Key legal question
Whether the cantonal court arbitrarily fixed the husband's hypothetical monthly income at CHF 10,000.
Extracted holding
No arbitrary assessment was shown; given his banking experience, contacts, and continuing business activities, imputing CHF 10,000 was sustainable despite unemployment benefits having ended.
Extracted reasoning
Arbitrariness requires manifest insustainability. The husband had recently earned very high income, retained professional experience and contacts, and could perform commercial activities. The court could infer earning capacity from these facts.
