The working of UPSC is governed by various legal provisions, primarily through the Constitution of India under Articles 315 to 323. These articles establish the UPSC and outline its functions, powers, and the procedures for recruitment and selection of candidates for various civil services positions. Additionally, the UPSC Act of 1950 and relevant rules formulated by the government further dictate the commission's operational framework. This legal framework not only ensures the quality and integrity of the selection process but also defines the rights and responsibilities of the commission and the candidates.
