Advocate-General Bolai Roy said the CBI had started the investigation by registering a murder case, which amounts to the violation of the court’s order since the latter had ordered for a probe into the “unnatural death” of Rehman rather than his “murder”.

How could the CBI lodge an FIR for murder even before conducting the case, Roy said and urged the court to reject the report since it was tantamount to a contempt of court.

He further said the agency could have conducted the investigation without registering an FIR. If at all an FIR was necessary the CBI could have come up before the bench for permission. Referring to the report, Justice Dipankar Dutta said the agency had collected information from the writ petition before registering the FIR.
