Kernrechtsfrage
Whether the insured showed a relevant change in disability between 1997 and 2007 justifying a new pension entitlement
Extrahierter Entscheid
No materially relevant change in health or earning capacity was established for the relevant period.
Extrahierte Begründung
The Federal Supreme Court held that statistical wage data had to be used as before, that minor statistical variations do not justify revision, and that no changed circumstances supported a different income comparison. It accepted the cantonal finding that the medical condition and work capacity remained unchanged.
