Question juridique clé
Whether costs could be imposed after discontinuation despite no conviction.
Solution extraite
No. A cost order after discontinuation cannot rely on criminal fault; it is allowed only if the accused clearly violated a civil-law duty and thereby caused or complicated the proceedings.
Motifs extraits
The cantonal court relied on traffic rules amounting to criminal norms, which cannot support a cost order when the case ended without conviction. The appellant's conduct was at most minor and had led to discontinuation, not to culpable initiation of proceedings.
