Under the Government of India Act, 1935, it was reorganised as the Federal Public Service Commission. The Constitution gave UPSC constitutional status through Articles 315–323, with Article 320 laying down its principal functions. UPSC conducts the Civil Services Examination for services such as the IAS, IPS and Indian Forest Service.
