D.R. VENKATACHALAM & ORS. vs DY. TRANSPORT COMMISSIONER & OTHERS

The Supreme Court upheld the validity of Rule 155-A of the Motor Vehicles Rules, stating it serves public interest and does not contradict the proviso to Section 47(1) of the Motor Vehicles Act, 1939. The Court found that the assignment of marks under Rule 155-A is equitable and necessary for addressing shortcomings in private transport services compared to government services. The Court dismissed the appeals, affirming that there is no implied prohibition against preferential considerations beyond those explicitly stated in the proviso.
