Kernrechtsfrage
Whether the medical evidence established a higher incapacity than 20% and required a new independent psychiatric expertise
Extrahierter Entscheid
The bidisciplinary expertise was sufficiently reliable; no further medical inquiry was required.
Extrahierte Begründung
The experts could rely on the file, their own examination and observations. There is no general duty to obtain collateral reports from treating physicians, and the later reports did not show that decisive aspects had been overlooked.
