Questão jurídica principal
Whether the father could challenge the maintenance assessment by arguing his income was only hypothetical and lower than assumed.
Decisão extraída
The complaint contained only unsubstantial, appellate criticism and did not show arbitrariness in the finding that he could earn CHF 6,000 net monthly at full capacity.
Fundamentação extraída
In child maintenance matters under Art. 98 BGG, only constitutional violations may be raised. The appellant did not demonstrate any qualified, obvious defect in the cantonal court's assessment of earning capacity and income calculation.
