“9 …[F]or a question of law to arise in the circumstances, the appellant must first identify the finding which is challenged; secondly, show that it is significant in relation to the conclusion; thirdly, identify the evidence, if any, which was relevant to that finding; and fourthly, show that that finding, on the basis of that evidence, was one which the tribunal was not entitled to make. What is not permitted, in my view, is a roving selection of evidence coupled with a general assertion that the tribunal's conclusion was against the weight of the evidence and was therefore wrong. A failure to appreciate what is the correct approach accounts for much of the time and expense that was occasioned by this appeal to the High Court.””
"Because of the delay in giving judgment, it has been incumbent on us to look with especial care at any finding of fact which is now challenged. In ordinary circumstances where there is a conflict of evidence a judge who has seen and heard the witnesses has an advantage, denied to an appellate court, which is likely to prove decisive on an appeal unless it can be shown that he failed to use, or misused, this advantage. We do not lose sight of the fact that the judge had transcripts of the evidence, as well as very extensive written submissions from counsel. But the very fact of the huge delay in itself weaken the judge's advantage, and this consideration had to be taken into account when we reviewed the material which was before the judge. In a case as complex as this, it is not uncommon for a judge to form an initial impression of the likely result at the end of the evidence, but when he has come to study the evidence (both oral and written) and the submissions he has received with greater care, he will then go back to consider the effect the witnesses made on him when they gave evidence about the matters that are now troubling him. At a distance of 20 months, [the trial judge] denied himself the opportunity of making this further check in any meaningful way." 54. These observations have been cited with approval in numerous subsequent authorities, including the Bank St Petersburg case. In that case at [80] the Chancellor also quoted what Lord Scott said in Cobham v Frett[2001] 1 WLR 1775 at p.1783 about what must be shown if excessive delay is to be relied on in attacking a judgment: "
