The Delhi High court on Monday issued a notice and sought response from the Telecom Regulatory Authority of India (TRAI) on a plea challenging its tariff order making it mandatory for cellular operators to compensate subscribers for call drops from January 1, while declining to issue any interim order. The bench of Chief Justice G Rohini and Justice Jayant Nath issued notice to the regulator on a plea moved by cellular operators, who termed the order as mutually contradictory and destructive. "Since it has to be implemented from January 1, 2016, we will hear the government and pass the order," the bench said while listing the matter for December 22. The bench declined to hear detailed arguments from senior advocate Harish Salve, who was appearing on behalf of the telecom companies. The operators have sought quashing of the Trai's October 16 ruling mandating service providers to pay subscribers Re 1 per call drop experienced on their network, subject to a cap of three a day.
