Key legal question
Whether the refusal to take additional evidence on appeal violated the right to be heard
Extracted holding
The complaint was inadmissible because the appellant did not show, with proper constitutional reasoning, that the cantonal court's refusal under cantonal procedural rules was arbitrary or contrary to the minimum constitutional guarantees.
Extracted reasoning
The court held that the appellant failed to demonstrate that the requested cassette and witness hearing met the conditions for additional evidence on appeal, and he did not substantiate arbitrariness in the anticipatory assessment of relevance.
