Captive-use exemption and extended limitation under central excise do not apply without factory consumption or suppression to evade duty.

An exemption confined to captive use within the factory does not extend to parts of electric motors cleared to Railway Zones for use as spare parts, because such clearances are outside factory consumption. The extended limitation period under central excise law was not sustainable on the facts, as suppression with intent to evade duty was not established; consequently, demand beyond the normal period could not survive. A second notice could not again rely on the same extended-period basis. In the absence of sustainable suppression, the penalty under Rule 173Q also fell away, leaving only the demand within the normal limitation period for quantification.

Issues: (i) Whether Notification No. 67/86-CE dated 10/02/1986 was available in respect of parts of electric motors cleared from the factory to Railway Zones for use as spare parts; (ii) Whether the demands raised by invoking the extended period under Section 11A of the Central Excise Act, 1944 were sustainable and whether the second notice could again rely on the longer limitation period; (iii) Whether penalty under Rule 173Q of the Central Excise Rules, 1944 was warranted.

Issue (i): Whether Notification No. 67/86-CE dated 10/02/1986 was available in respect of parts of electric motors cleared from the factory to Railway Zones for use as spare parts.

Analysis: The exemption covered parts of electric motors used in the factory of production as component parts in the manufacture of electric motors. The parts removed from the appellant's factory and supplied to Railway Zones were not consumed within the factory as component parts. Clearance to Railway Zones could not be treated as captive consumption for the purpose of the notification.

Conclusion: The exemption under Notification No. 67/86-CE was not available for such clearances.

Issue (ii): Whether the demands raised by invoking the extended period under Section 11A of the Central Excise Act, 1944 were sustainable and whether the second notice could again rely on the longer limitation period.

Analysis: The appellant was a unit of the Ministry of Railways, and the facts did not support an of suppression with intent to evade duty. The demand could therefore survive only within the normal limitation period. Further, once the first notice had invoked suppression for the extended period, the Department could not issue another notice again invoking the longer limitation period on the same basis.

Conclusion: The extended period was not sustainable, the demand under the first notice beyond limitation was set aside, and under the second notice only demand within the normal period could survive for quantification.

Issue (iii): Whether penalty under Rule 173Q of the Central Excise Rules, 1944 was warranted.

Analysis: In the absence of sustainable suppression and in the facts of the case, the basis for penalty did not survive.

Conclusion: The penalty was set aside.

Final Conclusion: The appeal succeeded in substantial part by setting aside the barred demand and the penalty, while leaving only the demand within the normal limitation period under the second notice to be quantified.

Ratio Decidendi: An exemption confined to goods used captively within the factory cannot be extended to clearances made outside the factory, and the extended limitation period cannot be invoked in the absence of suppression with intent to evade duty.
