Kernrechtsfrage
Whether the disability pension could be increased because of a material change in health and earning capacity
Extrahierter Entscheid
No material deterioration was shown; the insured remained capable of light to medium adapted work at 50%, so only a half pension was justified.
Extrahierte Begründung
The Federal Supreme Court upheld the lower court's reliance on a multidisciplinary medical assessment and found no obvious error in its factual findings or legal assessment under the limited review of Art. 105 BGG.
