New Delhi: The Supreme Court on Wednesday will hear the petitions filed by Janata Party president Subramanian Swamy and lawyer-activist Prashant Bhushan against Union Home Minister P Chidambaram for his alleged role in the 2G spectrum allocation scam.

Swami in his petition has alleged that Chidambaram was equally culpable like former telecom minister A Raja as he also had a role in deciding the spectrum pricing and allowing telecom companies to off-load shares to foreign firms.

Earlier, a special CBI court rejected Swamy's request after which he appealed to the SC against the verdict. The trail court had said that Chidambaram, the finance minister at the time of controversial allocation of 2G spectrum in 2008, was only party to two decisions-keeping spectrum prices at 2001 level and dilution of equity by two companies--which was "not per se criminal".

The other petition by Prashant Bhushan under Centre for Public Interest Litigation, alleges that Chidambaram as Finance Minister overruled his officers who favoured the auction of spectrum.
