WADA president Dick Pound was quick to accuse Lance Armstrong of doping (a claim contested by WADA's second-in-command) and eager to dodge UCI questions about the lab in question but he has said little about the claim that WADA's own doping protocols were breached by the lab.
Oswald and Bubka's joint letter accuses the Chatenay-Malabry laboratory of violating "confidentiality regulations".
L'Equipe, the newspaper which started the 'Armstrong affair', has been provided with a copy of the letter.
It said: "According to the world code, that laboratory should have ensured the anonymity of the samples used in their research, or asked the athletes concerned for permission to perform (post) analyses. It's not a question of protecting anyone, but of applying the rules."
WADA's scientific director Olivier Rabin has said no rules had been broken nor any standards breached.
