In this context, it is relevant to consider G.O.Ms.No.257 General Administration (Ser.C) Department, dated 10.06.1999, wherein it is stated that the appointing authority should consider and decide whether it would not be against public interest to allow adhoc promotion to the officer concerned and the same shall decide with reference to the charge under enquiry. It is stated that if the charge is one of moral turpitude, misappropriation, embezzlement and grave dereliction of duty, then the appointing authority should consider whether it is not in the public interest to consider adhoc promotion to such charged officer or not. It is further stated in the said G.O. that if the charge is not a grave one, but is a minor one, not involving moral turpitude, embezzlement and grave dereliction of duty, then in all such cases the appointing authority should consider that it would not be against public interest to allow adhoc promotion because till then his record is clean with reference to ACRs. It is further stated that the appointing authority should finalise the disciplinary cases within two years and shall conclude the same by issuing final orders to that effect.
