Kernrechtsfrage
Whether the revocation of the quarter invalidity pension was justified under revision rules because economic circumstances had changed.
Extrahierter Entscheid
Yes. A change in the insured person's economic situation, due to adapted employment and higher actual earning capacity, justified revision even without a change in health.
Extrahierte Begründung
For insured persons in gainful employment, invalidity is determined by comparing hypothetical income without disability and income with disability. The adapted job was stable and reflected actual work performed, so actual earnings could be used.
