Kernrechtsfrage
Whether the insured person's disability pension should be increased on revision due to a material deterioration in health before 24 June 2005.
Extrahierter Entscheid
No material deterioration was shown; the existing quarter pension remained unchanged.
Extrahierte Begründung
The new medical reports showed no new somatic diagnoses and only mild depressive symptoms, which did not amount to a disabling psychiatric disorder. The cantonal court's factual findings were not manifestly incorrect, and no further evidence was required.
