(2) In deciding whether the extradition would be disproportionate, the judge must take into account the specified matters relating to proportionality (so far as the judge thinks it appropriate to do so); but the judge must not take any other matters into account. (3) These are the specified matters relating to proportionality – (a) the seriousness of the conduct alleged to constitute the extradition offence; (b) the likely penalty that would be imposed if D was found guilty of the extradition offence; (c) the possibility of the relevant foreign authorities taking measures that would be less coercive than the extradition of D.
