Questão jurídica principal
Whether the set-off defense and supporting evidence were admissible as new facts and evidence on appeal under Article 317 CPC.
Decisão extraída
The set-off defense was raised too late because the appellant could have asserted it in first instance with reasonable diligence; the appellate court therefore did not examine it.
Fundamentação extraída
A set-off plea depends on the admissibility of the facts and evidence supporting it. Here, part of the factual basis arose only after the first-instance judgment, but the loan and the possibility of making it due were already known earlier and depended solely on the appellant. Raising it only on appeal would violate the concentration principle and good faith.
