Questione giuridica chiave
Whether a federal civil appeal is admissible against an incidental cantonal decision that remands the divorce case and denies appellate costs and expenses.
Decisione estratta
The appeal is inadmissible because the challenged costs ruling, attached to an incidental decision, does not cause irreparable legal harm.
Motivazione estratta
A costs order tied to an incidental decision can be challenged later together with the final decision under Art. 93(3) LTF. Exposure to paying money does not normally create irreparable harm, and the appellant did not show any exceptional circumstance.
