Approved price lists and repeal of Rule 10 shape short-levy demands, while yarn duty remains includible in fabric valuation.

Approved price lists could not support a short-levy demand unless they were lawfully revised or modified; demands raised directly on unaltered approved lists were not enforceable. Proceedings validly started under Rule 10 before its repeal could continue, but a notice issued after repeal could not derive validity from the repealed rule and was invalid for that reason. Duty paid on yarn under the compounded levy scheme was includible in the assessable value of fabrics manufactured from that yarn, as the scheme did not create an exemption or amount to double taxation. The demands were ultimately set aside, although the yarn duty remained part of valuation.

Issues: (i) Whether demands for alleged short levy could be sustained without first revising or modifying the approved price lists; (ii) whether proceedings initiated under Rule 10 survived the repeal of that rule; and (iii) whether the duty paid on yarn was includible in the assessable value of fabrics.

Issue (i): Whether demands for alleged short levy could be sustained without first revising or modifying the approved price lists.

Analysis: The price lists had been approved without including yarn duty, and they were never revised or modified in the manner prescribed by the rules. The show cause notices did not seek modification of the approved price lists but directly demanded differential duty for an earlier period. A demand for short levy could not be enforced while the approved lists continued to operate, and the notices were not valid as notices for alteration of the approved valuation.

Conclusion: In favour of the assessee. The demands based on the unmodified approved price lists were not sustainable.

Issue (ii): Whether proceedings initiated under Rule 10 survived the repeal of that rule.

Analysis: Proceedings validly initiated while Rule 10 was in force could continue notwithstanding its later repeal. However, a notice issued after the repeal could not derive validity from a repealed rule. On that basis, the notices issued before repeal were not defeated merely by the repeal, while the notice issued after repeal was not valid under Rule 10.

Conclusion: In favour of the assessee in respect of the post-repeal notice. Proceedings under the earlier notices were not extinguished by repeal, but the notice issued after repeal was invalid.

Issue (iii): Whether the duty paid on yarn was includible in the assessable value of fabrics.

Analysis: Duty paid on yarn under the compounded levy arrangement formed part of the value of the fabrics manufactured from that yarn. Collection of duty at the fabric stage did not prevent inclusion of the yarn duty in the assessable value. The scheme was one of convenience and did not amount to exemption or double taxation.

Conclusion: Against the assessee. Yarn duty was includible in the assessable value of the fabrics.

Final Conclusion: The appeals succeeded because the impugned demands were set aside for want of enforceability, even though the duty on yarn was otherwise includible in the assessable value of the fabrics.

Ratio Decidendi: A demand for short levy cannot be enforced on the basis of approved price lists that have not been lawfully revised, and the repeal of a rule does not validate a post-repeal notice issued under that rule, though duty paid on yarn may still form part of the assessable value of the resultant fabrics.
