In October 1999, the USOC launched USADA and operations began on October 1, 2000. In 2003, one of USADA's first major undertakings was the revision of the then-current United States anti-doping policies in order to bring them into compliance with the newly adopted World Anti-Doping Code. One of the major adjustments made to the Code by USADA included reducing the standard of proof required in doping-related adjudication. Before modifications, the standard of proof was equal to that required in a United States court of law. After modification, USADA reduced the standard required to establish a doping violation to "comfortable satisfaction of a hearing body".
