“114. 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: Biogen Inc v Medeva plc [1977] R.P.C.1; Piglowska v Piglowski [1999] 1 W.L.R. 1360; Datec Electronics Holdings Ltd v United Parcels Service Ltd[2007] UKHL 23 ; [2007] 1 W.L.R. 1325; Re B (A Child) (Care Proceedings: Threshold Criteria)[2013] UKSC 33 ; [2013] 1 W.L.R. 1911 and most recently and comprehensively McGraddie v McGraddie[2013] UKSC 58 ; [2013] 1 W.L.R. 2477. These 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. 115. It is also important to have in mind the role of a judgment given after trial. The primary function of a first instance judge is to find facts and identify the crucial legal points and to advance reasons for deciding them in a particular way. He should give his reasons in sufficient detail to show the parties and, if need be, the Court of Appeal the principles on which he has acted and the reasons that have led him to his decision. They need not be elaborate. There is no duty on a judge, in giving his reasons, to deal with every argument presented by counsel in support of his case. His function is to reach conclusions and give reasons to support his view, not to spell out every matter as if summing up to a jury. Nor need he deal at any length with matters that are not disputed. It is sufficient if what he says shows the basis on which he has acted. These are not controversial observations: see Customs and Excise Commissioners v A[2002] EWCA Civ 1039 ; [2003] Fam. 55; Bekoe v Broomes[2005] UKPC 39 ; Argos Ltd v Office of Fair Trading[2006] EWCA Civ 1318 ; [2006] U.K.C.L.R. 1135.”
“…the 5 August letter is a document providing only flimsy support for Mr Estridge’s case, whether or not Mr Tohidi signed it.”
“It is commonplace in civil litigation for parties to advance rival evidential cases, and support them by single-minded submissions, but for the judge to find that the truth lay not at the opposing ends of the spectrum thereby created but somewhere in the middle. This is, as Mr John rightly submitted, a classic example of such a case. To suggest that the judge was constrained to opt for one or the other of the two extremes contended for would be to impose an unrealistic, mechanistic and unjust fetter upon the trial judge.”
“Mr Tohidi’s evidence under cross examination was that he did not, at the time, genuinely believe that he owed money to Mr Estridge is only something that he has now been able to demonstrate, but which he was not able to do so at the time, and so felt pressured to accept Mr Estridge’s version of their account together.”
