Kernrechtsfrage
Whether the federal appeal could be entered into despite the cantonal court's main reasoning that causation was not proved to the requisite standard.
Extrahierter Entscheid
The challenge was not decisive because the cantonal court's finding that the alleged damage scenario was not established with predominant probability was not shown to be arbitrary.
Extrahierte Begründung
The complaint targeted the evidentiary standard, but the decisive factual finding was the absence of predominant probability. Since that finding was not specifically and sufficiently attacked, the issue was immaterial.
