Expert Matters - The Podcast

The Claimant alleged that an accident five years earlier was the cause of the amputation of his lower leg. The judge criticised the Claimant’s orthopaedic expert, Professor H, for demonstrating at times a rather ‘loose approach’ to his expert evidence and a closed mindedness towards his evidence.

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.

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.

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 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.

In the 14th episode of the Expert Matters Podcast, Simon and EWI's Marketing and Events Manger, Heather George, reflect on their highlights from EWI's 2025 Annual Conference which was held on 20 June. The Conference featured a great line-up of panels and speakers, with keynote speeches from Lady Rose, Justice of the Supreme Court, and Lord Justice Birrs, the Deputy Head of Civil Justice. A wide range of lawyers, judges and expert witnesses joined the panel sessions, and EWI member Dr Richard Marshall provided an insightful session on AI and the Expert Witness.

Mrs Justice Joanna Smith provides an incredibly useful judgment following the hearing at the High Court in March of this year. Previous case law and legal tests for gross misconduct were addressed and applied given that such allegations underpinned the case.  The parties adduced expert evidence to establish the value of shares on the assumption that warranties had been breached.This update focuses on both experts’ evidence given that the approaches were significantly different and that one was clearly preferred over the other.
