The Department of Telecommunications (DoT) is likely to seek legal opinion from the solicitor general on whether telcos need to make an upfront payment of 10% of their adjusted gross revenue (AGR) dues in the current financial year, amid different interpretations of the Supreme Court order by the two sides. Telcos such as Vodadone Idea and Bharti Airtel are of the view that they have already paid more than 10% of their total AGR dues, which include license fees, spectrum usage charges, interest and penalties, and that their first installment falls due only in the fiscal year ending March 2022.But a senior govt official said that DoT's interpretation is that the judgement requires telecom companies to pay 10% of their remaining AGR dues in the current fiscal year (FY21), and the rest over 10 years. "Vodafone Idea has communicated to the government (about its interpretation), and there is a bit of a deadlock here, because of which DoT is considering taking legal opinion," said the official.
