Kernrechtsfrage
Whether the cantonal court arbitrarily calculated the husband's disposable income by counting the child support twice
Extrahierter Entscheid
Yes. The previous judgment included the former 760 CHF child-support amount in the husband's charges and then deducted the newly fixed 40 CHF again.
Extrahierte Begründung
This was an untenable calculation under Art. 9 Cst.; correcting it increased the spouses' combined disposable income and the wife's maintenance share.
