The Supreme Court on Thursday directed the Central Bureau of Investigation (CBI) to "take action in the matter of prosecution" of the telecom companies and public servants mentioned in its report, prepared by A P Singh, the outgoing director. The three companies involved in the proceedings before the court were Bharti Cellular, New Delhi (now known as Bharti Airtel), Hutchison Pvt Ltd, Mumbai and Sterling Cellular, New Delhi (the last two part of Vodafone India now). The public servants whose names were discussed in the proceedings include former telecom secretary Shyamal Ghosh and deputy director-general J R Gupta. Since the CBI report in the 2G spectrum scam, submitted to the bench of judges G S Singhvi and K S Radhakrishnan, was in a sealed cover and they ordered immediate sealing after the hearing, the full list of accused persons is not immediately available. The order on Thursday was passed in the petition moved by the Centre for Public Interest Litigation, represented by counsel Prashant Bhushan.
