Questione giuridica chiave
Whether the appeal court violated Art. 8 CC by allegedly requiring the claimant to prove the defendant's role as sub-mandatary and causal contribution.
Decisione estratta
No. The cantonal court made positive factual findings that the defendant acted, at most, as an adviser and not as a decisive participant; Art. 8 CC does not govern the judge's evaluation of evidence.
Motivazione estratta
Art. 8 CC concerns the burden of proof, not the assessment of evidence. Because the cantonal court based its ruling on an evidentiary appraisal of documents and testimony, the provision was not infringed.
