Finality of unchallenged order bars re-litigation of identical refund recovery dispute between the same parties.

Finality of an earlier unchallenged order on an identical refund-recovery issue between the same parties barred the Revenue from re-agitating the dispute in a later proceeding. The text applies the principle that, where the same question arises on identical facts and has already been conclusively decided, a contrary view cannot be sustained in a subsequent matter. Rule 173-I was treated as governing credit for excess duty payment, and the earlier order concerning the same notice had attained finality. The impugned order was therefore set aside, with the issue resolved in favour of the assessee.

Issues: Whether the Revenue could re-agitate the recovery of refund when an earlier, identical order between the same parties on the same question had attained finality and had not been challenged.

Analysis: The dispute concerned recovery of refund granted on final assessment of RT-12 returns. An earlier order dealing with an identical notice for a subsequent period had held that Rule 173-I governed the grant of credit for excess duty payment, and that order had attained finality since the Revenue did not challenge it. When the same question arises between the same parties on identical facts, a contrary view cannot be sustained in a later proceeding. The finality of the earlier unchallenged order precluded the Revenue from reopening the same issue in the present matter.

Conclusion: The Revenue was barred from contesting the issue again, and the impugned order was set aside in favour of the assessee.

Final Conclusion: The appeal succeeded because the earlier final order on the same issue bound the parties and prevented a contradictory outcome in the present proceedings.

Ratio Decidendi: Where an identical issue between the same parties has already been finally decided and left unchallenged, a contrary subsequent order on that same issue cannot stand.
