Idea's challenge to the TRAI recommendation, before a bench of Chief Justice G Rohini and Justice Sangita Dhingra Sehgal on Tuesday, follows an earlier petition filed by Vodafone against a Rs 1,050-crore recommendation on the same grounds, which is currently pending before another bench of the court. Alongside Idea and Vodafone, TRAI had on October 21, 2016 also recommended a Rs 1,050-crore penalty against Bharti Airtel, taking the total tally to Rs 3,050 crore against the three service providers. Subsequently, DoT had on January 12 received confirmation from the Attorney General's office that the imposition of such a penalty was legal and within the scope of the law.
