Duke v R

Duke v R, or Duke v. Regina, is a commonly abbreviated citation for a Canadian legal case heard by the Supreme Court of Canada. The full case name is His Majesty the King v. Duke. It is a significant decision dealing with entrapment and its application in Canadian criminal law. The case is often cited for its articulation of the legal principles surrounding entrapment, particularly the distinction between permissible and impermissible police conduct in obtaining evidence or securing convictions. Specifically, the court clarified the nature of entrapment as an abuse of process and provided guidance on when a trial judge should exclude evidence or stay proceedings because of it. The decision in Duke v R continues to be influential in Canadian courts when assessing claims of entrapment.
