Prospective excise notification and intra-factory movement rules barred fresh duty on blended yarn already consumed in manufacture.

A later excise notification was treated as prospective only and could not retrospectively impose separate duty on blended yarn already manufactured and consumed before 24.07.1972. The text also states that intra-factory movement of yarn within a continuous manufacturing process was not a separate removal attracting independent levy under the Central Excise Rules, 1944. On that basis, the demand lacked legal foundation, and adjustment of duty paid at a later stage against the same demand was described as maintainable where the same manufactured article would otherwise suffer multiple levy.

Issues: (i) Whether Notification No. 169/72 dated 24.07.1972 operated retrospectively so as to fasten separate excise duty on blended yarn manufactured and consumed before that date; (ii) whether the blended yarn, having moved within the factory for use in the continuous manufacturing process, could be treated as separately dutiable under the Central Excise Rules, 1944; (iii) whether the assessee was entitled to adjustment of any duty paid after 24.07.1972 against the demand raised on the blended yarn.

Issue (i): Whether Notification No. 169/72 dated 24.07.1972 operated retrospectively so as to fasten separate excise duty on blended yarn manufactured and consumed before that date.

Analysis: Notification No. 62/72 had placed blended yarn under the special procedure and deferred collection to the stage of fabric clearance. Notification No. 169/72 merely substituted the description of yarn in the earlier notification and did not contain any language giving it retrospective effect or undoing the position for the earlier period. The goods in question had already been manufactured and consumed before the later notification, and the demand was founded only on the later notification.

Conclusion: The later notification was prospective only, and the demand for separate duty on yarn manufactured and consumed before 24.07.1972 was not sustainable.

Issue (ii): Whether the blended yarn, having moved within the factory for use in the continuous manufacturing process, could be treated as separately dutiable under the Central Excise Rules, 1944.

Analysis: The explanations to Rules 9 and 49 treated movement of goods within the factory for a continuous process as removal from the factory. On the admitted facts, the blended yarn was manufactured and consumed within the factory before 24.07.1972, and the authorities failed to apply these provisions. The levy therefore lacked legal foundation.

Conclusion: The yarn was not separately dutiable on the facts found, and the impugned demand could not be upheld.

Issue (iii): Whether the assessee was entitled to adjustment of any duty paid after 24.07.1972 against the demand raised on the blended yarn.

Analysis: The claim for adjustment raised a pure legal question on undisputed facts. The revisional authority ought to have examined it, and in any event the scheme did not contemplate multiple levy on the same manufactured article. If duty had already been paid at a higher stage, adjustment should have been considered.

Conclusion: The assessee's claim for adjustment was maintainable and should not have been rejected on the stated ground.

Final Conclusion: The excise demand and the orders affirming it were without authority of law and were quashed, with the writ petition allowed.

Ratio Decidendi: A later excise notification that is prospective in terms cannot retrospectively create a fresh liability for goods already manufactured and consumed under an earlier exemption or special procedure, and levy cannot be sustained where the statutory rules treat intra-factory movement in a continuous process as non-separate removal.
