The Annual Sir Michael Davies Lecture for 2025 was held on 15 October at the RAF Club in London. The Right Honourable Lady Simler, Justice of the Supreme Court, delivered an insightful lecture on Enhancing Expert Evidence: Reports, Opinions, and Judicial Perspectives, which was summed up perfectly by EWI Chair Sir Martin Spencer as the blueprint for providing the best written and oral expert evidence.

The Claimants alleged that dust, noise and odour emitted by the defendant’s factory over a prolonged period constituted a legal nuisance. The judge was critical of the Claimants’ experts for departing from the initial common approach when the initial results had been adverse to their clients’ case.

There are some general learning points for all experts but otherwise this is for neurosurgeons. It is another road traffic accident personal injury case in which the court needed the assistance of neurosurgeons, or at least it would have done but for the fact that it made a finding which made it unnecessary to consider the neurosurgical evidence before reaching a judgment. The nature of the injuries sustained by the claimant were not in dispute. What was in dispute, but ultimately irrelevant, was what the child’s injuries would have been if the driver of the vehicle had been driving (non-negligently) at a lower speed than he was. It was on this point that the neurosurgical experts disagreed.

MW v Wilkinson [2025] EWHC 2300 (KB) 

The person insured by the defendant drove his motorcycle into the pursuer’s parked lorry causing the pursuer, who claimed he was standing on the steps of the lorry on one foot and leaning on the cab, to allegedly lose his balance and suffer injuries. The defendant led an expert witness, Mr H, who presented himself as a Forensic Engineer, and the pursuer an Orthopaedic expert, Mr S. 

The Sherrif concluded that he could not afford Mr H’s conclusions more than minimal weight because of a failure of methodology. Mr H had also expressed his conclusions in terms that gave the appearance that he was the decision-maker and made concessions during cross-examination. The Sherrif found Mr S to be a credible and reliable witness overall but noted that he was not clear when describing his fee arrangements. 

This is an important judgment for obstetricians as it shows in precise detail how the court, relying on not just the experts’ evidence but a critical analysis of the literature on which they relied, decided whether the claimant would have avoided developing HELLP had she been advised to take 75 mg aspirin at 12 (or 14) weeks instead of at 23. Twelve publications were put under the microscope and considered also in the light of research concerning the relative value of aggregate data and individual participant data.

Although the issue in this case was the prevention of HELLP, it may be an important judgment to consider in pre-eclampsia cases.

De Francisci v Hampshire Hospitals NHS Foundation Trust (County Court, Basingstoke sitting at Southampton, 9 May 2024) Case No: F16YM828

There have been a number of cases illustrating how fractures are dated. This case illustrates the dating of haemorrhages as well as fractures. The judge’s structure of her judgment enables the reader to see how the analysis of the evidence of the various experts allowed her to find as fact how many incidents of non-accidental injury there were and when they occurred as well as with what force. Although there are no extracts from the experts’ reports or evidence, the judgment illustrates how properly presented expert medical evidence can assist the court in cases of suspected non-accidental injury. The dating of injuries can be of critical importance in cases, as here, where there was more than one potential perpetrator. 

London Borough of Y v M [2025] EWFC 232 (B) 

The detail of this judgment is for the specialists. It illustrates the challenges of proving that an infection has been caused by food poisoning at a hotel, and specifically the relevance of evidence as to other outbreaks in the area, trips out of the hotel, the records of illnesses suffered by other residents and audits of hotel food standards. The two learning points are oft-repeated ones and in this case of particular importance as some of the judge’s decisions depended on which expert’s evidence to accept.

Dr Richard Taylor is an Expert in the identification, verification and valuation of diamonds, gemstones, jewellery, watches, silver and antiques. He tells us how got into Expert Witness work, what he loves about it, and why he likens being cross-examined to playing chess.

Fans of true crime and anyone involved in giving expert evidence might be interested in a recent podcast episode from EWI Fellow, Dr Harry Brunjes.

The claimant alleged that the vibrating tools he used while employed by the defendant caused Hand-Arm Vibration Syndrome. The judge criticised one of the medical experts for looking for answers that supported his strong views on the subject, rather than obtaining a reliable history from the claimant.
