Lance Armstrong drops request for temporary restraining order against USADA Lance Armstrong dropped his request for a temporary restraining order against the U.S. Anti-Doping Agency Wednesday morning after the agency agreed to a 30-day extension of its Saturday deadline to respond to its anti-doping charges, Armstrong attorney Tim Herman said in a statement. With the deadline removed, Armstrong will await a ruling on the merits of the lawsuit he filed Tuesday against USADA. Agency chief Travis Tygart said USADA granted the extension to allow time for the judge to decide whether to dismiss the suit or make another ruling. "USADA believes this lawsuit like previous lawsuits aimed at concealing the truth, is without merit," Tygart said in a statement. He also said the agency was "confident the court will continue to uphold the established rules which are compliant with federal law and were approved by athletes, the U.S. Olympic Committee, and all Olympic sports organizations." U.S. District Court Judge Sam Sparks, who was assigned to the case, has been notified of the 30-day extension, according to another person involved in Armstrong's case. In his suit, Armstrong claims USADA broke its own rules, possibly violated federal laws and ignored his constitutional rights in setting a deadline by which he must either submit to arbitration or immediately be stripped of his seven Tour de France titles and banned for life from sport. USADA has argued that its rules are fair and have been approved by various Olympic movement constituents, including athletes. In a June 12 letter, USADA charged Armstrong and five other non-riding former team members with engineering a massive doping conspiracy. Armstrong, who says he has been tested more than 500 times during his career, has never flunked a drug test and says he is innocent of the charges.
