Advocate Prashant Bhushan, appearing for the NGO, said Asthana's appointment was illegal as his name had surfaced in a diary recovered during a raid conducted by the Income Tax department.
Earlier in August, the CBI's Delhi Unit had registered a FIR against three senior Income Tax Commissioners for accepting bribes from the Gujarat-based Sterling Biotech and Sandesara Group of Companies.
On Sunday, Gujarat cadre Indian Police Service (IPS) officer Rakesh Asthana was appointed as the special director of the Central Bureau of Investigation (CBI).
