Declared goods treatment for unmachined cast iron castings upheld; constitutional challenge to the sales tax proviso failed.

Unmachined cast iron castings were treated as declared goods under section 14 of the Central Sales Tax Act and the Fourth Schedule, because the distinction between rough castings and finished machined products did not justify classifying them as unclassified goods under section 5(1) of the Karnataka Sales Tax Act. The assessment treating those sales at a higher or unclassified rate was therefore unsustainable. The constitutional challenge to the proviso inserted into section 5(1) by Act No. 18 of 1994 was rejected, as the provision could be construed consistently with the statutory scheme rather than struck down as ultra vires.

Issues: (i) Whether unmachined cast iron castings were declared goods liable to tax at the concessional rate and not as unclassified goods under section 5(1) of the Karnataka Sales Tax Act; (ii) Whether the proviso inserted to section 5(1) of the Karnataka Sales Tax Act by Act No. 18 of 1994 was unconstitutional.

Issue (i): Whether unmachined cast iron castings were declared goods liable to tax at the concessional rate and not as unclassified goods under section 5(1) of the Karnataka Sales Tax Act.

Analysis: The dispute was resolved by applying the scope of section 14 of the Central Sales Tax Act, 1956 and the earlier binding interpretation that rough or unmachined cast iron castings are covered by the expression "cast iron" and therefore fall within declared goods. The distinction drawn in the case law between rough castings on the one hand and finished machined products on the other was material. Since the proviso did not distinguish between machined and unmachined castings, the assessment could not treat unmachined cast iron castings as an unclassified commodity or tax them under section 5(1). They had to be treated as declared goods under the Fourth Schedule.

Conclusion: The sales of unmachined cast iron castings were required to be assessed as declared goods at the concessional rate, and the assessment to the contrary was unsustainable.

Issue (ii): Whether the proviso inserted to section 5(1) of the Karnataka Sales Tax Act by Act No. 18 of 1994 was unconstitutional.

Analysis: The proviso was examined in the light of the statutory scheme governing declared goods and the earlier decisions on the distinction between cast iron castings and finished cast products. On that interpretation, the Court found no necessity to strike down the proviso as ultra vires, since the controversy could be resolved by construing the provision consistently with the treatment of unmachined cast iron castings as declared goods.

Conclusion: The challenge to the proviso as unconstitutional was rejected.

Final Conclusion: The assessment orders were quashed to the extent they treated unmachined cast iron castings as taxable under section 5(1), but the constitutional challenge to the proviso failed; the petition succeeded only to that limited extent.

Ratio Decidendi: Unmachined cast iron castings fall within declared goods under the Central Sales Tax Act and cannot be subjected to a higher or unclassified tax treatment inconsistent with that status, while a constitutional challenge to a proviso need not succeed where the provision can be validly construed in harmony with the statutory scheme.
