Osasuna have been fined and provisionally excluded from the next UEFA club competition they qualify for because they filed a sports-related claim to the wrong court, UEFA said on Thursday.
UEFA cleared Osasuna to play in the 2023-24 Conference League playoff round in July after they were initially excluded from the competition due to a match-fixing scandal from a decade ago.
However, the body said it had opened separate disciplinary proceedings against the LaLiga club for filing a claim to the ordinary state courts in Pamplona, Spain rather than the Court of Arbitration for Sport (CAS).
UEFA has fined Osasuna 100,000 euros ($109,000) and excluded them from the next UEFA club competition for not respecting the exclusive jurisdiction of CAS.
Osasuna, who finished seventh in La Liga last season and will play their playoff round games on Aug. 24 and 31, said they would not appeal against UEFA's decision.
