Extended excise limitation requires proof of suppression or intent to evade; mere wrong claim cannot sustain penalties.

Extended limitation under the proviso to Section 11A(1) of the Central Excise Act applies only where the Department proves fraud, collusion, willful misstatement, suppression of facts, or other contravention with intent to evade duty. The same culpable conduct is relevant for interest and penalty under Sections 11AB and 11AC. On the facts discussed, disclosure of the manufacturing inputs, payment at the declared rate, and absence of clear evidence of deliberate concealment showed that a mere technical dispute, wrong claim, or short payment on disclosed facts is not enough to justify the extended period or consequential penal demand.

Issues: Whether the extended period under the proviso to Section 11A(1) of the Central Excise Act, 1944 could be invoked, and whether the consequential demand of duty, interest and penalty could be sustained, in the absence of deliberate suppression, fraud or intent to evade duty.

Analysis: The demand notice was issued beyond the normal period, so the Department had to establish the conditions stated in the proviso to Section 11A(1). The same condition of fraud, collusion, willful misstatement, suppression of facts or contravention with intent to evade duty governed the levy of interest under Section 11AB and penalty under Section 11AC. The record showed disclosure by the assessee of the use of PVC pipes and filters in manufacture of Tara handpumps, payment of duty at the declared rate, and no clear finding by the early adjudication that there was deliberate concealment. The later authorities treated the matter as a technical dispute or wrong claim, but did not establish conscious and deliberate evasion. Mere short payment or a misconceived claim, without proof of intent to evade, was held insufficient to attract the extended limitation and the penal consequences.

Conclusion: The extended period of limitation was not available to the Revenue, and the sustained demand of differential duty with consequential interest and penalty could not stand.

Final Conclusion: The writ petition succeeded, and the order sustaining the longer-period demand was set aside.

Ratio Decidendi: The proviso to Section 11A(1), and the connected provisions for interest and penalty, apply only when the Department proves deliberate suppression or similar culpable conduct with intent to evade duty; a mere technical breach, wrong claim, or short payment on disclosed facts is not enough.
