Question juridique clé
Whether the public-law appeal could challenge the finding of facts and evidence assessment as arbitrary and invoke the presumption of innocence
Solution extraite
The appeal was admissible only insofar as it alleged arbitrary evidence assessment and a violation of the presumption of innocence; other complaints were inadmissible.
Motifs extraits
A nullity appeal did not lie for arbitrary fact-finding or direct constitutional/convention claims, but public-law review was open for those grievances. The challenge to the qualification of serious fault under road traffic law was not cognizable in this procedure.
