C.T. Kochouseph v. State of Kerala and Anr. Etc.
Background
This decades-old batch of tax appeals asked whether a business that purchased goods from a seller who was exempt from sales tax could still be made to pay a separate "purchase tax" under Section 5A of the Kerala Act or Section 7A of the Tamil Nadu Act, when it later used those goods to manufacture other goods or sent them outside the state. Though the old sales-tax regime has since been replaced by VAT and GST, these pending disputes still needed to be resolved under the law as it stood. The appellant-assessees argued that if the seller's sale was exempt from tax, no purchase tax could arise on the same transaction.
Decision Breakdown
The Supreme Court held that purchase tax under these provisions is a separate, independent charge that is deliberately triggered precisely because the seller's sale was tax-exempt: an exemption granted to the seller does not automatically flow through to exempt the purchaser from this distinct tax. Relying on its earlier three-judge decision in State of Tamil Nadu v. M.K. Kandaswami and the later ruling in Hotel Balaji, the Court explained that "goods the sale or purchase of which is liable to tax" refers to the category of taxable goods generally, not whether tax was actually paid on that specific sale, and rejected the contrary view taken in Goodyear India. The Court also upheld the constitutional validity of both provisions and dismissed all the assessees' appeals.
Lesson Learnt
A tax exemption granted to a seller does not automatically extend to exempt the buyer from a separate charge like purchase tax: each taxing provision must be read on its own terms, and businesses cannot assume that one party's tax relief automatically shields the other side of the same transaction.
