Composite works contracts may include a taxable sale element, but tax assessment cannot rely on an arbitrary proxy for goods price.

Composite works contracts can contain a taxable sale element where goods are supplied for price and title passes, even if the materials are affixed to immovable property before completion; the State therefore had competence under Entry 54 to tax that materials component. The sales element was treated as occurring in the course of inter-State trade or commerce, but the validating legislation was held effective to cure the constitutional defect for the relevant period, so the inter-State objection failed. Rule 8 was invalid because its fixed-percentage deduction method used an artificial proxy rather than the actual price of goods sold, and it risked taxing labour or services; it was struck down as ultra vires.

Issues: (i) whether works contracts involving supply and affixation of materials can be treated as "sale of goods" within Entry 54 of the State List; (ii) whether the transactions, if sales, were sales in the course of inter-State trade or commerce and, if so, whether the validating legislation removed the constitutional bar; (iii) whether Rule 8 of the Madhya Bharat Sales Tax Rules, which prescribed an artificial method for determining the sale price in works contracts, was ultra vires.

Issue (i): whether works contracts involving supply and affixation of materials can be treated as "sale of goods" within Entry 54 of the State List

Analysis: The decisive inquiry was whether the constitutional expression "sale of goods" must be confined to the ordinary legal meaning of a completed transfer of property for price, or whether it could be read widely enough to include the materials element in composite works contracts. The Court treated the legislative entry as requiring a liberal construction, but also recognised that a taxable sale must still contain the essential ingredients of sale, namely goods, a bargain for price, payment or promise of price, and passing of title. On the facts, the contracts for electrical installations and fittings involved substantial supply of materials for money consideration, and the fact that the materials were affixed to immovable property before completion did not, by itself, exclude the existence of a sale element.

Conclusion: The works contracts were held to involve sale of goods to the extent of the materials supplied, and the State Legislature had competence under Entry 54 to tax that element.

Issue (ii): whether the transactions, if sales, were sales in the course of inter-State trade or commerce and, if so, whether the validating legislation removed the constitutional bar

Analysis: The materials were dispatched from outside the State for delivery and use in Madhya Bharat, and therefore the sales element was treated as occurring in the course of inter-State trade or commerce. The Court further held that the validating legislation cured the constitutional defect for the relevant period, and that the existence of Section 23A in the State Act did not prevent the validating enactment from operating on the earlier assessments. The challenge based on inter-State character therefore failed.

Conclusion: The inter-State trade objection did not succeed, and the validating legislation was held effective to sustain the levy for the relevant period.

Issue (iii): whether Rule 8 of the Madhya Bharat Sales Tax Rules, which prescribed an artificial method for determining the sale price in works contracts, was ultra vires

Analysis: The rule permitted deduction of only a percentage fixed by the Commissioner from the lump sum consideration for a works contract, rather than determining the actual price of the materials sold. The Court accepted that the Act contained sufficient machinery to tax the materials element in a composite contract, but held that the particular rule adopted an artificial and arbitrary standard that did not reliably ascertain the price of the goods sold and risked taxing services as well as goods. That method was incompatible with the constitutional power to tax sales of goods.

Conclusion: Rule 8 was held ultra vires and void.

Final Conclusion: The petition succeeded only to the extent that Rule 8 was struck down, while the challenge to the levy on works-contract materials and the inter-State objection failed.

Ratio Decidendi: A composite works contract may contain a taxable sale element where goods are transferred for price, but any rule used to assess tax on that element must ascertain the true price of the goods sold and cannot impose an arbitrary or artificial proxy that effectively taxes labour or services.
