Kernrechtsfrage
Whether the posttraumatic stress disorder and related incapacity were naturally causally linked to the assault.
Extrahierter Entscheid
Yes. The medical file, especially the psychiatric expert report, established natural causation; lay statements could not displace it.
Extrahierte Begründung
No contrary medical opinion existed. Non-medical observations by the insurer's investigator and employer could not undermine the expert diagnosis.
