Kernrechtsfrage
Whether the psychiatric diagnosis 'mixed anxiety and depressive disorder' establishes a legally relevant disability for invalidity insurance.
Extrahierter Entscheid
No. The assessed 50% work incapacity could not be relied on for disability assessment because it was predominantly explained by non-invalidating psychosocial and sociocultural factors rather than a stand-alone pathological impairment.
Extrahierte Begründung
The court held that borderline psychiatric diagnoses require careful separation of medically relevant disorder from psychosocial stressors. Where the expert assessment largely rests on external life circumstances, no invalidating health impairment exists in the legal sense.
