CBI has asked the Attorney General to oppose any move in the Supreme Court on Friday allowing a Special Public Prosecutor to vet its closure reports in coal blocks allocation scam before their being filed before a trial court. CBI sources said the agency is not willing to accept any such move claiming it will not be in accordance with CrPC and working of CBI because final reports, which could be charge sheets or closure reports, can only be seen by the trial court. The agency has briefed the Attorney General and the Solicitor General to oppose any such move in the Supreme Court, they said. The sources said while preliminary enquiries can be closed internally in case of FIRs closure reports can be filed only before the trial court which may accept or reject.
