Kernrechtsfrage
Whether the cantonal court arbitrarily assessed the father as able to earn an imputed net income of CHF 3,000 per month from 1 April 2004.
Extrahierter Entscheid
No. The court could rely on medical and labor-market indications to conclude that the father was basically employable and could earn the imputed income.
Extrahierte Begründung
The review was limited to arbitrariness. The cantonal court had not drawn untenable conclusions from the medical evidence and could use the Swiss wage statistics instead of the collective labor agreement minimum wage to estimate realistic earnings.
