Question juridique clé
Whether the complainant had standing to challenge the cantonal dismissal on the merits
Solution extraite
He lacked standing because he was neither an injured party with LAV victim status nor a private complainant; as a mere complainant he could not contest the merits of the dismissal.
Motifs extraits
The right to prosecute belonged to the State. A simple complainant may only invoke formal denial of justice, not review of the merits or fact assessment.
