Refund claims need not fail for missing procedural enclosures, and unjust enrichment does not apply when duty incidence is not passed on.

A refund claim under a prescribed form cannot be rejected merely because documents listed as possible enclosures were not produced, where no statute or rule makes every enclosure mandatory and the claim can be decided on the material already on record. The requirement is procedural, not a ground for mechanical rejection. The doctrine of unjust enrichment also did not bar refund on the facts found, because the duty had been deposited provisionally against advance licences, the export obligation had been discharged, the DEEC book was logged, and the incidence of duty was not shown to have been passed on. The High Court therefore upheld the Tribunal's order allowing refund.

Issues: (i) Whether the enclosures mentioned in clause 9 of the refund application form were mandatory so as to justify rejection of the refund claims for non-production of documents; (ii) Whether, on the facts found, the doctrine of unjust enrichment barred the refund claims.

Issue (i): Whether the enclosures mentioned in clause 9 of the refund application form were mandatory so as to justify rejection of the refund claims for non-production of documents.

Analysis: The refund form merely listed the documents that could be enclosed with the application. No statutory provision or rule was shown to make production of every listed document mandatory. The requirement was therefore procedural, and the claims could not be rejected mechanically only because certain documents were not produced, especially when the claim could be examined on the basis of the material already on record.

Conclusion: The document requirement in clause 9 was not mandatory, and rejection of the refund claims solely for non-production of those documents was not justified.

Issue (ii): Whether, on the facts found, the doctrine of unjust enrichment barred the refund claims.

Analysis: The Appellate Tribunal recorded findings that the duty was deposited provisionally with reference to advance licences, the export obligation had been discharged, the DEEC book had been logged, and the exempt material was used in the manufacture of exported goods. On those facts, the incidence of duty was not shown to have been passed on, and the balance-sheet entries supported the claim that the deposit was reflected in the respondent's accounts.

Conclusion: The bar of unjust enrichment did not apply on the findings recorded.

Final Conclusion: The High Court found no substantial question of law and upheld the Tribunal's order allowing the refund claims.

Ratio Decidendi: A refund claim under a prescribed form cannot be rejected merely for non-production of documents listed as enclosures when the requirement is only procedural and the claim can be decided on the available record, and unjust enrichment does not arise where the duty incidence is not passed on on the facts found.
