Kernrechtsfrage
Whether the disability pension revision justified a reduction under the mixed method after the insured's situation changed.
Extrahierter Entscheid
The change to a mixed-method assessment was a revision ground, and the overall disability degree justified no entitlement beyond a quarter pension at most.
Extrahierte Begründung
Marriage and childcare reduced the insured's gainful activity; the court accepted a 50/50 split between work and household and combined the impairments accordingly.
