Excise refund limitation under section 11B does not bar consequential relief after appellate recognition of exemption conditions.

An exemption notification operated from the date it took effect once the prescribed conditions were met, so the refund or set-off of excise duty could not be defeated merely because departmental processing was delayed. The claim had already been made earlier, and the appellate authority had found that the goods were duty-paid inputs used in manufacture. In that context, the requirement of claiming the benefit at clearance became academic, and section 11B(3) allowed refund where duty became due because of an appellate order without requiring a fresh application. The claim was therefore not barred by limitation, and consequential refund or adjustment was payable.

Issues: Whether the claim for refund or set-off of excise duty, arising from an exemption notification and confirmed in appeal, was barred by limitation under section 11B.

Analysis: The exemption operated from the date of the notification once the prescribed conditions were satisfied, and the right to set-off or refund could not be defeated merely because the departmental machinery took time to process the claim. The claim had in fact been made earlier, and the appellate authority had already found that the goods were duty-paid inputs used in manufacture. In such a situation, the issue of claiming the benefit at the time of clearance became academic. Further, sub-section (3) of section 11B specifically permitted refund where duty became due as a result of an appellate order, without requiring a fresh claim.

Conclusion: The claim was not barred by limitation and the petitioner was entitled to the refund or adjustment.

Ratio Decidendi: Where exemption conditions are satisfied and refund or set-off becomes due by reason of an appellate order, limitation under section 11B does not defeat the claim, and the department must grant the consequential relief without insisting on a fresh time-barred application.
