The International Cycling Union says it will wait for the U.S. Anti-Doping Agency to explain why Lance Armstrong should lose his seven Tour de France titles before commenting on the case.
The sport's governing body says it wants USADA to "submit to the parties concerned (Mr. Armstrong, WADA and UCI) a reasoned decision explaining the action taken."
The UCI says the World Anti-Doping Code requires USADA to do this in cases "where no hearing occurs."
Armstrong has chosen not to pursue an arbitration hearing where he could have fought charges brought by U.S. anti-doping officials that his teams doped when he won the Tour from 1999-2005.
The UCI and USADA have engaged in a turf war over who had jurisdiction for the case.
The superstar cyclist, whose stirring victories after his comeback from cancer helped him transcend sports, chose not to pursue arbitration in the drug case brought against him by the U.S. Anti-Doping Agency saying he'd had enough.
Armstrong clearly knew his legacy would be blemished by his decision. He said he has grown tired of defending himself in a seemingly never-ending fight against charges that he doped while piling up more Tour victories than anyone ever. He has consistently pointed to the hundreds of drug tests that he passed as proof of his innocence during his extraordinary run of Tour titles from 1999 to 2005.
"There comes a point in every man's life when he has to say, 'Enough is enough.' For me, that time is now," Armstrong said Thursday night, hours before the deadline to enter arbitration. He called the USADA investigation an "unconstitutional witch hunt."
