Kernrechtsfrage
Whether the refusal to revise the quarter disability pension and grant a full disability pension should be overturned
Extrahierter Entscheid
No. The record did not show, with the requisite probability, a material change in health during the relevant revision period.
Extrahierte Begründung
The Federal Court agreed with the cantonal court's careful assessment of the medical reports and found no violation of federal law. The appellant's arguments were largely inadmissible criticism of evidence appraisal.
