Unamended exemption notification covered manufacturing-use refractories, and wrongly availed credit remained recoverable within statutory limitation.

Under the unamended Notification No. 201/79-C.E., Tariff Item 68 goods used in the manufacturing process could qualify for relief even if they did not become constituent parts of the finished product, so refractories used as moulds or for filling molten metal were eligible for the pre-amendment period subject to proof of actual use. Recovery of credit wrongly availed under the scheme was treated as recovery of short levy, and the statutory limitation for such recovery applied notwithstanding the notification's silence on time limits. The amendment narrowing the exemption operated prospectively only.

Issues: (i) Whether refractories used as moulds or for filling molten metal were eligible for benefit under Notification No. 201/79-C.E. prior to its amendment on 28-2-1982. (ii) Whether recovery of wrongly availed credit under the notification was governed by the limitation period under Section 11A.

Issue (i): Whether refractories used as moulds or for filling molten metal were eligible for benefit under Notification No. 201/79-C.E. prior to its amendment on 28-2-1982.

Analysis: The notification, as it stood before amendment, exempted excisable goods to the extent of duty already paid on Tariff Item 68 goods used in manufacture, without confining the benefit to goods that became raw materials or component parts of the finished product. The earlier Tribunal view had already held that moulds and similar items, though not forming part of the final product, could qualify if used in the manufacturing process under the unamended language. The later amendment narrowed the scope, but only prospectively.

Conclusion: The benefit of Notification No. 201/79-C.E. was available for the relevant pre-amendment period in respect of refractories used as moulds or in the described manufacturing process, subject to factual verification of actual use.

Issue (ii): Whether recovery of wrongly availed credit under the notification was governed by the limitation period under Section 11A.

Analysis: Credit wrongly taken under the notification effectively results in short collection of duty on the finished goods for which such credit is utilised. Since the notification could not override the substantive recovery provision, the statutory limitation for recovery of short levy applied even though the notification itself did not specify a time limit. The shorter or longer limitation period depended on the factual position regarding application for the benefit.

Conclusion: Section 11A applied to recovery of wrongly availed credit, and the contention that no time limit governed such recovery was rejected.

Final Conclusion: The decision sustained the assessee's entitlement to the notification benefit for pre-amendment refractories used in the manufacturing process, while also affirming that recovery of wrongly taken credit remained subject to the statutory limitation under Section 11A.

Ratio Decidendi: Under the unamended exemption notification, Tariff Item 68 goods used in the manufacturing process need not become constituent parts of the finished product to qualify for relief, but any wrongly availed credit under the scheme is recoverable as short levy within the statutory limitation period.
