Question juridique clé
Whether the obligation for taxi drivers to display an identification plaque inside the vehicle violates freedom of personal liberty and privacy, and whether it is justified and proportionate.
Solution extraite
The rule has a sufficient legal basis and serves an public interest, but the specific plaque requirement including the driver's photo and name is disproportionate.
Motifs extraits
The interference with personal liberty is not grave, so the legal basis is reviewed for arbitrariness and found sufficient under Art. 21(2) LTaxis. Protecting taxi users and enabling identification is a legitimate public interest. However, a fixed plaque visible inside and outside the vehicle that discloses the driver's name and photograph goes beyond what is necessary; less intrusive means could achieve the same purpose.
