Kernrechtsfrage
Whether the complainant had standing to challenge the dismissal of the criminal investigation.
Extrahierter Entscheid
No. He was neither a private prosecutor nor a victim within the meaning of the Criminal Victims Act, and as a merely injured party he had no appeal standing.
Extrahierte Begründung
The public prosecutor was a party to the cantonal proceedings, excluding private-prosecutor status. The alleged fraud did not directly affect the complainant's physical, psychological, or sexual integrity, so victim status was absent. No independent claim of procedural-right violations was raised.
