Questione giuridica chiave
Whether the federal appeal could be based on arbitrary fact-finding and evidence assessment regarding the husband's expense deductions and resulting income.
Decisione estratta
The complaints were either insufficiently reasoned or merely appellatory; no arbitrariness was shown.
Motivazione estratta
In a provisional family-measures case, only constitutional violations may be invoked; the appellant had to demonstrate arbitrariness specifically. He failed to show that the cantonal court's reliance on the vehicle, meal, and representation expense calculations was manifestly unsustainable.
