Kernrechtsfrage
Whether refusing the requested evidence (METAS expert opinion, records, photos, witness hearings) violated the right to be heard or was arbitrary anticipatory assessment.
Extrahierter Entscheid
The refusal was permissible because the existing evidence supported the radar measurement and the requested evidence could not change the court's conviction.
Extrahierte Begründung
The radar installation was approved, tested and documented; no concrete indications of malfunction, interference, double reflection or knick-beam error existed; the sons' testimony would not meaningfully undermine the measurement.
