Regional Transport Officer & Ors. etc. v. K. Jayachandra & Anr. etc.
Background
Several vehicle owners in Kerala were denied registration or renewal after altering their vehicles' bodies or chassis in ways that departed from the manufacturer's original prototype-approved specifications (e.g., extending a bus body beyond the certified chassis length, or cutting a chassis to convert a vehicle into a recovery vehicle), relying on a Transport Commissioner circular requiring strict adherence to the prototype test certificate. Conflicting rulings by different Single Judges of the Kerala High Court on whether such alterations were permissible under the Kerala Motor Vehicle Rules led to a reference to a Division Bench, which held that structural alteration was permissible under the state rules, prompting the transport authorities to appeal to the Supreme Court (with the Ministry of Road Transport impleaded and an amicus curiae appointed given the issue's importance).
Decision Breakdown
The Supreme Court held that Section 52 of the Motor Vehicles Act, 1988 (as amended in 2000) prohibits altering a vehicle such that it departs from the specifications "originally specified by the manufacturer," and that state rules like the Kerala Rules (dealing with inspection, dimensions, and body construction) are subordinate to and cannot override this statutory prohibition. Since the explanation to Section 52 defines "alteration" as a change affecting the vehicle's basic structural features, and the alterations in these cases (extended bus lengths, cut chassis, increased unladen weight) changed basic features at variance with the manufacturer's prototype specifications, the Kerala High Court's view permitting such alterations under its own rules was legally incorrect. The Court set aside the High Court's judgment and allowed the transport authorities' appeals, restoring the denial of registration for non-compliant alterations.
Lesson Learnt
Vehicle owners cannot rely on state-level motor vehicle rules to justify structural alterations (extending bodies, cutting chassis, etc.) that depart from the manufacturer's original prototype specifications: the central statutory bar in Section 52 of the Motor Vehicles Act takes precedence, and such alterations can lawfully be refused registration regardless of local practice.
