Challenging moral involuntariness as a principle of fundamental justice

In R. v. Ruzic, the Supreme Court of Canada made the criminal law concept of moral involuntariness a principle of fundamental justice warranting Charter protection. This comment challenges that decision by contending that, in the overall scheme of determining criminal responsibility, moral involuntariness has only a subsidiary role to play. Futhermore, the concept lacks sufficient constraint and is too imprecise to qualify as a principle of fundamental justice.
