"... the court shall order the applicant's discharge if it appears to the court in relation to the offence, or each of the offences, in respect of which the applicant's return is sought, that - ... (b) by reason of the passage of time since he is alleged to have committed it or to have become unlawfully at large, as the case may be; or (c) because the accusation against him is not made in good faith in the interests of justice, It would, having regard to all the circumstances, be unjust or oppressive to return him."
"'Unjust' is directed primarily to the risk of prejudice to the accused in the conduct of the trial itself, 'oppressive' [is directed primarily] to hardship to the accused resulting from changes in his circumstances that have occurred during the period taken into consideration."
"... if the court concluded that the domestic court of the requesting state would be bound to hold that a fair trial of the accused was impossible then it would be unjust to return him."
