Treaties and tax classification: State excise notifications upheld where international obligations lacked domestic implementation and wine levies were non-discriminatory.

International treaties do not, by themselves, create enforceable domestic law or invalidate State excise notifications unless Parliament implements them under Article 253. Communications from the Union expressing policy preference had no binding legal effect, so the treaty-based challenge failed. In taxation, the State had wide latitude to classify imported wines separately from domestically produced wines for fees and duties, and the levy was not shown to be hostile or irrational under Article 14. The impugned notifications were therefore sustained, and the differential fiscal treatment was upheld as a permissible classification.

Issues: (i) Whether international trade treaties and the principle of national treatment could invalidate State excise notifications in the absence of parliamentary legislation under Article 253 of the Constitution of India; (ii) Whether the classification between imported wines and domestically produced wines for levy of fees and duties was arbitrary or discriminatory under Article 14 of the Constitution of India.

Issue (i): Whether international trade treaties and the principle of national treatment could invalidate State excise notifications in the absence of parliamentary legislation under Article 253 of the Constitution of India.

Analysis: The constitutional scheme recognizes the Union executive power to enter into treaties, but treaties do not by their own force become enforceable municipal law against Indian nationals. Where treaty obligations restrict rights or alter domestic law, parliamentary legislation is required for implementation under Article 253. In the absence of such legislation, subordinate legislation made by the State cannot be struck down merely for inconsistency with the treaty regime. Communications from the Union expressing a policy preference did not amount to binding law.

Conclusion: The challenge based on Article 253 and the international treaties failed.

Issue (ii): Whether the classification between imported wines and domestically produced wines for levy of fees and duties was arbitrary or discriminatory under Article 14 of the Constitution of India.

Analysis: Taxation statutes enjoy wide latitude in classification, and a levy will fail only if the selection operates unequally within the chosen class without a rational basis. Imported wines retain their identity as imported goods and may be treated as a separate class for fiscal purposes. The burden of proving hostile discrimination was not discharged, and the differential levies were within the State's fiscal discretion.

Conclusion: The classification was upheld and no Article 14 infirmity was found.

Final Conclusion: The impugned notifications were sustained, as the State measures could not be invalidated on treaty grounds and the differential fiscal treatment of imported wines was held to be a permissible classification.

Ratio Decidendi: International treaties do not operate as enforceable domestic law unless implemented by legislation, and in taxation matters a State may classify imported goods separately if the classification is reasonable and non-discriminatory.
