The International Ice Hockey Federation filed an appeal against the decision to allow the Russians to participate in the tournaments.
The claim was sent to the Court of Arbitration for Sport.
The IIHF made this decision on the basis that two of the three judges who made the final ruling in the case had undisclosed business ties to Russia, Canadian TSN journalist Gord Miller said.
Earlier, the Swiss publication Inside Paradeplatz reported that the chairman of the jury, the Italian Giulio Palermo, attended a legal conference in Moscow in September 2026.
On October 30, CAS required the International Ice Hockey Federation to admit Russian teams to tournaments of the 2026/27 season.
