10. So far as the second type of cases are concerned the proof of grave misconduct on the part of the government servant concerned during his service tenure will have to be culled out by the revisional authority from the departmental proceedings or judicial proceedings which might have taken place during his service tenure or from departmental proceedings which may be initiated even after his retirement in such type of cases. But such departmental proceedings will have to comply with the requirements of Rule 43(b). Consequently a retired government servant can be found guilty of grave misconduct during his service career pursuant to the departmental proceedings conducted against him even after his retirement, but such proceedings could be initiated in connection with only such misconduct which might have taken place within 4 years of the initiation of such departmental proceedings against him. In the present case, the respondent retired on 31-1-1993 and the show-cause notice was issued on the ground of grave misconduct on 27-9-1993 and not on the ground that service record of the pensioner was not thoroughly satisfactory. It was issued by the State Government as sanctioning authority. It had, therefore, to be read with Rule 43(b). Such notice therefore, could cover any misconduct if committed within 4 years prior to 27-9-1993 meaning thereby it should have been committed during the period from 26-91989 up to 31-1-1993 when the respondent retired. Only in case of such a misconduct, departmental proceedings could have been initiated against the respondent under Rule 43(b). In such proceedings, if he was found guilty of misconduct he could have been properly proceeded against under Rule 139(a) and (b). On the facts of the present case it must be held, agreeing with the High Court that the notice dated 27-9-1993 invoking powers under Rule 139(a) and (b) was issued wholly on the ground of alleged past misconduct and was not based on the ground that service record of the respondent was not thoroughly satisfactory. So far as that ground was concerned, on a conjoint reading of Rule 43(b) and Rule 139(a) there is no escape from the conclusion that as the alleged misconduct was committed by the respondent prior to 4 years from the date on which the show-cause notice dated 27-9-1993 was issued, the appellant authority had no power to invoke Rule 139(a) and (b) against the respondent on the ground of proved misconduct. Consequently, it had to be held that proceedings under Rule 139 were wholly incompetent. The High Court was equally justified in quashing the final order dated 13-12-1993 as there is no proof of such a misconduct. No question of
