One of the key roles of the Expert Witness Institute (‘EWI’) is to ensure that policy, rule and regulatory changes are informed by the experience of our members, and the needs of the expert witness community and the wider justice system. In this update, we discuss key policy developments and our advocacy work over the last couple of months. 

Veterinary surgeon, Jeremy Stattersfield, has been guiding courts on veterinary medicine since 1981. He told us how he got into the Expert Witness world; what motivates him; and shares his observations and advice for Experts from all professions.

In January's episode of the Expert Matters Podcast, we discuss responding to written questions. We look at the rules and regulations, discuss a couple of recent cases, and offer some advice, before hearing the thoughts of some of the members of our Editorial Committee. We also discuss our new Guidance which is linked below. As always, you can also listen to our 'What's going on at EWI' and 'Newsreel' segments to keep up-to-date on the latest developments in the world of expert witnesses and expert evidence. 

The claimant, who suffered brain damage at birth, relied on a report commenting on the allegation of negligence prepared by Mrs S, a midwife. The judge was concerned about the objectivity of Mrs S’s expert evidence because she was heavily involved in the business of litigation and gave evidence which he considered was uncompromisingly critical of the defendant.

The judge found that the report by the claimants’ forensic accounting expert was not expert evidence because it simply reported what the underlying documents said in a more digestible way, without adding any expert opinion. On the one or two occasions where the expert did offer an opinion, they were not opinions on any accountancy matter.

EWI Chief Executive Officer, Simon Berney-Edwards, shares his thoughts on 2025, a year where Expert Witnesses have continued to come under increasing scrutiny.

The Claimant, on her solicitor’s advice, covertly recorded her testing by the Defendant’s neuropsychological expert. Weighing up the factors in favour of admitting the evidence and against admitting it, the judge considered that they were very finely balanced and quite difficult and that he may well have ruled that the evidence could not be relied on, if the Defendant’s expert had not himself inadvertently recorded the testing.

The task for the expert in this case was enormous. Capacity is issue specific. This means that if the issue is someone’s capacity to conduct legal proceedings, in this case sixteen sets of proceedings, the expert has to consider each set of proceedings. The person may have the capacity to conduct some and not others.
