Strict construction of exemption notifications and absence of wilful suppression barred extended duty demands.

Exemption under Notification No. 234/86-C.E. was confined to bulk drugs actually used for diagnosis, treatment, mitigation or prevention of disease, and the condition of being "used as such" required real pharmaceutical use; clearances to soap, cigarette, rubber, liquor and other non-pharmaceutical concerns therefore fell outside the exemption, so the demand on merits was sustained. The extended limitation period under Section 11A(1) of the Central Excise Act was unavailable because approved classification lists, gate passes and RT-12 returns disclosed the clearances and there was no proof of wilful suppression, fraud, collusion or intent to evade duty; the notices were time-barred and the extended period could not be invoked.

Issues: (i) Whether exemption under Notification No. 234/86-C.E. was available to sorbitol solution and vitamin C cleared to non-pharmaceutical concerns; (ii) Whether the show cause notices were barred by limitation and whether the extended period under Section 11A(1) of the Central Excise Act, 1944 could be invoked.

Issue (i): Whether exemption under Notification No. 234/86-C.E. was available to sorbitol solution and vitamin C cleared to non-pharmaceutical concerns.

Analysis: The notification granted exemption to bulk drugs only if they were certified by the Drugs Controller and were normally used for diagnosis, treatment, mitigation or prevention of diseases and used as such or as an ingredient in any formulation. The expression "used as such" was construed as requiring actual use in pharmaceutical or medicinal manufacture, not merely capability of such use. The certificate from the Drugs Controller did not override the substantive condition built into the notification. Since the disputed clearances were admittedly made to soap, cigarette, rubber, liquor and other non-pharmaceutical concerns, the goods in question did not satisfy the exemption conditions for those clearances.

Conclusion: Exemption was not available for the quantities cleared to non-pharmaceutical concerns, and the demand on merits was justified.

Issue (ii): Whether the show cause notices were barred by limitation and whether the extended period under Section 11A(1) of the Central Excise Act, 1944 could be invoked.

Analysis: The appellant had filed classification lists, gate passes and RT-12 returns, which were approved by the department and disclosed the nature of the goods and the consignees. The department could infer from the records that part of the clearances was to non-pharmaceutical users, and there was no material showing wilful suppression, fraud, collusion or intent to evade duty. In the absence of such ingredients, the proviso to Section 11A(1) was inapplicable and the demand had to be issued within the normal period.

Conclusion: The notices were time-barred and the extended period could not be invoked.

Final Conclusion: The appeals were allowed because the demands were barred by limitation, even though the interpretation of the exemption notification was against the assessee on merits.

Ratio Decidendi: An exemption notification must be strictly construed, and where the notification makes actual use of bulk drugs for specified pharmaceutical purposes a condition of exemption, clearances to non-pharmaceutical users fall outside the exemption; however, the extended limitation period under Section 11A(1) requires proof of wilful suppression, fraud, collusion or intent to evade duty.
