Captive-consumption exemption and limitation principles governed DMT-residue duty demand, with penalty also falling away.

Extended limitation could not be invoked where the assessee had disclosed the emergence and use of DMT-residue to the department, sought licensing guidance, and the department knew the manner of utilisation; absence of suppression, fraud, misstatement or wilful contravention made the earlier demand time-barred. For the later period, DMT-residue used within the factory as fuel to generate steam for manufacture fell within captive-consumption exemption under Notification No. 217/86-C.E. and Notification No. 67/95-C.E., with the demand also treated as revenue neutral because duty paid on residue could have been available as credit. As the demand failed, no penalty survived.

Issues: (i) whether the demand for the period 1-3-1986 to 31-3-1990 was barred by limitation; (ii) whether the assessee was entitled to exemption for captive consumption under Notification No. 217/86-C.E. and Notification No. 67/95-C.E. for the later period, with the consequence for penalty.

Issue (i): whether the demand for the period 1-3-1986 to 31-3-1990 was barred by limitation

Analysis: The assessee had disclosed the emergence of DMT-residue to the department in 1985, sought guidance on licensing, obtained the licence, and the department had knowledge of the manner in which the residue was being used. On these facts, the ingredients necessary for invocation of the extended period, namely suppression, fraud, misstatement or wilful contravention with intent to evade duty, were absent.

Conclusion: The demand for 1-3-1986 to 31-3-1990 was barred by limitation and was unsustainable.

Issue (ii): whether the assessee was entitled to exemption for captive consumption under Notification No. 217/86-C.E. and Notification No. 67/95-C.E. for the later period, with the consequence for penalty

Analysis: DMT-residue was used within the factory as fuel for generating steam in the boiler, which was in turn used in manufacture of the final product. The exemption notifications covered captive consumption of inputs used in the manufacture of final products within the factory. The assessee was therefore entitled to the benefit of the exemption notifications for the relevant later period. The Tribunal also accepted the revenue-neutral character of the demand because duty paid on the residue could have been available as credit for payment of duty on DMT. As the demand itself failed, no penalty could survive.

Conclusion: The assessee was entitled to the exemption for the later period, and the penalties were not warranted.

Final Conclusion: The appeal succeeded on limitation and exemption, the demand was set aside, and the assessee obtained consequential relief.
