Questione giuridica chiave
Whether the maintenance contributions had to be recalculated and reduced from the filing date of the husband’s modification request.
Decisione estratta
No; the constitutional complaint did not show a constitutionally cognizable error in the maintenance calculation.
Motivazione estratta
The cantonal courts could rely on average income figures, including business profit and dividend potential, and the complaint did not substantiate arbitrariness or a hearing violation.
