Provisional assessment refund: unjust enrichment does not apply to pre-amendment claims arising from finalisation of duty

Refund arising from finalisation of provisional assessment under Rule 9B(5) could not be denied merely for want of fresh supporting documents where the final assessment orders already recorded the relevant duty calculations and refund position. The doctrine of unjust enrichment was held inapplicable to such refunds for periods before the prospective 25-6-1999 amendment, because the refund flowed from adjustment on finalisation of provisional assessment and was treated as outside Section 11B of the Central Excise Act. The refund claims were therefore admissible.

Issues: (i) Whether the refund claim arising from finalisation of provisional assessment could be denied for want of supporting documents and proof of duty payment. (ii) Whether the principle of unjust enrichment applied to such refund claims under Rule 9B(5) of the Central Excise Rules, 1944 before the 25-6-1999 amendment.

Issue (i): Whether the refund claim arising from finalisation of provisional assessment could be denied for want of supporting documents and proof of duty payment.

Analysis: The assessments had been provisionally made and were later finalised on the basis of the data and certificate furnished by the assessee. The finalisation orders themselves recorded the monthly despatches, duty paid, brandwise calculations, deductions allowed, and the revised duty payable or refundable. In that situation, the Department could not insist again on further documents to disprove payment or to defeat the refund flowing from the final assessment.

Conclusion: The objection based on non-submission of documents was rejected and the refund could not be denied on that ground.

Issue (ii): Whether the principle of unjust enrichment applied to such refund claims under Rule 9B(5) of the Central Excise Rules, 1944 before the 25-6-1999 amendment.

Analysis: Refund arising from adjustment on finalisation of provisional assessment was held to fall outside Section 11B of the Central Excise Act, 1944, as laid down by the Constitution Bench in Mafatlal Industries and followed in later decisions. The amendment to Rule 9B(5) was treated as prospective, and the assessments in question had been finalised before that amendment came into force. Therefore, the doctrine of unjust enrichment was not attracted to these refund claims.

Conclusion: The principle of unjust enrichment did not apply and the refund was admissible to the assessee.

Final Conclusion: The refund claims arising from finalisation of provisional assessments were held to be allowable, and the assessee succeeded in the appeal.

Ratio Decidendi: Refund consequent upon finalisation of provisional assessment under Rule 9B(5) of the Central Excise Rules, 1944, prior to the prospective amendment, is not governed by Section 11B of the Central Excise Act, 1944 and is not subject to the doctrine of unjust enrichment.
