Unjust enrichment and documentary proof in provisional assessment refunds: refund upheld where amendment was prospective and officer's computation was accepted.

Refund arising from finalisation of provisional assessments for a period prior to the operative amendment was held not subject to unjust enrichment, following the Larger Bench view that the amendment applies prospectively. The Tribunal also held that a refund based on deduction of carriage and freight from assessable value could not be rejected for want of further documentary proof where duty had already been computed and paid on the jurisdictional officer's own calculation. The refund was upheld in full and the Revenue's challenge failed on both grounds.

Issues: (i) Whether the refund claim could be rejected for want of further documentary proof regarding deduction of carriage and freight from the assessable value; (ii) Whether the doctrine of unjust enrichment applied to refund arising from finalisation of provisional assessments for the relevant period.

Issue (i): Whether the refund claim could be rejected for want of further documentary proof regarding deduction of carriage and freight from the assessable value.

Analysis: The refund arose from the Supreme Court's direction regarding deduction of carriage and freight from the assessable value. The duty on the relevant components had already been paid on the basis of computation made by the jurisdictional officer, and the assessee was only seeking refund on that same basis. In these circumstances, no additional document was shown to be necessary to establish the claim.

Conclusion: The objection on lack of documents was rejected and the Revenue's challenge on this issue failed.

Issue (ii): Whether the doctrine of unjust enrichment applied to refund arising from finalisation of provisional assessments for the relevant period.

Analysis: The goods were cleared under provisional assessment and the assessments were finalised later. The Tribunal followed the Larger Bench view that the linking of refund arising from provisional assessments with the unjust enrichment requirement, introduced by amendment, operated only prospectively and would not apply to provisional assessments relating to the period prior to the effective date of that amendment.

Conclusion: The doctrine of unjust enrichment was held not applicable, and the Revenue's challenge on this issue also failed.

Final Conclusion: The refund was upheld in full and the Revenue's appeal was dismissed.

Ratio Decidendi: Refund arising from finalisation of provisional assessments for a period prior to the operative amendment is not subject to unjust enrichment, and a refund claim based on the officer's own computation cannot be denied for want of additional documentary proof when the duty component itself was paid under that computation.
