“The Correct Approach on Appeal

This is another important matter, and it is appropriate to summarise the correct approach at this stage. A finding that an activity is or is not targeted at consumers in the UK necessarily involves an evaluation by the judge of a range of different facts and matters. It requires, in other words, a multifactorial assessment of the documents, the evidence and the submissions made by the parties. The evaluation is also one which, when made in that way, the trial judge is peculiarly well placed to carry out.

Conversely, an appeal court is inevitably at a disadvantage, as Lord Hoffmann explained in Biogen Inc v Medeva plc [1997] RPC 1 at 4, and so, where the application of a legal standard such as negligence or obviousness involves no question of principle, but is simply a matter of degree, an appellate court should be very cautious in differing from the judge’s evaluation.

We consider that the position was well summarised by Lewison LJ in Fage UK Ltd v Chobani UK Ltd [2014] EWCA Civ 5; [2014] FSR 29; [2014] ETMR 26 in these terms at para 114:

That does not, however, mean the appeal court is powerless to intervene where the judge has fallen into error in arriving at an evaluative decision such as whether an activity was or was not targeted at a particular territory. It may be possible to establish that the judge was plainly wrong or that there has been a significant error of principle; but the circumstances in which an effective challenge may be mounted to an evaluative decision are not limited to such cases. Many of the important authorities in this area were reviewed by the Court of Appeal in In re Sprintroom Ltd [2019] EWCA Civ 932; [2019] BCC 1031, at paras 72–76. There, in a judgment to which all members of the court (McCombe LJ, Leggatt LJ and Rose LJ) contributed, the court concluded, at para 76, in terms with which we agree, that on a challenge to an evaluative decision of a first instance judge, the appeal court does not carry out the balancing exercise afresh but must ask whether the decision of the judge was wrong by reason of an identifiable flaw in the judge’s treatment of the question to be decided, such as a gap in logic, a lack of consistency, or a failure to take into account some material factor, which undermines the cogency of the conclusion.

On the other hand, it is equally clear that, for the decision to be “wrong” under CPR 52.21(3), it is not enough to show, without more, that the appellate court might have arrived at a different evaluation.”

“The approach to be followed in perversity challenges to decisions of specialist Tribunals … is simply a reflection of the respect which is naturally paid to the decisions of a specialist Tribunal in an area where it possesses a particular expertise. Given such expertise in a Tribunal, it is entirely understandable that a reviewing court or Tribunal will be slow to interfere with its findings and evaluation of facts in areas where that expertise has a bearing. This may be regarded not so much as requiring that a different, enhanced standard must be met as an acknowledgement of the reality that an expert Tribunal can normally be expected to apply its expertise in the course of its analysis of facts ….”

“Essentially, the judicial task is twofold: to enable the parties to understand why they have won or lost; and to provide sufficient detail and analysis to enable an appellate court to decide whether or not the judgment is sustainable.”

“ … It has also been recognised that a generous interpretation ought to be given to a tribunal’s reasoning. It is to be expected, of course, that the decision will set out the facts. That is the raw material on which any review of its decision must be based. But the quality which is to be expected of its reasoning is not that to be expected of a High Court judge. Its reasoning ought to be explained, but the circumstances in which a tribunal works should be respected. The reasoning ought not to be subjected to an unduly critical analysis.”

Where permission is granted to appeal on the grounds that the judgment does not contain adequate reasons, the appellate court should first review the judgment, in the context of the material evidence and submissions at the trial, in order to determine whether, when all of these are considered, it is apparent why the judge reached the decision that he did. If satisfied that the reason is apparent and that it is a valid basis for the judgment, the appeal will be dismissed. … If despite this exercise the reason for the decision is not apparent, then the appeal court will have to decide whether itself to proceed to a rehearing or to direct a new trial.

….

... There are two lessons to be drawn from these appeals. The first is that, while it is perfectly acceptable for reasons to be set out briefly in a judgment, it is the duty of the judge to produce a judgment that gives a clear explanation for his or her order. The second is that an unsuccessful party should not seek to upset a judgment on the ground of inadequacy of reasons unless, despite the advantage of considering the judgment with knowledge of the evidence given and submissions made at the trial, that party is unable to understand why it is that the judge has reached an adverse decision.” ”
