Unjust enrichment bars excise duty refund where the duty burden was not passed on, requiring fresh reconsideration

Refund of excise duty is barred to the extent the duty burden has been retained by the assessee and not passed on to customers, because claims must be tested against the doctrine of unjust enrichment under the amended refund provisions. The Tribunal also noted that proceedings under Section 35E(2) did not require a prior notice under Section 11A in the manner suggested below. The refund question was therefore remanded for fresh reconsideration and redetermination after hearing the parties.

Issues: Whether refund of duty was barred by the doctrine of unjust enrichment and whether the matter required reconsideration in the light of the amended refund provisions.

Analysis: The Tribunal noted that refund is not admissible where the duty element has been retained by the assessee and not passed on to customers. It referred to the amended Section 11B of the Central Excise Act, 1944 and the principle affirmed by the Supreme Court that pending and granted refund claims are subject to unjust enrichment. The Tribunal also observed that proceedings under Section 35E(2) did not require a prior notice under Section 11A in the manner suggested by the lower appellate authority.

Conclusion: The refund issue was required to be reconsidered afresh in the light of the law on unjust enrichment, and the matter was remanded for redetermination after hearing the respondents.

Final Conclusion: The dispute was not finally decided on the merits of refund entitlement and was sent back for fresh adjudication under the amended refund regime.

Ratio Decidendi: Refund of excise duty is not permissible to the extent the duty burden has not been passed on, and refund claims must be tested against the doctrine of unjust enrichment.
