Whether the appellate court violated Art. 8 ZGB by refusing a witness and by accepting proof of regular maintenance payments.
Decisione estratta
No. Art. 8 ZGB does not regulate the choice or assessment of evidence, and anticipatory evaluation of evidence is permissible.
Motivazione estratta
The court may refuse evidence it deems incapable of changing the result; factual findings and evidentiary assessment are not reviewable on appeal.
