Excise assessment and revision powers upheld in principle, but denial of personal hearing vitiated the revisional order.

The excise rule-making and assessment scheme was upheld because the charging provision remained in the Act, the rules operated only to regulate collection and assessment, and the statutory framework provided sufficient guidance and parliamentary control; the challenge of excessive delegation therefore failed. The assessment procedure and allied rules were also found not to impose an unreasonable restriction on trade or deny a fair opportunity of hearing, given the quasi-judicial structure, appeal and revision remedies, and provisional assessment mechanisms. However, the revisional order was vitiated because the assessee was denied personal hearing on disputed questions of fact and law, and a written submission opportunity was insufficient; the impugned orders were set aside and remanded for fresh consideration.

Issues: (i) whether the rule-making and assessment scheme under the excise law amounted to excessive delegation or legislative abdication; (ii) whether the assessment procedure and allied rules imposed an unreasonable restriction on trade or denied a reasonable opportunity of being heard; and (iii) whether the revision order could stand when the assessee was denied personal hearing.

Issue (i): whether the rule-making and assessment scheme under the excise law amounted to excessive delegation or legislative abdication.

Analysis: The charging provision fixed the levy in the Act itself, while the rules only regulated collection and assessment. The statutory scheme supplied guidance through the definitions of manufacture and valuation, provided appeal and revision, and subjected the rules to parliamentary control by requiring them to be laid before Parliament with the force of law after publication.

Conclusion: The delegation was valid and the challenge on the ground of excessive delegation failed.

Issue (ii): whether the assessment procedure and allied rules imposed an unreasonable restriction on trade or denied a reasonable opportunity of being heard.

Analysis: The statutory framework contemplated a quasi-judicial approach in assessment, including summons powers, appeal, revision, provisional assessment, part-payment, and warehousing arrangements. The procedure did not compel an assessee to be heard only at the last moment, and the availability of hierarchical correction prevented arbitrary action. The rules therefore did not, in substance, impose an unreasonable restriction on trade or deny a fair opportunity at the assessment stage.

Conclusion: The challenge under the freedom of trade and fair-hearing grounds failed so far as the assessment rules were concerned.

Issue (iii): whether the revision order could stand when the assessee was denied personal hearing.

Analysis: The revisional power was quasi-judicial in character and required observance of natural justice. Where the question turned on when manufacture of the radio sets was complete, the assessee had to be given a reasonable opportunity to place its case by personal hearing and supporting material. A mere invitation to file written submissions was not sufficient compliance.

Conclusion: The refusal to grant personal hearing vitiated the revisional order and also affected the connected appellate and original orders.

Final Conclusion: The impugned excise and revisional orders were set aside and the matter was sent back for fresh appellate consideration after affording the assessee a reasonable opportunity of hearing.

Ratio Decidendi: Statutory assessment and revisional powers in fiscal matters may be validly delegated and exercised as quasi-judicial functions, but where the decision turns on disputed questions of fact and law, natural justice requires a reasonable opportunity of personal hearing before final adjudication.
