In M.S. Bindra Vs. Union of India and Others[(1998) AIR(SC) 3058], it was held:
While evaluating the materials the authority should not altogether ignore the reputation in which the officer was held till recently. The maxim “Nemo Firut Repente Turpissimus” (no one becomes dishonest all on a sudden) is not unexceptional but still it is salutary guideline to judge human conduct, particularly in the field of Administrative Law. The authorities should not keep the eyes totally closed towards the overall estimation in which the delinquent officer was held in the recent past by those who were supervising him earlier. To dunk an officer into the puddle of “doubtful integrity” it is not enough that the doubt fringes on a mere hunch. That doubt should be of such a nature as would reasonably and consciously be entertainable by a reasonable man on the given material. Mere possibility is hardly sufficient to assume that it would have happened. There must be preponderance of probability for the reasonable man to entertain doubt regarding that possibility. Only then there is justification to ram an officer with the label ‘doubtful integrity’.
