Question juridique clé
Whether the speed measurement was admissible despite being conducted contrary to VZV rules by a private person
Solution extraite
The measurement could not be relied upon because the mandatory police-control rules were violated and the defect was not outweighed by the interests in proof.
Motifs extraits
The VZV allocates speed controls to competent police authorities and is not merely organizational. Since no explicit exclusion rule existed, admissibility turned on the protective purpose of the rules and balancing interests. Here the formal violation impaired the defendant's right to a lawful and fair evidence-gathering process, and the case was not one of serious crime.
