“the single question therefore for the appellate court is whether or not the district judge made the wrong decision. It is only if the court concludes that the decision was wrong, applying what Lord Neuberger PSC said, as set out above, that the appeal can be allowed. Findings of fact, especially if evidence has been heard, must ordinarily be respected. In answering the question whether the district judge in the light of those findings of fact, was wrong to decide that the extradition was or was not proportionate, the focus must be on the outcome, that is on the decision itself. Although the district judge’s reasons for the proportionality decision must be considered with care, errors and omissions do not of themselves necessarily show that the decision on proportionality itself was wrong.”
“25…. Extradition appeals are not re-hearings of evidence or mere repeats of submissions as to how factors should be weighed; courts normally have to respect the findings of fact made by the district judge, especially if he has heard oral evidence. The true focus is not on establishing a judicial review type of error, as a key to opening up a decision so that the appellate court can undertake the whole evaluation afresh. This can lead to a misplaced focus on omissions from judgments or on points not expressly dealt with in order to invite the court to start afresh, an approach which risks detracting from the proper appellate function. That is not what Shaw's case or Belbin's case was aiming at. Both cases intended to place firm limits on the scope for re-argument at the appellate hearing, while recognising that the appellate court is not obliged to find a judicial review type error before it can say that the judge's decision was wrong, and the appeal should be allowed. 26 The true approach is more simply expressed by requiring the appellate court to decide whether the decision of the district judge was wrong. What was said in the Celinski case and In re B (A Child) are apposite, even if decided in the context of article 8. In effect, the test is the same here. The appellate court is entitled to stand back and say that a question ought to have been decided differently because the overall evaluation was wrong: crucial factors should have been weighed so significantly differently as to make the decision wrong, such that the appeal in consequence should be allowed.”
“8. The delay is, of course, unfortunate but it is not as excessive as one finds in some other cases and it is necessary for the court to be well aware that there are considerable pressures upon the authorities in Poland and it is not always one single authority that is concerned, there may be one authority and another not perhaps liaising as closely as sometimes might be appropriate. 9. It is, in my judgment, quite wrong for this court to assume culpability in any delay unless it is so excessive or there are factors which indicate that it really was not reasonable for the authority to fail to issue a warrant earlier than it did.…”
“But the delay on the part of the state authorities, whether or not culpable, is not a trump card, however long. Its effect must be considered in the context of the particular facts of the case, and the question that must be addressed by a District Judge is how and to what extent delay impacts on the two aspects [public interest and family life] to which I have just referred.”
