LAUSANNE, Switzerland -- The Spanish football league is challenging FIFA's decision to switch the 2022 World Cup in Qatar to November-December.
The Court of Arbitration for Sport says the Spanish league (LFP) has filed an appeal against the FIFA decision, which avoids the Qatari summer heat.
The court has not set a hearing date.
A November-December tournament would shut down top European leagues for eight peak weeks and require more summer fixtures.
It is the first formal legal challenge to moving the World Cup in Qatar from the traditional June-July slot.
FIFA's executive committee approved the change in March, 18 months after requesting a global consultation.
The Spanish league is a member of the European Professional Football Leagues group, which was consulted.
FIFA rejected a European clubs and leagues proposal to play in May-June.
