Tax concession classification upheld where fuel efficiency and engine capacity were treated as relevant, non-discriminatory criteria.

A concessional sales tax notification limited to fuel-efficient light commercial vehicles with engine capacity between 3200 cc and 3500 cc was examined under Articles 14 and 19(1)(g). The classification was upheld because taxation measures need only satisfy rational, uniform treatment among similarly situated persons, not perfect equality. Engine capacity was treated as a relevant criterion linked to power, safety, durability, operating economy, and suitability to local terrain, and the notification applied equally to all manufacturers meeting both conditions. It therefore was neither arbitrary nor discriminatory, and it did not infringe trade rights because it denied only a tax concession, not the ability to trade.

Issues: Whether the notification granting concessional sales tax only to fuel efficient light commercial vehicles with engine capacity between 3200 cc and 3500 cc was discriminatory or arbitrary and therefore violative of Article 14 of the Constitution of India; whether the same notification unreasonably restricted the petitioner's trade and offended Article 19(1)(g) of the Constitution of India.

Analysis: In taxation matters, perfect equality is not required and the validity of a taxing classification depends on whether the classification is based on relevant considerations and operates uniformly on persons similarly situated. The condition in the notification was examined as a twofold classification: fuel efficiency and specified engine capacity. The engine capacity criterion was treated as a relevant factor because higher cubic capacity was linked with higher horse power, safety, longer life, better operating economy, and better suitability for the terrain and road conditions prevalent in the State. The notification applied alike to all manufacturers who satisfied both conditions, irrespective of collaboration or location, and therefore did not single out any class for hostile treatment.

Conclusion: The notification was held to be neither arbitrary nor discriminatory and not violative of Article 14. It was also held not to infringe Article 19(1)(g) because it did not prohibit or restrict the petitioner's , only denied a concessional tax benefit to a vehicle that did not satisfy the prescribed conditions.

Final Conclusion: The writ challenge to the concessional sales tax notification failed because the fiscal classification was upheld as a valid and reasonable one.

Ratio Decidendi: In taxation, a concessional classification is constitutionally valid if it is founded on relevant criteria, applies uniformly to all persons within the class, and is not shown to be arbitrary or hostile discrimination.
