(1) THIS appeal arises from the judgment dated 4/03/1983 of the Delhi High Court. The appellant had filed a writ petition in the High court, inter alia, challenging the levy of additional duty of customs under Section 3 of the Tariff Act. The High court following its decision in M/s Khandelwal Metal and Engineering Works and another vs. Union of India dismissed the writ petition. In the present appeal it was contended that the matter is similar to M/s Khandelwal Metal and Engineering Works & AnR.vs. UOI which was pending in this court. It is on that basis that this appeal was admitted. When this court decided the appeal arising from the Delhi High court in M/s Khandelwal Metal and Engineer Works & AnR.vs. UOI it was represented that the point involved in this appeal is different. M/s Khandelwal Metal & Engineering Works case was concerned with brass scrap whereas the present case was concerned with copper scarp. On that basis it was delinked. On 28/02/1999 it was represented to this court that the point in issue is identical to the one involved in CA No. 1354/1980, namely Hyderabad industries Ltd. &AnR.vs. UOI. Now that appeal has also beeh heard but it was represented that this appeal should be delinked and this prayer was accepted. (2) WE find that the question involved in this appeal essentially turns on the interpretation of the provisions of the statute. There are decisions of this court where these provisions have been interpreted. In any case, when there is no challenge to the validity of any statutory provision, we see no reason as to why a writ petition should have been filed byepassing the alternative remedy which is provided under the statute. On this short ground we dismiss this appeal, vacate the interim orders, direct the payment of the balance amount of duty along with interest @ 15% per annum with yearly rests. (3) IT will be open to the appellant to avail of such statutory remedy as may be available to it. If an appeal is filed within four weeks from today, the Department will take the lenient view in condoning the delay. SPECIAL LEAVE PETITION(C) 2152/1983 (4) LEAVE granted. (5) IN view of the decision of this court in M/s Khandelwal Metal & Engineering Works & AnR.vs. UOI 1985 (3 SCC 620 we see no reason to interfere in this appeal. If an appeal is filed within four weeks from today, the Department will take the lenient view in condoning the delay. SPECIAL LEAVE PETITION(C) 2152/1983 (4) LEAVE granted. (5) IN view of the decision of this court in M/s Khandelwal Metal & Engineering Works & AnR.vs. UOI 1985 (3 SCC 620 we see no reason to interfere in this appeal. The same is dismissed with liberty to the appellant to raise any other contention before the Department in an appeal, if the appeal is filed within four weeks from today. The interim orders of stay are vacated. The balance amount of duty should be paid within four weeks from today along with interest @ 15% per annum with yearly rests. If the appeal is filed within four weeks the delay will be condoned by the Department. There will be no order as to costs.
