New Delhi (Agencies): A Supreme Court bench hearing the 2G spectrum scam on Tuesday told GSM lobby group COAI to obtain nod from the Chief Justice of India to transfer their plea challenging the Dual Technology Spectrum allocation policy of the government.

The court bench headed by Justice G S Singhvi and A K Ganguly told the Cellular Operators Association of India (COAI) that it could hear their plea only after the CJI permits them.

"Unless order of CJI is on that, we would not take up the case," the bench said.

COAI's plea is being heard by a separate bench comprising Justices Altamas Kabir and Cyriac Joseph. However, the lobby has asked for its petition to be transferred before the bench of Justices G S Singhvi and A K Ganguly.

The bench of Justices Singhvi and Ganguly has ordered a court-monitored probe by the CBI and Enforcement Directorate into the alleged scam involving former Telecom Minister A Raja, who, according to CAG report, has caused a presumptive loss of Rs 1.76 lakh crore to the exchequer.

During the previous hearing on February 10, the bench had asked the CBI to bring those corporate houses under its scanner that were beneficiaries of the 2G scam without being
influenced by their status.

The COAI had approached the Supreme Court in 2009 challenging the judgement of telecom tribunal TDSAT, which upheld DoT's dual technology spectrum allocation policy.

It had made DoT, Trai, RCom, Tata Tele, HFCL Infotel Ltd and others as parties to its plea.

The Telecom Disputes Settlement and Appellate Tribunal, on March 31, 2009, upheld DoT's dual spectrum allocation policy allowing Anil Ambani group company RCom and Tata Tele -- who operated CDMA based cellular services -- to get GSM spectrum for operating services.

The petition filed by COAI, Bharti Airtel, Idea Cellular, Spice Communications and Vodafone Essar said TDSAT wrongly upheld DoT's decision to enhance the criteria for allocation of additional spectrum, besides upholding the dual spectrum allocation policy.

The plea charged that TDSAT failed to appreciate that cellular operators had a vested and accrued right to receive spectrum up to 15 MHz.

The DoT, on October 18, 2007, amended the telecom rules, allowing CDMA players to enter the GSM mobile space.
