Kernrechtsfrage
Whether the appellant's right to be heard was violated because the expert report was insufficient and no written detailed report was obtained.
Extrahierter Entscheid
No violation occurred; the oral explanation and the driving protocol were sufficient for the appellant to challenge the result.
Extrahierte Begründung
Neither statute nor the relevant asa guidelines required a written expert report. The expert communicated the negative result and the recorded defects, and the later telephone inquiry concerned the claimed illness, not the driving errors.
