Kernrechtsfrage
Whether the speed measurement was unlawfully obtained and could not support the administrative measure.
Extrahierter Entscheid
No. The speeding evidence was not unlawfully obtained, and the driver's fair-trial complaint failed.
Extrahierte Begründung
The driver did not claim the signs were hidden; valid speed-limit signs had been lawfully installed and published. The cited ECHR case involved police incitement and was not comparable.
