Cycling's governing body the UCI expressed their growing impatience on Thursday over the US Anti-Doping Agency's delay in handing over the Lance Armstrong doping dossier.
One month after USADA branded Armstrong a drugs cheat and stripped him of his seven Tour de France titles, the UCI are still waiting to examine for themselves the evidence compiled against the American cycling legend.
USADA announced on August 24 that Armstrong would be banned for life and his results since 1998 - including those seven Tour titles won from 1999-2005 - would be expunged due to "numerous" alleged violations.
But the USADA's jurisdiction is limited to the United States, leaving it up to cycling's rulers to endorse their decision to erase Armstrong's achievements from cycling's record books.
UCI president Pat McQuaid said: "The UCI has no reason to believe that a complete file does not exist, but the USADA's repeated inability to communicate its decision is beginning to concern us."
The Irishman added: "It's now more than one month that the USADA punished Lance Armstrong. We thought the USADA would have been better prepared before launching this process."
He noted that "according to media reports the delivering of this decision was held up because the organisation (USADA) is continuing to gather evidence and that it has still to complete the file."
"It seems that it would have been more useful for USADA to have used the time at its disposal during the Tour de France, the Olympic Games and the (cycling) road championships to prepare a complete dossier rather than issue statements," a clearly exasperated cycling chief said.
"The UCI learned of reports of delays from the press, and not by an official communication from USADA. The quicker the UCI receives the decision and the file the quicker it will be able to deliver its response," McQuaid's statement concluded.
Cancer survivor Armstrong said after USADA pronounced it was stripping him of his record that he would not seek to clear his name through independent arbitration, effectively throwing in the towel against what he regards as a witchhunt and pointing to the fact he never failed any of hundreds of dope tests.
Armstrong continues vehemently to deny doping during his career and had questioned USADA's authority to ban him but the agency says it has as many as 10 witnesses prepared to testify to the racer's drug use while adding it believes the UCI and Tour de France organisers should honour its findings under the World Anti-Doping Code.
