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. 

The claimant brought an action against two of its founding shareholders, and companies owned or controlled by them, seeking compensation for harm caused by their alleged participation in a fraudulent scheme. The forensic accounting expert for the first defendant failed to inform the court, until shortly before he gave evidence, that he had ceased to hold a key professional membership.

The claimant asserted that the defendant was required to transfer title in a vessel at the expiry of the bareboat counterparty between them. The judge noted that the claimant’s witness on insurance broking had essentially no experience in the matter for expert evidence and his views appeared to be based on conversations with unidentified others, rather than his own experience of testable research.

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.

The Claimant brought a claim for compensation in the UK after he was hit by an uninsured driver while on holiday in Mallorca and suffered major injuries, including severe brain injuries. The court found the evidence of several of the experts to be unsatisfactory leading the judge to preface his assessment of the expert witnesses with the observation that “[t]he court is not bound by the conclusions of any expert if it offends logic and common sense. We do not have trial by experts.”

The Claimant brought a claim of clinical negligence after suffering a rare but serious complication (anal stenosis) of an operation performed by the Defendant to surgically remove her haemorrhoids. The judge found that the evidence of the Claimant’s expert was based on limited experience or expertise. There were also several instances where he had not acted in accordance with his duties as an expert.

The judgement from The Honourable Mr Justice Trower asserts that Expert Witnesses have a duty to disclose previous criticisms of their evidence in judgments.

The Claimant sought damages for clinical negligence from the Defendant who, she asserted, failed to diagnose red flag symptoms of cauda equina syndrome at a face to face consultation. The Claimant’s neurorehabilitation expert prepared his reports, engaged in an expert discussion, and signed the Joint Statement, without having seen the Claimant’s witness statement or the reports of other relevant experts.

Although this is a case of alleged dental negligence and can be usefully read in full not only by dental experts, but by dentists, oral surgeons and students of dentistry, it is also of some general significance not just for experts who provide evidence in Scotland, for whom the exposition of Scots negligence law is invaluable and civil procedure significantly different, but for lessons about expert evidence in clinical negligence cases generally.
