Kernrechtsfrage
Whether the medical assessment of 60% work capacity was unreliable and required a court expert opinion.
Extrahierter Entscheid
The medical reports were sufficiently reliable and the lower court was entitled to rely on them.
Extrahierte Begründung
Different medical opinions and the absence of an anesthesiologist did not undermine the expertise of the rheumatology specialist; no basis for a judicial expert opinion existed.
