into promptly. The disciplinary proceedings are meant not really to punish the guilty but to keep the administrative machinery unsullied by getting rid of bad elements. The interest of the delinquent officer also lies in a prompt conclusion of the disciplinary proceedings. If he is not guilty of the charges, his honour should be vindicated at the earlist possible moment and if he is guilty, he should be dealt with promptly according to law. It is not also in the interest of administration that persons accused of serious misdemeanour should be continued in office indefinitely, i.e., for long periods awaiting the result of criminal proceedings. It is not in the interest of administration. It only serves the interest of the guilty and dishonest. While it is not possible to enumerate the various factors, for and against the stay of disciplinary proceedings, we found it necesasry to emphasise some of the important considerations in view of the fact that very often the disciplinary proceedings are being stayed for long periods pending criminal proceedings. Stay of disciplinary proceedings cannot be, and should not be, a matter of course. All the relevant factors, for and against, should be weighed and a decision taken keeping in view of the various principles laid down in the decisions referred to above." This decision has gone two steps further to the earlier decisions by providing :The 'advisability', 'desirability' or 'propriety' of staying the departmental proceedings "go into the scales while judging the advisability or desirability of staying the disciplinary proceedings" merely as one of the factors which cannot be considered in isolation of other circumstances of the case. But the charges in the criminal case must, in any case, be of a grave and serious nature involving complicated questions of fact and law. (2) One of the contending considerations would be that the disciplinary enquiry cannot -- and should not be -- delayed unduly. If the criminal case is unduly delayed, that may itself be a good ground for going ahead with the disciplinary enquiry even though the disciplinary proceedings were held over at an earlier stage. It would not be in the interests of administration that persons accused of serious misdemeanour should be continued in office indefinitely awaiting the result of criminal proceedings. In another case, namely, Depot Manager, Andhra Pradesh State Road Transport Corporation vs. Mohd. Yousuf Miyan (1997) 2 SCC 699 = AIR 1997 SC 2232, again it was held that there is no bar to proceed simultaneously with the departmental inquiry and trial of a criminal case unless the charge in the criminal case is of a grave nature involving complicated questions of fact and law.
