Question juridique clé
Whether the conviction for serious traffic-rule violation under Art. 90 No. 2 SVG in connection with Art. 35 para. 2 SVG had to be set aside for lack of proof
Solution extraite
The conviction could be based on the witness testimony alone; no additional corroboration was required and there was no arbitrary assessment of evidence.
Motifs extraits
The witness statements were internally coherent, detailed, and consistent with the site plan and photos. The absence of further physical evidence did not create substantial doubt, and the lower court's view was not untenable.
