Issues Involved:
1. Whether the Tribunal erred in following the judgment in Scientific Instruments, which is per incuriam the judgments of the Supreme Court in Mafatlal and Allied Photographics.
2. Applicability of Section 18(5) of the Customs Act post-amendment to refund claims made prior to 13.07.2006.
3. Legitimacy of remanding the issue for examining unjust enrichment in light of Supreme Court and High Court judgments.

Detailed Analysis:

Issue 1: Tribunal’s Reliance on Scientific Instruments Judgment
The primary contention was whether the Tribunal erred in following the judgment in Scientific Instruments, which allegedly overlooked the Supreme Court judgments in Mafatlal and Allied Photographics. The Tribunal had relied on the decision in Scientific Instruments, which held that the test of unjust enrichment applies to provisional assessments followed by final assessments, even if the refund claim was made prior to the insertion of Section 18(5) of the Customs Act. The High Court upheld this reliance, noting that the Tribunal followed judicial discipline by adhering to the precedent set by the High Court in Scientific Instruments.

Issue 2: Applicability of Section 18(5) Post-Amendment
The appellant argued that Section 18(5) of the Customs Act, which mandates the examination of unjust enrichment, should not apply to refund claims made before its insertion on 13.07.2006. The Court examined the provision and concluded that the principle of unjust enrichment is inherent in the refund process, irrespective of the specific date of the amendment. The Court referred to the Supreme Court’s decision in Mafatlal, which emphasized that refund claims are subject to proof of not passing on the duty burden to others. Thus, the Court held that the principle of unjust enrichment applies to all refund claims, even those made before the amendment.

Issue 3: Legitimacy of Remanding for Unjust Enrichment Examination
The appellant contended that the Commissioner (Appeals) should not have remanded the matter to the original authority to examine unjust enrichment, as this was only applicable post-13.07.2006. The Court disagreed, stating that the final assessment of duty inherently involves examining whether the duty burden was passed on. The Court cited Section 18(2) of the Customs Act, which requires final assessment before a refund is considered, and noted that unjust enrichment must be evaluated to ensure the importer has not passed on the duty burden. The Court supported the remand, affirming that the original authority must verify unjust enrichment before granting refunds.

Conclusion:
The High Court upheld the Tribunal’s decision, confirming that the principle of unjust enrichment applies to all refund claims, regardless of when they were made. The Court emphasized that final assessments must include an examination of unjust enrichment to prevent undue benefits. The appeals were dismissed, and the Tribunal’s order was sustained, affirming the remand for examining unjust enrichment. The substantial questions of law were answered against the appellant and in favor of the Revenue.
