Warranty replacement parts form part of original sale price, so no separate sales tax on replacement transaction.

Warranty replacement of defective car parts was treated as collateral to the original sale under the Sale of Goods Act, so the substituted parts did not constitute a separate sale for sales tax purposes. The consideration for the replacement was regarded as already embedded in the original consolidated price paid for the vehicle, meaning no distinct transfer for fresh consideration arose on each replacement. On that basis, the cost of parts purchased for warranty replacement was also not includible in taxable turnover under the relevant turnover provision. The stated reference was therefore resolved in favour of treating warranty replacements as part of the original sale transaction.

Issues: (i) Whether replacement of defective parts during the warranty period constituted a sale within section 2(g) of the Bengal Finance (Sales Tax) Act, 1941. (ii) Whether, if such replacement was not a separate sale, the cost of parts purchased against registration certificate or C form and used for such replacement was liable to be added to taxable turnover under the second proviso to section 5(2)(ii) of the Bengal Finance (Sales Tax) Act, 1941.

Issue (i): Whether replacement of defective parts during the warranty period constituted a sale within section 2(g) of the Bengal Finance (Sales Tax) Act, 1941.

Analysis: The contract of sale was for cars sold with a warranty undertaking free replacement of defective parts. Applying the distinction under section 12 of the Sale of Goods Act, 1930, the warranty was collateral to the main contract and did not confer a right to reject the car, but only a right to free replacement. When parts were replaced, the property in those parts passed to the buyer, and the consideration for such replacement was not separately stated because it formed part of the price fixed and paid for the car at the time of original sale. The replacement was therefore treated as part of the original consolidated sale and not as an independent transfer for separate consideration.

Conclusion: The replacement of parts under the warranty did not give rise to a separate taxable sale; the first question was answered in the negative.

Issue (ii): Whether the value of parts purchased for such warranty replacement was liable to be included in taxable turnover under the second proviso to section 5(2)(ii) of the Bengal Finance (Sales Tax) Act, 1941.

Analysis: Since the consideration for the replacement parts was already embedded in the original sale price of the vehicle, the parts were not acquired for a separate taxable disposal outside the original transaction. The use of parts in warranty replacement did not create an additional taxable turnover chargeable again on the purchasing dealer under the second proviso.

Conclusion: The purchase price of the parts so used was not liable to be added to taxable turnover; the second question was answered in the negative.

Final Conclusion: The reference was decided in favour of the dealer, and the court upheld the view that warranty replacements formed part of the original sale price and did not attract further sales tax.

Ratio Decidendi: Where goods are sold with a warranty providing free replacement of defective parts, the price of such replacement parts is treated as included in the original sale consideration, so the replacement is not a separate sale for sales tax purposes.
