Questão jurídica principal
Whether the cantonal appellate court had to hold an oral hearing rather than decide in writing.
Decisão extraída
The written procedure was permissible because the defendant did not timely object and the court could rely on the parties' implied consent.
Fundamentação extraída
Article 406 StPO allows written appellate proceedings in defined cases. The defendant raised no timely objection after the order for written proceedings, and the case did not require a personal impression for prognosis.
