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.Earlier in the day, Russia reacted to the ban saying it was insulting and has come from external pressure.”The IOC decision is offensive and insulting. It is completely unjustified,” Alexei Kravtsov, president of the Russian Skating Union, told R-Sport agency.His counterpart at the Russian curling federation, lawmaker Dmitry Svishchev, accused the IOC of having succumbed to external pressure when making its decision.”I consider that the IOC’s decision is unprofessional,” Svishchev told Reuters. “I am profoundly convinced that it was made under pressure. Someone needed Russia not to participate in the Games.”Bobsleigh federation president Alexander Zubkov, who was stripped of his two gold medals from the 2014 Sochi Games and banned for life from the Olympics last month, told Reuters he was shocked by the IOC decision.”I am simply shocked by what is happening and what happened and by (IOC President) Thomas Bach’s decision regarding our country and our athletes.”advertisementMore than 20 Russian athletes have been banned for life from the Olympics in the past few weeks over doping violations at the 2014 Sochi Games.The bans came as a result of an IOC investigation into allegations of widespread doping among Russians and sample tampering by laboratory and security officials at the Sochi Olympics.The Russian authorities have repeatedly denied state involvement in doping and pledged to work with international sports bodies to curb the use of banned performance-enhancing drugs in the country.
