Question juridique clé
Whether the complainant had standing to challenge the cantonal decision on the merits
Solution extraite
He lacked standing because he was only a complainant and not a victim or private accuser with a legally protected interest.
Motifs extraits
The prosecution belongs to the State; a mere injured person or complainant cannot attack a discontinuance on the merits, but may only raise formal denial of justice complaints, which were not alleged.
