The establishment of the UPSC is governed by Articles 315 to 323 of the Indian Constitution. Article 315 outlines the establishment of a Public Service Commission for the union and states, which plays a crucial role in recruiting for civil services. Article 316 provides for the composition of the Commission while Article 317 details the conditions of service of the Commission members. These articles collectively ensure that the UPSC functions independently and effectively, providing merit-based recruitment for the Indian administrative framework.
