Purchase tax on replacement parts fails where defective parts are retrieved under a maintenance arrangement without a statutory purchase

Section 7-A of the Tamil Nadu General Sales Tax Act, 1959 applies only where the dealer first purchases goods in the statutory sense and the goods are then consumed, disposed of otherwise than by sale, despatched outside the State, or used as contemplated by the Act. On the facts, the defective spare parts were not purchased from customers; they were retrieved as part of an annual maintenance and replacement arrangement when new parts were supplied. Because the statutory precondition of a purchase was absent, purchase tax could not be levied on the defective parts. The Tribunal's view was therefore sustained and the revenue challenge failed.

Issues: Whether purchase tax under Section 7-A of the Tamil Nadu General Sales Tax Act, 1959 could be levied on defective spare parts retrieved from customers while replacing them with new parts in the course of maintenance services.

Analysis: Section 7-A applies only where a dealer purchases goods from a registered dealer or any other person in circumstances where no tax is payable under the Act and the purchased goods are thereafter consumed, disposed of otherwise than by sale, despatched outside the State, or installed and used in the factory. On the facts found, the assessee did not purchase the defective spare parts from the customers. The transaction was one of replacing old defective parts with new parts, and the Tribunal had already found that the retrieval of defective parts formed part of the annual maintenance arrangement. In the absence of any purchase of the defective parts by the assessee, the statutory precondition for levy of purchase tax was not satisfied. The reasoning was also consistent with the later understanding of warranty and replacement transactions as composite commercial arrangements, but the decisive point remained the absence of a purchase within the meaning of Section 7-A.

Conclusion: Purchase tax under Section 7-A could not be levied on the defective spare parts, and the challenge to the Tribunal's order failed.

Final Conclusion: The assessee was not liable to purchase tax on the disputed transactions, and the revenue appeal was rejected.

Ratio Decidendi: Section 7-A of the Tamil Nadu General Sales Tax Act, 1959 is attracted only where there is a purchase of goods by the dealer within the statutory sense; mere replacement of defective parts under a maintenance arrangement, without such purchase, does not give rise to purchase tax liability.
