the holding of the disciplinary proceedings and the criminal trial simultaneously, stay of disciplinary proceedings may be an advisable course in cases where the criminal charge against the employee is grave and continuance of the disciplinary proceedings is likely to prejudice their defence before the criminal court. Gravity of the charge is, however, not by itself enough to determine the question unless the charge involves complicated question of law and fact. The court examining the question must also keep in mind that criminal trials get prolonged indefinitely especially where the number of accused arraigned for trial is large as is the case at hand and so are the number of witnesses cited by the prosecution. The court, therefore, has to draw a balance between the need for a fair trial to the accused on the one hand and the competing demand for an expeditious conclusion of the ongoing disciplinary proceedings on the other. An early conclusion of the disciplinary proceedings has itself been seen by this Court to be in the interest of the employees." We have heard the learned counsel for the parties at some length. The only question that arises for consideration is no more res integra. It is well settled that there is no legal bar to the conduct of the disciplinary proceedings and criminal trial simultaneously. However, no straitjacket formula can be spelt out and the Court has to keep in mind the broad approach to be adopted in such matters on case-to-case basis. The contour of the approach to be adopted by the Court has been delineated in a series of decisions." The purpose of departmental enquiry and of prosecution are two different and distinct aspects. The criminal prosecution is launched for an offence for violation of a duty, the offender owes to the society or for breach of which law has provided that the offender shall make satisfaction to the public. So crime is an act of commission in violation of law or of omission of public duty. The departmental enquiry is to maintain discipline in the service and efficiency of public service.
