Question juridique clé
Whether the state complaint could challenge alleged violations of federal law and contractual interpretation under Art. 736 ZGB and Art. 18 OR.
Solution extraite
Those complaints had to be brought by appeal, not by state complaint, so the Federal Court would not examine them.
Motifs extraits
State complaint is limited to constitutional rights; alleged federal-law errors and interpretation under the reliance principle are not cognizable in this procedure.
