Question juridique clé
Whether the complainant had standing to challenge the no-case decision on the merits
Solution extraite
A private complainant generally lacks standing to attack a no-case decision on the merits; only formal rights violations may be raised.
Motifs extraits
Criminal prosecution belongs to the State; the injured person may invoke only violations of formal procedural rights or constitutional/CEDH hearing guarantees, not a review of the evidence or merits.
