The World Anti-Doping Agency WADA has no idea of the exact whereabouts of the former chief of the Moscow anti-doping laboratory, Grigory Rodchenkov - the main informer of the author of the report on doping in Russian sports, Richard McLaren, WADA President Craig Reedie told TASS.
The McLaren report, an independent study commissioned by Wada, found evidence of state-sponsored doping.
Kirill Sveshnikov, Dmitry Strakhov and Dmitry Sokolov were unable to compete at the Rio 2016 Olympics after Russian athletes were banned.
An independent report by the World Anti-Doping Association (WADA) in 2016 accused Russian Federation of running a "state-sponsored doping program" to cover up positive drug tests for its athletes at major worldwide competitions.
They had launched an appeal before the Court of Arbitration for Sport (CAS) prior to the Olympics but lost. The Cyclists allege that as a result, they were banned from the 2016 Rio Olympics and suffered great reputational harm. Mr. Sveshnikov continued: "We are asking the Court to review all of the evidence and to vindicate us".
"WADA would expect the Russian authorities to take responsibility for this deliberate system of cheating that was uncovered by the McLaren Investigation - as is stipulated within RUSADA's Roadmap to Compliance - rather than continually shifting the blame onto others", WADA spokesperson Maggie Durand said. RUSADA was declared "non-compliant" with global sport's anti-doping code in November 2015 in the wake of the report by professor Richard McLaren which uncovered widespread doping in Russian sport.
Wada declined to comment on the lawsuit.
In May 2016, McLaren was tasked by Wada with investigating allegations of doping in Russian Federation. In terms of cycling, the decision was made by governing body the UCI.
