The petitioners have sought appointment of a regular chief of the agency.They also want all records of deliberations and rational criteria related to short-listing and selection of the CBI director to be made available under the transparency law.They have also asked for the entire process of selection, including the composition of the panel, its mandate and minutes of the meeting of the search committee to be made public.Alok Verma and his deputy, CBI special director Rakesh Asthana, were engaged in a feud that affected the agency’s functioning. Asthana levelled charges of corruption against Verma in a letter to the cabinet secretary in August last year.The probe agency filed a first information report (FIR) against Asthana in October last year. On the intervening night of October 23 and 24, the government divested both of their powers. Rao took charge as the interim director for the first time on the intervening night of October 23 and 24.Verma challenged the government order in the top court and it conditionally reinstated him as the CBI chief on January 8, saying that only the selection panel could remove him. The panel decided by a majority decision of 2-1 to remove Verma on January 10.The panel, which also comprises leader of the largest opposition party in the Lok Sabha, Mallikarjun Kharge of Congress, and CJI Gogoi had however removed Verma as the chief within a few days of the verdict.Rao, who was appointed as interim chief of the premier investigation agency in October when Verma and his deputy were sent on leave, was re-appointed as the interim chief of the agency.The government meanwhile has initiated the process of looking for Verma’s successor.
