Kernrechtsfrage
Whether the cantonal court could deny a disability pension without further medical investigation.
Extrahierter Entscheid
The decision could not stand on the hand-related medical record alone; further medical clarification was required before reassessing pension entitlement.
Extrahierte Begründung
The RAD assessment was based only on records and was contradicted by several examining specialists who attested full incapacity. This created at least slight doubts about its reliability, triggering the need for external or judicial expert evidence.
