Kernrechtsfrage
Whether the insured person was entitled to disability insurance benefits.
Extrahierter Entscheid
No entitlement was established because the courts could rely on the ZMB expert report showing work capacity despite reduced performance.
Extrahierte Begründung
The medical findings were not shown to be arbitrary or contradictory; the complainant's submissions and later psychiatric reports did not cast concrete doubt on the report's reliability.
