Unjust enrichment does not apply in the same way to refund claims arising from finalisation of provisional excise assessments.

Excess duty paid during provisional assessment, when adjusted on finalisation of the assessment, is not subject to the same unjust enrichment test that applies to a normal refund claim. The Tribunal distinguished refund claims arising from provisional assessment finalisation from ordinary refunds, and held that excess duty should be adjusted against any short-paid duty at that stage. On that basis, the refund was not required to be examined under unjust enrichment under the Central Excise Act, and the Revenue's challenge failed. The orders allowing refund were sustained and the appeals were dismissed.

Issues: Whether refund arising on finalization of provisional assessment of excise duty is subject to the test of unjust enrichment under Section 11B of the Central Excise Act.

Analysis: The dispute concerned excess duty paid during provisional assessment, which was claimed as refund after final assessment. The Tribunal followed its earlier decision on the same issue and held that, in the context of finalization of provisional assessments, excess duty paid is to be adjusted against short-paid duty and the bar of unjust enrichment does not apply in the same manner as it does to a normal refund claim. The decision in Addison and Company was found distinguishable because it dealt with a normal refund and not with adjustment at the stage of provisional assessment finalization.

Conclusion: The refund claims were not required to be tested on unjust enrichment at the stage of finalization of provisional assessment and the Revenue's challenge failed.

Final Conclusion: The orders allowing refund were sustained and the Revenue's appeals were dismissed.

Ratio Decidendi: Excess duty paid during provisional assessment, when adjusted on finalization of the assessment, is not subject to the same unjust enrichment test applicable to a normal refund claim.
