Question juridique clé
Whether the criminal appeal was sufficiently reasoned under Art. 42 LTF to be examined on the merits.
Solution extraite
No. The appellant did not explain why the cantonal court's reasoning allegedly violated federal law.
Motifs extraits
The appeal must state why the challenged decision is unlawful. Mere references to traffic-law provisions and technical vehicle certificates did not address the decisive reasoning of the lower court.
