The bench, meanwhile, today also asked CBI to file a

report on the probe conducted, so far, in the 2G case. Rawal said there was a need for segregating the contents of the tapped conversations which are "actually innocuous, not so innocuous and those with elements of criminality". The court had earlier said that it had gone through some of the tapped conversations and some of them were "innocuous" and hence, the voluminous transcripts were needed to be "scrutinised" to find out elements of "criminality" in them. It had also made clear that the scrutiny would be limited to those conversations which pertain to criminal element and relating to interest of justice. Senior advocate Harish Salve had submitted that the "utmost secrecy" be maintained in the scrutiny of transcripts. He was referring to various conversations that took place between Tata and Radia which are allegedly personal in nature. "There are some conversations in public domain and those are hardly personal in nature. They relate to illegality and shed significant light on how government decisions are being influenced and how institutions run in the country," Bhushan had said. Excerpts from the tapes earlier leaked in the media had sparked a political storm with the conversations bringing out the nature of corporate lobbying and also its purported impact on politics. The income tax department placed transcripts of 5,800 tapped telephone conversations in 50 sealed envelopes. The conversations were recorded as part of surveillance of Radia's phone on a complaint to Finance Minister on November 16, 2007 alleging that within a span of nine years she had built up a business empire worth Rs 300 crore. The government had recorded 180 days of Radia's conversations--first from August 20, 2008 onwards for 60 days and then from October 19 for another 60 days. Later, on May 11, 2009, her phone was again put on surveillance for another 60 days following a fresh order given on May 8.
