Supreme Court rules unjust enrichment doctrine does not apply to provisional customs duty refunds

The Supreme Court ruled that the doctrine of unjust enrichment is not applicable to refunds arising from provisional customs duty assessments. The bench clarified that when duty payments are made provisionally pending final assessment, refund claimants are not required to establish that the financial burden of the tax was not passed on to ultimate consumers before securing their refund. The doctrine of unjust enrichment generally prevents taxpayers from receiving refunds for taxes already collected from customers, ensuring windfall gains are avoided.

However, provisional assessments represent an incomplete adjudication where final duty liabilities remain unascertained at the time of payment. Consequently, statutory mechanisms governing finalization and consequential refunds operate independently of standard unjust enrichment tests applicable to finalized regular assessments. Importers and customs consultants handling provisional assessment finalizations should immediately file refund applications for excess duties paid without worrying about consumer-incidence documentation.

Ensure all provisional assessment bonds and relevant bills of entry are systematically tracked to expedite refund processing upon finalization. Bottom line: provisional customs duty refunds can be claimed without satisfying the bar of unjust enrichment.
