That is the minimum expected to ensure a clean and efficient administration and to protect the public interests. An employee found guilty of a misconduct cannot be placed on par with the other employees and his case has to be treated differently. There is, therefore, no discrimination when in the matter of promotion, he is treated differently. The least that is expected of any administration is that it does not reward an employee with promotion retrospectively from a date when for his conduct before that date he is penalised in praesenti. When an employee is held guilty and penalised and is, therefore, not promoted at least till the date on which he is penalised, he cannot be said to have been subjected to a further penalty on that account. A denial of promotion in such circumstances is not a penalty but a necessary consequence of his conduct. In fact, while considering an employee for promotion his whole record has to be taken into consideration and if a promotion committee takes the penalties imposed upon the employee into consideration and denies him the promotion, such denial is not illegal and unjustified. If, further, the promoting authority can take into consideration the penalty or penalties awarded to an employee in the past while considering his promotion and deny him promotion on that ground, it will be irrational to hold that it cannot take the penalty into consideration when it is imposed at a later date because of the pendency of the proceedings, although it is for conduct prior to the date the authority considers the promotion. ...”
