Questão jurídica principal
Whether refusing to hear the defendant's brother and wife violated the right to be heard, arbitrariness, or the presumption of innocence.
Decisão extraída
The refusal was lawful because the proposed witnesses were closely connected to the defendant and could not materially alter the evidentiary assessment; no constitutional violation occurred.
Fundamentação extraída
The appellate court accepted anticipatory assessment of evidence: the cantonal court could conclude without arbitrariness that the additional hearings would not change its view.
