In short, the case illustrates a very common situation in which, on the basis of what is often an appropriately diagnosed psychological condition or mental disorder, it is asserted that a litigant is not capable of participating in legal proceedings. In criminal cases, in relation to the accused, the issue is usually fitness to plead and stand trial. In civil proceedings the issue is litigation capacity. As is often the case, the court’s decision is influenced by how the litigant has functioned in previous cases or earlier in the instant proceedings.

F v W [2024] IEHC 631

The detail of this case is of relevance to dental experts and attention is drawn to the clarity and particularity with which Professor Harding set out the instances of treatment of the Claimant which was below the standard she could reasonably have expected and then identified the consequences thereof. There is a gastroenterological and pharmacological dimension to the case because it was alleged, and found, that the pain resulting from the negligent dental treatment necessitated treatment with NAISDs which caused ischaemic colitis. 

Bailey v Bijlani [2025] EWHC 175 (KB)

This is primarily a case for cardiologists, cardiac nurses and anaesthetists with a learning point for psychiatric experts. Viewed from outside the jurisdiction the striking feature of the case is that the plaintiff’s general practitioner records documenting a previous psychiatric history, which she had denied when assessed by the two psychiatric experts, were not disclosed to the defendant until five days into the trial.

Tynan v Bon Secours Health System Company Ltd by Guarantee [2025] IEHC 81 

This case has a number of important features of general interest. It illustrates the importance of assessing the reliability of a subject’s account. This is not the same as advising the court as to the reliability of the subject. It is the reliability of the account that is being assessed, not the reliability of the person giving the account. This is why it is good practice to open the Opinion section of an expert report with an introductory section sometimes headed ‘Evaluation of evidence’ or sometimes ‘Clinical plausibility’. That there was no challenge to the reliability of the experts’ evidence is not surprising. They explained how they assessed the appellant and the duration of the assessments.

ZA v Cornetu District Court, Romania [2025] EWHC 595 (Admin)

In the 11th episode of the Expert Matters Podcast, we take a look at how AI is being used by Expert Witnesses. We discuss general developments related to AI in the legal sector, hear from EWI member and computer expert Richard Marshall, listen to some of the ways AI is currently being used by Expert Witnesses, and discuss some dos and don'ts when using AI. As usual, we begin with our segment on 'What's going on at EWI?' and end with 'Newsreel', a quick fire discussion of the key things you need to know this month. 

This is a case in which the tribunal was critical of an expert witness. One criticism was that he did not expressly acknowledge the guidance provided in the Ikarian Reefer in his declaration – “a step taken by many experts who prepare reports for this Chamber”.

This is a case which will assume much greater importance for the 15 points of practice and practical steps that the judge decided can help reduce the risk of well-meaning professionals falling into pitfalls that hinder the identification of safeguarding issues at an early stage than as a case with learning points for experts.

For some of the experts in the fields from which jointly appointed experts were instructed, it illustrates how their evidence is tested and applied in a case of suspected fabricated or induced illness (FII).

Re N (Children: Fact Finding - Perplexing Presentation/Fabricated or Induced Illness) [2024] EWFC 326

Any uncertainty as to whether a psychiatrist can provide an expert report as a paper-based assessment is answered by this case.

In this case the paper-based assessment was sufficient for the court to conclude that, having regard to the Mental Capacity Act 2005, s 48, there were "reasons to believe that the Appellant lacks capacity". However, the fact that the court did not make a finding of a lack of capacity and transferred the case to a Tier 3 (High Court) Judge of the Court of Protection in order to determine the matter of capacity indicates how the court recognises how much more difficult it is to make a finding when the report relies on a paper-based assessment compared to a consultation with the subject of the report.   

MacPherson v Sunderland City Council (Rev1) [2024] EWCA Civ 1579 

In the last podcast for 2024, we look back at the ten key issues for expert witnesses that we've seen over the course of 2024, and highlight the ten things to look out for in 2025. From knowing and complying with your duties, to reevaluating and changing you opinion and handling fundamental dishonesty, this year in review has it all. 

The judge found that the evidence of the claimants' psychological expert fell well below the standard to be expected of a competent expert witness, both as to form and as to substance.
