"A person’s extradition to a category 1 territory is barred by reason of the passage of time if (and only if) it appears that it would be unjust or oppressive to extradite him by reason of the passage of time since he is alleged to have committed the extradition offence or since he is alleged to have become unlawfully at large (as the case may be)."
"I reject that and find on seeing/hearing him it is plain that he fled Poland to avoid criminal proceedings and has manipulated the system here in the UK, claiming victimisation if returned. He had a lawyer at public expense in Poland and no reason to fear he would be unable to defend himself if returned."
"'Unjust' I regard as directed primarily to the risk of prejudice to the accused in the conduct of the trial itself, 'oppressive' as directed to hardship to the accused resulting from changes in his circumstances that have occurred during the period to be taken into consideration; but there is room for overlapping, and between them they would cover all cases where to return him would not be fair. Delay in the commencement or conduct of extradition proceedings which is brought about by the accused himself by fleeing the country, concealing his whereabouts or evading arrest cannot, in my view, be relied upon as a ground for holding it to be either unjust or oppressive to return him. Any difficulties that he may encounter in the conduct of his defence in consequence of the delay due to such causes are of his own choice and making. Save in the most exceptional circumstances it would be neither unjust nor oppressive that he should be required to accept them."
"But I have no doubt that it is not the law that if there is proved to be culpable delay in finding the man it is therefore necessarily unjust or oppressive to extradite him, any more than it is necessarily unjust or oppressive to try a domestic English defendant because the police have been (culpably) less than assiduous in catching him. Although culpable delay may be relevant, the principal focus, when it comes to considering the passage of time, is not on a judgment on the performance of the requesting state's investigation but on the effect that time passing has had."
