Ukraine's National Olympic Committee has filed an appeal with the Court of Arbitration for Sport over the International Olympic Committee's decision to provisionally reinstate Russia to its competitions.
The move escalates a dispute over Russia's return to the Olympic framework, with Ukraine formally asking sport's top arbitration body to review the IOC's ruling. The appeal shows that Ukraine is seeking a legal route rather than limiting its response to public criticism.
At the center of the case is the IOC's decision to allow Russia back on a provisional basis. Ukraine is challenging that step and wants the Court of Arbitration for Sport to examine whether the reinstatement should stand.
The case now shifts to CAS, which handles major international sports disputes. Its review will determine how the challenge proceeds and could become an important development in the wider debate over Russia's place in global sport.
