussion leads us to the conclusion that the administrative circular is not a measure protected by Section 3. Hence there was no jurisdictional bar on NGT to enquire into its legitimacy or vires. Moreover, the administrative circular is contrary to the EIA Notification 1994 which has a statutory character. The circular is unsustainable in law.” (emphasis added) 16.2 Ultimately, in paragraph 23, this Court held thus:

The concept of an ex post facto EC is in derogation of the fundamental principles of environmental jurisprudence and is an anathema to the EIA Notification dated 27-1-1994. It is, as the judgment in Common Cause [Common Cause v. Union of India, (2017) 9 SCC 499] holds, detrimental to the environment and could lead to irreparable degradation. The reason why a retrospective EC or an ex post facto clearance is alien to environmental jurisprudence is that before the issuance of an EC, the statutory notification warrants a careful application of mind, besides a study into the likely consequences of a proposed activity on the environment. An EC can be issued only after various stages of the decision-making process have been completed. Requirements such as conducting a public hearing, screening, scoping and appraisal are components of the decision-making process which ensure that the likely impacts of the industrial activity or the expansion of an existing industrial activity [2025] 5 S.C.R. 2635 Vanashakti v. Union of India

are considered in the decision-making calculus. Allowing for an ex post facto clearance would essentially condone the operation of industrial activities without the grant of an EC. In the absence of an EC, there would be no conditions that would safeguard the environment. Moreover, if the EC was to be ultimately refused, irreparable harm would have been caused to the environment. In either view of the matter, environment law cannot countenance the notion of an ex post facto clearance. This would be contrary to both the precautionary principle as well as the need for sustainable development.” (emphasis added) 16.3 In fact, as noted in paragraph 22.1, the word ‘prior’ was not used in the EIA notification dated 27th January 1994. However, the words ‘shall not be undertaken’ were used. In the 2006 EIA notification, the word ‘prior’ appears at multiple places. 17. The issue of ex post facto EC was dealt with in the case of Common Cause2, In paragraph 108, a submission was recorded that the possibility of getting ex post facto EC was a signal to the mining leaseholders that obtaining an EC was not mandatory or that if it was not obtained, the default was retrospectively condonable. In paragraph 125, this Court held thus:

“125. We are not in agreement with the learned counsel for the mining leaseholders. There is no doubt that the grant of an EC cannot be taken as a mechanical exercise. It can only be granted after due diligence and reasonable care since damage to the environment can have a long-term impact. EIA 1994 is therefore very clear that if expansion or modernisation of any mining activity exceeds the existing pollution load, a prior EC is necessary and as already held by this Court in M.C. Mehta [M.C. Mehta v. Union of India, (2004) 12 SCC 118] even for the renewal of a mining lease where there is no expansion or modernisation of any activity, a prior EC is necessary. Such importance having been given to an EC, the grant of an ex post facto environmental clearance would be detrimental to the environment and could lead to irreparable 2636 [2025] 5 S.C.R. Supreme Court Reports degradation of the environment. The concept of an ex post facto or a retrospective EC is completely alien to environmental jurisprudence including EIA 1994 and EIA 2006. We make it clear that an EC will come into force not earlier than the date of its grant.” (emphasis added)

18. Therefore, there is already a concluded finding of this Court that the concept of ex post facto or retrospective EC is completely alien to environmental jurisprudence and the EIA notification. This view was reiterated by this Court in the case of Electrosteel Steels Ltd. v. Union of India and Ors.4,. In paragraph 72, this Court held thus: “72. There can be no doubt that the need to comply with the requirement to obtain environment clearance is non-negotiable. A project can be set up or allowed to expand subject to compliance of the requisite norms. Environmental clearance is granted on condition of the suitability of the site to set up the project from the environmental angle, and existence of necessary infrastructural facilities and equipment for compliance of environmental norms. To protect future generations, it is imperative that pollution laws be strictly enforced. Under no circumstances, can industries which pollute be allowed to operate unchecked and degrade the environment.” (emphasis added) 18.1 In this case, as well as in the case of Alembic Pharmaceuticals3, this Court exercised its jurisdiction under Article 142 of the Constitution and permitted ex post facto EC in particular cases considering the peculiar factual situation.

19. It is in this context that the legality and validity of the 2017 notification will have to be tested. Interestingly, in paragraph 10 of the notification, it is recorded that the MoEFCC deems it necessary for the purpose of protecting and improving the quality of environment and abating environmental pollution that all the entities not complying with the environmental regulation under EIA notification be brought 4 (2023) 6 SCC 615 [2025] 5 S.C.R. 2637 Vanashakti v. Union of India under compliance within the environmental laws in an expeditious manner. The object of protecting and improving the environment and preventing and abating environmental pollution was achieved by the EIA notification. The object of the 2017 notification appears to be to protect the industries and entities which violated the EIA notification. In fact, paragraph 14 of the 2017 notification is material which reads thus: “14. The projects or activities which are in violation as on date of this notification only will be eligible to apply for environmental clearance under this notification and the project proponents can apply for environmental clearance under this notification only within six months from the date of this notification.”

20. Moreover, the 2017 notification is completely in violation of the law laid down by this court in the case of Common Cause2 and Alembic Pharmaceuticals3. From the recitals of the 2017 notification, it is apparent that it was a one-time measure to protect those who were in violation as on the date of the 2017 notification. In view of the settled law, even a ‘one-time measure’ or ‘one-time relaxation’ was illegal. The 2021 OM encourages the entities who contributed to pollution by not obtaining prior EC. Whenever EC is granted, it is always conditional. Certain conditions are imposed to abate or reduce the pollution. Such one-time measures add to air and/or water pollution. Such measures infringe the right to live in a pollution free environment guaranteed by Article 21. Thus, the 2017 notification was completely illegal.

21. The Division bench of Madras High Court by judgment dated 13th October 2017, in the case of Puducherry Environment Protection Association1 dealt with the issue regarding the legality of the 2017 notification which was subject matter of challenge in a Public Interest Litigation. A very specific submission was made before the Madras High Court on behalf of the Central Government by the learned Additional Solicitor General, which is recorded in paragraph 4(i) of the judgment. Relevant portion of paragraph 4(i) reads thus: “4(i) With regard to precautionary principle, faced with the situation that ex post facto clearance and regularization dates have been repeatedly extended time and again by series of notifications, learned Additional Solicitor 2638 [2025] 5 S.C.R. Supreme Court Reports General at the bar, on instructions, submits that this impugned notification shall clearly and certainly be only a one time measure. We record this submission also. ………………………….............……………………………” (emphasis added) 21.1 This statement was treated as an undertaking of the Central Government, which is clear from paragraph 4(n) of the said judgment:

“4(n) We are convinced that paragraphs 3,4 and 5 of the impugned notification alluded to supra coupled with the two undertakings made on instructions by learned Additional Solicitor General that (a) public hearing can be read into paragraph 5 of the impugned notification and (b) this shall certainly and clearly be a one time measure, this writ petition can be closed and disposed of recording the above submissions. We do so.” (emphasis added) 21.2 It is in view of this undertaking that the High Court did not interfere. The Central Government is bound by this undertaking. It is the duty of the Central Government to comply with the undertaking in its true letter and spirit. 22. The period provided in the 2017 notification to apply for ex-post facto EC ended on 13th September 2017. In the case of Appaswamy Real Estates Limited v. Puducherry Environment Protection Association5, the request of the MoEFCC for extending the time provided in the 2017 notification was accepted. As a result, the OM dated 16th March 2018 was issued which permitted the project proponents to apply under the 2017 notification within thirty days from the date of the High Court order. What is pertinent to note is that notwithstanding the grant of extension of time to apply, there was no modification made to paragraph 14 of the 2017 notification which clarified that it is applicable only to those projects and activities 5 2018 SCC OnLine Mad 1283 [2025] 5 S.C.R. 2639 Vanashakti v. Union of India

which were in violation on the date of the said notification. Therefore, any project or activity or process which required EC under the EIA notification commenced after 14th March 2017 was not protected by the 2017 notification. 23. Apart from the fact that the very concept of grant of ex-post facto EC is illegal, it is not possible to understand why the Central Government made efforts to protect those who committed illegality by not obtaining prior EC in terms of the EIA notification. As the EIA notification was eleven years old when the 2017 notification was issued, there was no equity in favour of those who committed such gross illegality of not obtaining prior EC. The persons who acted without prior EC were not illiterate persons. They were companies, real estate developers, public sector undertakings, mining industries, etc. They were the persons who knowingly committed illegality. We, therefore, make it clear that hereafter, the Central Government shall not come out with a new version of the 2017 notification which provides for the grant of ex-post facto EC in any manner. LEGALITY AND VALIDITY OF THE 2021 OM SUBMISSIONS

