The establishment of the UPSC is mandated by Article 315 of the Indian Constitution. This article empowers the President of India to establish a Public Service Commission for the Union and for each state. The commission's primary role is to conduct examinations for appointments to the civil services and advise the government on matters related to the recruitment and promotion of personnel within these services. This constitutional provision underscores the significance of UPSC in maintaining an efficient and impartial administration.
