New Delhi, Oct. 2 -- The Supreme Court has directed states and Union territories (UTs) to freeze online and other vehicle-related services, including renewal of registration, issuance of fitness and pollution-under-control certificates, ownership transfers and even renewal of driving licences, where traffic fines remain unpaid, as part of a nationwide push to make electronic enforcement of road-safety laws more effective. A bench of justices JB Pardiwala and KV Viswanathan, in an order released on Thursday, also directed that vehicles with outstanding e-challans be blacklisted on the central Parivahan portal, blocking their sale or transfer, while no centre should be permitted to issue a PUC certificate until pending traffic fines are cleared. In cases involving multiple violations, authorities have been told to suspend renewal of the driving licence and take steps to suspend an existing licence. The bench said that merely issuing thousands or lakhs of e-challans served little purpose unless authorities were able to recover the fines. The court was informed that about Rs.49,194.05 crore was outstanding against e-challans issued over a period of time, of which Rs.26,175.05 crore had been recovered so far. The court emphasised that authorities had to work at the "ground level having regard to the ground realities"....
