Question juridique clé
Whether the appeal challenging only the allocation of costs was admissible under federal law.
Solution extraite
The challenge was inadmissible because it concerned cantonal cost rules and did not raise a sufficiently motivated constitutional complaint.
Motifs extraits
The court held that the appellant's argument relied on Art. 89 CP but in substance targeted only costs. Since the cantonal decisions predated the CPP, cost allocation was governed by cantonal law, which cannot be reviewed on ordinary criminal appeal except for arbitrariness duly alleged and substantiated under Art. 106(2) LTF.
