Questione giuridica chiave
Whether the plaintiffs had to prove the economic harm to invoke the burden of proof rule under Art. 8 CC
Decisione estratta
The complaint under Art. 8 CC was inadmissible because the cantonal court had already been convinced, on the basis of the evidence, that the business suffered a clientele loss and revenue drop.
Motivazione estratta
Art. 8 CC governs burden of proof, not evidentiary assessment. Once the court is convinced by the evidence, the burden-of-proof issue falls away; the defendant was in substance challenging fact-finding, which is not reviewable in reform proceedings.
