Swiss club FC Sion said yesterday it has filed a suit against UEFA at the European Commission over the disqualification of its players that led to the club’s exclusion from the Europa League.

FC Sion were thrown out of the tournament on September 2 after being found guilty of fielding ineligible players, with Scottish club Celtic handed their place in the group stages despite losing the play-offs 3-1 on aggregate.

The Swiss side had taken the case to several regional courts which found in its favour.

UEFA has so far not complied with the Swiss court ruling but said it would comply with a ruling by the Court of Arbitration for Sport (CAS), due to deliberate on November 24.

FC Sion’s complaint claims that UEFA violated rules, including the “right of access to an independent and impartial judge” as well as the free movement of workers under the EU-Swiss treaty.

“Two Swiss jurisdictions have ruled in our favour but UEFA continues to openly violate these two decisions and insist that the CAS has the last say,” said Christian Constantin, president of the club.

“As a result we have been constrained to bring this case before the EU justice,” he added.
