Questão jurídica principal
Whether the finding that the appellant drove under cocaine influence on 24 November 2009 was arbitrary or unlawful.
Decisão extraída
The factual finding was not manifestly inaccurate or unlawful; the evidence supported that he drove under cocaine influence.
Fundamentação extraída
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.
