Provisional assessment and unjust enrichment in excise refunds: commercial price adjustments did not replace statutory compliance.

Refund claims based on alleged provisional duty payments were barred by limitation because no application for provisional assessment was made and no provisional assessment order was passed; commercial descriptions of prices as provisional did not satisfy the statutory mechanism. The rejection of those refund claims was therefore upheld. Where supply contracts contained a price variation clause and the final price was later reduced, with excess duty adjusted through subsequent payments, the incidence of duty was not shown to have been passed on to buyers. On those facts, unjust enrichment did not bar the refund, and the Revenue's challenge failed.

Issues: (i) Whether the refund claims were barred by limitation under Section 11B(1) of the Central Excise Act, 1944 on the plea that the duty payments were in the nature of provisional payments. (ii) Whether the refund claims were hit by unjust enrichment where the contracts provided for provisional prices and subsequent price adjustments.

Issue (i): Whether the refund claims were barred by limitation under Section 11B(1) of the Central Excise Act, 1944 on the plea that the duty payments were in the nature of provisional payments.

Analysis: The record showed that no application had been made for provisional assessment and no order for provisional assessment had been passed. Provisional assessment is a distinct statutory mechanism under Rule 7B of the Central Excise Rules and requires compliance with prescribed conditions. In the absence of any application or order for provisional assessment, the duty payments could not be treated as provisional merely because the price was stated to be provisional in commercial terms.

Conclusion: The refund claims were barred by limitation and the rejection of the assessee's claims was upheld.

Issue (ii): Whether the refund claims were hit by unjust enrichment where the contracts provided for provisional prices and subsequent price adjustments.

Analysis: The contracts with the buyers contained a price variation clause and the prices were expressly provisional, subject to later revision. When the final price was fixed lower than the provisional price, the excess amount paid towards price and duty was adjusted by the buyer from subsequent payments. On these facts, the incidence of duty was not shown to have been passed on to the buyers. The reasoning followed the earlier Tribunal view that such contractual adjustment negates unjust enrichment.

Conclusion: The bar of unjust enrichment did not apply and the Revenue's challenge to the refund grant failed.

Final Conclusion: The assessee's challenge to the limitation issue failed, but the Revenue's challenge on unjust enrichment also failed, leaving the refund position undisturbed in the matters where it had been granted.

Ratio Decidendi: Refund claims cannot be treated as based on provisional assessment unless the assessee has sought and obtained provisional assessment under the prescribed rules, but where the contract itself contains a price variation clause and excess duty is adjusted through later payments, the incidence of duty is not regarded as passed on for the purposes of unjust enrichment.
