On July 30th Russian Swimmer Yulia Efimova filed an application with CAS against the IOC, ROC, and FINA. This application stated that the decision made that barred her from competing in the Olympics was “invalid and unenforceable”.
Although Efimova is not currently suspended from competition, a decision made by the IOC Executive Board regarding Russian Olympic qualifiers prevented her from competing. This decision came in light of accusations that the entire Russian federation was covering up positive doping tests made by the World Anti-Doping Assocation (WADA). It stated that the IOC would not accept entry of any Russian athletes unless they fulfilled a number of requirements, including never having been sanctioned for doping.
Efimova has tested positive for banned substances twice– once in 2013 and once earlier this year. She served a 16-month suspension for her positive test in 2013, but she was found as having “no fault” earlier this year after WADA was unable to determine how long the substance she tested positive for would remain in ones body after it was banned in January of this year. Efimova claimed that this criteria was unfair and unenforceable because it presumed guilt on her part for something she had earlier been found not at fault.
CAS ended up partially upholding Efimova’s application, ruling that the part of the IOC’s decision regarding previous doping sanctions was unenforceable. Although this decision did not force the IOC to do anything, Efimova was officially added to the Rio start lists. She will compete in the 100 and 200 m breastroke individually, and most likely be a member of Russia‘s 4×100 medley relay.
