Questão jurídica principal
Whether the cantonal court violated the appellant's right to be heard or acted arbitrarily when assessing his income for maintenance purposes.
Decisão extraída
No violation was shown: the complaint did not identify omitted evidence, and the income assessment was not manifestly untenable.
Fundamentação extraída
The appellant failed to show a timely, specific evidentiary request that was ignored. The court could rely on the latest tax assessment and its estimate of yearly income was not arbitrary.
