Kernrechtsfrage
Whether a relevant deterioration in health since January 2006 justified an increased disability pension
Extrahierter Entscheid
No relevant deterioration was proven; the existing quarter pension remained unchanged.
Extrahierte Begründung
The later medical reports did not show a meaningful worsening compared with the 2006 assessment. The cantonal findings were not manifestly incorrect, and further evidence could be omitted in anticipatory assessment.
