"We have decided not to set aside the whole of the decision and send it to a different Tribunal because we have dealt clinically with the submission made to us that what is required to be shown is delay plus some additional error. We do not consider that justice will be done by setting aside the whole of this decision, in the light of the consideration which we have given to it."
"Because of the delay in giving judgment, it has been incumbent upon 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 weakened 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, Harman J denied himself the opportunity of making this further check in any meaningful way."
"These matters leave me profoundly uneasy as to whether the Recorder did take proper advantage of the fact that he had seen and heard the witnesses."
"The danger in any case of this sort is that the Tribunal will have forgotten the impression created by witnesses."
"As to demeanour two things can be said. First, in their Lordships' collective experience, a judge rereading his notes of evidence, after the elapse of a considerable period of time can expect, if the notes are of the requisite quality, his impression of the witnesses to be revived by the rereading. Second, every experienced judge…is likely to make notes as a trial progresses, recording the impression being made upon him by the witnesses. Notes of this character would not, without the judge's permission or special request being made to him, form part of the record on an appeal…It is, in their Lordships' opinion, impermissible to conclude from the fact of a twelve-months' delay that the judge had a difficult task, let alone an 'impossible' one as Singh JA suggested, in remembering the demeanour of witnesses.""
