Final assessment finality bars refund claims used to indirectly challenge an unappealed assessment order.

Refund was not admissible where bills of entry had been finally assessed without any exemption claim being pressed at final assessment, and the final assessment order was not challenged. The tribunal applied the principle that a refund application cannot be used to reopen or indirectly question an unappealed final assessment that has attained finality. As the importers did not seek extension of the exemption at the stage of final assessment and did not contest that order, the refund claim failed and the impugned order was sustained.

Issues: Whether refund of duty was admissible when the bill of entry had been finally assessed without a claim for exemption and the final assessment order was not challenged.

Analysis: The importers sought refund on the basis of exemption under Notification 148/94, as amended by Notification 48/96. The bills of entry had been provisionally assessed and later finally assessed, and no request was made at the time of final assessment to extend the exemption. Since the finalisation of assessment was not appealed against, the refund claim could not be used to reopen that assessment. The rule applied is that an unchallenged final assessment order cannot be indirectly questioned through a refund application.

Conclusion: The refund was not admissible and the claim failed.

Final Conclusion: The impugned order was sustained and the appeal was rejected because the final assessment had attained finality.

Ratio Decidendi: A refund claim cannot be entertained to indirectly challenge an unappealed final assessment order.
