Kernrechtsfrage
Whether the medical file was sufficient to deny a pension without further expert assessment.
Extrahierter Entscheid
The file was not sufficiently clarified; additional medical investigations, including psychiatric assessment, were required.
Extrahierte Begründung
The court held that treating physicians' reports and the rehabilitation clinic records did not meet the requirements of a probative administrative expert opinion. There were significant doubts about completeness and correctness, and chronic pain warranted psychiatric assessment.