24. The learned senior counsel appearing for the Petitioner submitted that post a series of judgments of this Court in Alembic3 and Common Cause2, it is not permissible to grant ex post facto EC. He further submits that the 2021 OM is in violation of the 1986 Act and the EIA notification. He submits that EC must be prior and cannot be granted ex post facto. While the 2021 OM does not expressly extend the timeline under the 2017 notification or mention ex post facto, the 2021 OM and its application has effectively allowed grant of ex post facto EC. 25. The main submission of the learned Additional Solicitor General is that the 2021 OM does not seek to grant ex-post facto EC. It is only an SOP. The learned ASG invited our attention to the contents of the SOP. Her submission is that it provides for the demolition of projects not allowable or permissible for want of EC. It also provides for the closure of projects allowable/permissible, if prior EC has not been taken as per the EIA notification. She submitted that even if EC is granted, it will be effective from the date of the issue, and therefore, it is not ex post facto. She submitted that before such EC 2640 [2025] 5 S.C.R. Supreme Court Reports

is granted, the project proponent will have to pay certain amounts as provided therein based on Polluter Pays Principle. Moreover, the project proponents will have to undertake activities relating to remedial plan and community accommodation plan. She also pointed out that the projects which are not allowable or permissible, shall be demolished. She also pointed out provisions regarding penalty, project proponents furnishing bank guarantee, etc. Thus, in short, her submission is that the object of the 2021 OM is to protect those projects and industries which could have been granted an EC under EIA notification before the date of commencement of activities, but proceeded to commence activities without EC. Her submission is that this measure has been taken to ensure that the huge spending on constructions is not lost and wasted. OUR VIEW 26. The basic submission by learned ASG is based on a premise that what is provided under the 2021 OM is not grant of ex-post facto EC. The relevant part of the 2021 OM is in paragraph 10 and 11, which read thus: “10.Standard Operating Procedure-Guiding Principles: i. Without prejudice to any other consequences, action has to be initiated under section 15 read with section 19 of The Environment (Protection) Act, 1986 against all violations. ii. Projects not allowable/permissible, for grant of EC, as per extant regulations: To be demolished.

iii. Projects allowable/permissible, if prior EC had been taken as per extant regulations: To be closed until EC is granted (if no prior EC has been taken) or to revert to permitted production level (in case prior EC has been granted). iv. Polluter pays: Violators to pay for violation period proportionate to the scale of project and extent of commercial transaction. v. Setting up a mechanism for reporting of violation to the regulatory authority(ies). [2025] 5 S.C.R. 2641 Vanashakti v. Union of India 11. SOP for dealing with the violation cases: Step 1: Closure or Revision Sl no. Status of EC Actions 1 If no prior EC has been Order to close its operation taken 2 If prior EC is available for Order to revert the activity / existing/old unit production to permissible limits. 3 If prior EC was not Restrict the activity /production required for earlier to the extent to which prior EC production level but is was not required now required Step 2: Action under Environment (Projection) Act, 1986 Action under section 15 read with section 19 of the Environment (Protection) Act, 1986 shall be initiated against the violators. Step: 3: Appraisal under EIA Notification, 2006 The permissibility of the project shall be examined from the perspective of whether such activity/project was at all eligible for the grant of prior EC. A. If not permissible:

i. The project shall be ordered for the demolition/closure after issuing show cause notice and providing an opportunity of hearing. Ex. If a red industry is functioning in a CRZ-I area which means that the activity was, in the first place, not permitted at the time of commencement of project. Therefore, the activity is not permissible and therefore it shall be closed & demolished. ii. Respective regulatory authorities shall issue directions under section 5 of the Environment (Protection) Act, 1986 for such closure & demolition of the project/activity. 2642 [2025] 5 S.C.R. Supreme Court Reports B. If permissible: i. As per extant regulations at the time of scoping, if it is viewed that the project activity is otherwise permissible, Terms of Reference (TOR) shall be issued with directions to complete the impact assessment studies & submit Environmental Impact Assessment (EIA) report & Environmental Management Plan (EMP) in a time bound manner. ii. Such cases of violation shall be subject to appropriate (a) Damage Assessment (b) Remedial Plan and (c) Community Augmentation Plan by the Central Level Sectoral Expert Appraisal Committees or State/ Union Territory Level Expert Appraisal Committees, as the case may be.

iii. The Competent Authority shall issue directions to the project proponent, under section 5 of the Environment (Protection) Act, 1986 on case to case basis mandating payment of such amount (as may be determined based on Polluter Pays principle) and undertaking activities relating to Remedial Plan and Community Augmentation Plan (to restore environmental damage caused including its social aspects). iv. Upon submission of the EIA & EMP report, the project shall be appraised by the Central Sectoral Expert Appraisal Committees or the State/Union Territory Level Expert Appraisal Committees, as the case may be, as if it was a new proposal. If, on examination of the EIA/EMP report, the project is considered permissible for operation as per extant regulations, the requisite Environmental Clearance shall be issued which shall be effective from the date of issue. v. However, during appraisal after examination if it is found that even though the project may be permissible but not environmentally sustainable in its present form/configuration/features then the project shall be [2025] 5 S.C.R. 2643 Vanashakti v. Union of India directed to be modified so that the project would be environmentally sustainable.

vi. If, however, it is not considered appropriate to issue EC, the project shall be directed to be demolished/ closed. If such proposal is a case of expansion, the project shall be directed to revert back to the extent of activity for which EC had been granted earlier or to revert back to the extent of activity for which EC was not required (as the case may be). vii. Central Sectoral Expert Appraisal Committees or the State/Union Territory Level Expert Appraisal Committees, as the case may be, may insist upon public hearing to be conducted for such categories of projects for which the EIA Notification 2006, as amended from time to time, requires the public hearing to be conducted. viii. The project proponent will be required to submit a bank guarantee equivalent to the amount of Remediation Plan and Natural & Community Resource Augmentation Plan with Central / the State Pollution Control Board (depending on whether it is appraised at Ministry or by SEIAA). The quantification of such liability will be recommended by Expert Appraisal Committee and finalized by Regulatory Authority. The bank guarantee shall be deposited prior to the grant of environmental clearance and will be released after successful implementation of the Remediation Plan and Natural & Community Resource Augmentation Plan.”

27. In short, it provides for grant of EC to category of ‘allowable/permissible’ projects. We must remember that the 2021 OM is applicable even to the completed projects. The 2021 OM says that grant of EC to such projects shall be effective from the date of issue. If the project proponent goes ahead with construction which requires EC under the EIA notification, it will amount to violation of the provisions of 1986 Act and 1986 Rules. It will attract penalty under Section 15 of the 1986 Act. Perusal of the provisions of Section 15 shows that even if the penalty is paid by the project proponent, it will not regularise the project. Therefore, even after the payment of penalty, if the project is under construction, the same has to be stopped and demolished 2644 [2025] 5 S.C.R. Supreme Court Reports and even if operation has already commenced, the same has to be stopped and demolished. Therefore, the construction work has to be demolished. 28. Now, we will consider what is the meaning of “ex post facto”. Various dictionary meanings can be summarised as under: a) Having retrospective effect or force; b) From a thing done afterwards; c) Retroactive or affecting something that has already happened.

