Case Note & Summary
The dispute arose from the imposition of a 'lifetime tax' on motor vehicles in Tamil Nadu, challenged by M. Krishnappan, who argued that the tax was unconstitutional and arbitrary. The tax was based on a new index of 'weight-cum-value' introduced by an amendment to the Tamil Nadu Motor Vehicles Taxation Act, 1974, which differentiated between vehicles registered before and after July 1, 1998. The respondent contended that the tax should be based solely on the unladen weight of vehicles, as it was previously, and that the new basis was unrelated to road maintenance. The State defended the tax, citing its success with two-wheelers and asserting that the classification was rational and did not violate Article 14 of the Constitution. The High Court ruled against the State, finding the new tax structure inconsistent with the original Act and non-compensatory. However, the Supreme Court overturned this decision, stating that the 'weight-cum-value' index maintained a necessary nexus with the essential character of the levy, thus upholding the tax's regulatory and compensatory nature. The Court emphasized that the State has the authority to levy taxes on vehicles under Entry 57 of List II of the Seventh Schedule of the Constitution, and that the classification between old and new vehicles was rational and reasonable. The Supreme Court ultimately set aside the High Court's judgment, affirming the validity of the lifetime tax without costs.
