K charged with impaired driving. Was at dentist gave him drug/didn’t know would affect him
Whether the accused’s lack of knowledge of the effects to the drug would affect his liability for impaired driving – does it mean lack of knowledge was voluntary?
Criminal liability requires voluntary act – knowledge important for voluntariness of actus reus
**Accused must have a willing mind and at liberty to make a choice – if not, then not voluntary
There can be no actus reus unless it is the result of a willing mind at liberty to make a definite choice or decision. There must be willpower to do an act
Appellant became impaired through no act of his own – not guilty
