Customs refund cannot reopen a final Bill of Entry assessment unless the assessment is first challenged

A refund claim under customs law cannot be used to reopen a Bill of Entry assessment that has attained finality unless that assessment was first challenged or otherwise modified. The majority held that the refund authority lacks power to revisit a concluded assessment in refund proceedings, and that Section 154 of the Customs Act is limited to clerical, arithmetical, accidental slip or omission errors. It does not extend to undoing a conscious assessment said to have been made without applying an exemption notification. On that basis, the refund route was held unavailable where the assessment itself remained unchallenged.

Issues: Whether a refund claim is maintainable without first challenging the assessment of the Bill of Entry.

Analysis: The majority held that once an assessment of the Bill of Entry has attained finality and has not been appealed against or otherwise modified, the refund authority cannot reopen that assessment in refund proceedings. The scope of rectification under Section 154 of the Customs Act, 1962 was held to be confined to clerical, arithmetical, accidental slip or omission type errors, and not to cases where the assessee seeks to undo a conscious assessment allegedly made without extending an exemption notification. On that reasoning, the assessment could not be treated as corrigible through the refund route.

Conclusion: The refund claim was not maintainable without challenging the assessment of the Bill of Entry, and the issue was answered against the assessee.
