REGIONAL TRANSPORT OFFICER vs K. JAYACHANDRA ETC.

The Supreme Court addressed the permissible alterations to motor vehicles under Section 52 of the Motor Vehicles Act, 1988, and related rules. The Court held that alterations must comply with the manufacturer's specifications as per the prototype test certificate, and Circular No.7/2006 issued by the Transport Commissioner, Kerala, which denied registration for non-compliance, was valid. The Court upheld the High Court's conclusion that structural alterations are permissible under the Kerala Motor Vehicle Rules, thereby resolving conflicting judgments from lower courts.
