Questão jurídica principal
Whether the cantonal court violated the right to be heard by refusing to hear the treating psychiatrist and the expert.
Decisão extraída
No violation was shown; the court could validly refuse the hearings after an anticipatory assessment of the evidence.
Fundamentação extraída
The written evidence was sufficient, and oral testimony was unlikely to change the court's conviction; the complaint largely concerned evidentiary assessment rather than hearing rights.
