ボスマン判決
In the European Union, the 1995 Bosman ruling by the European Court of Justice established the right of free agency for association football players in all EU member nations. The Bosman ruling has since been extended to cover other professional sports and players from Eastern Europe. Players were still tied to their clubs unless their contract ran out until the Webster ruling allowed players the opportunity to move between nations, though it does not allow free players to move within the national league in which they currently play.
