Kernrechtsfrage
Whether the conditions for revising the disability pension upward were met due to worsened health.
Extrahierter Entscheid
The insured person did not show a legally relevant deterioration increasing the degree of invalidity.
Extrahierte Begründung
The court found no proven durable worsening of physical capacity and accepted the psychiatric expert's assessment that overall work capacity remained 50%, so the combined effects did not change the invalidity rate.
