The formal complaint against Armstrong appears to rely heavily on evidence and statements supplied by Landis and gathered by the U.S. Anti-Doping Agency for its 2012 investigation that exposed a doping program on the USPS team. Armstrong has been banned from sports for life and stripped of his seven Tour de France victories.
Bruyneel, who lives in London, also has been charged by USADA with doping violations but is fighting that case in arbitration.
The government notes the contract with the Postal Service required riders to follow the rules of cycling, which included bans on performance-enhancing drugs and methods. Armstrong now admits using steroids, blood boosters and other illegal performance-enhancing drugs and measures to win.
The complaint said that for years, team officials assured the Postal Service that the team wasn’t doping.
Armstrong had been the target of a federal criminal grand jury, but that case was closed without charges in February 2012. Armstrong has previously tried to settle the Landis whistleblower lawsuit, but those talks broke down before the government announced its intention to join the case.
Armstrong also is fighting a lawsuit from Dallas-based promotions company SCA to recover about $12 million it paid him in bonuses, and a lawsuit from the London-based Sunday Times, which wants to get back $500,000 it paid him to settle a libel case.
