Question juridique clé
Whether the plaintiff could invoke Art. 8 ZGB to obtain further evidence on the alleged authorization for the assignment.
Solution extraite
No. The lower court had evaluated the evidence and reached a factual conclusion; Art. 8 ZGB does not control evidence appraisal or oblige the court to take specific evidence.
Motifs extraits
Art. 8 ZGB governs burden of proof and access to proof, but not the weighing of evidence. Since the lower court did not leave the matter in evidentiary doubt, the burden-of-proof rule was irrelevant.
