Question juridique clé
Whether the complainant had standing to appeal against the cost allocation in a private-complaint prosecution
Solution extraite
Yes. In cantonal procedure for offences prosecuted only on complaint, the injured complainant acts as private prosecutor and may challenge a cost award before the Federal Supreme Court.
Motifs extraits
Because the public prosecutor was not entitled to conduct the prosecution, the complainant had the procedural position of an accuser privé under federal appeal rules.
