Validation provisions and captive yarn duty: limitation relief survived, and duty applied on unsized weight before sizing.

Section 51 of the Finance Act, 1982 was treated as a validating provision for captive consumption levies and retrospective amendments to Rules 9 and 49, but it did not expressly withdraw the limitation-based relief earlier granted, so that relief remained effective. In an integrated spinning-and-weaving process, sizing was regarded as a preparatory step in weaving, and the Tribunal followed the consistent High Court view that excise duty on yarn is chargeable on the unsized weight before sizing, not on the sized weight. On that basis, the impugned order was unsustainable and consequential refund was allowed.

Issues: (i) whether Section 51 of the Finance Act, 1982 nullified the partial relief earlier granted on limitation under Rule 9(2) of the Central Excise Rules; (ii) whether duty on yarn used captively in an integrated weaving process was leviable on the sized weight or the unsized weight of the yarn.

Issue (i): whether Section 51 of the Finance Act, 1982 nullified the partial relief earlier granted on limitation under Rule 9(2) of the Central Excise Rules.

Analysis: Section 51 was treated as a validating provision intended to regularise the duty levy on deemed removals for captive consumption and to give retrospective effect to the amendments to Rules 9 and 49. The partial relief earlier granted on limitation was not reviewed by the competent authority, and nothing in Section 51 was found to withdraw that relief.

Conclusion: The earlier limitation relief remained effective and could not be treated as having been voided by Section 51.

Issue (ii): whether duty on yarn used captively in an integrated weaving process was leviable on the sized weight or the unsized weight of the yarn.

Analysis: The levy was examined in the context of the integrated process of spinning yarn and weaving fabrics, with sizing treated as a preparatory process in weaving. The Tribunal relied on the consistent view taken by the High Courts that, in such a process, duty is chargeable on the yarn before sizing, that is, on the unsized weight.

Conclusion: Duty was payable on the unsized weight of the yarn, not on the sized weight.

Final Conclusion: The impugned order could not be sustained, and the assessee was entitled to the consequential refund claimed.

Ratio Decidendi: Where a validating provision does not expressly withdraw a limitation-based relief already granted and the manufacturing activity is an integrated spinning-and-weaving process, excise duty on yarn is to be assessed on the unsized weight before sizing.
