Key legal question
Whether the cantonal court violated the investigation principle by relying on incomplete medical evidence and refusing further expert evidence
Extracted holding
The factual record on somatic and psychological health and work capacity was incomplete; further multidisciplinary medical assessment was required.
Extracted reasoning
The RAD report and the other medical records were not sufficiently comprehensive, consistent, or well-founded; contradictions were not addressed, no psychiatric assessment was made, and vocational findings pointed to possible incapacity.
