Kernrechtsfrage
Whether the cantonal court arbitrarily assessed the evidence by relying on the judicial expert and rejecting private expert opinions
Extrahierter Entscheid
No arbitrary assessment was shown; the judicial expert was usable and the cantonal court could prefer it over private reports.
Extrahierte Begründung
Private expert opinions have no special evidentiary force, while judicial expertise is decisive unless it contains evident defects. The expert's conclusions were not contradictory or incomprehensible, so the cantonal court could follow them.
