Question juridique clé
Whether the player had validly waived the right to appeal the CAS award
Solution extraite
The written waiver signed by the player satisfied the formal requirements of Article 192 LDIP, but it could not be opposed to him in these sports-disciplinary circumstances.
Motifs extraits
Although the waiver was express and direct, the court held that athletes usually have no real freedom to refuse such clauses if they want to compete, so a pre-award waiver is generally not enforceable against them.
