Questão jurídica principal
Whether the defendant's verbal and passive refusal constituted obstruction under Art. 91a SVG in conjunction with Art. 55 SVG.
Decisão extraída
Yes. A sustained verbal refusal, even without physical resistance, can qualify as obstruction if it clearly prevents or hinders the examination and shows a sufficient intent to evade it.
Fundamentação extraída
Art. 91a SVG does not require active physical resistance. Passive resistance may suffice if it has a certain intensity and makes the measure difficult, delayed, or obstructed. The defendant repeatedly and unmistakably refused both breath and blood testing despite police warnings, so his behavior amounted to resistance.
