Key legal question
Whether the cantonal court arbitrarily refused to find a relevant and lasting change of circumstances justifying modification of maintenance measures.
Extracted holding
No. The prior income-imputation remained justified because no essential and durable change in circumstances was shown.
Extracted reasoning
The husband had not proved that his earning capacity had materially and durably changed since the earlier measures. The lower court could keep imputing a hypothetical income of CHF 6,150 per month based on his qualifications, experience, and unclear financial situation.
