 We can only decide whether the chicken coop was a ‘vehicle’ for the purpose of the Road Traffic Act by understanding the Act as pursuing something that the legislature decided to pursue, and by making an normative judgment as to whether due respect for the goal that the legislature valued through the enactment, and due respect for the requirement of certainty in criminal liability, support the conclusion that the chicken coop is to be treated as a ‘vehicle’ in the relevant sense. So we cannot apply the law without resort to evaluative and normative reasoning.
