Kernrechtsfrage
Whether the appeal was admissible and whether the judgment had to be reviewed under the restricted appeal rules for contraventions.
Extrahierter Entscheid
The appeal was admissible but subject to the restricted scope applicable to contraventions, with review limited to legal error and manifestly incorrect fact-finding.
Extrahierte Begründung
The first-instance proceedings concerned only a contravention, so Art. 398 para. 4 CPP limited the grounds of appeal and excluded new allegations or evidence.
