Turnover tax on declared goods and statutory interest provisions are analysed as valid under the Bengal sales tax scheme.

The commentary examines turnover tax under section 6B of the Bengal Finance (Sales Tax) Act, 1941 and explains that the levy on declared goods such as rice is structured as a single-stage sales tax, with rule 3(2A) preventing repeat taxation where tax has already been paid on a prior West Bengal sale. It states that the distinction between imported rice and locally purchased rice depends on whether the first taxable sale has already suffered tax, not on origin, and that the levy does not impede free trade under articles 301, 303 or 304(a). It further notes that graduated turnover slabs under section 6B(3) are treated as a valid economic classification under articles 14 and 19(1)(g), and that section 10A applies interest from statutory dates, not merely from assessment.

Issues: (i) Whether turnover tax under section 6B of the Bengal Finance (Sales Tax) Act, 1941 read with rule 3(2A) of the Bengal Sales Tax Rules, 1941 is invalid or unconstitutional for allegedly discriminating against imported rice and violating articles 301, 303 and 304(a) of the Constitution of India; (ii) Whether section 6B(3) of the Bengal Finance (Sales Tax) Act, 1941, which prescribes graduated slabs of turnover tax, is arbitrary or violative of articles 14 and 19(1)(g) of the Constitution of India; (iii) Whether section 10A of the Bengal Finance (Sales Tax) Act, 1941, relating to interest on delayed payment, is unconstitutional or liable to be construed as permitting interest only from the date of assessment.

Issue: (i) Whether turnover tax under section 6B of the Bengal Finance (Sales Tax) Act, 1941 read with rule 3(2A) of the Bengal Sales Tax Rules, 1941 is invalid or unconstitutional for allegedly discriminating against imported rice and violating articles 301, 303 and 304(a) of the Constitution of India.

Analysis: Rice is a declared goods under section 14 of the Central Sales Tax Act, 1956 and is subject to the restriction under section 15 of that Act that tax cannot exceed the prescribed ceiling and cannot be levied at more than one stage. The turnover tax under section 6B is a tax on sales, and rule 3(2A) operates to ensure that where tax has already been levied on a prior sale in West Bengal, turnover tax is not again imposed. The distinction between rice imported from outside the State and rice already purchased in West Bengal is not a distinction based on origin but on whether the first taxable sale in West Bengal has already suffered tax. The taxable event is sale, not import, and the levy does not create any direct and immediate impediment to the free flow of trade.

Conclusion: The challenge under articles 301, 303 and 304(a) fails and the levy is upheld.

Issue: (ii) Whether section 6B(3) of the Bengal Finance (Sales Tax) Act, 1941, which prescribes graduated slabs of turnover tax, is arbitrary or violative of articles 14 and 19(1)(g) of the Constitution of India.

Analysis: The graduated rates are based on the quantum of turnover and reflect classification by economic superiority. In taxing legislation, wider latitude is available in making classifications, and mere hardship in individual cases does not by itself establish unconstitutionality. The slab structure bears a nexus to the legislative object and does not impose an arbitrary restriction on the right to carry on business.

Conclusion: Section 6B(3) is not violative of articles 14 or 19(1)(g).

Issue: (iii) Whether section 10A of the Bengal Finance (Sales Tax) Act, 1941, relating to interest on delayed payment, is unconstitutional or liable to be construed as permitting interest only from the date of assessment.

Analysis: Interest under section 10A is attracted from the dates specified in the provision and not from the date of assessment. The provision had already been upheld in earlier decisions and the authorities relied upon support the proposition that interest is a legitimate incident of delayed payment of tax. No basis was shown to read down the provision as suggested, and the constitutional challenge was not made out.

Conclusion: Section 10A is valid and interest is payable in accordance with the statutory dates, not only from assessment.

Final Conclusion: The constitutional challenges to the turnover tax and interest provisions were rejected, and the Tribunal left only a limited liberty to the assessing authority to recalculate turnover tax for completed assessments if the statutory proviso had not been considered.

Ratio Decidendi: Where tax on declared goods is levied only at a single stage without discriminatory rates and the levy is structured to prevent double taxation on prior sales, it does not offend articles 301, 303 or 304(a); a turnover-based slab system in a taxing statute is a valid classification when it reflects economic gradation and bears a rational nexus to the tax scheme.
