Questione giuridica chiave
Whether the cantonal court wrongly refused new documents on appeal under Art. 317 CPC.
Decisione estratta
The complaint was inadmissible because the appellant did not challenge the cantonal court's alternative holding that the new documents would not change the outcome anyway.
Motivazione estratta
The lower court relied on two independent reasons; the appellant attacked only one. Without a challenge to the proof assessment on the alternative ground, the issue could not affect the judgment.
