Kernrechtsfrage
Whether the contractual reference to FIFA rules constituted a valid choice of law under Art. 116 IPRG
Extrahierter Entscheid
The reference to FIFA rules was not a choice of law; it was only a substantive contractual incorporation. The chosen law remained Swiss law, including mandatory rules.
Extrahierte Begründung
Private association rules are not 'law' within Art. 116 IPRG. They can only apply as contractual terms and remain subordinate to mandatory Swiss law. The lower court therefore wrongly treated the FIFA rules as a lex specialis choice of law.
