MarkvW said:I think that it is debatable whether there "has to be" a strict liability ban. Strict liability has come to be because the riders are powerless and can't/won't demand individual rights in exchange for their bike riding services. If the riders ever got unionized you'd see a fairer process (and a dirtier peloton).
It may be debatable whether there has to be 'strict liability' with the doping cases, but in the case of Contador and the Clenbuterol, it is strict liability. Since he was unable to show how the Clenbuterol got into his system through a non-negligent manner, then the ban is appropriate. Debate on the strict liability is probably worth its own thread.
