Under Article 315, each constituent State of the Union should have a Public Service Commission. There is however provision for setting up Joint Public Service Commissions each serving more than one State.
But such Commissions may be set up only by the law of Parliament on a request for the same by the States concerned. The Constitution also permits the Union Public Service Commission to render its services to a State, for all or any of the needs of the State, with the approval of the President.
The members of a State Public Service Commission are appointed by the Governor, and those of a Joint Commission by the President. As in the case of the Union Commission, the appointment is for a maximum period of six years.
But if a member attains the age of 62 years while in service, irrespective of his having completed six years he must retire from service. The members of State and Joint Public Service Commissions are not eligible for any appointment under the Union or the States except that a Chairman may become the Chairman or a member of the Union Public Service Commission or the Chairman of any other State or Joint Service Commission and a member may, in addition to the above mentioned offices, become the Chairman of the Commission of which he is a member.
The conditions of service of the members of the State Public Service Commissions are more or less the same as those of the Union Commission. The only significant point of difference is in salary which varies from State to State.
The conditions of service of a member of a State Public Service Commission may not be varied to his disadvantage after his appointment. The number of members on the State Commissions also varies from State to State.
The basis and the procedure for the removal of the members of the State or Joint Commissions are the same as for the members of the Union Public Service Commission.
