Finality of adjudication bars fresh proceedings for the same period after an exemption dispute has been conclusively decided.

Fresh show cause proceedings could not be initiated for the same period once the exemption dispute had been finally decided on merits. The earlier Supreme Court ruling had already held that the assessee was not required to prove ownership of the factory to claim exemption under Notification No. 30/81-C.E., and that conclusion had reversed the Tribunal's denial of relief for that period. A general observation in that judgment permitting action "in accordance with law" did not authorise reopening a concluded matter. The demand and appellate order were therefore unsustainable, and the appeals succeeded.

Issues: Whether fresh show cause proceedings could be initiated for the same period after the dispute had already been concluded by the Supreme Court in the assessee's favour on the exemption issue.

Analysis: The earlier Supreme Court decision had held that the assessee was not required, in the proceedings then before it, to prove ownership of the factory for claiming the exemption under Notification No. 30/81-C.E. and had set aside the Tribunal's denial of relief. The Tribunal's view had thus been reversed on merits and the matter stood finally concluded for the same period. The observation in that judgment permitting the Revenue to issue notice again could not be read as authorising a fresh round of proceedings on the very same period already decided. That observation was only to indicate that, if the Revenue had any surviving case in law, action could be taken in accordance with law, not to reopen a concluded dispute. The cited Bombay High Court decision on limitation did not assist the Revenue because it dealt with a different context and did not permit reopening of finally adjudicated demands.

Conclusion: Fresh proceedings for the same period were not maintainable, and the impugned demand and appellate order were unsustainable.

Final Conclusion: The appeals succeeded, and the demand was quashed because the earlier Supreme Court ruling had already concluded the exemption dispute for the relevant period.

Ratio Decidendi: Where a dispute for a specific period has been finally decided on merits, a general observation in the earlier judgment cannot be used to reopen the same concluded matter by issuing a fresh notice for that very period.
