The Supreme Court has held that heavy earth-moving machinery and construction vehicles used only inside factories, mines, or other enclosed industrial premises are not “motor vehicles” under Section 2(28) of the Motor Vehicles Act, 1988. As a result, such vehicles are not liable to pay road tax.
A Bench of Justice Pankaj Mithal and Justice Prasanna B. Varale delivered the ruling. The Court also set aside the Gujarat High Court judgment and allowed the appeal filed by Ultratech Cement Limited.
Core legal issue before the Court
The dispute centred on the meaning of “motor vehicle” under Section 2(28) of the Motor Vehicles Act, 1988. The provision covers mechanically propelled vehicles adapted for use on roads, subject to certain exclusions.
The Supreme Court said the law excludes special vehicles designed only for use within enclosed premises. It stressed that such machines are not meant for public road use.
The Court noted that the machines in question never operated on public roads. Instead, trailers transported them into factory sites. Therefore, the Court held that they could not be treated as motor vehicles for registration or road tax purposes.
Constitutional limit on road tax
The Supreme Court also examined the State’s power to levy tax. It referred to Entry 57 of List II of the Seventh Schedule to the Constitution. That entry allows States to tax vehicles suitable for use on roads.
The Court reiterated that a State cannot tax vehicles that are not suitable for public road use. It said any tax beyond that constitutional limit would be impermissible.
The Bench also noted that the Gujarat Motor Vehicles Tax Act, 1958, does not prescribe a specific tax rate for such construction equipment vehicles. This, the Court said, further showed that the legislature did not intend to impose road tax on them.
Bench restores relief to Ultratech Cement
The Bench allowed Ultratech Cement’s appeal and set aside the tax demands upheld by the High Court. It clarified that these machines are off-road industrial vehicles and remain exempt from road tax so long as they stay within enclosed industrial premises.
However, the Court added an important qualification. If any such machinery is used on a public road, it will lose the exemption. In that event, the vehicle may attract registration requirements, motor vehicle tax, penalties, and other sanctions under the law.
Why the judgment matters
The ruling gives major relief to industries that operate heavy machinery within factory limits, mines, or closed worksites. It removes tax and registration burdens for equipment that is not designed or intended for road use.
The judgment also clarifies the constitutional boundary of State taxation. It confirms that tax liability depends on whether a vehicle is suitable for public roads, not merely on whether it is mechanically propelled.
Conclusion
The Supreme Court has made it clear that industrial vehicles used only in enclosed premises do not attract road tax if they are not adapted for use on roads. The ruling strengthens legal certainty for companies and clarifies the scope of motor vehicle taxation.
