Extended limitation under Central Excise law requires proof of suppression or wilful misstatement; full disclosure defeats it.

Extended limitation under the proviso to Section 11A of the Central Excise Act could be invoked only on proof of the statutory exceptions, including material suppression or wilful misstatement. Where the assessee had disclosed the manufacturing process, answered departmental queries, and the classification dispute was already a live issue, the Revenue could not rely on the proviso merely because the legal position was clarified later in prior decisions. On those facts, the extended period was inapplicable, the demand was time-barred, and the appeal failed.

Issues: Whether the extended period of limitation under the proviso to Section 11A of the Central Excise Act, 1944 could be invoked on the facts of the case.

Analysis: The assessee had disclosed the manufacturing process and responded to departmental queries, and the classification issue regarding decorative laminated sheets was already a live question in the field. The Court held that invocation of the proviso required the Revenue to establish the statutory conditions for the exceptional extended period, including material suppression or wilful misstatement, and that such a case was not made out where the relevant facts had been disclosed and accepted by the department. The notice was also issued after the legal position on classification had been clarified in earlier decisions, which did not by itself justify the extended limitation.

Conclusion: The extended period of limitation was not applicable, and the demand was time-barred. The appeal failed.

Ratio Decidendi: The extended period under the proviso to Section 11A can be invoked only on proof of the statutory grounds for the exception, and not where the assessee has made full disclosure of the material facts and no wilful suppression or misstatement is established.