29. Now, we will take a case of ex post facto EC provided under the 2017 notification. The effect of grant of ex post facto clearance is that if without obtaining EC, construction is in progress, the same is allowed to continue. If the construction is complete and operation and processes are going on, the same can go on after ex post facto EC is granted. Effect of grant of EC under clause (11) of 2021 OM will be grant of permission to complete the construction of the project, though construction had commenced without prior EC. Where the construction is already complete which is being used for processes etc., by grant of EC, the process/activities can continue. Thus, in effect, the EC granted under clause (11) of 2021 OM regularises something which was illegal with retrospective effect. In effect, the EC granted under clause (11) of 2021 OM will regularise the illegality done by commencing the construction or commencing the project without prior EC. Therefore, in substance, what is provided is grant of ex post facto EC. In other words what is granted is EC with retrospective effect as it regularises illegality committed earlier. The grant of EC under the 2021 OM, no doubt, is subject to making payment of compensation determined based on Polluter Pays Principle and undertaking activities relating to remedial plan. Once there is a violation of the EIA notification, the project proponent has to compensate following the Polluter Pays Principle. Even if, EC is not granted to him he has to pay for remedial plan to remedy the damage done to the environment. He has to also pay the penalty under Section 15 of the 1986 Act. Therefore, what is done by the 2021 OM is something which was completely prohibited by this Court in the cases of Common Cause2 and Alembic Pharmaceuticals3. It is an attempt to bring in an ex-post facto or retrospective regime by craftily drafting the SOP. The grant of EC under the 2021 OM in [2025] 5 S.C.R. 2645

Vanashakti v. Union of India substance and in effect amounts to ex post facto grant of EC. The Court must come down very heavily on the attempt of the Central Government to do something which is completely prohibited under the law. Cleverly, the words ex post facto have not been used, but without using those words, there is a provision to effectively grant ex post facto EC. The 2021 OM has been issued in violation of the decisions of this Court in the cases of Common Cause2 and Alembic Pharmaceuticals3. Therefore, we have no manner of doubt that the 2021 OM which permits grant of EC is completely arbitrary and illegal. Moreover, the 2021 OM does not refer to exercise of any power under the 1986 Act or the 1986 Rules.

30. There is one more aspect which is required to be noted. As per paragraph 14 of the 2017 notification, provision for grant of ex post facto EC was made only in relation to projects or activities which were in violation as of 14th March 2017. Therefore, grant of ex post facto clearance was not permitted under 2017 notification for the projects and activities which were commenced or continued after 14th March 2017. The window which was initially for a period of six months was eventually extended till completion of 30 days from 14th March 2018. Therefore, the 2021 OM is brought in to do something which was not permissible under the 2017 notification, the law laid down by this Court, and the solemn undertaking given by the Central Government to the Madras High Court. We must deprecate such effort on the part of the Central Government.

31. The EIA notification is of 14th September 2006. When the 2021 OM was issued, it was nearly 15 years old. Therefore, all project proponents were fully aware of the stringent requirements under the EIA notification. The 2021 OM seeks to protect the violations of the EIA notification which have taken place or continue to take place 15 years after the EIA notification came into force. Thus, the 2021 OM seeks to protect violators who have acted with full knowledge of consequences of violating the EIA notification. Those who violate the law regarding obtaining prior EC are not only committing gross illegality, but they are acting against the society at large. The violation of the condition of obtaining prior EC must be dealt with heavy hands. In environmental matters, the Courts must take a very strict view of the violations of the laws relating to the environment. It is the duty of the Constitutional Courts to do so. 2646 [2025] 5 S.C.R. Supreme Court Reports 32. Under Article 21 of the Constitution of India, the right to live in a pollution free environment is guaranteed. In fact, the 1986 Act has been enacted to give effect to this fundamental right. In 1977, fundamental duties of all citizens were incorporated in the Constitution which enjoined every citizen of India to protect and improve the environment as provided in clause (g) of Article 51A. Therefore, even the Central Government has a duty to protect and improve the natural environment.

33. Today, in the year 2025, we have been experiencing the drastic consequences of large-scale destruction of environment on human lives in the capital city of our country and in many other cities. At least for a span of two months every year, the residents of Delhi suffocate due to air pollution. The AQI level is either dangerous or very dangerous. They suffer in their health. The other leading cities are not far behind. The air and water pollution in the cities is ever increasing. Therefore, coming out with measures such as the 2021 OM is violative of fundamental rights of all persons guaranteed under Article 21 to live in a pollution free environment. It also infringes the right to health guaranteed under Article 21 of the Constitution.

34. The 2021 OM talks about the concept of development. Can there be development at the cost of environment? Conservation of environment and its improvement is an essential part of the concept of development. Therefore, going out of the way by issuing such OMs to protect those who have caused harm to the environment has to be deprecated by the Courts which are under a constitutional and statutory mandate to uphold the fundamental right under Article 21 and to protect the environment. In fact, the Courts should come down heavily on such attempts. As stated earlier, the 2021 OM deals with project proponents who were fully aware of the EIA notification and who have taken conscious risk to flout the EIA notification and go ahead with the construction/continuation/expansion of projects. They have shown scant respect to the law and their duty to protect the environment. Apart from violation of Article 21, such action is completely arbitrary which is violative of Article 14 of the Constitution of India besides being violative of the 1986 Act and the EIA notification. 35. We are, however, conscious of the fact that ex post facto EC may have been granted in certain cases both under the 2017 notification [2025] 5 S.C.R. 2647 Vanashakti v. Union of India and the 2021 OM. ECs already granted under 2017 notification and the 2021 OM, at this stage, should not be disturbed. 36. Hence, we pass the following order:

a) We hold that the 2017 notification and the 2021 OM as well as all circulars/orders/OMs/notifications issued for giving effect to these notifications are illegal and are hereby struck down; b) We restrain the Central Government from issuing circulars/ orders/OMs/notifications providing for grant of ex post facto EC in any form or manner or for regularising the acts done in contravention of the EIA notification; c) We clarify that the ECs already granted till date under the 2017 notification and the 2021 OM shall, however, remain unaffected. 37. The writ petitions and civil appeals are accordingly allowed on the above terms. Result of the case: Writ Petitions and Civil Appeals allowed. †Headnotes prepared by: Harshit Anand, Hony.

1. Part IV-A of the Constitution of India containing fundamental duties as set out in Article 51A was incorporated in the Constitution by the 42nd Amendment Act with effect from 3rd January 1977. Clause (g) 2622 [2025] 5 S.C.R. Supreme Court Reports of Article 51A provides that it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures. This Court in several decisions has held that the right to live in a pollution free atmosphere is a part of the fundamental right guaranteed under Article 21 of the Constitution of India. 2. The world changed rapidly after World War II. From the late 1960s and early 1970s, slowly there was a realisation about the drastic consequences of the destruction of environment and pollution of various kinds. In June 1972, at Stockholm, the United Nations Conference on Human Environment was held. In the said conference, several decisions were taken by the world community to protect the environment. 3. In our country, it took fourteen years thereafter for the legislature to come out with a law for protection and improvement of the environment. The Environment (Protection) Act, 1986 (for short, ‘the 1986 Act’) was brought into force with effect from 19th November 1986. As can be noticed from several orders of this Court and the High Courts, the progress of implementation of the 1986 Act has been very slow.

4. The 1970s and 1980s saw growth of industrialisation in our country. The activities such as mining, gas exploration, thermal power plants, petroleum refining industries, various other industries, building and construction projects, such as, highways started growing. 5. Again, it took twenty years after the 1986 Act came into force to exercise the power under sub-section (1) and clause (v) of sub-section (2) of Section 3 of the 1986 Act read with clause (d) of sub-rule (3) of Rule 5 of the Environment (Protection) Rules, 1986 (for short, ‘1986 Rules’) for coming out with the Environment Impact Assessment Notification, 2006 (for short, ‘the EIA notification’). The EIA notification was issued on 14th September 2006. It provided that the projects or activities mentioned in clause (2) thereof shall require prior Environmental Clearance (for short, ‘the EC’) from the concerned regulatory authority. The concerned regulatory authority in the Central Government is the Ministry of Environment Forests and Climate Change (for short, ‘the MoEFCC’) for matters falling under Category ‘A’ in the Schedule, and at the State level, the State Environment Impact Assessment Authority (for short, ‘the SEIAA’) for [2025] 5 S.C.R. 2623 Vanashakti v. Union of India the matters falling in Category ‘B’. In the Schedule, Categories ‘A’ and ‘B’ were incorporated setting out industries and other development work. The entire controversy in this group of petitions is about ex post facto grant of EC.

