Bail pleas of several corporate czars, arrested in the 2G scam will come up for hearing in the Supreme Court today. The apex court had earlier said the accused can seek bail after framing of charges, which was done on October 22. CBI sources say the agency will oppose the bail pleas of Unitech Wireless MD Sanjay Chandra, Swan Telecom Director Vinod Goenka and ADAG group executives Hari Nair, Gautam Doshi and Surrendra Pipara.
