Duty protest under Rule 233B fails when the approved classification list is not challenged through the statutory appeal remedy.

Rule 233B permitted duty payment under protest where the protest letter stated the grounds of dispute; a separate detailed representation was unnecessary when the reasons were already set out. However, an approved classification list was an appealable order, and once that order was not challenged, the assessee could not continue to press the protest before the Assistant Collector. The proper remedy was to file the statutory appeal against the approval order. The protest was therefore ineffective where the appeal remedy against classification approval was not pursued, and the dismissal of the protest was upheld.

Issues: (i) whether the protest against payment of duty was invalid for want of a separate detailed representation under Rule 233B of the Central Excise Rules, 1944; (ii) whether failure to appeal against the approval of the classification list barred pursuit of the protest.

Issue (i): whether the protest against payment of duty was invalid for want of a separate detailed representation under Rule 233B of the Central Excise Rules, 1944.

Analysis: Rule 233B contemplated payment under protest where duty was paid against an existing order or decision, and it also required a detailed representation where no appeal or revision was available. The protest letter already contained the reasons for disputing the classification and was not a bare protest without grounds. In that situation, insisting on another detailed representation was unnecessary.

Conclusion: The rejection of the protest on the ground of absence of a detailed representation was not sustainable.

Issue (ii): whether failure to appeal against the approval of the classification list barred pursuit of the protest.

Analysis: The approved classification list was an appealable order under Section 35 of the Central Excises and Salt Act, 1944. Once that order was not challenged, the assessee could not continue to press the protest before the Assistant Collector. The proper course was to pursue the statutory appeal against the approval order.

Conclusion: The protest could not survive the failure to file an appeal against the approval of the classification list.

Final Conclusion: The appeal failed because the assessee did not challenge the approved classification list, and the dismissal of the protest was ultimately upheld.

Ratio Decidendi: Where an approved classification list is an appealable order, a party cannot bypass the statutory appellate remedy by persisting with a protest, and a separate detailed representation is unnecessary if the protest letter itself states the grounds.
