According to this scheme all categories of government employees are entitled to upgradation of pay on completion of 10, 18 and 26 years of service. The ACP scheme applicable to all government employees was modified by means of the Government Order dated 05.11.2014 wherein it was provided that they shall be entitled to upgradation of pay on satisfactory completion of 8, 16 and 24 years of service. Thus, so far as the members of PMHS are concerned, they have been provided different scheme for Career Progression known as SACP, whereas the respondent-petitioner has been provided the benefit of general Assured Career Progression scheme applicable to all other government servants. The general ACP Scheme offers upgradation of higher scale of pay only to those eligible government servants who are deprived of regular promotion to higher post for some reason. The scheme, thus, compensates such deprived lot of government servants by grant of monitory benefit on personal basis which does not amount to regular promotion and also does not require creation of availability of any new posts. The financial upgradation, thus, is available only if regular promotion during the prescribed period is not availed by the government servants.
