The attorney for cyclist Floyd Landis took aim at the International Cycling Union, accusing the federation of a breach of ethics for leaking the results of the Tour de France winner's positive drug test.

Attorney Howard Jacobs said Wednesday it should be "strongly noted" that no formal charges against Landis have even been filed.

"I am troubled by the actions of the UCI and how they have spoken out about this case, which is in direct contravention of the UCI's own rules and the World Anti-Doping Code," he said in a statement from his office in Southern California. "While there has been much speculation and reporting as to the cause of the "A" positive, the fact remains that the "B" sample has not been tested."

Results of the second, or "B," sample are expected to be released Saturday, and if that sample is positive, the results will be sent to the U.S. Anti-Doping Agency, which would handle the case.

Landis showed a testosterone imbalance in an initial urine sample taken during the Tour de France. Both "A" and "B" samples were provided July 20 after he sped his way back into contention by winning a tough Alpine leg of the multistage race.

Last Wednesday, the UCI, cycling's governing body, revealed that an unidentified cyclist had tested positive, but it refused to release the name until the backup sample had been tested. The next day, Landis' Phonak team said it was Landis who tested positive.

Jacobs said the UCI should have known the name would become public once the announcement of a positive test was made "due to the confidentiality breaches that have been previously noted by many at the French laboratory" where the testing took place.

The attorney also cited a New York Times report that said a carbon isotope ratio test had detected synthetic testosterone in Landis' system. The Times attributed the report to a person inside the UCI with knowledge of the results.

"This raises even more concerns, particularly following the provisional suspension earlier this year of a high-ranking UCI official for leaking documents and-or information to" the French newspaper, L'Equipe, Jacobs said.

Landis' doctor, Brent Kay, confirmed the finding on the CIR test to the Times, though in Jacobs' eyes, that did not make the UCI's leak OK.

"Let's be clear, the UCI are the ones who said the CIR test was positive," Jacobs told The Associated Press.

The attorney said he had seen no proof of the positive CIR test.

"While there is an allegation that the CIR is positive, they don't provide documentation that backs that up," he said. "To say I agree with that conclusion, I can't do that, because I haven't seen the documents."

The CIR test could prove even more damaging than the elevated testosterone-epitestosterone ratio discovered in Landis' "A" sample. That's because the CIR tests detect the presence of synthetic testosterone, meaning it was introduced by an outside source.
