As per instructions dated 25.04.1972, the Government had decided to introduce 10% posts from the pool of Clerks occurring in a particular year for promotion to Class IV employees. As per circular, there was certain conditions to be filled by Class IV employee for being appointed as Clerk in 10% reserved posts such as three years' service experience. The adhoc promotion or temporary promotion were made in anticipation on regular selection by S.S. Board against the Class III regular posts. However, the Government was to appoint on regular basis Class IV employees as Clerk after they fulfilling certain conditions, which was to be examined by the Departmental Selection Committee. Therefore, the date of adhoc promotion does not give right to the petitioners to seek their regularization. The Department has followed the instructions dated 25.04.1972 and has considered the case of all Peons and then regularized their adhoc promotion as Clerks. No one has has been discriminated by giving benefit of regularization from the date of adhoc promotion.
