Question juridique clé
Whether the criminal complaint was admissible despite the appellant's challenge only to the factual finding that the van was moving.
Solution extraite
The challenge did not show arbitrariness or otherwise satisfy the strict requirements for contesting the factual findings.
Motifs extraits
The appellant merely asserted, without substantiation, that the van had been stationary. He did not demonstrate, as required by Art. 106(2) BGG, that the cantonal court's assessment of the decisive facts was arbitrary.
