The Supreme Court on Friday came down heavily on telecom companies for not having cleared their dues related to adjusted gross revenue (AGR) and slammed the Department of Telecommunications (DoT) for demanding Rs 4 lakh crore from state-run firms. The top court said DoT officials are misusing its earlier judgement, and ordered the telecom department to reconsider its ask from the state-run companies. "This is wholly and totally impermissible," the bench said, while referring to the demand raised against the PSUs. Warning of initiating contempt proceedings against the concerned officers, the Supreme Court asked the government how it used its judgement on the AGR matter to devise the formula to raise demand from the public sector companies.
