Case Updates

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.

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.

Johnston v Financial Ombudsman Service [2025] EWCA Civ 551

The Claimants brought an action against the Defendant, the Secretary of State for Education, for negligence and misfeasance in public office, relating to the actions of the Skills Funding Agency (‘SFA’), for which the Defendant is responsible. The Claimants alleged that the acts of SFA prevented them from selling their business for around £27 million, plus a lost chance of converting around £10 million in rollover loan notes.

The Defendant issued an application to revoke the Claimants’ permission to rely upon their forensic accounting expert evidence, because it had become clear that one of the Claimants, who was a trained accountant, had had significant secret involvement in the preparation of the expert’s report and the Joint Statement.

This judgment appears to provide some clarity on an issue about which seemingly conflicting advice is given to experts. It concerns the listing of documents and materials. 

Brown v Sterne [2025] NIMaster 15

The Petitioner, who was one of 15 candidates in an English Parliamentary By-Election, alleged that his vote count of 50 was fraudulently pre-determined. The expert statistician for the Petitioner based his opinion solely on the evidence of the Petitioner, which was contested. He was unaware of the contents of the Respondents’ witness statements and had not taken them into account.

This is an important judgment for experts instructed in cases where there is an issue as to whether thrombolysis should have been carried out following a stroke. The court considered a number of relevant publications.

For experts in psychiatry and psychology, it is important as it illustrates how the court tests evidence in cases involving performance validity testing.

Hakmi v East & North Hertfordshire NHS Trust [2025] EWHC 2597 (KB) 

The case was a claim in negligence arising out of complications following bariatric surgery. When he was asked during cross-examination to explain the Bolam test, the Claimant’s expert was not able to demonstrate an accurate understanding of, or ability to explain, the test.

One of the important differences between Ireland and other British Isles jurisdictions is in the procedures followed in personal injury litigation. This case is illustrative. If the plaintiff had brought his case in England or Wales, how would this case have progressed?

Keogh v O'Keeffe [2025] IEHC 26

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.
