In a relief to Bharti Airtel and Vodafone Idea, Supreme Court has dismissed billionaire Mukesh Ambani-led Reliance Jio and CCI's plea to probe cartelisation charges against incumbent telecom service providers, CNBC TV18 reported. Notably, the Competition Commission of India (CCI) and Reliance Jio Infocomm had moved the Supreme Court against a Bombay High Court order. The Bombay HC order had quashed the investigation ordered by fair trade regulator CCI into charges of cartelisation against Bharti Airtel and Vodafone Idea in 2017. The CCI had challenged Bombay High Court's order with respect to its jurisdiction before the Supreme Court.

The HC hearing had come on a petition filed by Idea, Bharti Airtel, Vodafone India and the COAI seeking quashing of the CCI order passed on April 21 last year, directing an investigation by its director general into allegations of cartelisation made by Reliance Jio. The Financial Express had reported last year that Reliance Jio had lodged a complaint with the CCI alleging that the three cellular operators had colluded with each other to prevent it from building its customer base.
