Kernrechtsfrage
Whether the insured person had proven entitlement to an invalidity pension.
Extrahierter Entscheid
No pension entitlement was established because the evidence showed no objectively ascertainable reduction in functional capacity or earning impairment.
Extrahierte Begründung
The Federal Supreme Court found no obviously incorrect factual findings. Relying on the rheumatological and psychiatric reports, it held that the appellant could perform her former job without objectively demonstrable limitations; further medical investigations were not required.
