Rajasthan Public Service Commission had a glorious past of nearly 70 years. During 1923, the Lee Commission had recommended setting up of a Central Public Service Commission in India, but it did not give much thought to the need of establishing similar commissions in provinces. It was left largely to the discretion of provincial Governments to recruit and exercise control over their Services, as they thought proper.
At the time of formation of Rajasthan, the institution of Public Service Commission existed in only three of the 22 covenanting states viz. Jaipur, Jodhpur and Bikaner. The successor administration after the merger of the princely states promulgated an ordinance on 16th August, 1949 establishing the Rajasthan Public Service Commission Ajmer which was published in Raj. Gazette at 20th August, 1949. In thrid para of point no. 1 of this ordinance, it is clearly mentioned that the Commission will come in to effect from the date on which notification regarding appointment is published in Govt. Gazette. However the notification regarding appointment was published in the Rajasthan Gazettee on 22th December, 1949 and it was on this date that RPSC came into effect. It provided for the abolition of the PSCs or other institution performing duties in the nature of those of a PSC in the constituent states. The ordinance also provided inter-alia, for the composition of the Commission, the staff and the functions of the Commission.
