Appeal allowed due to unjust enrichment bar not applying before specified date

The appellant appealed against the rejection of their refund claim based on the unjust enrichment bar. The goods were imported and provisionally assessed, leading to a refund due to the appellant. Despite the adjudicating authority directing the refund to be credited to the Consumer Welfare Fund, the appellant argued that unjust enrichment provisions were not applicable before a certain date. Supported by evidence, including a certificate from a Chartered Accountant, it was determined that the unjust enrichment bar did not apply. The appeal was allowed, granting the appellant relief.

ISSUES PRESENTED AND CONSIDERED

1. Whether the doctrine/ statutory bar of unjust enrichment applies to refunds arising from finalisation of provisional assessment under Section 18 of the Customs Act where the import and provisional assessment took place prior to 13.7.2006.

2. Whether evidence that a revenue deposit was shown in the importer's accounts as "advance recoverable" (and not charged to profit and loss) defeats the application of unjust enrichment where the refund arises on finalisation of provisional assessment.

3. Whether jurisprudence from Central Excise (amendments and decisions under the Central Excise Act) is relevant to determine the applicability of unjust enrichment under pre-13.7.2006 Customs law.

ISSUE-WISE DETAILED ANALYSIS

Issue 1: Applicability of unjust enrichment to refunds on finalisation of provisional assessment prior to 13.7.2006

Legal framework: Section 18 (pre-amendment) permits provisional assessment where documents/info/tests/enquiries are pending and provides that, on final assessment, any excess paid shall be refunded. The amended Section 18 (w.e.f. 13.7.2006) added express provisions (sub-section (5) and related interest/fund provisions) framing when refundable amounts are to be paid to the importer and incorporating language that engages the unjust enrichment concept and conditions for crediting refunds to a fund.

Precedent treatment: The High Court decision referenced (Gujarat) and the Larger Bench decision of the Tribunal held that, for imports provisionally assessed prior to 13.7.2006, refunds becoming due on finalisation were payable to the importer without a separate claim and did not attract the bar of unjust enrichment. The Tribunal has applied the same view in earlier matters.

Interpretation and reasoning: The Court examined the text of Section 18 before and after amendment. Pre-amendment Section 18(2)(a) provided for adjustment/refund on finalisation without any conditional framework addressing passing on of duty or earmarking of refunds to a fund; the post-amendment enactment introduced specific sub-sections regulating refund payment and exceptions relating to incidence of duty. Because the statutory change creating the unjust-enrichment-based bar (and related procedural safeguards) was effected only by the 13.7.2006 amendment, the Court reasoned that those limitations cannot be read back into the pre-amendment provisions. The Court therefore treated the legal position established by the cited High Court and Larger Bench authorities as controlling for the period prior to 13.7.2006.

Ratio vs. Obiter: Ratio - For provisional assessments finalised where the import and provisional assessment occurred prior to 13.7.2006, the statutory scheme did not incorporate the bar of unjust enrichment; refunds on final assessment were payable to the importer without application of that bar. Observational/obiter material - any detailed consequences of later amendments and their policy rationale (not necessary to the decision) are incidental.

Conclusion: The bar of unjust enrichment is not applicable to refunds arising from finalisation of provisional assessments where the relevant events occurred prior to 13.7.2006; such refunds are payable to the importer in accordance with pre-amendment Section 18.

Issue 2: Effect of accounting evidence (revenue deposit shown as "advance recoverable") on unjust enrichment enquiry

Legal framework: Where unjust enrichment might be relevant, an assessee's evidence that duty payments were not absorbed into landed cost or passed on to purchasers (for example, by showing the amount as an advance recoverable and not charged to profit and loss) can be material to establish absence of enrichment of the claimant's customers and thus defeat the application of the unjust enrichment bar.

Precedent treatment: The Tribunal has held that where a revenue deposit was not charged to the Profit & Loss account but reflected in the balance sheet as an advance recoverable, unjust enrichment did not operate to bar refund recovery.

Interpretation and reasoning: The appellant produced a Chartered Accountant certificate and balance-sheet entries showing the revenue deposit as recoverable, which, if relevant, would demonstrate that the importer did not pass on the incidence of the deposited duty. However, because the Court concluded that unjust enrichment was not applicable to the period in question (Issue 1), a detailed factual determination on the accounting evidence became unnecessary to the legal outcome.

Ratio vs. Obiter: Obiter - While the Court acknowledged the relevance of such accounting evidence in unjust-enrichment enquiries (and noted prior Tribunal authority supporting that position), the ultimate decision did not depend on resolving that factual/accounting point because unjust enrichment was held inapplicable as a matter of law for the period.

Conclusion: Accounting evidence showing the revenue deposit as "advance recoverable" is a recognized means to rebut unjust enrichment where that doctrine applies; but in the present case it is not decisive because unjust enrichment does not apply to pre-13.7.2006 provisional-assessment refunds.

Issue 3: Relevance of Central Excise jurisprudence (and earlier amendments) to the pre-13.7.2006 Customs position

Legal framework: Statutory amendments and judicial decisions under the Central Excise Act (e.g., changes to Section 11B) are not automatically applicable to Customs law; analysis must be anchored to the text and amendment history of the Customs Act.

Precedent treatment: A decision under the Central Excise Act relying on an amendment with effect from 20.9.1991 was cited for the proposition that unjust enrichment could apply retrospectively or in analogous circumstances. The Court evaluated that authority but distinguished it on the basis that the Customs amendment introducing the unjust-enrichment regime came into force only on 13.7.2006 and therefore the Central Excise decision did not bear on the present legal question.

Interpretation and reasoning: The Court found the Central Excise decision inapposite because it concerned a different statute and an amendment effective at a different date. The correct comparison is with the Customs Act text and its amendment timeline; absent a contemporaneous Customs amendment, the Central Excise reasoning could not be transposed to deny refunds under pre-amendment Section 18.

Ratio vs. Obiter: Ratio - Decisions under a different statutory scheme are not controlling where the statutory language and amendment dates differ materially; such decisions must be distinguished. Obiter - any broader policy parallels drawn from Central Excise jurisprudence are not determinative.

Conclusion: Central Excise precedents based on earlier or different amendments are distinguishable and not decisive for the applicability of unjust enrichment under the pre-13.7.2006 Customs statutory regime.

Overall Disposition (law applied to facts)

Because the import and provisional-assessment events occurred prior to the 13.7.2006 amendment, the statutory bar of unjust enrichment was not part of Section 18's scheme applicable to the refund at issue; authorities from the Gujarat High Court and the Tribunal's Larger Bench support this legal position; Central Excise authority relied upon by the Revenue is inapposite. The impugned order applying unjust enrichment to deny/direct the refund to a fund was set aside and the refund claim is to be allowed with consequential relief.
