Case Note & Summary
The appeals arose from a common judgment of the Madras High Court allowing writ petitions filed by dealers (respondents) who challenged the constitutional validity of Section 8(2)(b) of the Central Sales Tax Act, 1956. The provision prescribed that tax on inter-State sales of goods other than declared goods to persons other than registered dealers or government (where C or D forms were not furnished) was to be calculated at the higher of 10% or the rate applicable to intra-State sales in the appropriate State. The respondents contended that this led to varying tax rates across States, imposing dissimilar burdens on the same or similar commodities and thereby violating Articles 301 and 303(1) of the Constitution. The High Court accepted their claims, holding the provision bad; the State of Tamil Nadu appealed. The Supreme Court traced the constitutional history of sales tax and inter-State trade restrictions. It noted that Article 286 was enacted to prevent multiple taxation of inter-State sales by States, and after the Constitution (Sixth Amendment) Act, 1956, Parliament was vested with exclusive authority to tax inter-State sales. The Central Sales Tax Act, 1956 was enacted under Article 269(3) and Article 286. Section 8 classified inter-State sales into three categories: sales to government or registered dealers taxable at 3% under Section 8(1); sales of declared goods taxable at the State rate under Section 8(2)(a); and other sales taxable at the higher of 10% or the State rate under Section 8(2)(b). The main issues were whether Section 8(2)(b) violated Article 301 (freedom of trade and commerce) and Article 303(1) (prohibition on preference or discrimination between States). The respondents argued that the differing State rates caused unequal tax burdens and impeded free flow of trade. The State contended that Parliament had power under Article 302 to impose restrictions in public interest, and that the provision was enacted to check evasion of sales tax. The Court held that Article 301 is subject to Article 302, which empowers Parliament to impose restrictions on inter-State trade as required in the public interest. Prevention of tax evasion is a measure in public interest; therefore, Parliament was competent to enact Section 8(2)(b) even if it imposed restrictions on inter-State trade. There was no basis to presume that the higher rate was not in public interest. Accordingly, Article 301 was not violated. On the discrimination issue, the Court relied on State of Madras v. N. K. Nataraja Mudaliar, which held that different rates of tax on the same commodity in different States do not by themselves constitute discrimination under Article 303(1), because the flow of trade depends on factors such as source of supply, place of consumption, trade channels, freight rates, and transport facilities, not merely tax rates. Thus, Section 8(2)(b) did not offend Article 303(1). Consequently, the Supreme Court allowed the appeals, set aside the High Court's judgment, and upheld the constitutional validity of Section 8(2)(b) of the Central Sales Tax Act, 1956. The provision remains enforceable, and the respondents were liable to tax at the higher prescribed rate on the disputed inter-State sales transactions.
Headnote
A) Constitutional Law - Freedom of Trade and Commerce - Article 301, 302 - Parliament's Power to Restrict Inter-State Trade in Public Interest - Constitution of India, Articles 301, 302 - Section 8(2)(b) of Central Sales Tax Act, 1956 imposed a higher tax rate on inter-State sales to unregistered dealers or government without prescribed forms. Respondents challenged the provision as an unreasonable restriction on free trade under Article 301. The Court held that prevention of tax evasion is a public interest measure, and Parliament is competent under Article 302 to impose such restrictions even if they affect inter-State trade. No presumption existed that the 10% rate or State rate (whichever higher) was not in public interest; thus the provision was valid. Held that Section 8(2)(b) does not violate Article 301. (Paras 1-7) B) Constitutional Law - Discrimination Between States - Article 303(1) - Different Tax Rates Not Per Se Discriminatory - Constitution of India, Article 303(1) - Section 8(2)(b) was challenged as giving preference or making discrimination between States because varying State sales tax rates led to different tax burdens on similar goods. Following State of Madras v. N. K. Nataraja Mudaliar, the Court held that differing rates of tax on the same commodity in different States do not by themselves amount to discrimination; the flow of trade depends on factors such as source of supply, consumption, trade channels, freight, and transport facilities. Therefore, no violation of Article 303(1). Held that Section 8(2)(b) is not discriminatory. (Paras 6-8)
Issue of Consideration
Whether Section 8(2)(b) of the Central Sales Tax Act, 1956 violates Articles 301 and 303(1) of the Constitution by imposing a higher rate of tax on certain inter-State sales.
Final Decision
Appeals allowed; the Supreme Court set aside the High Court's judgment and upheld the constitutional validity of Section 8(2)(b) of the Central Sales Tax Act, 1956. The Court held that Parliament was competent to enact the provision under Article 302 as a measure in public interest to prevent evasion of tax, and that different rates of tax in different States did not per se amount to discrimination under Article 303(1).
Law Points
- Prevention of tax evasion is a measure in public interest under Article 302
- Parliament can impose restrictions on inter-State trade in public interest
- Different rates of tax in different States on same commodity do not per se violate Article 303(1)
- Flow of trade depends on multiple factors not just tax rates
