Question juridique clé
Whether the factual findings on speeding were arbitrary and violated in dubio pro reo
Solution extraite
No. The canton court could rely on the consistent testimony of the two sworn officers and on their speedometer-based observations, with a safety margin deducted.
Motifs extraits
The federal court held that such testimony can suffice for proving speeding; the appellant's criticisms were mainly appellatory and did not show manifest insoutenable assessment of evidence.
