The CBI today opposed the bail plea of Unitech Wireless'' MD Sanjay Chandra and Swan Telecom's Director Vinod Goenka in the Supreme Court for their alleged involvement in 2G scam saying that they should not be granted relief in larger interest of society.

Additional Solicitor General Haren Raval submitted before a bench headed by Justice G S Singhvi that they should not be released on bail and the case is at the stage of framing of charges.

"In corruption cases, right to liberty of the accused has to be seen in the light of larger public interest," the ASG said explaining the magnitude of the scam.

He also submitted that India has recently ratified United Nation Convention on Corruption which says that there should be strong legal mechanism to fight corruption.

The investigating agency, in its reply filed in court, has also contended that they are likely to tamper with evidence and influence witnesses in the 2G scam if they are allowed to come out on bail.

"There is every likelihood that the petitioners may tamper with evidence and influence vital witnesses which will eventually hamper the proper and effective trial in this case to reach a logical conclusion," the CBI said in its affidavit.

The court was hearing bail pleas of Chandra and Goenka, who have refuted all the allegations levelled against them by the CBI.
