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