Questione giuridica chiave
Whether the reform appeal was admissible against the cantonal incidental decision on prescription and set-off
Decisione estratta
The decision was merely incidental; the strict conditions for an immediate reform appeal were not met because a final decision could not be brought about at once.
Motivazione estratta
Even if the appeal succeeded, the dispute would not end since the counterclaim remained open; the appellant also did not seek a final merits judgment and failed to specify the lengthy and costly evidence required.
