Judges have ruled that UEFA rules blocking the formation of such a competition were contrary to EU law, boosting the prospect of a future European Super League.
The court has now ruled that UEFA and FIFA rules granting prior approval for new competitions are contrary to EU law, but added that the competition may still not be approved.
The Grand Chamber of the European Court of Justice had been asked to decide whether UEFA and FIFA acted against competition law by blocking the formation of the European Super League in 2021 and then seeking to sanction the clubs involved.
A release issued by the court said such rules were “contrary to competition law and the freedom to provide services”.
A non-binding decision delivered by the Advocate General in the case last December found rules allowing UEFA to have prior approval of new competitions were compatible with EU law.
