Pre-notice duty payment does not automatically bar penalty or interest; statutory ingredients under the excise penalty scheme must still be proved.

Prior payment of short-levied duty before issuance of a show cause notice does not, by itself, extinguish liability to penalty or interest under the Central Excise Act where the statutory conditions involving fraud, suppression, wilful misstatement, or intent to evade duty are present. Penalty under Section 11AC can be sustained only if those factual ingredients are established on the record, and interest under Section 11AB follows the same statutory scheme. The order was found deficient because it relied only on pre-notice payment and did not examine whether the conditions for penalty were actually satisfied.

Issues: Whether payment of short-levied duty before issuance of the show cause notice absolves the assessee from penalty and interest, and whether the ingredients for penalty under Section 11AC of the Central Excise Act, 1944 were examined before imposing or setting aside the penalty.

Analysis: The statutory scheme of Sections 11AC and 11AB makes penalty and interest consequential where duty has been short-levied or short-paid on account of fraud, suppression, wilful misstatement, or contravention with intent to evade duty. Mere payment of the differential duty before issuance of the notice does not, by itself, extinguish the liability to penalty or interest. However, penalty under Section 11AC can be sustained only if the factual ingredients required by that provision are established on the record. The impugned order proceeded only on the basis that the duty had been paid before the show cause notice and did not undertake the necessary inquiry into whether the statutory conditions for penalty were satisfied.

Conclusion: Prior payment of duty before the show cause notice does not automatically erase liability to penalty or interest, but the matter required reconsideration because the statutory prerequisites for penalty under Section 11AC were not properly examined.
