“27. I am in fact satisfied that it is neither principled nor practical to apply the principle in Henderson v Henderson in a straightforward manner to extradition warrant decisions. Extradition involves the issuing of a warrant by a foreign authority which engages the UK's international obligations as well as its domestic legislation. Statutory bars have been enacted which reflect those arrangements, whether Treaty or Framework Decision. There is no scope for more than a residual jurisdiction to preclude the extradition of someone who falls outside the scope of the statutory bars. That is the residual jurisdiction envisaged in the line of cases leading to Belbin, where the contention is that the prosecutor or judicial authority has acted in bad faith, deliberately manipulating proceedings, undermining the statutory regime to the unfair prejudice of the defendant. Such a jurisdiction is consistent with those international obligations only because it is obvious that no prosecutor or issuing authority should behave in the manner described in Belbin as an abuse of the court's process; it is necessarily implicit in the arrangements, and accepted by all participants, that they would not be allowed to do so.”
