“41. There are of course only limited circumstances in which an appellate Court should interfere with a finding of fact made by a trial judge. Thus in Henderson v Foxworth Investments Ltd[2014] UKSC 41 ,[2014] 1 WLR 2600 , Lord Reed (with whom Lords Kerr, Sumption, Carnwath and Toulson agreed) said at paragraph 67: “in the absence of some other identifiable error, such as (without attempting an exhaustive account) a material error of law, or the making of a critical finding of fact which has no basis in the evidence, or a demonstrable misunderstanding of relevant evidence, or a demonstrable failure to consider relevant evidence, an appellate court will interfere with the findings of fact made by a trial judge only if it is satisfied that his decision cannot reasonably be explained or justified.”
