Section 11AC penalty requires fraud or intent to evade; mere short-payment does not sustain penalty or interest.

Penalty under section 11AC of the Central Excise Act, 1944 is mandatory only after the statutory ingredients of fraud, collusion, wilful misstatement, suppression of facts, or intent to evade duty are established. The High Court noted that later Supreme Court authority did not dispense with those preconditions; it only confirmed that once they are proved, the authority has no discretion in the penalty quantum. Because the tribunal found those statutory conditions, and the related interest consequence, were not made out on the facts, the Revenue's challenge failed and the assessee's relief was maintained.

Issues: Whether penalty and interest under the Central Excise Act were leviable on the assessee on the facts found, and whether the later Supreme Court decisions displaced the tribunal's view.

Analysis: The dispute turned on the scope of section 11A, section 11AB and section 11AC of the Central Excise Act, 1944. Penalty under section 11AC is attracted only when non-payment or short-payment of duty is by reason of fraud, collusion, wilful misstatement, suppression of facts, or contravention with intent to evade duty. The Court noted that the Supreme Court authority relied on by the Revenue did not lay down that penalty follows in every case of short-payment, but only that once the statutory conditions are satisfied, the authority has no discretion in quantifying the penalty. The later Supreme Court clarification was understood to preserve the requirement that the statutory preconditions for section 11AC must first exist.

Conclusion: The tribunal's finding that the statutory conditions for penalty and interest were not established was sustained, and the Revenue's challenge failed.

Final Conclusion: The appeal was dismissed, and the assessee's relief before the tribunal remained undisturbed.

Ratio Decidendi: Penalty under section 11AC of the Central Excise Act, 1944 is mandatory only after the statutory ingredients of fraud, collusion, wilful misstatement, suppression of facts, or intent to evade duty are found to exist; absent those preconditions, neither section 11AC penalty nor the corresponding interest consequence can be sustained on mere short-payment or subsequent payment of duty.
