“Extradition for the purpose of interrogation with a view to obtaining evidence for a prosecution, whether of the extradited individual or of anyone else, is not a legitimate purpose of an arrest warrant. But the judicial authority in the requested state cannot inquire into the purpose of the extradition. It is therefore necessary for there to be an unequivocal statement of that purpose in the arrest warrant itself.
“first, the phrases “is accused … of the commission of an offence” in paragraph (a), and “for the purpose of being prosecuted” in paragraph (b), are not to be treated as terms of art. Secondly, it is a question of fact whether the surrender sought is of an accused person and for the purpose of the requested person being prosecuted. Thirdly, it would be wrong to approach the construction of the phrases “accused” etc and “for the purposes of being prosecuted” solely from the perspective of English (or Scottish or Northern Irish) criminal procedure; in particular from the point of view of the formal acts of the laying of an information or the preferring of an indictment. Fourthly, it is necessary to adopt a purposive construction of the words “accused … of the commission of an offence” and “for the purpose of being prosecuted” to accommodate the differences between legal systems. Lastly, the question of whether a person is “accused” and is to be surrendered “for the purpose of being prosecuted” will require an intense focus on the facts in each case.”
“(3) […] the court will look at the wording of the warrant as a whole to decide whether the warrant indicates, unequivocally, that the purpose of the warrant is for the purpose of the requested person being prosecuted for the offences identified. (4) The court must construe the words in section 2(3)(a) and (b) in a “cosmopolitan” sense and not just in terms of the stages of English criminal procedure. […] (6) Only if the wording of the warrant is equivocal should the court consider examining extrinsic evidence to decide on the purpose of the warrant. But it should not look at extrinsic material to introduce a possible doubt as to the purpose where it is clear on the face of the warrant itself.”
“We see no reason why any formality is required in relation to the making of a decision, as a prosecutor is entitled to make a decision to try a defendant before implementing any formal steps necessary, unless the procedural law of the requesting state prevents informality. Furthermore, in our view, a decision to try is nonetheless a decision to try even if it is conditional or subject to review. ….There will, for example, be a decision to try, even if it is taken subject to the completion, after extradition, of formal stages, such as an interview and subject to those stages not causing a reversal of the decision already made even informally, to charge and try.”
“…Accordingly, while for generations making allowances for the interests of dependent children,….the need to impose appropriate sentences in accordance with established, and now statutory provisions, is unchanged. As Hughes LJ has recently explained in R v Boakye[2013] 1 Cr App R (S) 6 , para 32 : “The position of children in a defendant’s family may indeed be relevant, but it will be rare that their interests can prevail against society’s plain interest in the proper enforcement of the criminal law. The more serious the offence, generally the less likely it is that they can possibly do so.”
