Finality of unchallenged waiver bars reopening of a refund claim in later proceedings.

A refund claim cannot be reopened after the assessee expressly waived the amount and the adjudication order recording that waiver was never challenged. The unchallenged order had attained finality, so the same refund could not be pursued in later proceedings. Reliance on the earlier tribunal decision was found inapposite because the relevant demand for the period had already been accepted as valid when Notification No. 51/93 was examined. The refund claim was therefore not entertainable.

Issues: Whether the refund claim of Rs. 5,70,000 was maintainable despite the earlier waiver and the unchallenged adjudication attaining finality.

Analysis: The claim for refund of Rs. 5,70,000 had been specifically waived by the assessee by letter dated 4.7.01. The adjudicating authority thereafter passed an order recording that waiver, and that order was never challenged. In view of the finality of that order, the assessee could not reopen the same claim in the present proceedings. The reliance placed on the earlier tribunal order was also found misplaced, as the demand for the relevant period had been conceded to be valid when Notification No. 51/93 dated 28.2.93 was examined.

Conclusion: The refund claim was not entertainable and the challenge failed.
