Refinery fuel exemption upheld where fuel oil used to generate steam and power for petroleum manufacturing stayed within the manufacturing nexus.

Residual fuel oil used in a refinery to generate steam and electricity for use in manufacturing finished petroleum products was held to qualify for exemption under the relevant excise notifications, because the fuel use remained part of an integrated manufacturing process and the intervening conversion did not break the nexus with manufacture. The majority adopted a technologically realistic construction and treated fuel consumed within the refinery for production of petroleum products as covered by the exemption. A dissenting view favoured strict construction and excluded electricity-related use. The exemption claim succeeded and the assessee's appeal was allowed.

Issues: Whether residual fuel oil used in the refinery to generate steam and electricity, which in turn were used in the manufacture of finished petroleum products, qualified for exemption under the relevant excise notifications.

Analysis: The majority held that the notifications covered fuel oil used as fuel within the refinery for the production or manufacture of finished petroleum products, and that the intervening conversion into steam and electricity did not take the case outside the exemption. The use remained sufficiently connected with the manufacture of petroleum products, and a technologically realistic construction of the notifications was required. On that view, the exemption was available.

Conclusion: The issue was decided in favour of the assessee and against the Revenue.

Final Conclusion: The appeal was allowed, and the exemption claim succeeded.

Concurring/Dissenting Opinion: The dissenting member held that the notifications had to be construed strictly by their plain language, which confined exemption to petroleum products used as fuel for the manufacture of petroleum products, not electricity. Since electricity was exigible under a different tariff item, the condition of the notification was not satisfied, and the appeal should have been dismissed.

Ratio Decidendi: A refinery fuel used to generate steam and electricity for use in the manufacture of petroleum products remains fuel used within the premises for manufacture of those products when the notification language is broad enough to cover the integrated manufacturing process.
