A of non-disclosure of such information by the assessee and suppression of relevant facts, the extended period of limitation was rightly invoked by the department. ·- The appellant-assessee, a manufacturer of electronics equipments, manufactured a machinery in the8 nature of testing equipments costing Rs.31.27 lacs to test its final products. A show cause notice was issued on the assessee demanding duty on the plant and machinery including the testing equipments manufactured by them. After considering the reply of the assessee, the C authorities confirmed the demand. The CEGAT dismissed the appeal filed by assessee. The instant appeal was filed challenging the order of the CEGAT.

Dismissing the appeal, the Court D HELD: 1. The demand for payment of central excise duty in the instant case was made on the basis of statement made by the appellant-assessee in their balance sheet to the effect that there was an addition to plant and machinery including testing equipments worth E Rs. 31.26 lacs which were made in the company by capitalisation of the expenditure on raw material, stores and spares and salary/wages and other benefits. The said statement and details were mentioned in Schedule 'Q' appended to notice of balance sheet and profit and F loss account of the appellant for the year ending December, 1987. The said position was further corroborated by the Director's report appearing in the Annual Report for the year ending December, 1988, wherein it was mentioned that during the year the G company developed a large number of testing equipments on its own for using the same for the testing of semi-conductors manufactured by it. Once the appellant had themselves made admission in their own balance sheet, which was not rebutted and was further H substantiated in the Director's report, they could not later " USHA RECTIFIER CORPN.

turn around and make submissions contrary to their own A admissions. Moreover, they also clearly took a stand in their reply to the said show cause notice that they bought various parts and components to develop the testing equipments for use within the factory and that such steps were undertaken to avoid importing of such equipments B from the developed countries with a view to save foreign exchange. Even if the testing equipments were used for captive consumption and within the factory premises, considering the fact that they were saleable and marketable, duty was payable on the said goods. The fact c that the equipments were marketable and saleable was also an admitted position as the appellant has admitted it in their reply to the show cause notice that they had undertaken such manufacturing process of the testing ,..__ equipments to avoid importing of such equipments. Such D a statement confirmed the position that such testing equipments were saleable and marketable. The provision of Explanations to Rule 9 and 49 of the Central Excise Rules are very clear as it provides that for the purpose of the said rules, excisable goods manufactured and E consumed or utilized as such would be deemed to have been removed from the premises immediately for such consumption or utilization. Jherefore, the contention that--no such duty could be levied unless it is shown that they were taken out from the factory premises is without any F merit.

directing them to show cause as to why central excise duty A should not be levied on it along with interest and penalty. The appellant submitted its reply to the aforesaid show cause notice wherein they took a stand that no manufacture of plant and machinery of the nature alleged had taken place during the year to warrant levy of central excise duty. It was further stated that B for research and development wing of the company and to carry out trials, experiments and for undertaking development job based on the latest technology available worldwide or through their own resources it had bought out items, parts, components, etc., and for that purpose such items were assembled in the c factory. It was also stated that after research is so done, and if it was not successful, the same was disassembled. It was contended that the job that was carried out in that process was purely for research and developmental works and it was not manufacture of testing equipments. In the said reply it was also D stated that project to develop the aforesaid testing equipment ,....._ for use within the factory was undertaken to avoid importing of such equipment from the developed countries with a view to ~ save foreign exchange but since the project failed, no serious effort had since been made to complete the manufacture of the E said testing equipments.

A aggrieved, the appellant filed an appeal before the CEGAT which was also rejected after hearing the counsel appearing for the parties and after extensively going through various facets arising in the case. Thereafter, the appellant has filed the present appeal on which we have heard the learned counsel s appearing for the parties.

5. It was submitted by the counsel appearing for the appellant that the appellant have their own research and development wing in which trials and experiments are undertaken from time to time for the developmental jobs based C on latest technology and that during the course of such trials and experiments they bought out various parts and components which were assembled by them and that after the research is done the same were disassembled and, therefore, such research and development process undertaken by them cannot D be said to be manufacturing process by any stretch of imagination. It was also submitted by the counsel that the aforesaid equipments were not taken out from the factory · premises of the appellant and rather they were dismantled and, therefore, the respondent acted illegally in levying tax on the E said goods. He also submitted that the department was also not entitled to invoke the extended period of limitation inasmuch as there was no cause for invoking the provision of extended limitation.

6. The aforesaid submissions of the counsel appearing for. F the appellant were however refuted by the counsel appearing for the respondent. We have very carefully scrutinized the records and examined the submissions of the counsel appearing for the parties in the light of the said records. G 7. The demand for payment of central excise duty in the present .case appears to have been made on the basis of statement made by the appellants in their balance sheet to the effect that there is an addition to plant and machinery including testing equipments worth Rs. 31.26 lacs which have been made H in the company by capitalisation of the expenditure on (i) raw ' ,, USHA RECTIFIER CORPN.

The aforesaid statement and details were mentioned in Schedule 'Q' appended to notice of balance sheet and profit and loss account of the appellant for the year ending December, 1987. Serial No. 6 of the said Schedule reads as follows: -B "Addition to plant and machinery includes testing equipments worth Rs. 31.26 lakhs fabricated in the company by capitalisation of following expenditure:-.,.- (i) Raw material Rs. 26.31 lakhs, ~ c (ii) Stores and spares Rs. 0.02 lakh, and (iii) Salary/wages and other benefits Rs. 4.93 lakhs (On the basis of estimated time spent)"

The aforesaid position is further corroborated by the D Director's report appearing at page no. 2 of the Annual Report for the year ending December, 1988, wherein it was mentioned that during the year the company developed a large number of testing equipments on its own for using the same for the testing of semi-conductors. Once the appellant has themselves made E admission in their own balance sheet, which was not rebutted and was further substantiated in the Director's report, the appellant now cannot turn around and make submissions which are contrary to their own admissions. (See: Calcutta Electric - Supply Corpn. v. CWT, (1972) 3 SCC 222 para 8). Moreover, F they have also clearly taken a stand in their reply to the aforesaid show cause notice that they bought various parts and . components to develop the testing equipments for use within · ' the factory and that such steps were undertaken to avoid importing of such equipments from the developed countries with G a view to save foreign exchange. -·~ 9.

10. Even if such equipments were used for captive consumption and within the factory premises, considering the fact that they are saleable and marketable, we are of the view that duty was payable on the said goods. The fact that the B equipments were marketable and saleable is also an admitted position as the appellant has admitted it in their reply to the show cause notice that .they had undertaken such manufacturing process of the testing equipments to avoid importing of such equipments from the developed countries with a view to save C foreign exchange. Such a statement confirms the position that such testing equipments were saleable and marketable. 11. The provision of Explanations to Rule 9 and 49 of the Central Excise Rules are very clear as it provides that for the purpose of the said rules excisable goods manufactured and0 consumed or utilized as such would be deemed to have been removed from the premises immediately for such consumption or utilization. Therefore, the contention that no such duty could be levi~d unless it is shown that they were taken out from the E factory premises is without any merit.

The aforesaid contention is also found to be without F any merit as the appellant has not obtained L-4 licence nor they had disclosed the fact of manufacturing of the aforesaid goods to the department. The aforesaid knowledge of manufacture came.to be acquired by the department only subsequently and in view of non-disclosure of such information by the appellant -G and suppression of relevant facts, the extended period of limitation was rightly invoked by the department. 13.
