Key legal question
Whether the finding that the appellant drove under cocaine influence on 24 November 2009 was arbitrary or unlawful.
Extracted holding
The factual finding was not manifestly inaccurate or unlawful; the evidence supported that he drove under cocaine influence.
Extracted reasoning
The cantonal court relied on clinical signs, toxicology, the timing of blood sampling, and the appellant's own admissions. The federal court held that the zero-tolerance rule for cocaine in road traffic makes the measured concentration and positive test sufficient to support the finding.
