Provisional assessment adjustment is limited by refund rules and unjust enrichment under central excise law.

Rule 7 of the Central Excise Rules, 2001, read with the earlier Rule 9B and Sections 11A and 11B of the Central Excise Act, 1944, does not confer a freestanding right to set off excess duty paid against a short payment when provisional assessment is finalised. The term "adjusted" under Rule 9B is limited to adjustment within the same provisional-to-final assessment process, not automatic cross-adjustment against other liabilities. Any excess amount becomes refundable only after final assessment and only if the assessee proves that the duty burden was not passed on, failing which the bar of unjust enrichment applies and the amount may be credited to the Consumer Welfare Fund.

Issues: Whether an assessee, on finalization of provisional assessment, is entitled to have excess duty payment adjusted against short payment without first applying the statutory refund mechanism and without attracting the bar of unjust enrichment.

Analysis: Rule 7 of the Central Excise Rules, 2001 and the corresponding earlier Rule 9B of the Central Excise Rules, 1944 provide for provisional assessment, final assessment, payment of deficiency, and refund of excess, but they do not create a freestanding right to adjustment of excess duty against another duty liability at the stage of finalization. The expression "adjusted" in Rule 9B was confined to adjustment of provisional duty against final duty under the same assessment process. The scheme of Rule 7, read with Sections 11A and 11B of the Central Excise Act, 1944, shows that any excess amount becomes refundable only after final assessment, and such refund is subject to the doctrine of unjust enrichment and, where applicable, credit to the Consumer Welfare Fund. The assessee must establish non-passing of the duty burden before any amount can be treated as actually refundable.

Conclusion: The assessee is not entitled to automatic adjustment of excess duty at the stage of finalization of provisional assessment; any adjustment can be considered only to the extent the amount is refundable under the statute and not hit by unjust enrichment.
