Book excerpt: "The fifth edition had to be substantially revised to reflect the impact of recent Supreme Court of Canada bellweather decisions in Grant and the companion decisions in Harrison and Suberu. These decisions require a new approach to the meaning of detention for Charter purposes and to the remedy of exclusion of evidence under section 24(2) of the Charter. Much of the voluminous prior jurisprudence on section 24(2) over the past 27 years relating to the meaning and consequences of conscripting the accused in violation of the Charter is now of little moment. New clarifications and new questions are identified."--Pub. desc.
