Former Tata Group chairman Ratan Tata on Wednesday attended a hearing in the Supreme Court in connection with former corporate lobbyist Niira Radia's phone conversations over the 2G spectrum allocation scandal.
The apex court on Wednesday heard a Public Interest Litigation (PIL) filed by non-governmental organization (NGO) Centre for Public Interest Litigation (CPIL) that sought the tapes be made public.
Tata had filed a petition in the Supreme Court requesting a stay on publication of conversation between him and Radia citing the ´privacy´ clause.
On Aug 4, the apex court said that the tapes were not private conversations and had an "element of criminality".
The controversial tapes contained conversation between corporate lobbyist Niira Radia and several industry leaders in connection to the 2G scam.
On May 28, a Delhi court had warned Radia for evading questions while testifying in an ongoing case over the 2G scandal.
Appearing in court for the first time on that day, Radia had spoken against 2G scam-accused Swan Telecom.
She said that Swan Telecom Pvt Ltd "was not eligible" to get the 2G spectrum licences as it was said to belong to Reliance ADAG group company Reliance Communications.
In its chargesheet into the 2G spectrum scandal filed in April 2011, that had accused former telecoms minister A Raja among others for irregularities, the CBI had named Radia as a prosecution witness.
Radia had been thrust into the centre of the 2G scam probe after taped conversations between her and political and industry powerbrokers including Raja were leaked in the national media.
In perhaps the biggest scam in Independent India, allegedly masterminded by Raja, telecoms spectrum was given away at throwaway prices in 2008 causing a potential revenue loss of up to Rs 1.76 lakh crore.
