Questione giuridica chiave
Whether the cantonal court arbitrarily fixed the husband's monthly income at CHF 10,000.
Decisione estratta
No. Taking the average salary over several years was not arbitrary, given fluctuating income and the husband's control over his own salary.
Motivazione estratta
The court could prefer the salary average from 2005 to 2009 over lower monthly slips, since the explanations about business difficulties were contradicted by the file and average income is an accepted method for variable earnings.
