Kernrechtsfrage
Whether the cantonal criminal appeals chamber could decide the contravention appeal by a single judge.
Extrahierter Entscheid
Yes. Because the appeal concerned exclusively contraventions, the chamber's procedural direction could rule alone.
Extrahierte Begründung
Art. 395 let. a CPP allows a single judge to decide when the appeal concerns only contraventions, even if the chamber is normally collegial.
