Refund claims after duty paid under protest require fresh examination of assessment challenge, exemption entitlement, and unjust enrichment.

Payment of duty under protest was treated as a sufficient challenge to the Bill of Entry assessment for refund purposes, so a separate appeal against the assessment was not required. The Tribunal noted that the refund could not be rejected on a fresh appellate ground that had not formed part of the original adjudication. It also recorded that the exemption under Notification No. 29/97-Cus. had been accepted in the assessee's earlier case, and that the questions of exemption entitlement and unjust enrichment required fresh consideration.

Issues: Whether the refund claim could be rejected on the ground that the assessment of the Bill of Entry had not been challenged, when the duty had been paid under protest, and whether the matter required reconsideration on the merits of the exemption claim and unjust enrichment.

Analysis: The Bill of Entry was assessed to CVD at 10%, but the duty payment was expressly endorsed as made under protest. That endorsement was treated as a challenge to the assessment itself, so a separate challenge to the Bill of Entry assessment was not necessary before seeking refund. The Tribunal also noted that the benefit of Notification No. 29/97-Cus. had been allowed in the appellant's own earlier case on the same issue. The appellate authority could not introduce a new ground to reject the refund claim when that ground had not formed part of the original adjudication, and the question of passing on the duty incidence also required examination.

Conclusion: The rejection of refund on the ground of challenge to assessment was not sustained, and the matter was required to be reconsidered afresh.

Final Conclusion: The assessee succeeded and the refund dispute was sent back for fresh adjudication on the exemption and unjust enrichment issues.

Ratio Decidendi: Payment of duty under protest constitutes a challenge to the assessment for refund purposes, and a new appellate ground cannot be used to sustain rejection of refund where it was not part of the original adjudication.