6. On 14th March 2017, a notification was issued by the MoEFCC. The said notification is hereafter referred to as ‘the 2017 notification’. The said notification was made applicable to the projects or activities that have started the work on site, expanded the production beyond the limit of the EC, or changed the production mix without obtaining EC. The 2017 notification provided that in case of such works, ex post facto EC can be granted. It provided that the projects or activities which are in violation of the EIA notification as on 14th March 2017 were eligible to apply under the 2017 notification for ex post facto EC within a period of six months from 14th March 2017. 7. The National Green Tribunal (for short, ‘the NGT’) vide order dated 24th May 2021 directed the MoEFCC to prepare a Standard Operating Procedure (for short, ‘the SOP’) for grant of EC in the cases of violation so as to address the gap in the binding law and practice being currently followed. In purported compliance with the said direction, Office Memorandum dated 7th July 2021 (for short, ‘the 2021 OM’) was issued.

8. In the meanwhile, the 2017 notification was challenged by way of a writ petition before the High Court of Madras in the case of Puducherry Environment Protection Association v. Union of India1, which was decided by order dated 13th October 2017. During the course of hearing of the case before the Madras High Court, when it was pointed out that the outer limit for making applications for grant of ex post facto EC have been repeatedly extended, the Union of India gave a categorical undertaking that the 2017 notification was only a one-time measure. By recording the said submission made on behalf of the Union of India that the 2017 notification was certainly and clearly only a one time measure, the High Court disposed of the petition. Later on, by order dated 14th March 2018 passed by the High Court of Madras in another case, the time period under the 2017 notification for submission of proposals by project proponents was extended by a further period of thirty days. 1 2017 SCC OnLine Mad 7056 2624 [2025] 5 S.C.R. Supreme Court Reports

9. In Writ Petition (C) No.1394 of 2023, the first prayer is for quashing the 2021 OM on the ground that it was arbitrary, illegal and ultra vires the provisions of the 1986 Act. The second prayer is for issuing a writ of mandamus directing the MoEFCC and SEIAA/SEACs not to process and entertain any application for ex-post facto EC after 13th May 2018. As stated earlier, the time granted under the 2017 notification to apply was lastly extended till 13th April 2018. 10. In Writ Petition (C) No.118 of 2019, the challenge is to the 2017 notification issued by the MoEFCC. A prayer was made seeking directions to the respondents to produce a list of real estate projects and project proponents who have undertaken real estate development projects without obtaining EC under the 2006 notification. 11. In Writ Petition (C) No.115 of 2024, the challenge is to the 2017 notification and the 2021 OM. A prayer for writ of prohibition is made for restraining the MoEFCC from issuing any notification or office memorandum permitting ex-post facto EC.

12. The High Court of Madras by judgment and order dated 30th August 2024 quashed the 2021 OM and another OM dated 19th February 2021. The challenge in Civil Appeal No.381-382 of 2025 is to this decision of the High Court of Madras. In the judgment and order dated 30th August 2024, the Madras High Court declared that its order will operate only prospectively and applications under consideration will remain unaffected. The challenge in this appeal is only to the extent of giving prospective effect to the impugned judgment. THE EIA NOTIFICATION 13. Firstly, we come to the EIA notification. It has been issued in exercise of powers under sub-Section (1) and clause (v) of sub-Section (2) of Section 3 of the 1986 Act read with clause (d) of sub-Rule (3) of Rule 5 of the 1986 Rules. Section 3 of the 1986 Act reads thus: “3. Power of Central Government to take measures to protect and improve environment.—(1) Subject to the provisions of this Act, the Central Government shall have the power to take all such measures as it deems necessary or expedient for the purpose of protecting and improving the quality of the environment and [2025] 5 S.C.R. 2625 Vanashakti v. Union of India preventing, controlling and abating environmental pollution. (2) In particular, and without prejudice to the generality of the provisions of sub-section (1), such measures may include measures with respect to all or any of the following matters, namely:—

(i) co-ordination of actions by the State Governments, officers and other authorities— (a) under this Act, or the rules made thereunder; or (b) under any other law for the time being in force which is relatable to the objects of this Act; (ii) planning and execution of a nation-wide programme for the prevention, control and abatement of environmental pollution; (iii) laying down standards for the quality of environment in its various aspects; (iv) laying down standards for emission or discharge of environmental pollutants from various sources whatsoever: Provided that different standards for emission or discharge may be laid down under this clause from different sources having regard to the quality or composition of the emission or discharge of environmental pollutants from such sources; (v) restriction of areas in which any industries, operations or processes or class of industries, operations or processes shall not be carried out or shall be carried out subject to certain safeguards; (vi) laying down procedures and safeguards for the prevention of accidents which may cause environmental pollution and remedial measures for such accidents; (vii) laying down procedures and safeguards for the handling of hazardous substances; (viii) examination of such manufacturing processes, materials and substances as are likely to cause environmental pollution; 2626 [2025] 5 S.C.R. Supreme Court Reports

(ix) carrying out and sponsoring investigations and research relating to problems of environmental pollution; (x) inspection of any premises, plant, equipment, machinery, manufacturing or other processes, materials or substances and giving, by order, of such directions to such authorities, officers or persons as it may consider necessary to take steps for the prevention, control and abatement of environmental pollution; (xi) establishment or recognition of environmental laboratories and institutes to carry out the functions entrusted to such environmental laboratories and institutes under this Act; (xii) collection and dissemination of information in respect of matters relating to environmental pollution; (xiii) preparation of manuals, codes or guides relating to the prevention control and abatement of environmental pollution; (xiv) such other matters as the Central Government deems necessary or expedient for the purpose of securing the effective implementation of the provisions of this Act.

(3) The Central Government may, if it considers it necessary or expedient so to do for the purposes of this Act, by order, published in the Official Gazette, constitute an authority or authorities by such name or names as may be specified in the order for the purpose of exercising and performing such of the powers and functions (including the power to issue directions under Section 5) of the Central Government under this Act and for taking measures with respect to such of the matters referred to in sub-section (2) as may be mentioned in the order and subject to the supervision and control of the Central Government and the provisions of such order, such authority or authorities may exercise the powers or perform the functions or take the measures so mentioned in the order as if such authority or authorities had been empowered by this Act to exercise those powers or perform those functions or take such measures.” (emphasis added) [2025] 5 S.C.R. 2627 Vanashakti v. Union of India

13.1 Sub-section (1) of Section 3 sums up the very object of the 1986 Act. Therefore, the EIA notification has been issued not only for the purposes of protecting and improving the quality of the environment but also for preventing and abating environmental pollution. Sub-section (1) of Section 3 confers general power of taking measures on the Central Government. Sub-section (2) confers specific power for taking measures in the matters set out in clauses (i) to (ix) thereof. Clause (v) of sub-section (2) of Section 3 empowers the Central Government to take measures for putting restrictions of areas in which any industries, operations or processes shall not be carried out or shall be carried out subject to safeguards. 14. Rule 5 of the 1986 Rules reads thus: “5. Prohibition and restriction on the location of industries and the carrying on of processes and operations in different areas.—(1) The Central Government may take into consideration the following factors while prohibiting or restricting the location of industries and carrying on of processes and operations in different areas: (i) Standards for quality of environment in its various aspects laid down for an area. (ii) The maximum allowable limits of concentration of various environmental pollutants (including noise) for an area. (iii) The likely emission or discharge of environmental pollutants from an industry, process or operation proposed to be prohibited or restricted.

