Kernrechtsfrage
Whether a revision-relevant change in the insured person's actual circumstances occurred during the relevant period, justifying a higher disability pension.
Extrahierter Entscheid
No relevant change in circumstances was shown; the previously assessed invalidity degree remained decisive.
Extrahierte Begründung
The court upheld the mixed-method assessment and found no legally relevant error in the calculation of invalidity, in the assumed work capacity, or in the household limitation. The challenged findings on hypothetical income, residual earning capacity and household impairment were not shown to be manifestly incorrect.
