Manufacture and excise exemption principles applied to pigment slurry, nitrocellulose lacquer, and retrospective validation of excise rules.

Manufacture under central excise requires emergence of a commercially distinct article with a different name, character or use, so pigment slurry made by mixing pigment powder with solvent and used captively in leather manufacture was not excisable. Nitrocellulose lacquer was treated as a distinct manufactured product and therefore dutiable, but the exemption under Notification No. 80/80 applied because only lacquer clearances were relevant for the prescribed value limit and the value of finished leather could not be clubbed. Retrospective validation of the amended excise rules was upheld, and the writ was not barred by alternative remedy where constitutional validity was in issue and duty had been paid under protest.

Issues: (i) whether pigment slurry manufactured by mixing pigment powders with solvents and used captively in the manufacture of finished leather was excisable and liable to duty under the relevant tariff entry; (ii) whether nitrocellulose lacquer was excisable but exempt under Notification No. 80/80 because its clearances did not exceed the prescribed value limit; (iii) whether Section 51 of the Finance Act, 1982 and the retrospective amendment of Rules 9 and 49 of the Central Excise Rules, 1944 were valid; and (iv) whether the writ petition was barred by availability of an alternative remedy.

Issue (i): whether pigment slurry manufactured by mixing pigment powders with solvents and used captively in the manufacture of finished leather was excisable and liable to duty under the relevant tariff entry.

Analysis: Manufacture under the Central Excises and Salt Act, 1944 requires emergence of a new and distinct commodity having a different name, character or use. Pigment slurry was found to be only pigment powder in wet form, with its chemical properties remaining unchanged, and it did not become a commercially distinct product. The burden to establish excisability lay on the taxing authority, and that burden was not discharged. The slurry therefore did not answer the description of water pigment finishes for leather.

Conclusion: The levy of duty on pigment slurry was unsustainable and the assessee succeeded on this issue.

Issue (ii): whether nitrocellulose lacquer was excisable but exempt under Notification No. 80/80 because its clearances did not exceed the prescribed value limit.

Analysis: Nitrocellulose lacquer was held to be a manufactured product distinct from its inputs and therefore dutiable under the relevant tariff entry. However, for the purpose of Notification No. 80/80, the value of the lacquer clearances alone was to be considered, and the exempt finished leather could not be clubbed to deny the exemption. Since the value of lacquer clearances was below the prescribed limit, the exemption applied.

Conclusion: Although nitrocellulose lacquer was excisable, no duty was payable on it under Notification No. 80/80, and the assessee succeeded on this issue.

Issue (iii): whether Section 51 of the Finance Act, 1982 and the retrospective amendment of Rules 9 and 49 of the Central Excise Rules, 1944 were valid.

Analysis: Retrospective operation of fiscal legislation is not unconstitutional merely because it is retrospective. The court found no unreasonable or arbitrary burden flowing from the amendment, and the retrospective validation of the amended rules did not offend the constitutional challenge raised.

Conclusion: The challenge to Section 51 of the Finance Act, 1982 and the retrospective amendment of Rules 9 and 49 failed.

Issue (iv): whether the writ petition was barred by availability of an alternative remedy.

Analysis: The petition had already been entertained, the duty had been paid under protest, and the challenge included the constitutional validity of the retrospective provision and notification, matters not effectively redressable in the suggested appellate remedy. The objection based on alternative remedy was therefore rejected.

Conclusion: The alternative remedy objection failed.

Final Conclusion: The petition was allowed in part, the duty demand on pigment slurry was set aside, the duty paid on nitrocellulose lacquer was held refundable under the exemption notification, and the constitutional challenge to the retrospective validating provision did not succeed.

Ratio Decidendi: A process amounts to manufacture only when it produces a commercially distinct article with a different name, character or use, and a fiscal exemption is to be applied on the basis of the clearances of the exempted product itself unless the notification expressly requires aggregation of unrelated exempt goods.
