Motor vehicle tax applies only to public-road use, while valid non-user certificates bar recovery absent actual use.

Motor vehicle tax under the Bombay Motor Vehicles Tax Act, 1958 is attracted only where a vehicle is used or kept for use on public roads, reflecting the compensatory nexus required by Entry 57 of List II. The statutory presumption of use is displaced when the owner gives advance intimation and the Taxation Authority issues a valid non-user certificate. Rule 5 also recognises exemption for vehicles intended for exclusive use in a non-public place, and tax can be recovered only if actual use during the certified period is shown. Vehicles operating solely within an enclosed factory on privately maintained roads fall outside the taxing scheme unless breach of the certificate is established.

Issues: Whether motor vehicles used exclusively within the petitioner's private factory premises were liable to tax under the Bombay Motor Vehicles Tax Act, 1958, and whether the impugned demand notices could be sustained despite earlier non-user certificates issued under the Bombay Motor Vehicles Tax Rules, 1959.

Analysis: Section 3(2) of the Bombay Motor Vehicles Tax Act, 1958 creates a presumption that a registered motor vehicle is used or kept for use in the State, but that presumption is displaced where the owner gives advance intimation and the Taxation Authority certifies non-user. Rule 5(1) of the Bombay Motor Vehicles Tax Rules, 1959 enables exemption where the vehicle is intended to be used exclusively in a place which is not a public place, and Rule 5(2) preserves the authority's power to recover tax only if the vehicle is later found to have been actually used or kept for use in the State during the certified period.

Analysis: The expression "public place" in the Full Bench decision relied on by the revenue was held to be context-specific and confined to the scheme of the Motor Vehicles Act, 1939. For the taxing statute, the relevant scheme and Entry 57 of List II require a compensatory nexus with use of public roads. Vehicles operated only within enclosed factory on privately maintained roads, and never on State or local authority roads, do not answer that description. The respondents had not shown any breach of the non-user certificates or any actual use of the vehicles on public roads during the certified periods.

Conclusion: The vehicles were not liable to tax for the certified non-user periods, and the demand notices founded on the contrary view were unsustainable.

Final Conclusion: The writ petition succeeded, the impugned tax demands and rejection orders were set aside, and refund with interest was directed.

Ratio Decidendi: Motor vehicle tax under Entry 57 and the State taxing enactment is exigible only where the vehicle is used or kept for use on public roads, and a valid non-user certificate protects the owner unless actual use during the certified period is established.
