Judicial Jurisdiction and Abuse of Process

British cases used to be widely relied upon to show that courts were entitled to hear criminal proceedings against defendants brought before them without having to enquire into the process by which custody over them had been obtained: and specifically, that there was no bar to proceeding where the allegation was made that custody had been obtained in breach of international law.1 The consistency of the doctrine was breached by Mackeson2 when the English court refused to hear the case against a defendant who, it accepted, had been brought to England by a collusive process between the English and Zimbabwean authorities, which arguably breached both national laws, even if it did not involve a breach of international law. While the previous orthodoxy soon reasserted itself in Driver,3 the edifice of authority was substantially undermined in Bennett4 when the House of Lords acceded to the claim of the applicant that proceedings against him would be an abuse of process, given the circumstances in which his presence in the United Kingdom had been achieved. Outside the United Kingdom, the practice in other States continued in different directions, sometimes confirming the old position of male captus, bene detentus,5 sometimes the reverse.6