(iv) The topographic and climatic features of an area. (v) The biological diversity of the area which, in the opinion of the Central Government needs to be preserved. (vi) Environmentally compatible land use. (vii) Net adverse environmental impact likely to be caused by an industry, process or operation proposed to be prohibited or restricted. 2628 [2025] 5 S.C.R. Supreme Court Reports (viii) Proximity to a protected area under the Ancient Monuments and Archaeological Sites and Remains Act, 1958 or a sanctuary, National Park, game reserve or closed area notified as such under the Wild Life (Protection) Act, 1972 or places protected under any treaty, agreement or convention with any other country or countries or in pursuance of any decision made in any international conference, association or other body. (ix) Proximity to human settlements. (x) Any other factor as may be considered by the Central Government to be relevant to the protection of the environment in an area. (2) While prohibiting or restricting the location of industries and carrying on of processes and operations in an area, the Central Government shall follow the procedure hereinafter laid down.

(3) (a) Whenever it appears to the Central Government that it is expedient to impose prohibition or restrictions on the location of an industry or the carrying on of processes and operations in an area, it may, by notification in the Official Gazette and in such other manner as the Central Government may deem necessary from time to time, give notice of its intention to do so. (b) Every notification under clause (a) shall give a brief description of the area, the industries, operations, processes in that area about which such notification pertains and also specify the reasons for the imposition of prohibition or restrictions on the location of the industries and carrying on of processes or operations in that area. (c) Any person interested in filing an objection against the imposition of prohibition or restrictions on carrying on of processes or operations as notified under clause (a) may do so in writing to the Central Government within sixty days from the date of publication in the notification in the Official Gazette. (d) The Central Government shall within a period of one hundred and twenty days from the date of publication [2025] 5 S.C.R. 2629 Vanashakti v. Union of India

of the notification in the Official Gazette consider all the objections received against such notification and may [within [seven hundred and twenty-five days [,and in respect of the States of Assam, Meghalaya, Arunachal Pradesh, Mizoram, Manipur, Nagaland, Tripura, Sikkim and Jammu and Kashmir in exceptional circumstance and for sufficient reasons within a further period of one hundred and eighty days,]] from such date of publication] impose prohibition or restrictions on location of such industries and the carrying on of any process or operation in an area: [Provided that on account of COVID-19 pandemic, for the purpose of this clause, the period of validity of the notification expiring in the financial year 2020-2021 and 2021-2022 shall be extended up to [30th June, 2022] or six months from the end of the month when the relevant notification would have expired without any extension, whichever is later.] [(4) Notwithstanding anything contained in sub-rule (3), whenever it appears to the Central Government that it is in public interest to do so, it may dispense with the requirement of notice under clause (a) of sub-rule (3).]”

14.1 For issuing the EIA notification, power has been exercised under clause (d) of sub-rule (3) of Rule 5 which empowers the Central Government to impose prohibition or restrictions on location of such industries and the carrying on any process or operation in an area. There is a power to impose complete prohibition on carrying on any process or operation in an area. Clause (2) of the EIA notification reads thus: “2. Requirements of prior Environmental Clearance (EC):- The following projects or activities shall require prior environmental clearance from the concerned regulatory authority, which shall hereinafter referred to be as the Central Government in the Ministry of Environment and Forests for matters falling under Category ‘A’ in the Schedule and at State level the State Environment Impact Assessment Authority (SEIAA) for matters falling under Category ‘B’ in the said Schedule and at District level, 2630 [2025] 5 S.C.R. Supreme Court Reports the District Environment Impact Assessment Authority (DEIAA) for matters falling under Category ‘B2’ for mining minerals in the said Schedule, before any construction work, or preparation of land by the project management except for securing the land, is started on the project or activity: (i) All new projects or activities listed in the Schedule to this notification;

(ii) Expansion, modernization or any change in the product mix or raw material mix in existing projects or activities listed in the Schedule to this notification with addition of capacity beyond the limits specified for the concerned sector in the said Schedule, subject to conditions and procedure provided in the sub-paragraph (ii) of paragraph 7.” 14.2 Therefore, without prior EC, construction of new projects or activities, expansion or modernisation of existing projects or activities listed in the Schedule entailing capacity addition with change in process or technology, cannot be undertaken. Entire procedure for grant of prior EC is laid down in the EIA notification. LEGALITY OF THE 2017 NOTIFICATION 15. The 2017 notification refers to the OMs dated 12th December 2012 and 27th June 2013 by which a process was sought to be established for grant of EC in the cases of violation of the EIA notification. It also refers to the judgment of the High Court of Jharkhand holding these two OMs as illegal. The same OMs were also quashed by the NGT as mentioned in the said notification. There are three recitals in the said notification which are relevant. Recital Nos.9 to 11 read thus:

“9. And whereas, the Ministry of Environment, Forest and Climate Change and State Environment Impact Assessment Authorities have been receiving certain proposals under the Environment Impact Assessment Notification, 2006 for grant of Terms of References and Environmental Clearance for projects which have started [2025] 5 S.C.R. 2631 Vanashakti v. Union of India the work on site, expanded the production beyond the limit of environmental clearance or changed the product mix without obtaining prior environmental clearance; 10. Whereas, the Ministry of Environment, Forest and Climate Change deems it necessary for the purpose of protecting and improving the quality of the environment and abating environmental pollution that all entities not complying with environmental regulation under Environment Impact Assessment Notification, 2006 be brought under compliance with in the environmental laws in expedient manner;

11. And whereas, the Ministry of Environment, Forest and Climate Change deems it necessary to bring such projects and activities in compliance with the environmental laws at the earliest point of time, rather than leaving them unregulated and unchecked, which will be more damaging to the environment and in furtherance of this objective, the Government of India deems it essential to establish a process for appraisal of such cases of violation for prescribing adequate environmental safeguards to entities and the process should be such that it deters violation of provisions of Environment Impact Assessment Notification, 2006 and the pecuniary benefit of violation and damage to environment is adequately compensated for;” 15.1 Thus, what was sought to be done was to protect the project proponents who committed gross illegality by commencing construction or commencing operation or process without obtaining prior EC as provided in the EIA notification. The 2017 notification was a one-time measure. Moreover, this Court in the case of Common Cause v Union of India & Ors.2, held in no uncertain terms that the concept of ex post facto or retrospective EC is completely alien to environmental jurisprudence including the EIA notification. The decision in the case of Common Cause2 was delivered on 2nd August 2 (2017) 9 SCC 499 2632 [2025] 5 S.C.R. Supreme Court Reports

2017. Notwithstanding the clear declaration of law which was made on 2nd August 2017, the Central Government did not withdraw the 2017 notification. 16. We may note here that this is not the first time that the concept of prior EC was brought into force. For this purpose, useful reference can be made to a decision of this Court in the case of Alembic Pharmaceuticals v. Rohit Prajapati3. It records that there was a notification of 27th January 1994 mandating prior EC for setting up and expansion of industrial projects falling within thirty categories. The issue before this Court was about the legality and validity of the circular dated 14th May 2002, which permitted obtaining of ex post facto EC. This Court specifically dealt with the challenge to the circular dated 14th May 2002. In paragraph 12, this Court noted the issue to be decided: “12. The issue to be adjudicated is whether in view of the requirement of a prior EC under the EIA Notification of 1994, a provision for an ex post facto EC to industrial units could be validly made by means of the Circular dated 14-5-2002.” 16.1 Thereafter, this Court considered Section 3(1) of the 1986 Act. In paragraph 21 this Court held thus:

“21. The omission in the appeal to make any attempt to sustain the Circular dated 14-5-2002 with reference to the provisions of Section 3 of the Environment (Protection) Act, 1986 is significant. For an action of the Central Government to be treated as a measure referable to Section 3 it must satisfy the statutory requirement of being necessary or expedient “for the purpose of protecting and improving the quality of the environment and preventing, controlling and abating environment pollution”. The Circular dated 14-5-2002 in fact does quite the contrary. It purported to allow an extension of time for industrial units to comply with the requirement of an EC. The EIA Notification dated 27-1-1994 mandated that an EC has to be obtained before embarking on a 3 (2020) 17 SCC 157 [2025] 5 S.C.R. 2633 Vanashakti v. Union of India new project or expanding or modernising an existing one.

