Check-post document requirements upheld as valid tax regulation, with no breach of trade freedom or equality guarantees.

Sections 29 to 31 of the Kerala General Sales Tax Act, 1963 were upheld as regulatory check-post provisions requiring carriers to carry and produce transport-related documents. The Court held that these requirements are intended to prevent tax evasion and secure effective administration of the sales tax law, so they do not impermissibly restrain the freedom of trade, commerce and intercourse under Article 301. The distinction drawn between railways and motor transport was treated as based on real operational differences and therefore a reasonable classification under Article 14. The constitutional challenge failed, and the impugned provisions were held valid.

Issues: Whether sections 29, 30 and 31 of the Kerala General Sales Tax Act, 1963, which establish check-post requirements and require production of transport-related documents, violate Article 301 of the Constitution of India or Article 14 of the Constitution of India.

Analysis: The requirement that carriers carry and produce documents relating to transport, purchase, ownership or delivery of goods is a regulatory measure intended to prevent evasion of legitimate sales tax and to secure efficient administration of the taxing statute. Such provisions do not amount to an impermissible restraint on the freedom of trade, commerce and intercourse, because that freedom operates within the framework of law. The distinction drawn between railways and motor transport was held to be based on real differences in their character and working, and therefore constituted a reasonable classification for the purpose of the enactment.

Conclusion: The challenge to the impugned provisions failed. The provisions were held not to offend Article 301 or Article 14, and the writ petition was dismissed.

Ratio Decidendi: Regulatory provisions enacted to prevent tax evasion and to facilitate effective tax administration do not infringe the freedom of trade under Article 301 if they operate within the bounds of law, and a classification founded on real operational differences is permissible under Article 14.
