The appellant sought to persuade the House that in extradition proceedings the courts enjoyed a similar jurisdiction to that exercised in Bennett.
Held: The appeal failed. The High Court has no inherent power to intervene in extradition proceedings outside the terms of the Act. ‘Accordingly, the position now is that in extradition proceedings under the Act of 1989 the High Court has power to intervene only in the circumstances predicated by the Act and has no inherent Common Law supervisory power as contended for by the applicant. The principal safeguard for the subject of extradition proceedings therefore remains in the general discretion conferred upon the Secretary of State by Parliament in Section 12. ‘
Lord Jauncey of Tullichettle said: ‘My Lords, I summarise my conclusions on this branch of the case thus. Atkinson v United States of America Government  AC 197 decided that Parliament had excluded the jurisdiction of the courts to refuse to surrender a person under the 1870 Act when to do so would be unjust or oppressive. R v Governor of Pentonville Prison, Ex p Narang  AC 247 emphasised that the statutory powers conferred upon the courts by the 1881 Act in relation to the Empire had been considerably restricted by section 8(3) of the 1967 Act. R v Governor of Pentonville Prison, Ex p Sinclair  2 AC 64 pointed out that the re-enactment of section 8(3) in section 11(3) of the Act of 1989 demonstrated that in relation to foreign countries no discretion to refuse the return of a foreign fugitive had previously existed. The dicta in Government of Australia v Harrod  1 WLR 745 and In re Osman, 28 February 1992 were obiter. R v Horseferry Road Magistrates’ Court, Ex p Bennett  1 AC 42 related to the very different situation of the power to stay an English prosecution. Accordingly, the position now is that in extradition proceedings under the 1989 Act the High Court has power to intervene only in the circumstances predicated by the Act and has no inherent common law supervisory power as contended for by the applicant. The principal safeguard for the subject of extradition proceedings therefore remains in the general discretion conferred upon the Secretary of State by Parliament in section 12. It follows that the Divisional Court were correct in concluding that the decisions in Atkinson and Sinclair had not been affected by Bennett and should be followed.’