The EIA Notification of 1994 has been issued under the provisions of the Environment (Protection) Act, 1986 and the Environment Protection Rules, 1986, with the object of imposing restrictions and prohibitions on setting up of new projects or expansion or modernisation of existing project. The measures are based on the precautionary principle and aim to protect the interests of the environment. The Circular dated 14-5-2002 allowed defaulting industrial units which had commenced activities without an EC to cure the default by an ex post facto clearance. Being an administrative decision, it is beyond the scope of Section 3 and cannot be said to be a measure for the purpose of protecting and improving the quality of the environment. The circular notes that there were defaulting units which had failed to comply with the requirement of obtaining an EC as mandated. The circular provided for an extension of time and inexplicably introduced the notion of an ex post facto clearance. In effect, it impacted the obligation of the industrial units to be in compliance with the law. The concept of ex post facto clearance is fundamentally at odds with the EIA Notification dated 27-1-1994. The EIA Notification of 1994 contained a stipulation that any expansion or modernisation of an activity or setting up of a new project listed in Schedule I “shall not be undertaken in any part of India unless it has been accorded environmental clearance”.

The language of the notification is as clear as it can be to indicate that the requirement is of a prior EC. A mandatory provision requires complete compliance. The words “shall not be undertaken” read in conjunction with the expression “unless” can only have one meaning : before undertaking a new project or expanding or modernising an existing one, an EC must be obtained. When the EIA Notification of 1994 mandates a prior EC, it proscribes a post activity approval or an ex post facto permission. What is sought to be achieved by the administrative Circular dated 14-5-2002 is contrary to the statutory Notification 2634 [2025] 5 S.C.R. Supreme Court Reports

dated 27-1-1994. The Circular dated 14-5-2002 does not stipulate how the detrimental effects on the environment would be taken care of if the project proponent is granted an ex post facto EC. The EIA Notification of 1994 mandates a prior environmental clearance. The circular substantially amends or alters the application of the EIA Notification of 1994. The mandate of not commencing a new project or expanding or modernising an existing one unless an environmental clearance has been obtained stands diluted and is rendered ineffective by the issuance of the administrative Circular dated 14-5-2002. This discussion leads us to the conclusion that the administrative circular is not a measure protected by Section 3. Hence there was no jurisdictional bar on NGT to enquire into its legitimacy or vires. Moreover, the administrative circular is contrary to the EIA Notification 1994 which has a statutory character. The circular is unsustainable in law.” (emphasis added) 16.2 Ultimately, in paragraph 23, this Court held thus:

The concept of an ex post facto EC is in derogation of the fundamental principles of environmental jurisprudence and is an anathema to the EIA Notification dated 27-1-1994. It is, as the judgment in Common Cause [Common Cause v. Union of India, (2017) 9 SCC 499] holds, detrimental to the environment and could lead to irreparable degradation. The reason why a retrospective EC or an ex post facto clearance is alien to environmental jurisprudence is that before the issuance of an EC, the statutory notification warrants a careful application of mind, besides a study into the likely consequences of a proposed activity on the environment. An EC can be issued only after various stages of the decision-making process have been completed. Requirements such as conducting a public hearing, screening, scoping and appraisal are components of the decision-making process which ensure that the likely impacts of the industrial activity or the expansion of an existing industrial activity [2025] 5 S.C.R. 2635 Vanashakti v. Union of India

are considered in the decision-making calculus. Allowing for an ex post facto clearance would essentially condone the operation of industrial activities without the grant of an EC. In the absence of an EC, there would be no conditions that would safeguard the environment. Moreover, if the EC was to be ultimately refused, irreparable harm would have been caused to the environment. In either view of the matter, environment law cannot countenance the notion of an ex post facto clearance. This would be contrary to both the precautionary principle as well as the need for sustainable development.” (emphasis added) 16.3 In fact, as noted in paragraph 22.1, the word ‘prior’ was not used in the EIA notification dated 27th January 1994. However, the words ‘shall not be undertaken’ were used. In the 2006 EIA notification, the word ‘prior’ appears at multiple places. 17. The issue of ex post facto EC was dealt with in the case of Common Cause2, In paragraph 108, a submission was recorded that the possibility of getting ex post facto EC was a signal to the mining leaseholders that obtaining an EC was not mandatory or that if it was not obtained, the default was retrospectively condonable. In paragraph 125, this Court held thus:

“125. We are not in agreement with the learned counsel for the mining leaseholders. There is no doubt that the grant of an EC cannot be taken as a mechanical exercise. It can only be granted after due diligence and reasonable care since damage to the environment can have a long-term impact. EIA 1994 is therefore very clear that if expansion or modernisation of any mining activity exceeds the existing pollution load, a prior EC is necessary and as already held by this Court in M.C. Mehta [M.C. Mehta v. Union of India, (2004) 12 SCC 118] even for the renewal of a mining lease where there is no expansion or modernisation of any activity, a prior EC is necessary. Such importance having been given to an EC, the grant of an ex post facto environmental clearance would be detrimental to the environment and could lead to irreparable 2636 [2025] 5 S.C.R. Supreme Court Reports degradation of the environment. The concept of an ex post facto or a retrospective EC is completely alien to environmental jurisprudence including EIA 1994 and EIA 2006. We make it clear that an EC will come into force not earlier than the date of its grant.” (emphasis added)

18. Therefore, there is already a concluded finding of this Court that the concept of ex post facto or retrospective EC is completely alien to environmental jurisprudence and the EIA notification. This view was reiterated by this Court in the case of Electrosteel Steels Ltd. v. Union of India and Ors.4,. In paragraph 72, this Court held thus: “72. There can be no doubt that the need to comply with the requirement to obtain environment clearance is non-negotiable. A project can be set up or allowed to expand subject to compliance of the requisite norms. Environmental clearance is granted on condition of the suitability of the site to set up the project from the environmental angle, and existence of necessary infrastructural facilities and equipment for compliance of environmental norms. To protect future generations, it is imperative that pollution laws be strictly enforced. Under no circumstances, can industries which pollute be allowed to operate unchecked and degrade the environment.” (emphasis added) 18.1 In this case, as well as in the case of Alembic Pharmaceuticals3, this Court exercised its jurisdiction under Article 142 of the Constitution and permitted ex post facto EC in particular cases considering the peculiar factual situation.

19. It is in this context that the legality and validity of the 2017 notification will have to be tested. Interestingly, in paragraph 10 of the notification, it is recorded that the MoEFCC deems it necessary for the purpose of protecting and improving the quality of environment and abating environmental pollution that all the entities not complying with the environmental regulation under EIA notification be brought 4 (2023) 6 SCC 615 [2025] 5 S.C.R. 2637 Vanashakti v. Union of India under compliance within the environmental laws in an expeditious manner. The object of protecting and improving the environment and preventing and abating environmental pollution was achieved by the EIA notification. The object of the 2017 notification appears to be to protect the industries and entities which violated the EIA notification. In fact, paragraph 14 of the 2017 notification is material which reads thus: “14. The projects or activities which are in violation as on date of this notification only will be eligible to apply for environmental clearance under this notification and the project proponents can apply for environmental clearance under this notification only within six months from the date of this notification.”

20. Moreover, the 2017 notification is completely in violation of the law laid down by this court in the case of Common Cause2 and Alembic Pharmaceuticals3. From the recitals of the 2017 notification, it is apparent that it was a one-time measure to protect those who were in violation as on the date of the 2017 notification. In view of the settled law, even a ‘one-time measure’ or ‘one-time relaxation’ was illegal. The 2021 OM encourages the entities who contributed to pollution by not obtaining prior EC. Whenever EC is granted, it is always conditional. Certain conditions are imposed to abate or reduce the pollution. Such one-time measures add to air and/or water pollution. Such measures infringe the right to live in a pollution free environment guaranteed by Article 21. Thus, the 2017 notification was completely illegal.

