Questão jurídica principal
Whether a federal civil appeal is admissible against an incidental cantonal decision that remands the divorce case and denies appellate costs and expenses.
Decisão extraída
The appeal is inadmissible because the challenged costs ruling, attached to an incidental decision, does not cause irreparable legal harm.
Fundamentação extraída
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.
