Key legal question
Whether changed circumstances justified modifying the spousal maintenance order under Art. 179 CC.
Extracted holding
The husband failed to show a sufficient durable and significant change warranting reduction of the maintenance contribution.
Extracted reasoning
The cantonal court could find that the relevant circumstances had essentially remained the same after updating the parties' financial situation; the husband's alleged child-related expenses did not justify a reduction, and the wife's income situation did not change the result.
