Questione giuridica chiave
Whether the appellant could rely on facts and witness evidence not accepted by the cantonal court, including an alleged challenge to the underlying credit contract.
Decisione estratta
Those complaints were inadmissible or unfounded; the factual findings were binding, and the refusal to hear the witness did not violate the right to evidence.
Motivazione estratta
The appeal did not satisfy the federal requirements for attacking findings of fact. As to evidence, the cantonal court either considered the proposed testimony irrelevant or, in anticipatory assessment, incapable of changing the result.
