The CBI has made much of sanctions to prosecute public servants like Maharashtra's ex chief minister Ashok Chavan using the Governor's office but was the nod really necessary? CBI file notings, accessed by Outlook, clearly show that officers investigating the Adarsh scam, in which Chavan is an accused, had staunchly opposed the need for seeking sanction. Chavan was chargesheeted for cheating, conspiracy and misuse of office "which do not have any nexus with discharge of duty of any public servant", the Directorate of Prosecution of the CBI had said in 2012.
