The Court of Arbitration for Sport (CAS) said on Wednesday it has received 22 appeals from Russian athletes against bans handed out for doping offences at the 2014 Sochi Winter Olympics.
The disciplinary commission of the International Olympic Committee (IOC) had found the athletes violated anti-doping rules and barred them from the events in which they participated and forfeited all medals they had won.
The athletes were also banned from taking part in any future Olympic games. Lausanne-based CAS said the athletes had requested a final decision be made before the start of next year's winter games in South Korea.
The IOC on Tuesday banned Russia from the event, citing evidence of a widespread doping regime.
