Questione giuridica chiave
Whether the criminal complaint was admissible despite the complainant's lack of standing as a private prosecutor or victim
Decisione estratta
The complainant lacked standing under Art. 81 BGG; as a merely injured party not directly affected in bodily, psychological, or sexual integrity, he could not challenge the merits.
Motivazione estratta
The prosecution had participated in the cantonal proceedings, the complainant was not a private prosecutor under Art. 81(1)(b)(4) BGG, not a victim under Art. 81(1)(b)(5) BGG, and did not invoke the criminal complaint right itself under Art. 81(1)(b)(6) BGG.
