Broadening the net, the Supreme Court today asked the CBI to bring under its scanner corporate houses which were beneficiaries of the 2G spectrum scam. Giving a free hand to the investigating agency and setting the contours of the probe, the Court asked the government to set up a special court exclusively to try the spectrum scam case. A bench comprising Justices G S Singhvi and A K Ganguly asked the agency to lay its hand on the big corporate houses and the government officials who may have a role in the scam, without being influenced by their status. The Bench reviewed the status reports filed by the probe agencies in which names of big corporates houses and their officers were mentioned. The court asked, why CBI has not taken any action in this regard. It said, freedom of probe agencies should not be curtailed and they should go beyond the role of the four persons already arrested including the former Telecom Minister A Raja and tell the names of conspirators. It questioned CBI's strategy of seeking short custodial remands of the accused and said it must have free hand to question anyone. The bench also barred any other courts from passing any order in the 2G spectrum case which could impede investigations.
