Questione giuridica chiave
Whether the cantonal remand judgment was a final decision or an appealable incidental decision under the Federal Supreme Court Act
Decisione estratta
The remand order left the lower court with discretion to reassess the maintenance claim under Art. 163 CC and was therefore an incidental decision, not a final one.
Motivazione estratta
A remand is only treated as final when the lower authority has no latitude left. Here, the first judge still had to examine whether the maintenance should be modified and, if so, determine the amount.
