Had the IAAF ban been thrown out by CAS and the Russian track athletes let back in, that would seemingly have ruled out the IOC imposing a blanket ban. The Russians argued against a collective ban of its track athletes, saying it punishes those who have not been accused of wrongdoing. With the track ban upheld, however, the option remains open. The three-person panel ruled that the Russian Olympic Committee "is not entitled to nominate Russian track and field athletes to compete at the Rio 2016 Olympic Games considering that they are not eligible to participate under the IAAF competition rules." CAS, however, said it had no jurisdiction on whether the International Olympic Committee can accept or refuse the entry of Russian track and field athletes, either those representing their country or as "neutral athletes."
