Natural justice in classification list modification requires notice and hearing before any prejudicial excise determination.

Rule 173-B required the proper officer to conduct the contemplated enquiry and give the assessee a meaningful opportunity of hearing before modifying a classification list or making any prejudicial determination. The approval stage formed part of assessment, so refusal to issue notice on the footing that none was needed offended natural justice. The impugned order was therefore unsustainable and had to be set aside, with the matter remitted for fresh decision after notice and hearing.

Issues: Whether the Assistant Collector could modify the classification list under Rule 173-B of the Central Excise Rules, 1944 without issuing notice and granting an opportunity of hearing, and whether the impugned endorsement and order were sustainable.

Analysis: Rule 173-B contemplates approval of the classification list by the proper officer after such enquiry as he deems fit and with such modifications as are considered necessary. The approval of the classification list is an important stage in the assessment process, and before the duty is quantified or any order prejudicial to the assessee is made, a meaningful enquiry and an opportunity of being heard are required. The refusal to hear the assessee on the footing that no notice was necessary ignored the scope of the rule and offended the principles of natural justice.

Conclusion: The enquiry and hearing under Rule 173-B were mandatory, and the impugned order could not stand. The petition succeeded, the order was set aside, and the matter was sent back for fresh decision after issuing notice and hearing the petitioner.

Ratio Decidendi: Where a classification list is to be modified under Rule 173-B of the Central Excise Rules, 1944, the proper officer must conduct the contemplated enquiry and afford the assessee an opportunity of being heard before making any prejudicial determination.
