Landis appealed to the USA Cycling and saying the tests were not done properly. USA Cycling asked three people from the United States Anti-Doping Agency (USADA) to study Landis's claims. On 20 September 2007 that group voted 2 to 1 against him. Landis was stripped of his title as winner of the 2006 Tour de France by the UCI, and banned from professional racing for two years.
