Question juridique clé
Whether the appellant's verbal refusal and resistant conduct amounted to evasion of measures to determine driving fitness under Art. 91a SVG.
Solution extraite
Yes. Persistent verbal refusal, combined with agitated and aggressive conduct, can constitute punishable evasion if it hinders the execution of the ordered test.
Motifs extraits
The offense requires active disruptive conduct or passive resistance of some intensity; force is not necessary. The appellant's half-hour refusal, agitation, and the need to handcuff him showed sufficient intensity to obstruct the test.
