Questione giuridica chiave
Whether the complaint alleging that a witness should have been heard through an interpreter was admissible
Decisione estratta
The challenge was inadmissible because the asserted lack of German proficiency was not established in the record and the objection was not raised in time before the cantonal courts.
Motivazione estratta
The appellant relied on factual assertions not found in the appealed judgment and did not properly invoke a reviewable factual error. Moreover, she did not request an interpreter at the taking of evidence or immediately complain, so the objection came too late and was barred by good faith and the prohibition of abuse of rights.
