Finality of unchallenged merits findings prevents revival of excise duty demand and consequential penalty.

When the Revenue does not challenge the Tribunal's merits-based deletion of excise duty demand, those factual findings attain finality and the demand cannot be revived. On that footing, consequential penalty also cannot survive because it depends on the existence of a valid duty liability. Applying the same reasoning to the later connected appeals, the Supreme Court found no basis to interfere and left the Tribunal's exoneration of the assessees intact.

Issues: Whether the Revenue's appeals could succeed when the Tribunal's findings on merits were not challenged, and whether, in that situation, any differential excise duty or penalty could survive.

Analysis: The Tribunal had set aside the demand and penalty on merits, and the Revenue did not assail those findings before the Court. In the absence of any challenge to the merits, the Tribunal's factual findings stood confirmed. Once it was accepted that no differential duty was payable, the foundation for penalty also disappeared. The later set of appeals, which followed the same reasoning as the earlier order, stood on the same footing and called for no interference.

Conclusion: The appeals failed. The decision was in favour of the assessee, and the demand as well as the penalty did not survive.

Final Conclusion: The common order left intact the Tribunal's exoneration of the assessees from differential excise duty and consequential penalty, resulting in dismissal of the Revenue's challenges.

Ratio Decidendi: Where the merits of the Tribunal's deletion of duty demand are not challenged, those findings attain finality, and consequential penalty cannot be sustained.
