Industrial salt classification and validating levy upheld; octroi treated as a compensatory local tax, not a trade restriction.

Industrial salt was treated as distinct from edible common salt, and the classification was upheld because taxation allows a wide field for intelligible differentia with a rational nexus to the levy's object. The retrospective validating law was also sustained since it applied uniformly to a legally identifiable class of industrial importers and was not invalid merely because one undertaking was the only practical target. Octroi was characterised as a regulatory and compensatory levy on entry of goods for local use, so it did not infringe the freedom of trade or the right to carry on business; the refund claim was further weakened by unjust enrichment.

Issues: (i) whether octroi could validly be levied on industrial salt as distinct from edible common salt under the equality clause; (ii) whether the retrospective validation of the levy under the validation law was unconstitutional as arbitrary or discriminatory; and (iii) whether the levy violated the freedom of trade and the protection of the right to carry on business.

Issue (i): whether octroi could validly be levied on industrial salt as distinct from edible common salt under the equality clause

Analysis: The exemption notification of 30-5-1963 was construed in light of its object and background, which was to exempt salt meant for human consumption and not salt used in industrial manufacture. The record showed that the imported commodity was variously described as salt for chemical industry, industrial salt, and uncrushed salt, and the material also indicated a practical distinction between iodised edible salt and unrefined industrial salt. In taxation matters, the State has wide latitude to classify, and a levy is sustained if the classification is based on an intelligible differentia having a rational nexus with the object of the statute.

Conclusion: The classification between edible common salt and industrial salt was held valid, and the levy did not violate Article 14 of the Constitution of India.

Issue (ii): whether the retrospective validation of the levy under the validation law was unconstitutional as arbitrary or discriminatory

Analysis: The validation measure was held to operate generally across the relevant class of industrial importers and not merely against one unit. A validating law is permissible where the legislature is competent and the measure is not otherwise unconstitutional. The fact that one undertaking may in practice be the only affected concern does not invalidate a class-based fiscal measure if the class is legally intelligible and the statutory treatment is uniform within that class.

Conclusion: The retrospective validation was upheld and was not struck down as arbitrary or discriminatory.

Issue (iii): whether the levy violated the freedom of trade and the protection of the right to carry on business

Analysis: Octroi was treated as a regulatory and compensatory levy on entry of goods for use within municipal limits, not as a tax on movement in transit. Such a levy falls within the legislative field relating to local taxation and, when reasonably imposed, does not infringe the constitutional guarantee of freedom of trade or the right to carry on business. The claim for refund was also weakened by the doctrine of unjust enrichment, as the burden was treated as having been passed on.

Conclusion: No violation of Articles 19(1)(g), 301 or 304 of the Constitution of India was found.

Final Conclusion: The challenge to the octroi levy and the validating legislation failed in all material respects, and the petition was not granted relief.

Ratio Decidendi: In fiscal classification, a levy will be sustained if the differentiated treatment rests on an intelligible differentia with a rational nexus to the taxing object, and a retrospective validating law is valid where it applies uniformly to a legally identifiable class and is otherwise within legislative competence.
