Price variation clauses can support excise refund claims where contractual price reductions return excess duty and defeat unjust enrichment.

A genuine price variation clause in a contract can make an originally final excise assessment substantively provisional where the contract price is later reduced in accordance with that clause. On that basis, excess duty paid at clearance is refundable even though formal provisional assessment under Rule 7 of the Central Excise Rules, 2002 was not opted for. The doctrine of unjust enrichment does not bar the refund when the excess duty has been passed back to the buyer through the contractual price adjustment mechanism. The contrary authorities were distinguished because they did not involve a comparable contractual arrangement or downward price revision.

Issues: Whether excess excise duty paid at the time of clearance was refundable where the contract contained a price variation clause and the price was later reduced, despite the assessee not having opted for provisional assessment, and whether the doctrine of unjust enrichment barred the refund.

Analysis: The refund claim arose from a downward revision of the contractual price after clearance of the transformers. The earlier Tribunal decisions relied upon held that where the contract itself contains a price variation clause and the subsequent reduction in price is supported by the contractual arrangement and corresponding adjustment, the assessment is to be treated in substance as provisional even if the formal procedure under Rule 7 of the Central Excise Rules, 2002 was not followed. The Bench also noted that the objection based on unjust enrichment does not survive where the excess duty has been returned to the buyer through the price adjustment mechanism. The contrary decisions were distinguished on the basis that they did not involve a similar price variation clause or contractual arrangement showing provisional pricing.

Conclusion: The assessee was entitled to refund of the excess duty and the denial of refund was unsustainable.

Final Conclusion: The impugned order was set aside and the appeals were allowed with consequential relief.

Ratio Decidendi: Where a contract contains a genuine price variation clause and the price is subsequently reduced in accordance with that clause, excess duty paid on the original clearance is refundable notwithstanding the absence of formal provisional assessment, and unjust enrichment does not apply if the excess has been returned to the buyer.
