MOSCOW (Reuters) - The Russian Olympic Committee appealed on Thursday against a Moscow court ruling that refused to recognize bobsledder Alexander Zubkov\u2019s Olympic ban, saying it could cast doubt on Russia\u2019s desire to fight against doping.

REUTERS\/Murad SezerZubkov, who has retired from competition and currently serves as the president of Russia\u2019s bobsleigh federation, was stripped of his two gold medals from the 2014 Sochi Olympics over doping. Yet a Moscow court last month refused to acknowledge a ruling by the Court of Arbitration for Sport (CAS) that confirmed a doping violation against Zubkov. The judgment has no effect outside the country, leaving the CAS ruling intact. The Russian Olympic Committee said that the Moscow court ruling \u201ccould give reason to doubt that Russia truly recognizes the basic principles of the fight against doping\u201d. When contacted by Reuters on Thursday, Zubkov said: \u201cThe Russian Olympic Committee has to defend its athletes ... but unfortunately our Olympic leaders don\u2019t agree. They are taking the side of the International Olympic Committee (IOC).\u201d The IOC stripped Zubkov of his two gold medals last year and banned him from the Olympics for life because of doping violations. Zubkov has denied any wrongdoing. He appealed to the CAS, but the court upheld the IOC decision. The Russian team was banned by the International Olympic Committee (IOC) from competing at this year\u2019s Pyeongchang Winter Games over the systematic manipulation of doping tests at the Sochi Olympics. The IOC, however, allowed Russians with no history of doping to compete in Pyeongchang at its invitation as neutral athletes.
