Rajasthan Public Service Commission had a glorious past of nearly 50 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. It was published in Raj. Gazette at 20th August, 1949 and it came into effect from this date. 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.
Initially the composition of the Commission was one Chairman and 2 Members. Sir S.K.Ghosh (also the then Chief Justice of Rajasthan) was appointed Chairman. Subsequently Shri DeviShankar Tiwari and Shri N.R.Chandorkar were appointed Members and Shri S.C. Tripathi (I.E.S), formerly a member of the Federal PSC was appointed as Chairman. In the year 1951, in order to regulate the working of the Commission, the Rajpramukh issued the following Regulations under the provisions of the Constitution of India.
