Limitation, natural justice, and restricted electricity use preserved excise exemption and defeated duty demand

A later excise notice based on the same material already known to the department could not justify invocation of the extended limitation period, so the demand was time-barred. The adjudication was also vitiated by breach of natural justice because relied-upon documents were not supplied, documents were retained, and effective hearing and cross-examination were denied. On exemption, limited use of electricity for heating moulding powder or moulds, and for buffing, polishing, or testing, did not defeat the notification where moulding remained hand operated and no electric motor was used in the moulding process itself. The duty demand, penalty, and confiscation therefore could not survive.

Issues: (i) Whether the demand proceedings were barred by limitation and whether the second notice could be sustained on the same material; (ii) Whether denial of relied upon documents, non-return of documents, and denial of effective hearing and cross-examination vitiated the adjudication for breach of natural justice; (iii) Whether the assessee was entitled to exemption under the relevant notification despite use of electricity for heating the moulding powder and buffing operations.

Issue (i): Whether the demand proceedings were barred by limitation and whether the second notice could be sustained on the same material.

Analysis: The subsequent notice proceeded on the same facts and material already within the department's knowledge in the earlier proceedings. On that footing, invocation of the extended period for the past demand was unsustainable, since the department could not treat the later notice as an independent basis to revive time-barred demands.

Conclusion: The limitation objection succeeded in favour of the assessee.

Issue (ii): Whether denial of relied upon documents, non-return of documents, and denial of effective hearing and cross-examination vitiated the adjudication for breach of natural justice.

Analysis: The record showed prejudice from non-supply of relied upon documents in the later proceedings, retention of non-relied upon documents, absence of an effective personal hearing, and denial of cross-examination. These defects materially impaired the assessee's ability to defend the notice and amounted to violation of natural justice.

Conclusion: The adjudication was vitiated for breach of natural justice in favour of the assessee.

Issue (iii): Whether the assessee was entitled to exemption under the relevant notification despite use of electricity for heating the moulding powder and buffing operations.

Analysis: The notification conditions were treated as satisfied where moulding remained hand operated, electricity was used only for heating the moulds or powder before moulding, and power was used for buffing or polishing and testing as permitted. The technical certificate supported the claim that no electric motor was used for the moulding process itself, and the Board's circular on the predecessor notification was followed to hold that such limited power use did not forfeit the exemption.

Conclusion: The exemption was allowable and the denial of benefit was not upheld.

Final Conclusion: The duty demand, penalty, and confiscation could not survive because the proceedings were time-barred, procedurally unfair, and unsustainable on the merits of exemption eligibility.

Ratio Decidendi: Where a later excise notice rests on the same known material as earlier proceedings, the extended period cannot be invoked; and limited use of electricity only for heating the moulds or powder before moulding does not by itself defeat an exemption conditioned on hand-operated manufacture and restricted use of power.
