Excise short-levy demands need prior notice and effective hearing before any retrospective duty recovery or classification change.

A demand for differential excise duty cannot be sustained for an earlier period unless the assessee receives prior notice and a real opportunity to respond under the short-levy procedure. The Court treated compliance with natural justice as substantive and held that defective notice and ineffective hearing could not cure the prejudice. It also recognised that approved classification may be revisited on fresh material, including chemical test reports, but retrospective recovery is not justified on the admitted facts without lawful procedure and supporting material. Prospective action after due hearing remained open.

Issues: (i) whether a demand for differential excise duty could be sustained for the earlier period without a prior show-cause notice and meaningful opportunity of hearing under Section 11A of the Central Excises and Salt Act, 1944; (ii) whether the Assistant Collector could, on the basis of chemical test results, alter the approved classification and recover duty retrospectively, or whether such recovery could operate only prospectively and within the framework of the Act and the Rules.

Issue (i): Whether a demand for differential excise duty could be sustained for the earlier period without a prior show-cause notice and meaningful opportunity of hearing under Section 11A of the Central Excises and Salt Act, 1944.

Analysis: Section 11A requires service of notice and consideration of the assessee's representation before short-levy duty can be determined and recovered. The record showed that the initial demand was issued without complying with that procedure and that the later notices did not cure the prejudice because a real and effective opportunity to meet the material relied upon was not afforded. The requirement of natural justice in such quasi-judicial action was held to be substantive and not an empty formality.

Conclusion: The retrospective demand for the earlier period was invalid and could not be sustained.

Issue (ii): Whether the Assistant Collector could, on the basis of chemical test results, alter the approved classification and recover duty retrospectively, or whether such recovery could operate only prospectively and within the framework of the Act and the Rules.

Analysis: The Court accepted that the department was not barred from proceeding under Section 11A merely because a classification list had earlier been approved, and that the authorities could act on fresh material and test reports. However, the record did not justify an assumption that the goods had always fallen under the higher tariff entry from the beginning. On the admitted facts, a retrospective recovery from the earlier date was unsustainable, though the department could proceed afresh in accordance with law after giving proper hearing and could consider any liability from the date of the subsequent demand onwards.

Conclusion: Retrospective reassessment was not justified, but prospective action after due hearing was left open.

Final Conclusion: The writ petition succeeded only to the extent of striking down the demand for the earlier period, while leaving the departmental appeal and any lawful prospective action open for decision in accordance with law.

Ratio Decidendi: In excise recovery for alleged short levy, a demand cannot be sustained retrospectively unless the assessee is first given the notice and effective opportunity of hearing mandated by Section 11A, and approved classification cannot be altered to impose past liability without legally valid procedure and supporting material.