21. The Division bench of Madras High Court by judgment dated 13th October 2017, in the case of Puducherry Environment Protection Association1 dealt with the issue regarding the legality of the 2017 notification which was subject matter of challenge in a Public Interest Litigation. A very specific submission was made before the Madras High Court on behalf of the Central Government by the learned Additional Solicitor General, which is recorded in paragraph 4(i) of the judgment. Relevant portion of paragraph 4(i) reads thus: “4(i) With regard to precautionary principle, faced with the situation that ex post facto clearance and regularization dates have been repeatedly extended time and again by series of notifications, learned Additional Solicitor 2638 [2025] 5 S.C.R. Supreme Court Reports General at the bar, on instructions, submits that this impugned notification shall clearly and certainly be only a one time measure. We record this submission also. ………………………….............……………………………” (emphasis added) 21.1 This statement was treated as an undertaking of the Central Government, which is clear from paragraph 4(n) of the said judgment:

“4(n) We are convinced that paragraphs 3,4 and 5 of the impugned notification alluded to supra coupled with the two undertakings made on instructions by learned Additional Solicitor General that (a) public hearing can be read into paragraph 5 of the impugned notification and (b) this shall certainly and clearly be a one time measure, this writ petition can be closed and disposed of recording the above submissions. We do so.” (emphasis added) 21.2 It is in view of this undertaking that the High Court did not interfere. The Central Government is bound by this undertaking. It is the duty of the Central Government to comply with the undertaking in its true letter and spirit. 22. The period provided in the 2017 notification to apply for ex-post facto EC ended on 13th September 2017. In the case of Appaswamy Real Estates Limited v. Puducherry Environment Protection Association5, the request of the MoEFCC for extending the time provided in the 2017 notification was accepted. As a result, the OM dated 16th March 2018 was issued which permitted the project proponents to apply under the 2017 notification within thirty days from the date of the High Court order. What is pertinent to note is that notwithstanding the grant of extension of time to apply, there was no modification made to paragraph 14 of the 2017 notification which clarified that it is applicable only to those projects and activities 5 2018 SCC OnLine Mad 1283 [2025] 5 S.C.R. 2639 Vanashakti v. Union of India

which were in violation on the date of the said notification. Therefore, any project or activity or process which required EC under the EIA notification commenced after 14th March 2017 was not protected by the 2017 notification. 23. Apart from the fact that the very concept of grant of ex-post facto EC is illegal, it is not possible to understand why the Central Government made efforts to protect those who committed illegality by not obtaining prior EC in terms of the EIA notification. As the EIA notification was eleven years old when the 2017 notification was issued, there was no equity in favour of those who committed such gross illegality of not obtaining prior EC. The persons who acted without prior EC were not illiterate persons. They were companies, real estate developers, public sector undertakings, mining industries, etc. They were the persons who knowingly committed illegality. We, therefore, make it clear that hereafter, the Central Government shall not come out with a new version of the 2017 notification which provides for the grant of ex-post facto EC in any manner. LEGALITY AND VALIDITY OF THE 2021 OM SUBMISSIONS

24. The learned senior counsel appearing for the Petitioner submitted that post a series of judgments of this Court in Alembic3 and Common Cause2, it is not permissible to grant ex post facto EC. He further submits that the 2021 OM is in violation of the 1986 Act and the EIA notification. He submits that EC must be prior and cannot be granted ex post facto. While the 2021 OM does not expressly extend the timeline under the 2017 notification or mention ex post facto, the 2021 OM and its application has effectively allowed grant of ex post facto EC. 25. The main submission of the learned Additional Solicitor General is that the 2021 OM does not seek to grant ex-post facto EC. It is only an SOP. The learned ASG invited our attention to the contents of the SOP. Her submission is that it provides for the demolition of projects not allowable or permissible for want of EC. It also provides for the closure of projects allowable/permissible, if prior EC has not been taken as per the EIA notification. She submitted that even if EC is granted, it will be effective from the date of the issue, and therefore, it is not ex post facto. She submitted that before such EC 2640 [2025] 5 S.C.R. Supreme Court Reports

is granted, the project proponent will have to pay certain amounts as provided therein based on Polluter Pays Principle. Moreover, the project proponents will have to undertake activities relating to remedial plan and community accommodation plan. She also pointed out that the projects which are not allowable or permissible, shall be demolished. She also pointed out provisions regarding penalty, project proponents furnishing bank guarantee, etc. Thus, in short, her submission is that the object of the 2021 OM is to protect those projects and industries which could have been granted an EC under EIA notification before the date of commencement of activities, but proceeded to commence activities without EC. Her submission is that this measure has been taken to ensure that the huge spending on constructions is not lost and wasted. OUR VIEW 26. The basic submission by learned ASG is based on a premise that what is provided under the 2021 OM is not grant of ex-post facto EC. The relevant part of the 2021 OM is in paragraph 10 and 11, which read thus: “10.Standard Operating Procedure-Guiding Principles: i. Without prejudice to any other consequences, action has to be initiated under section 15 read with section 19 of The Environment (Protection) Act, 1986 against all violations. ii. Projects not allowable/permissible, for grant of EC, as per extant regulations: To be demolished.

iii. Projects allowable/permissible, if prior EC had been taken as per extant regulations: To be closed until EC is granted (if no prior EC has been taken) or to revert to permitted production level (in case prior EC has been granted). iv. Polluter pays: Violators to pay for violation period proportionate to the scale of project and extent of commercial transaction. v. Setting up a mechanism for reporting of violation to the regulatory authority(ies). [2025] 5 S.C.R. 2641 Vanashakti v. Union of India 11. SOP for dealing with the violation cases: Step 1: Closure or Revision Sl no. Status of EC Actions 1 If no prior EC has been Order to close its operation taken 2 If prior EC is available for Order to revert the activity / existing/old unit production to permissible limits. 3 If prior EC was not Restrict the activity /production required for earlier to the extent to which prior EC production level but is was not required now required Step 2: Action under Environment (Projection) Act, 1986 Action under section 15 read with section 19 of the Environment (Protection) Act, 1986 shall be initiated against the violators. Step: 3: Appraisal under EIA Notification, 2006 The permissibility of the project shall be examined from the perspective of whether such activity/project was at all eligible for the grant of prior EC. A. If not permissible:

i. The project shall be ordered for the demolition/closure after issuing show cause notice and providing an opportunity of hearing. Ex. If a red industry is functioning in a CRZ-I area which means that the activity was, in the first place, not permitted at the time of commencement of project. Therefore, the activity is not permissible and therefore it shall be closed & demolished. ii. Respective regulatory authorities shall issue directions under section 5 of the Environment (Protection) Act, 1986 for such closure & demolition of the project/activity. 2642 [2025] 5 S.C.R. Supreme Court Reports B. If permissible: i. As per extant regulations at the time of scoping, if it is viewed that the project activity is otherwise permissible, Terms of Reference (TOR) shall be issued with directions to complete the impact assessment studies & submit Environmental Impact Assessment (EIA) report & Environmental Management Plan (EMP) in a time bound manner. ii. Such cases of violation shall be subject to appropriate (a) Damage Assessment (b) Remedial Plan and (c) Community Augmentation Plan by the Central Level Sectoral Expert Appraisal Committees or State/ Union Territory Level Expert Appraisal Committees, as the case may be.

iii. The Competent Authority shall issue directions to the project proponent, under section 5 of the Environment (Protection) Act, 1986 on case to case basis mandating payment of such amount (as may be determined based on Polluter Pays principle) and undertaking activities relating to Remedial Plan and Community Augmentation Plan (to restore environmental damage caused including its social aspects). iv. Upon submission of the EIA & EMP report, the project shall be appraised by the Central Sectoral Expert Appraisal Committees or the State/Union Territory Level Expert Appraisal Committees, as the case may be, as if it was a new proposal. If, on examination of the EIA/EMP report, the project is considered permissible for operation as per extant regulations, the requisite Environmental Clearance shall be issued which shall be effective from the date of issue. v. However, during appraisal after examination if it is found that even though the project may be permissible but not environmentally sustainable in its present form/configuration/features then the project shall be [2025] 5 S.C.R. 2643 Vanashakti v. Union of India directed to be modified so that the project would be environmentally sustainable.

vi. If, however, it is not considered appropriate to issue EC, the project shall be directed to be demolished/ closed. If such proposal is a case of expansion, the project shall be directed to revert back to the extent of activity for which EC had been granted earlier or to revert back to the extent of activity for which EC was not required (as the case may be). vii. Central Sectoral Expert Appraisal Committees or the State/Union Territory Level Expert Appraisal Committees, as the case may be, may insist upon public hearing to be conducted for such categories of projects for which the EIA Notification 2006, as amended from time to time, requires the public hearing to be conducted. viii. The project proponent will be required to submit a bank guarantee equivalent to the amount of Remediation Plan and Natural & Community Resource Augmentation Plan with Central / the State Pollution Control Board (depending on whether it is appraised at Ministry or by SEIAA). The quantification of such liability will be recommended by Expert Appraisal Committee and finalized by Regulatory Authority. The bank guarantee shall be deposited prior to the grant of environmental clearance and will be released after successful implementation of the Remediation Plan and Natural & Community Resource Augmentation Plan.”

