Kernrechtsfrage
Whether the complaint was admissible as a criminal appeal or had to be treated as a civil appeal.
Extrahierter Entscheid
Because the dispute concerned application of cantonal criminal procedure on referral of the civil claim, the criminal appeal was admissible.
Extrahierte Begründung
The federal characterization depends on what the cantonal appellate court decided; here the challenge targeted the procedural handling of the civil claim within the criminal case.
