In a statement responding to losing the 2023 WJC hosting rights and its teams being banned from competition, Russian Hockey Federation says IIHF's decision is "discriminatory and contrary to the spirit of the sport." RHF disagrees with decision and reserves right to appeal.
While IIHF is one piece, many member nations have already announced separately they will not compete against Russian teams at any tournament until further notice. They can appeal all they want, they still won't find credible opponents willing to play them.
