We will dismiss it,” the bench remarked, addressing senior advocate Mukul Rohatgi, who represented Vodafone.Read more: Setback for telecom majors: SC rejects pleas by Vodafone, Airtel, Tata Teleservices for AGR dues waiver, calls appeals ‘misconceived’The apex court had already rejected similar appeals in July 2021, upholding the government’s position on the recovery of dues. On Monday, it again declined to interfere with the Department of Telecommunications’ stance, signaling a firm end to the prolonged litigation on the matter.This comes just days after Vi wrote to the Department of Telecommunications (DoT) that it will not be able to continue operations beyond FY26 without government support on adjusted gross revenue (AGR) dues. In a letter dated April 17, 2025, Vi CEO Akshaya Moondra had written to the Telecom Secretary, saying, “Without GoI’s (Government of India) timely support on AGR, VIL will not be able to operate beyond FY26 as the bank funding discussions will not move forward,” adding that “no support will lead to a point of no return.“Read more: ‘Will not be able to operate beyond FY26,’ says Vodafone Idea’s in a warning while asking for government support on AGR dues
