In the wake of the recent sting operation by an undisclosed person who apparently recorded a face-to-face conversation between CBI prosecutor AK Singh and Unitech MD Sanjay Chandra accused in the 2G spectrum scam, the Centre for Public Interest and Litigation (CPIL) has moved the Supreme Court to direct a committee or the Central Vigilance Commission (CVC) to examine the trial court record of the case.

It was on NGO CPIL’s petition that the SC had directed a court-monitored CBI probe and also cancelled the 122 licences of "ineligible companies" that were allocated 2G spectrum during A Raja's tenure.

The CPIL's application also wants examination of the statements made by prosecution witnesses before the trial to ascertain any nexus between the prosecution and key corporate accused.

“This is important as there is a danger of the collapse of the entire trial against the accused," stated the application.

Seeking a direction to the CBI to send the tapes of the conversation to a truth lab, the NGO alleged the agency had not filed an FIR  into the revelations made in the sting operation.

The NGO said the tapes were in the government labs and it was easy for “political leadership” to obtain convenient reports.
