Question juridique clé
Whether a private complainant may appeal an acquittal without maintaining civil claims in the criminal file.
Solution extraite
Yes. The complainant has standing under Art. 382 CPP even if no civil claims were pursued or were later withdrawn, so long as it participated as a party complainant.
Motifs extraits
The CPP allows the injured person to join solely to support the criminal prosecution. Standing for appeal does not depend on actually asserting civil claims; the role of complainant and the protected interest in the conviction issue suffice. The federal-court standing rule in Art. 81 LTF is not controlling for Art. 382 CPP.
