State development tax on sale turnover upheld as valid under the State's taxing power and constitutional scheme.

A State levy on taxable turnover from the sale or purchase of goods was upheld as within legislative competence under Entry 54 of List II, read with the expanded constitutional meaning in Article 366(29-A). The court accepted that the U.P. Trade Tax Act used an inclusive definition of "tax", and that Section 3-H created a separate levy linked to the taxable event of sale or purchase. Because the impugned State Development Tax fell within that statutory and constitutional field, no competence-based or constitutional prohibition was established, and the challenge failed on merits.

Issues: Whether the State Legislature was competent to levy State Development Tax under the U.P. Trade Tax Act, 1948.

Analysis: Entry 54 of List II authorises taxation on the sale or purchase of goods, and the expression is to be understood with the expanded meaning given by Article 366(29-A) of the Constitution of India. The Act defined "tax" in an inclusive manner, and the charging scheme was not confined to trade tax alone. Section 3-H created a separate levy on taxable turnover, linked to the event of sale or purchase, and the amended definition of tax expressly brought State Development Tax within the statutory framework. The Court found that the levy operated within the legislative field of tax on sale or purchase of goods and that no constitutional or competence-based prohibition was shown.

Conclusion: The levy of State Development Tax was within legislative competence and the challenge failed.

Final Conclusion: The petition was rejected on merits after upholding the validity of the impugned levy under the taxing power of the State.

Ratio Decidendi: A State tax imposed on the taxable turnover arising from sale or purchase of goods, and brought within an inclusive statutory definition of "tax", is valid if it falls within the legislative field under Entry 54 read with Article 366(29-A) of the Constitution of India.
