duty. The departmental inquiry is to maintain discipline in the service and efficiency of public service. It would, therefore, be expedient that the disciplinary proceedings are conducted and completed as expeditiously as possible. It is not, therefore, desirable to lay down any guidelines as inflexible rules in which the departmental proceedings may or may not be stayed pending trial in the criminal cases against the delinquent officer. Each case requires to be considered in the backdrop of its own facts and circumstances. There would be no bar to proceed simultaneously with departmental inquiry and trial of a criminal case unless the charge in the criminal trial is of grave nature involving complicated questions of fact and law. Offense generally implies infringement of public duty, as distinguished from mere private rights punishable under criminal law. When the trial for a criminal offense is conducted it should be in accordance with proof of the offense as per the evidence defined under the provisions of the Indian Evidence Act, 1872 [in short ‘the Evidence Act’]. The converse is the case of departmental inquiry. The enquiry in a departmental proceeding relates to conduct or breach of duty of the delinquent officer to punish him for his misconduct defined under the relevant statutory rules or law. That the strict standard of proof or applicability of the Evidence Act stands excluded is a settled legal position. … Under these circumstances, what is required to be seen is whether the departmental inquiry would seriously prejudice the delinquent in his defense at the trial in a criminal case. It is always a question of fact to be considered in each case depending on its own facts and circumstances.”
