Compensatory motor vehicle tax upheld where receipts matched road expenditure and standby buses were treated as taxable vehicles.

The Supreme Court examined whether an enhanced motor vehicle tax under the Andhra Pradesh Motor Vehicles Taxation Act, 1963 was compensatory and therefore consistent with freedom of trade and commerce. On the material considered, the tax receipts did not exceed spending on roads and allied transport facilities, so the levy was treated as compensatory rather than a device for general revenue. The Court also considered whether the increased rate imposed an unreasonable restraint on the right to carry on business and found no destructive burden or lack of public interest. It further addressed whether spare buses kept as standby vehicles could be taxed and treated such vehicles as falling within the levy because they were maintained for use in the transport operation.

Issues: (i) whether the enhanced motor vehicle tax under the Andhra Pradesh Motor Vehicles Taxation Act, 1963 and the impugned notifications constituted a compensatory levy and so did not offend the freedom of trade and commerce under the Constitution; (ii) whether the increased rate of tax was an unreasonable restriction on the right to carry on business and was not justified in public interest; and (iii) whether tax could validly be levied on spare buses kept as standby vehicles.

Issue (i): whether the enhanced motor vehicle tax under the Andhra Pradesh Motor Vehicles Taxation Act, 1963 and the impugned notifications constituted a compensatory levy and so did not offend the freedom of trade and commerce under the Constitution.

Analysis: The taxing scheme was examined in the light of the object of the levy, the budgetary figures placed before the Court, and the relationship between the receipts from the tax and the expenditure on roads and allied purposes. The material showed that the tax receipts did not exceed the expenditure on road construction, maintenance and development. The increase in the levy was therefore found to be directed to meeting the cost of facilities provided for transport operators and not to augmenting general revenue. The levy was accordingly treated as compensatory in character and not as one that impermissibly restricted inter-State or intra-State trade.

Conclusion: The enhanced levy was held to be compensatory and valid, and it did not violate the constitutional guarantee relating to freedom of trade and commerce.

Issue (ii): whether the increased rate of tax was an unreasonable restriction on the right to carry on business and was not justified in public interest.

Analysis: The Court considered whether the burden of the enhanced tax was so heavy as to destroy or seriously cripple the transport business. On the materials before it, the increase was not shown to have made the business unprofitable, especially in the setting of simultaneous fare increases and the continuing viability of the operators. The record did not establish that the measure was merely a revenue-generating device or that it lacked public interest. The restriction was therefore regarded as one falling within the permissible area of regulatory taxation.

Conclusion: The increase in tax was held to be a reasonable restriction supported by public interest and was not unconstitutional on that ground.

Issue (iii): whether tax could validly be levied on spare buses kept as standby vehicles.

Analysis: The statutory language authorised levy on every motor vehicle used or kept for use in a public place. Spare buses, though not run continuously, were necessary for the effective functioning of a transport fleet and could be put on the road whenever required. Since they were maintained for use and formed part of the operating system, their taxation was considered consistent with the compensatory scheme of the Act.

Conclusion: The levy on spare buses was upheld as lawful.

Final Conclusion: The challenge to the enhanced taxation failed on all substantial grounds, and the impugned levy was sustained as a compensatory and reasonable measure applicable to both regular and standby buses.

Ratio Decidendi: A motor vehicle tax that is shown, on the material before the Court, to be compensatory rather than a device for general revenue, and that does not impose a destructive burden on the business, is constitutionally valid; vehicles kept as standby for the transport operation may also be brought within such a levy.
