PYEONGCHANG (Reuters) - The decision by the Court of Arbitration for Sport (CAS) to overturn lifetime Olympic bans on 28 Russian athletes came as a complete surprise and it could make the fight against doping more difficult, said IOC President Thomas Bach on Sunday.
CAS said on Thursday there was insufficient evidence of anti-doping violations against the athletes, and while it confirmed 11 other Russians had committed doping offences it reduced their lifetime bans to a suspension from this month's Pyeongchang Winter Games.
