The House considered the role of the metropolitan magistrate under section 9 and 10 of the 1870 Act in the context of an application for extradition under the treaty between Denmark and the United Kingdom. At section 9 hearings it had been the invariable practice, ‘so far as living memory stretches’, for the magistrate to receive evidence of the law of the requesting state designed to show that the offence of which the fugitive was accused in that state was ‘substantially similar’ or ‘similar in concept’ to the relevant extradition offence, as construed according to English law.
Held: In an application for extradition, it was for the Secretary of State to specify the crime or crimes for which the fugitive criminal’s extradition was being requested, and the District Judge had no jurisdiction to inquire into or receive evidence of the criminal law of the foreign state. It did not however follow that the District Judge was confined by the way in which the case was described in the order to proceed as to the category into which the appellant’s case fell.
The list of exradition crimes provided in the schedule, described the 19 ‘extradition crimes’ in general terms and popular language.
Lord Diplock said: ‘[T]he magistrate is not concerned with what provision of foreign criminal law (if any) is stated in the warrant to be the offence which the person was suspected of having committed and in respect of which his arrest was ordered in the foreign state.’
