Wenger Vieli with Bulgarian Football Union before the Federal Supreme Court

Wenger Vieli represented the Bulgarian Football Union (BFU) in three appeals before the Swiss Federal Supreme Court, against arbitration decisions by the Court of Arbitration for Sports (CAS).

The context

The BFU argued that the CAS – and likewise the Players’ Status Chamber of the FIFA Football Tribunal – wrongly affirmed its jurisdiction to hear three labor law claims brought by former coaches against the BFU.

In its judgments of January 27, 2026, the Federal Supreme Court ruled that the FIFA PSC and the CAS lacked jurisdiction to decide the dispute in the absence of an arbitration agreement. The Federal Supreme Court upheld the BFU’s appeals, annulled the arbitration awards and remanded the cases to the CAS with the instruction to set aside the previous decisions of the FIFA PSC.
