Questione giuridica chiave
Whether the cantonal decision refusing to find changed circumstances under Art. 179 ZGB was arbitrary
Decisione estratta
No arbitrariness was shown; the appellate court could weigh the wife's higher income against the husband's reduced actual payments and conclude that no relevant change justified modifying maintenance.
Motivazione estratta
The husband relied mainly on the wife's income increase. The court held that the lower court could consider his actual, lower payments and his payment behavior, and could also treat the wife's full-time work and childcare burden as making her income only partly attributable for maintenance calculation.
