Kernrechtsfrage
Whether the cantonal decision refusing modification of support measures was arbitrary under Art. 9 BV
Extrahierter Entscheid
The complaint did not show that the cantonal court's assessment of income and earning capacity was manifestly untenable.
Extrahierte Begründung
The husband argued only in an appellatory manner; the cantonal court had addressed the alleged reduction in workload, found the employer's explanations not credible, and reasonably relied on his prior earning capacity and managerial role.
