Question juridique clé
Whether the cantonal appeal court violated the law by reassessing the facts and not limiting itself to the first judge's findings
Solution extraite
No. The appeal court could freely review the legal scope of Art. 32 LCR and consider omitted factual elements relevant to speed adaptation and lane position.
Motifs extraits
In a contravention-only case, factual review on appeal is limited to arbitrariness, but legal qualification remains free; the cantonal court did not ignore the first-instance findings, it found them incomplete for applying Art. 32 and 34 LCR.
