Protest-based refund claims and unjust enrichment in central excise refund litigation

For the period before Rule 233B of the Central Excise Rules, 1944 introduced a prescribed protest procedure, contemporaneous endorsements on gate passes, PLAs and RT 12 returns were treated as sufficient proof that duty was paid under protest, so refund claims were not barred by limitation. The text also states that refund remained subject to the doctrine of unjust enrichment; where the appellate authority safeguarded revenue by allowing refund only if the duty burden had not been passed on to customers, no interference was called for. The impugned orders were sustained and the Revenue's appeals failed.

Issues: (i) Whether the refund claims were barred by limitation in view of the duty being treated as paid under protest; (ii) Whether the refund claims were affected by the doctrine of unjust enrichment.

Issue (i): Whether the refund claims were barred by limitation in view of the duty being treated as paid under protest.

Analysis: The relevant period was before the introduction of Rule 233B of the Central Excise Rules, 1944, when no prescribed procedure existed for lodging protest. Endorsements on the gate passes, PLAs and RT 12 returns recording that duty was paid under protest were treated as sufficient evidence of protest, and the absence of a separate protest letter did not alter that character.

Conclusion: The refund claims were not barred by limitation.

Issue (ii): Whether the refund claims were affected by the doctrine of unjust enrichment.

Analysis: The refund claim had to satisfy the doctrine of unjust enrichment, and the appellate authority had protected the revenue by directing that refund would be admissible only if the duty burden had not been passed on to customers. On that footing, no interference was warranted.

Conclusion: The refund claims were not disallowed on the ground of unjust enrichment.

Final Conclusion: The impugned orders were sustained and the Revenue's appeals failed.

Ratio Decidendi: In the absence of a prescribed protest procedure for the relevant period, contemporaneous endorsements can establish payment under protest for limitation purposes, and refund can be granted only subject to the doctrine of unjust enrichment.
