“The package contains a notice about disagreement with WADA sanctions.”However, Ganus, who has long argued for a major crackdown by Russia against doping cheats, warned that the legal challenge could backfire. The formal statement of disagreement with WADA will trigger an appeal process against the ban at the Lausanne-based Court of Arbitration for Sport (CAS). WADA this month banned Russia for four years from major global events, including next year’s Tokyo Olympics and the 2022 FIFA World Cup in Qatar, over manipulated doping data. Ganus warned that contesting the ban could make matters worse, because CAS could make sanctions against Russia more severe. He referred to the position of US Anti-Doping Agency chief Travis Tygart, who has called for a blanket ban on Russian athletes at the Tokyo Olympics.
