The appellants appealed their committal for extradition to the United States on drug trafficking charges and sought judicial review of the Minister's surrender order.
They challenged the constitutionality of sections 32 and 33 of the Extradition Act, which allow the requesting state to rely on an unsworn record of the case.
The Court of Appeal dismissed the constitutional challenge, finding it was bound by its previous decision in Yang.
The Court also upheld the Minister's decision to surrender the appellants, rejecting arguments that the prosecution should occur in Canada, that the potential for life imprisonment violated fundamental justice, and that the Minister should have sought assurances for pre-trial custody credit.
