CBI sources said although the three Gujarat ministers, who were questioned by the agency in connection with the alleged meeting, have admitted taking part in the meeting but the agency cannot take their statements on face value.
The sources said it is seeking legal opinion whether their statements can be the basis of proceeding with a chargesheet against them or further material evidence was needed. They said the agency is also probing whether the ministers took steps to shield the police officials or discussions recorded by one of the accused was just off-the table conversations.
The CBI had recently questioned former Gujarat Minister of Law Bhupendrasinh Chudasama, Minister of state for Law Pradeepsinh
Jadeja and former Minister of State for Home Praful Patel who had allegedly attended the purported meeting.
Suspended Indian Penal Service officer G L Singhal, who was among the nine persons who attended the meeting, had submitted two pendrives to investigators containing the recorded conversations of the meeting.
Singhal is now out on bail as the agency failed to file the chargesheet against him in the stipulated 90 days.
The nine people who were allegedly present in the meeting held in the private chamber of Advocate General Kamal Trivedi were Singhal, Singhal's lawyer friend Rohit Verma, G C Murmu, A K Sharma, then MoS (home) Praful Patel, Jadeja, Chudasama and another accused in the Ishrat case, Tarun Barot.
