Refund claims under excise law require limitation compliance, proof of payment, and rebuttal of unjust enrichment; post-clearance credit notes do not help.

The note explains that a refund claim under the Central Excise regime must satisfy Section 11B, including limitation and proof that the tax incidence was not passed on. It states that the High Court had jurisdiction under Section 35G(1) because the dispute did not concern the rate or value of goods, but the refund itself was time-barred since the tax had been finally paid and not under provisional assessment. It further notes that documentary proof of payment and rebuttal of the statutory presumption under Section 12B were required, and that account entries or post-clearance credit notes did not defeat unjust enrichment. The revenue appeal succeeded and the refund rejection was restored.

Issues: (i) whether the High Court had jurisdiction under Section 35G(1) of the Central Excise Act, 1944 to entertain the revenue appeal; (ii) whether the refund claim was barred by limitation under Section 11B of the Central Excise Act, 1944; (iii) whether the refund could be granted without documentary proof of payment of the tax and without establishing that the incidence was not passed on; and (iv) whether adjustment by credit note or similar means after clearance of goods could defeat the bar of unjust enrichment.

Issue (i): Whether the High Court had jurisdiction under Section 35G(1) of the Central Excise Act, 1944 to entertain the revenue appeal.

Analysis: The appeal did not involve determination of the rate of duty or the value of goods for assessment. The dispute was confined to whether the assessee could obtain refund of service tax paid on transportation charges after a downward revision in tariff, and whether the refund claim satisfied the statutory requirements of limitation and unjust enrichment. Such questions were not of the class excluded from Section 35G(1).

Conclusion: The High Court had jurisdiction and the preliminary objection was rejected.

Issue (ii): Whether the refund claim was barred by limitation under Section 11B of the Central Excise Act, 1944.

Analysis: Section 11B makes the limitation period run from the relevant date, and the special rule for provisional assessment applies only where the assessment is in fact provisional. The service provider had not sought or obtained provisional assessment and had paid tax finally. The later reduction in tariff did not convert the original payment into a provisional one, and the refund claim was therefore governed by the ordinary limitation under Section 11B.

Conclusion: The refund claim was time-barred.

Issue (iii): Whether the refund could be granted without documentary proof of payment of the tax and without establishing that the incidence was not passed on.

Analysis: A claimant seeking refund must substantiate payment and entitlement by documentary evidence. Section 12B raises a statutory presumption that the incidence of duty has been passed on, and the burden lies on the claimant to rebut it. The materials relied upon, including account entries and certificates, were found insufficient to establish either actual payment into Government account in the manner claimed or that the tax burden had not been transferred to buyers.

Conclusion: The assessee failed to discharge the burden of proof, and refund was not admissible.

Issue (iv): Whether adjustment by credit note or similar means after clearance of goods could defeat the bar of unjust enrichment.

Analysis: Once the burden of tax has formed part of the cost and been recovered through the pricing of the final product, a later credit note or post-clearance adjustment does not undo the passing on of incidence. The doctrine of unjust enrichment continues to apply, and a subsequent accounting adjustment cannot by itself create a right to refund.

Conclusion: Post-clearance credit notes did not entitle the assessee to refund.

Final Conclusion: The revenue appeal succeeded, the Tribunal's order was set aside, and the rejection of the refund claim was restored on the grounds of limitation and unjust enrichment.

Ratio Decidendi: A refund claim under the Central Excise regime must satisfy the statutory requirements of Section 11B, including limitation and proof that the incidence of tax has not been passed on, and a payment made by a non-provisional assessment cannot be treated as provisional merely because the underlying commercial tariff is later revised.
