The Madrid Provincial Court dismissed appeals from Uefa, the Spanish football federation (RFEF), and LaLiga.
The court confirmed Uefa "seriously infringed the European Union's free competition rules" by abusing its dominant position in blocking the Super League.
This ruling aligns with a December 2023 decision by the Court of Justice for the European Union (CJEU), which found Uefa's original rules to block the competition were contrary to EU law.
Uefa stated the ruling does not validate the abandoned Super League project nor undermine its current authorisation rules, which remain fully in force.
