Key legal question
Whether the cantonal court violated the accused's right to be heard, the accusation principle, good faith, or the presumption of innocence by relying on an allegedly new factual version.
Extracted holding
No. The appellate court did not introduce a new factual basis; it left open the exact conduct of the other driver because it was irrelevant to the legal assessment.
Extracted reasoning
The challenge was merely appellatory. The finding that the defendant's version would still amount to a traffic-rule violation was sufficient, so no constitutional or procedural violation occurred.
