Refund of central excise duty and discovery of mistake of law: limitation under Section 11B bars late refund claims

Refund of central excise duty claimed on account of discovery of mistake of law is governed by the statutory refund regime and the prescribed limitation period. The legal basis requires refund applications to be filed within the time limit prescribed under Section 11B; only payments under an unconstitutional levy (i.e., paid without statutory authority) fall outside that limitation. A claimant cannot obtain refund merely by relying on another assessees favourable decision; the claimant must succeed in its own litigation to qualify for refund. Claims beyond the statutory period are barred and were dismissed.

Issues: (i) Whether the appellants are entitled to refund of central excise duty paid by reversal of CENVAT credit to avail Notification No.30/2004-C.E. based on favourable orders in other assessees' cases; (ii) Whether the impugned order dated 23.08.2018 rejecting the refund claim is legally sustainable under Section 11B of the Central Excise Act, 1944.

Issue (i): Whether the appellants are entitled to refund of central excise duty paid by reversal of CENVAT credit to avail Notification No.30/2004-C.E. based on favourable orders in other assessees' cases.

Analysis: The notification required that no credit of duty on inputs has been taken to avail the exemption; the appellants consciously reversed CENVAT credit on 17.07.2004 to comply with that condition and to clear final products duty free. CBIC/TRU communications of July 2004 presented two voluntary options to manufacturers: (a) continue to avail credit and pay duty at reduced rates, or (b) reverse credit to claim full exemption. The reversal undertaken by the appellants was a deliberate compliance step to avail the exemption and not an involuntary payment without legal authority. Reliance on decisions in other assessees' cases asserting retrospective applicability of Rule 11(3) cannot convert the appellants' voluntary reversal into a payment under a mistake of law.

Conclusion: The appellants are not entitled to refund on the ground that the reversal was a payment under a mistake of law; the reversal was a deliberate compliance to avail Notification No.30/2004-C.E. and does not merit refund on that basis.

Issue (ii): Whether the impugned order dated 23.08.2018 rejecting the refund claim is legally sustainable under Section 11B of the Central Excise Act, 1944.

Analysis: Section 11B prescribes filing of refund claims within one year from the relevant date (date of payment). The appellants paid by reversal on 17.07.2004 and filed Form-R on 02.06.2017, well beyond the one-year limitation. The Supreme Court's doctrine in Mafatlal requires refund claims, except in cases of unconstitutional levy, to be pursued under statutory refund provisions and within prescribed limitation; an assessee cannot invoke the doctrine of discovery of mistake of law (based on another's favourable decision) to escape statutory limitation. The facts show no unconstitutional or illegal levy; therefore the statutory one-year limitation governs the claim.

Conclusion: The impugned order rejecting the refund claim is legally sustainable as the claim is time-barred under Section 11B; the appeal does not succeed on merits or maintainability.

Final Conclusion: The statutory refund regime under Section 11B governs the claim and the appellants' refund application, filed after the one-year period from the date of payment, is barred and the appeal is dismissed.

Ratio Decidendi: Refunds of excise duty, except in cases of unconstitutional levy, are permissible only under and in accordance with Section 11B and attendant rules; claims filed beyond the one-year limitation from the relevant date are barred and an assessee cannot rely on decisions in other parties' cases to invoke the discovery-of-mistake-of-law doctrine to circumvent the statutory limitation.
