Finality of prior tribunal orders bars identical duty demands and penalties when the department leaves earlier decisions unchallenged.

Identical customs/excise duty demands and penalties were found unsustainable where the Tribunal had already rejected the same issue in earlier matters and those orders had attained finality because the Department did not challenge them further. The Tribunal applied the principle that unchallenged prior decisions on the same facts and issue must be followed in later identical proceedings. On that basis, the duty and penalty confirmations in the assessees' matters were set aside, while the order dropping demand in the departmental appeal was left undisturbed.

Issues: Whether the impugned duty demands and penalties could be sustained when identical demands had already been rejected by the Tribunal in earlier cases and the Department had not challenged those decisions.

Analysis: The Tribunal noted that similar issues had been decided earlier against the Department and that those decisions had attained finality because no further appeal had been filed. It held that when the Department accepts earlier Tribunal orders on the same issue and does not pursue them further, the ratio of those orders must be followed in later, identical matters. On that basis, the confirmation of duty and penalty in the assessees' appeals could not stand, while the Commissioner's order dropping demand in the departmental appeal required no interference.

Conclusion: The duty demands and penalties in the assessees' appeals were set aside and those appeals were allowed; the Department's appeal was rejected.

Final Conclusion: Identical tax demands cannot be sustained once earlier Tribunal decisions on the same issue have attained finality and remain unchallenged by the Department.

Ratio Decidendi: Where the Department has accepted earlier Tribunal decisions on an identical issue by not challenging them further, later proceedings on the same facts must follow those decisions and cannot sustain contrary demands or penalties.
