Question juridique clé
Whether the traffic measures were lawful under Art. 3(4) SVG and general administrative law principles.
Solution extraite
Traffic measures are lawful only if they serve the statutory purposes and satisfy proportionality; private resident interests affected by diversions and emissions must be weighed against the public interest.
Motifs extraits
The court held that measures under Art. 3(4) SVG must pursue traffic safety, facilitation, regulation, road protection, or other local reasons, and must also comply with proportionality. If protected private interests are impaired, the measure is permissible only when the public interest clearly prevails after balancing.
