Proceedings against Barcelona, Juventus and Real Madrid have been declared “null and void”, UEFA said.
The three clubs had argued in court UEFA’s attempt to punish them for setting up a breakaway league was against European competition law.
UEFA says it is now “as if the proceedings had never been opened”.
UEFA will also contact the other nine clubs involved in the attempted breakaway to tell them they will no longer need to pay the fines imposed on them for trying to set up the ESL in April.
The nine clubs are Arsenal, Chelsea, Liverpool, Manchester City, Manchester United, Tottenham Hotspur, Atletico Madrid, AC Milan and Inter Milan.
In May the nine clubs agreed to pay a combined fine of €15m and to have five per cent of their UEFA competitions revenues withheld for one season.
