“Appellate courts have been repeatedly warned, by recent cases at the highest level, not to interfere with findings of fact by trial judges, unless compelled to do so. This applies not only to findings of primary fact, but also to the evaluation of those facts and to inferences to be drawn from them. The best known of these cases are … all decisions either of the House of Lords or of the Supreme Court. The reasons for this approach are many. They include: i. The expertise of a trial judge is in determining what facts are relevant to the legal issues to be decided, and what those facts are if they are disputed. ii. The trial is not a dress rehearsal. It is the first and last night of the show. iii. Duplication of the trial judge’s role on appeal is a disproportionate use of the limited resources of an appellate court, and will seldom lead to a different outcome in an individual case. iv. In making his decisions the trial judge will have regard to the whole of the sea of evidence presented to him, whereas an appellate court will only be island hopping. v. The atmosphere of the courtroom cannot, in any event, be recreated by reference to documents (including transcripts of evidence). vi. Thus even if it were possible to duplicate the role of the trial judge, it cannot in practice be done.” i.
