Turnover-based additional sales tax and anti-passing-on rules upheld as rational, constitutionally valid taxation measures.

An additional sales tax on dealers with turnover above a prescribed limit was treated as sales tax in substance and upheld as a rational turnover-based classification, as larger dealers were regarded as a distinct class with greater capacity to bear tax; the levy was therefore not found to violate Articles 14 or 19(1)(g). The proviso limiting tax on declared goods was read consistently with section 15(a) of the Central Sales Tax Act, 1956, because the principal tax and additional tax had to be read together within the statutory ceiling. Provisions prohibiting collection of the tax, along with the penal and rule-making machinery, were held within legislative competence as ancillary to a valid sales tax scheme.

Issues: (i) whether the additional sales tax imposed on dealers whose turnover exceeded the prescribed limit was a valid exercise of taxing power and whether the differential treatment offended Articles 14 and 19(1)(g) of the Constitution of India; (ii) whether the proviso limiting the tax on declared goods was consistent with section 15(a) of the Central Sales Tax Act, 1956; (iii) whether the prohibition on collection of additional tax, the penal provision, and the corresponding rules were within legislative competence and constitutionally valid.

Issue (i): whether the additional sales tax imposed on dealers whose turnover exceeded the prescribed limit was a valid exercise of taxing power and whether the differential treatment offended Articles 14 and 19(1)(g) of the Constitution of India.

Analysis: The additional levy was treated as sales tax in substance. A graded levy based on turnover was held to remain within the taxing power because the higher turnover criterion operated as a rational basis for classification. The Court accepted that dealers with larger turnover form a distinct class with greater capacity to bear tax, and that taxation may legitimately be used to further economic equality. The levy was therefore not regarded as arbitrary or as an unreasonable restriction on the right to carry on business.

Conclusion: The levy under section 2(1) was upheld as constitutionally valid and was held not to offend Articles 14 or 19(1)(g) of the Constitution of India.

Issue (ii): whether the proviso limiting the tax on declared goods was consistent with section 15(a) of the Central Sales Tax Act, 1956.

Analysis: The proviso was read as ensuring conformity with the statutory restriction applicable to declared goods. The Court held that the tax under the principal sales tax enactment and the additional tax had to be read together, and that the combined levy did not exceed the permitted ceiling or the single-stage limitation.

Conclusion: The proviso to section 2(1) was upheld and was found consistent with section 15(a) of the Central Sales Tax Act, 1956.

Issue (iii): whether the prohibition on collection of additional tax, the penal provision, and the corresponding rules were within legislative competence and constitutionally valid.

Analysis: The Court held that the power to levy sales tax includes ancillary and incidental power to determine incidence and to regulate whether the burden may be passed on. The prohibition on collection did not alter the essential character of the tax and was within the legislative field. The penal provision was upheld as consequential to the valid prohibition. The challenge based on section 64-A of the Sale of Goods Act, 1930 and price control principles was rejected because those matters govern private rights between seller and buyer and do not limit legislative competence. The advance collection rule was also sustained because the parent enactment incorporated the machinery of the general sales tax law.

Conclusion: Sections 2(2), 2(3) and 3, and the related rule-making provision and rules, were held valid and within legislative competence.

Final Conclusion: The impugned additional sales tax legislation was sustained in full, and the writ petitions failed.

Ratio Decidendi: A sales tax enactment may validly classify dealers by turnover, regulate the incidence of the tax, and prohibit passing on the burden, provided the levy remains a sales tax in substance and the classification is rational and related to the legislative object.
