M Nageswar Rao, who took over the duties and functions of CBI director late on Tuesday night, appointed Satish Dagar as superintendent of police to probe the case, they said.
In the absence of any clear definition of 'major policy' decisions, the grey area exists as to what extent Verma's powers will be limited.
The CBI chief's advocate said there was no basis for the Central Vigilance Commission to pass such an order recommending to send him on leave.
Manish Kumar Sinha has also alleged that the complainant in the case, businessman Sana Sathish Babu, had told him that Union minister Haribhai Parthibhai Chaudhari had been paid bribes to the tune of several crores of rupees for alleged help in matters related to CBI.
A bench headed by Chief Justice Ranjan Gogoi ordered that the confidential CVC report be given to Verma in a sealed cover and asked him to respond to it by Monday, also in a sealed cover. It will take up the matter on Tuesday.
After taking over on Tuesday night, Rao overhauled the team probing allegations of corruption against Asthana, bringing in completely new faces, officials said.
