“Role of an expert Whilst giving the unanimous decision of the Supreme Court in Griffiths v TUI UK Limited[2023] UKSC 48 at 36, Lord Hodge stated that: ‘It is trite law that the role of an expert is to assist the court in relation to matters of scientific, technical or other specialised knowledge which are outside the judge’s expertise by giving evidence of fact or opinion but the expert must not usurp the function of the judge as the ultimate decision-maker on matters that are central to the outcome of the case.’”
“Duty to restrict expert evidence Expert evidence shall be restricted to that which is reasonably required to resolve the proceedings.”
“68. But that is not the correct approach to the admissibility of the evidence. Instead it is necessary to look at the pleaded issues and, unless and until a particular issue is excluded from consideration underCPR 3.1 (2)(k), the court must ask itself the following important questions: (a) The first question is whether, looking at each issue, it is necessary for there to be expert evidence before that issue can be resolved. If it is necessary, rather than merely helpful, it seems to me that it must be admitted. (b) If the evidence is not necessary, the second question is whether it would be of assistance to the court in resolving that issue. If it would be of assistance, but not necessary, then the court would be able to determine the issue without it (just as in Mitchell the court would have been able to resolve even the central issue without the expert evidence). (c) Since, under the scenario in (b) above, the court will be able to resolve the issue without the evidence, the third question is whether, in the context of the proceedings as a whole, expert evidence on that issue is reasonably required to resolve the proceedings. In that case, the sort of questions I have identified in paragraph 63 above will fall to be taken into account. In addition, in the present case, there is the complication that a particular piece of expert evidence may go to more than one pleaded issue, or evidence necessary for one issue may need only slight expansion to cover another issue where it would be of assistance but not necessary.”
