Kernrechtsfrage
Whether X. had a legally protected interest to challenge the dismissal of the proceedings against him under Art. 54 StGB
Extrahierter Entscheid
No. The dismissal under Art. 54 StGB did not contain a finding of criminal guilt and therefore did not create an appealable prejudice for X.
Extrahierte Begründung
Art. 54 StGB may be applied already by the investigating authority before criminal guilt is established. The dismissal expressly left criminal responsibility open; it therefore did not determine that X. had committed an offence and did not prejudice related proceedings or civil/victim claims.
