A Supreme Court bench comprising Justices G.S. Singhvi and A.K. Ganguly has asked the CBI to investigate prominent corporate houses which were beneficiaries of the 2G spectrum issue, without being influenced by their status, according to news reports.

The court also asked the agency to establish a special court, exclusively to try the spectrum case. The bench commented that there were a large number of persons who thought of themselves to be law and who must be caught. This, it added, should be done with greater expedition.

Advocate Prashant Bhushan, appearing for an NGO, Centre for Public Interest Litigation, pointed out that the agencies have not questioned the heads of several companies including the Swan technology, which was controlled by Anil Ambani?s Reliance Group, when the spectrum was allocated.

At this, the Bench said that it was surprising that the managing directors of the operators companies were not questioned. The court added that the freedom of probe agencies should not be curtailed and they should go beyond the role of the four persons already arrested and reveal the names of conspirators.
