Under Article 320, the Commissions have the following functions:-

(2) To assist the States in framing and operating schemes of joint recruitment if two or more States request the Union Commission in his behalf;

Under Article 321, the functions of the Union Commission or a State Commission may be extended by an Act made by Parliament or the Legislature of the State concerned.
Such an Act may also bring within the scope of the functions of the Commission matters connected with the services of public institutions such as local bodies or public corporations under the Union or State Government.
This is important in view of the facts that as the activities of both the Union and the State Governments increase, more and more of public corporations and such other institutions are bound to be established involving the employment of an ever increasing number of officials.
