Suppression of facts and duty quantification: non-disclosure justified extended limitation, while a later addendum was not a fresh notice.

Non-disclosure of other manufacturing units and inconsistent declarations to the excise authorities can amount to suppression of facts, allowing invocation of the extended limitation period under Section 11A for duty demand. A notice addendum that only quantifies duty for a period already covered by the original notice is not treated as a fresh show cause notice under the amended Section 11A, and the demand remains legally maintainable. On penalty, the quantum imposed under Rule 173Q may be moderated in the circumstances, while the penalty under Rule 9(2) may be sustained.

Issues: (i) whether the extended period under Section 11A could be invoked on the ground of suppression of facts in respect of the appellants' Item 68 clearances; (ii) whether the addendum quantifying duty for the later period was invalid as a fresh notice under the amended Section 11A; and (iii) whether the penalty under Rule 173Q required reduction.

Issue (i): Whether the extended period under Section 11A could be invoked on the ground of suppression of facts in respect of the appellants' Item 68 clearances.

Analysis: The appellants had not disclosed all their manufacturing units and had filed declarations containing statements inconsistent with the existence of other similar units. The notification governing exemption and licensing was clear on the aggregate clearances and the appellants were aware of their obligations, yet they did not inform the department of the other units. Mere maintenance of private records did not amount to proper disclosure to the excise authorities. The earlier Supreme Court decisions relied upon by the appellants were distinguished on facts.

Conclusion: The invocation of the extended period for demand under Section 11A was upheld, and the finding of suppression of facts stood against the assessee.

Issue (ii): Whether the addendum quantifying duty for the later period was invalid as a fresh notice under the amended Section 11A.

Analysis: The original notice had already put the appellants on notice that duty was demanded for the relevant later period and that exact quantification would follow upon receipt of particulars. The addendum merely communicated the quantified amount and did not introduce a new demand or a new cause of action. It was therefore not treated as a fresh show cause notice.

Conclusion: The addendum was held to be valid and the demand was maintainable in law.

Issue (iii): Whether the penalty under Rule 173Q required reduction.

Analysis: The penalty under Rule 9(2) was not considered excessive, but the quantum imposed under Rule 173Q was viewed as capable of moderation in the circumstances, having regard to the duty involved.

Conclusion: The penalty under Rule 173Q was reduced to Rs. 25,000, while the penalty under Rule 9(2) was maintained.

Final Conclusion: The demand and the finding of suppression were sustained, but the penalty was partially curtailed, leaving the appeal unsuccessful except for the limited reduction in penalty.

Ratio Decidendi: Non-disclosure of other manufacturing units and failure to inform the excise authorities of all relevant clearances can constitute suppression of facts warranting invocation of the extended limitation period, and a subsequent addendum that merely quantifies an already-notified demand is not a fresh show cause notice.
