Strict construction of exemption notifications excluded stationary diesel engines from Notification No. 75/86, while the limitation challenge also failed.

An exemption notification was construed strictly and confined to the goods and uses expressly covered by its terms. Stationary diesel-operated internal combustion engines were held outside Notification No. 75/86 because the main exemption, read with its proviso, was limited to motor vehicles, tractors, trailers and related internal combustion engines used as original equipment; the proviso could not expand coverage to unrelated stationary engines. On limitation, a demand confirmed under Chapter X read with Rule 196 was held not to attract the extended limitation under the proviso to Section 11A, so the limitation objection failed. The duty and penalty order was upheld.

Issues: (i) Whether stationary diesel-operated internal combustion engines were covered by Notification No. 75/86 for the purpose of exemption on parts and accessories used as original equipment; (ii) Whether the demand was barred by limitation when confirmed under Rule 196 of the Central Excise Rules, 1944.

Issue (i): Whether stationary diesel-operated internal combustion engines were covered by Notification No. 75/86 for the purpose of exemption on parts and accessories used as original equipment.

Analysis: The notification exempted specified parts and accessories only when intended for use as original equipment in the manufacture of the goods described in its proviso. The opening portion referred to motor vehicles, tractors and trailers, while clause (a) of the proviso covered internal combustion engines falling under Chapter 84 only in the context of such vehicle-related equipment. The proviso could not enlarge the main exemption so as to include stationary internal combustion engines unrelated to motor vehicles, tractors or trailers. Exemption notifications are to be strictly construed at the stage of determining coverage.

Conclusion: Stationary diesel-operated internal combustion engines were not covered by the exemption, and the claim failed.

Issue (ii): Whether the demand was barred by limitation when confirmed under Rule 196 of the Central Excise Rules, 1944.

Analysis: The demand was confirmed under Chapter X read with Rule 196, and for such a demand the extended limitation under the proviso to Section 11A of the Central Excises and Salt Act, 1944 was held inapplicable. The Tribunal accepted the Revenue's submission that the limitation objection could not be sustained in this proceeding.

Conclusion: The demand was not barred by limitation.

Final Conclusion: The appeal failed on both merits and limitation, and the order confirming duty and penalty was upheld.

Ratio Decidendi: An exemption notification must be strictly confined to the goods and uses clearly brought within its terms, and a proviso cannot be used to enlarge the main exemption beyond its plain scope.
