Purchase tax under section 5A upheld; levy treated as tax on purchase, not use, and retrospective operation sustained.

Section 5A of the Kerala General Sales Tax Act, 1963 was upheld as a valid purchase-tax provision, because the levy attached to the purchase transaction where statutory conditions were met and was not vague or beyond legislative competence. The court held that the tax was on purchase, not on later use or consumption, and therefore article 301 was not breached as no discriminatory distinction was shown between local and outside goods. It also rejected the challenge to retrospective operation, finding no material that the retrospective levy imposed such a burden on trade as to infringe article 19(1)(g).

Issues: (i) whether section 5A of the Kerala General Sales Tax Act, 1963 was vague, beyond legislative competence, or otherwise invalid as a charging provision; (ii) whether the levy under section 5A was a tax on purchase or a tax on use or consumption, and whether it offended article 301 of the Constitution of India; (iii) whether the retrospective operation of section 5A infringed article 19(1)(g) of the Constitution of India.

Issue (i): whether section 5A of the Kerala General Sales Tax Act, 1963 was vague, beyond legislative competence, or otherwise invalid as a charging provision.

Analysis: The levy was upheld by applying the principle that purchase tax may be imposed where the goods purchased are generally taxable under the Act and the dealer's purchase falls within the statutory conditions. The provision was read as a valid charge on purchase and not as an uncertain or ineffective enactment. The reasoning followed the controlling Supreme Court authority on analogous purchase-tax provisions and rejected the view that section 5A was dependent upon section 5 in the manner contended.

Conclusion: The challenge to the validity and competency of section 5A failed and was decided against the appellants.

Issue (ii): whether the levy under section 5A was a tax on purchase or a tax on use or consumption, and whether it offended article 301 of the Constitution of India.

Analysis: The taxable event was held to be the purchase of goods, not their later use or consumption. The court distinguished authorities dealing with excise and use-tax concepts and held that the section fastened liability on the purchase transaction itself. It further held that article 301 was not attracted because the provision made no discriminatory distinction between goods of the State and goods from outside the State.

Conclusion: The levy was held to be a purchase tax and not a use tax, and no violation of article 301 was established.

Issue (iii): whether the retrospective operation of section 5A infringed article 19(1)(g) of the Constitution of India.

Analysis: A retrospective sales tax or purchase tax does not become invalid merely because the dealer had not provided for its pass-through or because it may affect profitability. The court found no material showing that the retrospective levy had so burdened trade as to amount to a constitutional infringement of the freedom to carry on business.

Conclusion: The retrospective levy was not held to violate article 19(1)(g) and the contention failed.

Final Conclusion: The statutory purchase-tax provision was sustained, the constitutional attacks were rejected, and the writ appeals were dismissed.

Ratio Decidendi: Where a sales tax statute expressly taxes the purchase of goods under specified conditions, the levy is on the purchase transaction itself and is not invalid merely because the goods are later consumed, used, or processed, nor does it offend the freedom of trade absent discrimination or proven constitutional infringement.
