The appellants, Canadian citizens, faced extradition to the United States for telemarketing fraud.
During the extradition process, an American judge and prosecutor made threatening statements indicating that uncooperative fugitives would receive maximum sentences and face sexual violence in prison.
The extradition judge stayed the proceedings, finding these threats violated the principles of fundamental justice.
The Court of Appeal set aside the stay, ruling the judge should have deferred to the Minister of Justice's surrender decision.
The Supreme Court of Canada allowed the appeal and reinstated the stay, holding that the extradition judge has jurisdiction under the Charter and common law to remedy abuses of process that directly taint the committal hearing, without waiting for the executive phase.
