Questione giuridica chiave
Whether the cantonal decision was an immediately appealable interlocutory decision
Decisione estratta
It was an interlocutory decision on a preliminary point of substantive law, but the appeal was admissible because deciding the legal issue could end the case and likely avoid a lengthy, costly evidentiary phase.
Motivazione estratta
The decision did not finally resolve an independent claim, so Art. 91 LTF did not apply. Under Art. 93(1)(b) LTF, the appellant showed that a different ruling could terminate the proceedings and spare complex proof on damage.
