Question juridique clé
Whether Art. 8 ZGB required the appellate court to admit or order expert evidence on the value of the paintings
Solution extraite
Art. 8 ZGB guarantees only the taking of properly and procedurally offered evidence; the plaintiff had not validly offered further evidence, and ordering an expert report ex officio was a matter of cantonal procedure.
Motifs extraits
The plaintiff had named only two gallery witnesses and expressly did not request an expertise in the evidentiary statement. Whether the court must order evidence ex officio depends on cantonal procedural law and was not reviewable on appeal.
