Questione giuridica chiave
Whether the cantonal court was incompetent to address the amount of the father’s maintenance contribution after the AVS child pension started
Decisione estratta
The cantonal court did not decide that issue in its operative part; its remarks on maintenance reduction under federal law were obiter dicta.
Motivazione estratta
The dispute before it concerned only entitlement to cantonal advance payments, which may require a preliminary reference to the divorce judgment but not a binding ruling on the civil maintenance amount.
