Kernrechtsfrage
Whether the refusal to order an additional expert report violated the right to be heard or was arbitrary.
Extrahierter Entscheid
The refusal was not arbitrary because the requested evidence related to facts already sufficiently established and the prior expertise and file evidence allowed the court to reject it.
Extrahierte Begründung
The court held that anticipated assessment of evidence may justify refusing further proof unless arbitrary. The police court could rely on the existing expertise, the patrol's account, and the absence of contrary indications.
