The American has always denied doping.The Texas court ruling means Armstrong will now have to face the doping charges. He could lose his record-breaking seven Tour de France titles if found guilty, and banned from cycling.Despite his dismissal of Armstrong’s case against the USADA, US District Judge Sam Sparks noted "troubling aspects” of the agency’s case.He remarked upon the contrast between the USADA’s determination to pursue with the hearing "in direct conflict with [international cycling governing body] UCI’s equally evident desire not to proceed against him”.
