The United States sought the extradition of the respondent for his role in a conspiracy to import cocaine, despite the respondent never having been in the United States during the relevant times.
The extradition judge dismissed the application for committal, finding that the United States had no jurisdiction to prosecute the offence.
The Supreme Court of Canada allowed the appeal, holding that an extradition judge's role is limited to determining whether the evidence would justify committal for trial under Canadian law if the crime had been committed in Canada.
The Court concluded that the jurisdiction of the requesting state is a matter for the executive, not the extradition judge, and that in any event, there was a real and substantial link to the United States.
