Final refund entitlement cannot be reopened, and Section 11BB interest applies after three months of delay in sanctioning refund.

Once refund entitlement has been finally determined in appellate proceedings, the adjudicating authority cannot reopen that entitlement or reduce the refund by reapplying the limitation in Rule 173-L(1)(i) during later quantification. The authority is confined to computing the refund and interest in accordance with the final appellate order. Section 11BB interest on delayed refund applies where refund remains unpaid beyond three months from receipt of the refund application, and the deeming provision also covers refunds ordered by an appellate authority or court. The article states that interest follows from expiry of the statutory period when the refund is not timely sanctioned.

Issues: (i) Whether the adjudicating authority could reduce the refund claim by reapplying the time-limit in Rule 173-L(1)(i) of the Central Excise Rules, 1944 after the appellate authority had already held the assessee entitled to refund; (ii) Whether interest under Section 11BB of the Central Excise Act, 1944 was payable from the date of the refund application where the refund was ultimately sanctioned within three months.

Issue (i): Whether the adjudicating authority could reduce the refund claim by reapplying the time-limit in Rule 173-L(1)(i) of the Central Excise Rules, 1944 after the appellate authority had already held the assessee entitled to refund.

Analysis: The appellate authority's earlier order had conclusively held the assessee entitled to refund along with interest. In the subsequent round, the adjudicating authority was required only to compute the refund and interest in accordance with that final order. It could not reopen the entitlement issue, reassess the duty payable, or deny refund by invoking the limitation under Rule 173-L(1)(i).

Conclusion: The reduction of the refund amount was impermissible and the issue was decided against the Revenue.

Issue (ii): Whether interest under Section 11BB of the Central Excise Act, 1944 was payable from the date of the refund application where the refund was ultimately sanctioned within three months.

Analysis: Section 11BB applies once a refund becomes payable under Section 11B. The statutory scheme provides that interest accrues if the refund is not made within three months from receipt of the application. The Explanation creates a deeming fiction where refund is ordered by an appellate authority or court, treating such order as one under Section 11B(2) for the purposes of Section 11BB. The refund claim having remained unpaid beyond the statutory period, interest followed from the expiry of three months from the application date.

Conclusion: Interest under Section 11BB was payable and the issue was decided against the Revenue.

Final Conclusion: The appeal failed because the refund entitlement had already attained finality and the statutory conditions for interest on delayed refund were satisfied.

Ratio Decidendi: Once refund entitlement is finally determined in appellate proceedings, the adjudicating authority cannot reopen that entitlement in a subsequent quantification exercise, and interest under Section 11BB becomes payable when the sanctioned refund is not made within three months of receipt of the refund application, including where the refund is ordered by an appellate authority.
