Narrow reading of exemption exclusion protects captive-use gauges and templates from duty, while inconsistent Revenue positions are barred.

Notification No. 217/86-C.E. was interpreted to grant exemption for inputs manufactured and used within the same factory in or in relation to the manufacture of final products. The exclusion for machines, machinery, plant, equipment, apparatus, tools or appliances was read narrowly, applying only to items directly and immediately used in actual production or processing, not to every article used in the manufacturing process. Gauges, templates and similar captive-use items were therefore outside the exclusion and remained exempt. The Revenue was also regarded as bound by its earlier acceptance of the same interpretation in a prior Tribunal matter and could not, without explanation, take a contrary stand for a later period.

Issues: (i) Whether capital goods such as gauges, templates and similar items used captively in the manufacture of final products fell within the exclusion in Notification No. 217/86-C.E. dated 02.04.1986; (ii) whether the Revenue could take a stand inconsistent with its acceptance of an earlier Tribunal decision granting the same exemption for a prior period.

Issue (i): Whether capital goods such as gauges, templates and similar items used captively in the manufacture of final products fell within the exclusion in Notification No. 217/86-C.E. dated 02.04.1986.

Analysis: The notification exempted inputs manufactured in the factory and used within the factory in or in relation to the manufacture of final products. The dispute turned on the scope of the exclusion in the Explanation, which denied the benefit to machines, machinery, plant, equipment, apparatus, tools or appliances used for producing or processing goods or for bringing about any change in any substance. The exclusionary words were held to denote a narrower category requiring direct or immediate use in actual production or processing, and not every item that was merely used in relation to manufacture.

Conclusion: The disputed items did not fall within the exclusion and were entitled to exemption.

Issue (ii): Whether the Revenue could take a stand inconsistent with its acceptance of an earlier Tribunal decision granting the same exemption for a prior period.

Analysis: The earlier Tribunal order in favour of another assessee on the same issue had not been challenged by the Revenue. In the absence of any explanation for the differential treatment, the Revenue was held bound by the interpretation earlier accepted and could not assert a contrary position for a later period.

Conclusion: The Revenue was precluded from taking an inconsistent stand.

Final Conclusion: The exemption claim succeeded, and the Revenue's appeal failed.

Ratio Decidendi: Where an exemption notification contains both a general inclusive provision and a narrower exclusion, the exclusion must be confined to its direct and immediate scope; a tax authority cannot, without justification, adopt a contrary position after accepting the same interpretation in an earlier case on the same issue.
