Questione giuridica chiave
Whether the appeal court violated due process by not ordering a further exchange of submissions after remittal.
Decisione estratta
No general right to a new exchange after remittal; the cantonal court could decide on the existing record.
Motivazione estratta
A remittal continues the case at the procedural stage reached before the first cantonal decision. If no new factual investigations are needed and the issues are already liquid, the court may decide without a further round of pleadings.
