Amended exemption conditions and disclosure failures can defeat excise relief, sustain demand, and uphold penalty.

Amended exemption notifications can introduce fresh disqualifying conditions and a new method for computing aggregate clearances, and continued exemption must be established under the amended regime; prior approval is not enough. On the facts, the manufacturer's clearances under multiple tariff items crossed the revised threshold and the required fresh declaration was not made, so exemption was denied. The demand and penalty were upheld because the excise recovery provisions were treated as permitting action where the changed facts were not properly disclosed, and the longer limitation period applied. A separate exemption claim failed because the product contained vitamins regarded as active therapeutic agents rather than inert pharmaceutical necessities.

Issues: (i) whether the appellant remained entitled to the exemption under Notification No. 71/78-C.E. after the amendment introduced by Notification No. 141/79-C.E. and its successor notification, and whether the clearances of goods falling under more than one tariff item crossed the prescribed disqualifying limit; (ii) whether the demand of duty and penalty under Rule 9(2) and Rule 173Q were invalid because the Collector lacked power to determine the duty, or because the notice was time-barred; (iii) whether Piyamycetine Vet was wrongly claimed as exempt under Notification No. 116/69-C.E.

Issue (i): whether the appellant remained entitled to the exemption under Notification No. 71/78-C.E. after the amendment introduced by Notification No. 141/79-C.E. and its successor notification, and whether the clearances of goods falling under more than one tariff item crossed the prescribed disqualifying limit

Analysis: The amended notification introduced an additional disqualifying condition for manufacturers clearing goods under more than one tariff item and also inserted an explanation for computing aggregate clearances. The appellant had manufactured goods under Tariff Item 14E and Tariff Item 68, and the Tribunal found that the amended conditions had materially altered the basis of entitlement. The explanation excluded only specified goods totally exempted by another notification, and the appellant's goods did not bring it within that exclusion. The appellant had not made the fresh declaration required after the amendment, and its continued reliance on the earlier position was not accepted.

Conclusion: The exemption was not available to the appellant, and the denial of the concession was upheld.

Issue (ii): whether the demand of duty and penalty under Rule 9(2) and Rule 173Q were invalid because the Collector lacked power to determine the duty, or because the notice was time-barred

Analysis: The incorporation of Section 11A into Rule 9(2) was treated as a limitation on the time for issuing the demand, not as importing the entire procedure of Section 11A or restricting action only to the Assistant Collector. The Tribunal held that the Collector's order confirming the short levy was competent. On limitation, the Tribunal held that the appellant had failed to make a proper declaration in the changed circumstances, and the longer period was attracted because the relevant facts had not been fully and properly disclosed for the purpose of the exemption claim.

Conclusion: The demand and penalty were valid, and the objection on competence and limitation failed.

Issue (iii): whether Piyamycetine Vet was wrongly claimed as exempt under Notification No. 116/69-C.E.

Analysis: The notification exempted medicines meeting specified ingredient requirements and permitted only therapeutically inert pharmaceutical necessities. The vitamins contained in the product were held to be active therapeutic agents, not inert excipients or pharmaceutical necessities of the kind contemplated by the notification. The appellant's challenge to the exclusion from exemption was rejected.

Conclusion: The product was not entitled to exemption under Notification No. 116/69-C.E.

Final Conclusion: The appellate challenge failed in full, and the duty demand and penalty sustained by the Collector were maintained.

Ratio Decidendi: When an exemption notification is amended so as to impose new disqualifying conditions and a fresh basis for computing aggregate clearances, a manufacturer must positively establish continued eligibility under the amended regime; exemption cannot be assumed from prior approval, and non-disclosure of the changed position can attract demand and penalty under the excise recovery provisions.
