Section 11AC penalty requires specific fraud or suppression findings, while interest follows delayed duty as compensatory liability.

Payment of duty before issuance of a show cause notice does not by itself extinguish liability for penalty, and it does not avoid interest on belatedly paid duty because interest is compensatory. Penalty under Section 11AC of the Central Excise Act applies only where the non-levy, short-levy, short-payment, or erroneous refund is specifically linked to fraud, collusion, wilful misstatement, suppression of facts, or contravention with intent to evade duty. In the absence of such specific allegations and findings, penalty cannot be imposed mechanically, though interest remains payable on delayed duty.

Issues: (i) Whether payment of duty before issuance of show cause notice absolves the assessee from penalty and interest under the Central Excise Act, 1944. (ii) Whether penalty under Section 11AC of the Central Excise Act, 1944 could be sustained in the absence of specific allegations and findings of fraud, collusion, wilful misstatement, suppression of facts, or intent to evade duty.

Issue (i): Whether payment of duty before issuance of show cause notice absolves the assessee from penalty and interest under the Central Excise Act, 1944.

Analysis: The settled position is that payment made either before or after notice does not by itself wipe out liability for penalty where the statutory conditions for its invocation are otherwise satisfied. Interest stands on a different footing, as it is compensatory and follows delayed payment of duty.

Conclusion: Payment of duty before show cause notice does not by itself absolve liability for penalty, and it does not avoid liability for interest on belatedly paid duty.

Issue (ii): Whether penalty under Section 11AC of the Central Excise Act, 1944 could be sustained in the absence of specific allegations and findings of fraud, collusion, wilful misstatement, suppression of facts, or intent to evade duty.

Analysis: Section 11AC applies only when non-levy, short-levy, short-payment, or erroneous refund is occasioned by fraud, collusion, wilful misstatement, suppression of facts, or contravention of the Act or Rules with intent to evade duty. In the absence of a specific allegation in the notice and corresponding findings by the authorities, penalty cannot be imposed mechanically. On the interest aspect, once duty is found payable belatedly, interest follows as a compensatory consequence.

Conclusion: Penalty under Section 11AC was not sustainable on the facts, but interest on the belated duty was payable.

Final Conclusion: The challenge to penalty failed, while the challenge to interest succeeded, resulting in only partial interference with the Tribunal's order.

Ratio Decidendi: Penalty under Section 11AC is attracted only when the statutory ingredients of fraud, collusion, wilful misstatement, suppression of facts, or contravention with intent to evade duty are specifically pleaded and found, whereas interest on belated duty is compensatory and follows as a matter of course.
