Behind closed doors, and mainly via video links from outside of China, legal teams for the groups appealing that decision will make their arguments before the panel, which is led by a London-based American lawyer. Matthieu Reeb, the CAS general secretary, said Valieva would provide testimony by video link; that kind of personal touch is a measure Russia has used in past hearings to personalize the plight of individual athletes in eligibility cases.
The hearing is expected to last as long as six hours — well into the early hours of Monday morning in Beijing. Once it is complete, the judges will most likely have a short discussion among themselves before retiring for the night and reconvening on Monday to complete their deliberations.
The panel expects to inform the parties, and announce its decision, on Monday afternoon in Beijing, one day before Valieva is — for now — scheduled to compete in the women’s short program.
The stakes of its decision for the Olympics and the global fight against doping could not be higher. As a Russian, Valieva is competing for a nation that is not able to compete under its own name or flag as part of a multiyear ban related to a state-led doping scheme that sought to corrupt results at the 2014 Sochi Olympics.
But none of that will be part of Sunday’s discussion. There also will be little discussion about how the banned heart medication, trimetazidine, ended up in Valieva’s system, or why it took more than six weeks for the results of a test submitted in December to be confirmed.
