“32. In our judgment, evidence which was "not available at the extradition hearing" means evidence which either did not exist at the time of the extradition hearing, or which was not at the disposal of the party wishing to adduce it and which he could not with reasonable diligence have obtained. If it was at the party's disposal or could have been so obtained, it was available. It may on occasions be material to consider whether or when the party knew the case he had to meet. But a party taken by surprise is able to ask for an adjournment. In addition, the court needs to decide that, if the evidence had been adduced, the result would have been different resulting in the person's discharge. This is a strict test, consonant with the parliamentary intent and that of the Framework Decision, that extradition cases should be dealt with speedily and should not generally be held up by an attempt to introduce equivocal fresh evidence which was available to a diligent party at the extradition hearing.”
