A Division bench headed by Chief Justice Vikramajit Sen also appointed advocate Clifton D Rozario as amicus curiae to assist the court in the case.
"From the articles appearing in various newspapers, it is evident that there is scepticism, if not suspicion in the minds of public at large with regard to the enquiry that is being conducted on the unfortunate fatal attack on late Mahantesh, who was conducting audit of House Building Co-Operative Societies," it said.
"Keeping all the dimensions of the death of KAS officer in perspective, we exercise suo motu power and issue notice to Principal Secretary to Home department as well as Commissioner of Police returnable by June 21, 2012," the bench said. 48-year-old Mahantesh, said to be a whistle-blower in controversial land allotments by societies, suffered head injuries in an alleged attack by unidentified persons on May 15, and died in a private hospital here five days later.
Mahantesh was working as Deputy Director of the audit wing in the state's Cooperative department and had reported irregularities in different societies involving some officials and political figures.
