Criminal Law Defences, 5th edition, is a quick, clear and authoritative exposition of the criminal defences available in Canadian law, including lesser known defences not dealt with by standard texts. The fifth edition includes numerous substantive changes to the law since the last edition. It provides new and revised commentary on a broad range of issues relating to the law of defences based on recent case authority and statutory amendments. Notably, the new addition offers revised commentary and updated case information on the justifications of defence of the person and property, the excuses of accident, intoxication and provocation, and the meaning of consent.
