The Court of Arbitration for Sport (CAS) has dismissed the appeal filed by the Football Association of Serbia (FAS) against the Union des Associations Européennes de Football (UEFA). FAS sought to annul a resolution passed at the UEFA Congress held in Budapest on 3 May 2016 in which the Football Federation of Kosovo (FFK) was admitted as the 55th member association of UEFA. As a consequence, the resolution remains in force and FFK’s admission as a member association of UEFA is confirmed. In its appeal to the CAS, FAS argued that UEFA breached its own rules in admitting FFK as a member association and that such breaches meant that FFK’s membership contract should be declared null. 

But CAS ruled that although UEFA's statutes were ambiguous, Kosovo was recognized by the majority of United Nations member states as being an "independent state" and was therefore entitled to admittance.

UEFA’s decision on May 2016 led to Kosovo joining FIFA one week later, and being fast-tracked into a 2018 World Cup qualifying group.
