Question juridique clé
Whether the criminal complaint could be heard despite the appellant's lack of substantiated civil-claim standing.
Solution extraite
The appellant failed to show, or make plausible, how the challenged decision could affect any civil claim arising from the alleged defamation; the appeal was therefore not admissible.
Motifs extraits
A private complainant may appeal in criminal matters only if the decision can affect civil claims. Where this is not obvious, the appellant must explain the possible impact. He did not do so here.