27. In short, it provides for grant of EC to category of ‘allowable/permissible’ projects. We must remember that the 2021 OM is applicable even to the completed projects. The 2021 OM says that grant of EC to such projects shall be effective from the date of issue. If the project proponent goes ahead with construction which requires EC under the EIA notification, it will amount to violation of the provisions of 1986 Act and 1986 Rules. It will attract penalty under Section 15 of the 1986 Act. Perusal of the provisions of Section 15 shows that even if the penalty is paid by the project proponent, it will not regularise the project. Therefore, even after the payment of penalty, if the project is under construction, the same has to be stopped and demolished 2644 [2025] 5 S.C.R. Supreme Court Reports and even if operation has already commenced, the same has to be stopped and demolished. Therefore, the construction work has to be demolished. 28. Now, we will consider what is the meaning of “ex post facto”. Various dictionary meanings can be summarised as under: a) Having retrospective effect or force; b) From a thing done afterwards; c) Retroactive or affecting something that has already happened.

29. Now, we will take a case of ex post facto EC provided under the 2017 notification. The effect of grant of ex post facto clearance is that if without obtaining EC, construction is in progress, the same is allowed to continue. If the construction is complete and operation and processes are going on, the same can go on after ex post facto EC is granted. Effect of grant of EC under clause (11) of 2021 OM will be grant of permission to complete the construction of the project, though construction had commenced without prior EC. Where the construction is already complete which is being used for processes etc., by grant of EC, the process/activities can continue. Thus, in effect, the EC granted under clause (11) of 2021 OM regularises something which was illegal with retrospective effect. In effect, the EC granted under clause (11) of 2021 OM will regularise the illegality done by commencing the construction or commencing the project without prior EC. Therefore, in substance, what is provided is grant of ex post facto EC. In other words what is granted is EC with retrospective effect as it regularises illegality committed earlier. The grant of EC under the 2021 OM, no doubt, is subject to making payment of compensation determined based on Polluter Pays Principle and undertaking activities relating to remedial plan. Once there is a violation of the EIA notification, the project proponent has to compensate following the Polluter Pays Principle. Even if, EC is not granted to him he has to pay for remedial plan to remedy the damage done to the environment. He has to also pay the penalty under Section 15 of the 1986 Act. Therefore, what is done by the 2021 OM is something which was completely prohibited by this Court in the cases of Common Cause2 and Alembic Pharmaceuticals3. It is an attempt to bring in an ex-post facto or retrospective regime by craftily drafting the SOP. The grant of EC under the 2021 OM in [2025] 5 S.C.R. 2645

Vanashakti v. Union of India substance and in effect amounts to ex post facto grant of EC. The Court must come down very heavily on the attempt of the Central Government to do something which is completely prohibited under the law. Cleverly, the words ex post facto have not been used, but without using those words, there is a provision to effectively grant ex post facto EC. The 2021 OM has been issued in violation of the decisions of this Court in the cases of Common Cause2 and Alembic Pharmaceuticals3. Therefore, we have no manner of doubt that the 2021 OM which permits grant of EC is completely arbitrary and illegal. Moreover, the 2021 OM does not refer to exercise of any power under the 1986 Act or the 1986 Rules.

30. There is one more aspect which is required to be noted. As per paragraph 14 of the 2017 notification, provision for grant of ex post facto EC was made only in relation to projects or activities which were in violation as of 14th March 2017. Therefore, grant of ex post facto clearance was not permitted under 2017 notification for the projects and activities which were commenced or continued after 14th March 2017. The window which was initially for a period of six months was eventually extended till completion of 30 days from 14th March 2018. Therefore, the 2021 OM is brought in to do something which was not permissible under the 2017 notification, the law laid down by this Court, and the solemn undertaking given by the Central Government to the Madras High Court. We must deprecate such effort on the part of the Central Government.

31. The EIA notification is of 14th September 2006. When the 2021 OM was issued, it was nearly 15 years old. Therefore, all project proponents were fully aware of the stringent requirements under the EIA notification. The 2021 OM seeks to protect the violations of the EIA notification which have taken place or continue to take place 15 years after the EIA notification came into force. Thus, the 2021 OM seeks to protect violators who have acted with full knowledge of consequences of violating the EIA notification. Those who violate the law regarding obtaining prior EC are not only committing gross illegality, but they are acting against the society at large. The violation of the condition of obtaining prior EC must be dealt with heavy hands. In environmental matters, the Courts must take a very strict view of the violations of the laws relating to the environment. It is the duty of the Constitutional Courts to do so. 2646 [2025] 5 S.C.R. Supreme Court Reports 32. Under Article 21 of the Constitution of India, the right to live in a pollution free environment is guaranteed. In fact, the 1986 Act has been enacted to give effect to this fundamental right. In 1977, fundamental duties of all citizens were incorporated in the Constitution which enjoined every citizen of India to protect and improve the environment as provided in clause (g) of Article 51A. Therefore, even the Central Government has a duty to protect and improve the natural environment.

33. Today, in the year 2025, we have been experiencing the drastic consequences of large-scale destruction of environment on human lives in the capital city of our country and in many other cities. At least for a span of two months every year, the residents of Delhi suffocate due to air pollution. The AQI level is either dangerous or very dangerous. They suffer in their health. The other leading cities are not far behind. The air and water pollution in the cities is ever increasing. Therefore, coming out with measures such as the 2021 OM is violative of fundamental rights of all persons guaranteed under Article 21 to live in a pollution free environment. It also infringes the right to health guaranteed under Article 21 of the Constitution.

34. The 2021 OM talks about the concept of development. Can there be development at the cost of environment? Conservation of environment and its improvement is an essential part of the concept of development. Therefore, going out of the way by issuing such OMs to protect those who have caused harm to the environment has to be deprecated by the Courts which are under a constitutional and statutory mandate to uphold the fundamental right under Article 21 and to protect the environment. In fact, the Courts should come down heavily on such attempts. As stated earlier, the 2021 OM deals with project proponents who were fully aware of the EIA notification and who have taken conscious risk to flout the EIA notification and go ahead with the construction/continuation/expansion of projects. They have shown scant respect to the law and their duty to protect the environment. Apart from violation of Article 21, such action is completely arbitrary which is violative of Article 14 of the Constitution of India besides being violative of the 1986 Act and the EIA notification. 35. We are, however, conscious of the fact that ex post facto EC may have been granted in certain cases both under the 2017 notification [2025] 5 S.C.R. 2647 Vanashakti v. Union of India and the 2021 OM. ECs already granted under 2017 notification and the 2021 OM, at this stage, should not be disturbed. 36. Hence, we pass the following order:

a) We hold that the 2017 notification and the 2021 OM as well as all circulars/orders/OMs/notifications issued for giving effect to these notifications are illegal and are hereby struck down; b) We restrain the Central Government from issuing circulars/ orders/OMs/notifications providing for grant of ex post facto EC in any form or manner or for regularising the acts done in contravention of the EIA notification; c) We clarify that the ECs already granted till date under the 2017 notification and the 2021 OM shall, however, remain unaffected. 37. The writ petitions and civil appeals are accordingly allowed on the above terms. Result of the case: Writ Petitions and Civil Appeals allowed. †Headnotes prepared by: Harshit Anand, Hony.
