Day in the life of an Expert Witness

Our day in the life series provides examples of the kind of work undertaken by our members across a range of different professional backgrounds.

Disability and exclusion from school

Disability and exclusion from school

There was no dispute about the expert evidence in this case but it is of interest for several reasons. First, it sets out in some detail the evidence of experts in educational psychology and occupational therapy and it therefore provides examples for those healthcare specialties of how to make their bodies of knowledge understandable to a tribunal. Second, it illustrates the role of experts when their evidence is admitted by a specialist tribunal. Third, it sets out the test of which experts need to be aware in cases of alleged disability discrimination arising from a school’s treatment of a pupil with behavioural difficulties. Fourth, although psychiatrists and psychologists are often advised to keep the unconscious out of the witness box, for reasons to do with proof, it is encouraging to find a tribunal accepting such evidence.

Philipa Hodgson v Dr Daniel Hammond & Anor [2025] EWHC 1261 (KB)

The claimant brought a clinical negligence claim against two general practitioners alleging that they failed to act on a potential diagnosis of pelvic inflammatory disease. The judge found that one of the GP experts had trespassed on the judicial function to determine the facts and had sought to advocate on behalf of the second defendant.

Rough or inappropriate handling of an infant

Rough or inappropriate handling of an infant

As in many family cases, the issue here was the cause of the child’s injuries. It includes a distinction to be made between handling in hospital, such as holding of wrists for blood to be drawn, application of masks to assist breathing and holding of head still, to what would be expected in a normal domestic setting. It illustrates how a CMV infection complicated the court’s analysis of the evidence.

N, In the Matter Of [2024] EWFC 378 

Unresponsive episodes in a child and the role of chloral hydrate

Unresponsive episodes in a child and the role of chloral hydrate

For the specialists this case illustrates how the court investigates case of perplexing presentations in children and the importance of considering as many as possible explanations. This was a case where the medical history was complex and where the material events occurred over a 5 months’ admission, so the volume of medical records must have been immense. The court was obviously greatly assisted by the expert factual evidence of one of the child’s consultants, specifically his summary of the child’s medical conditions and his table of medication. The weakness of one of the experts was that he had not sufficiently familiarised himself with the contents of the medical records and was not as familiar as with the chronology of the case as he might have been if he had created a chronology in his own investigation of the case.

The claimants, who carried on a business breeding falcons, made allegations of harassment and nuisance against their neighbour, who operated a small farm neighbouring their property. While the judge accepted some of the claimants’ criticisms of one of the defendants’ experts, he also noted that the claimants could not complain about the consequences of their putting in new evidence that was not in accordance with the timetable laid down at the CCMC.

Aerotoxic syndrome
Case Updates

Aerotoxic syndrome

Personal injury claims are being brought by approximately 220 pilots and cabin crew at the High Court in London on the grounds of aerotoxic syndrome (ATS). This group of claimants includes 51 claims which were issued by Thompsons in March 2019 involving pilots and cabin crew working for EasyJet, British Airways, Thomas Cook, Jet2 and Virgin Atlantic. These two claims are not included in these ongoing English collective proceedings. These were claims by two pilots who lost the chance of bringing successful claims as a result of the admitted negligence of a Scottish law practice.

Attention deficit hyperactivity disorder, dyslexia and litigation capacity
Case Updates

Attention deficit hyperactivity disorder, dyslexia and litigation capacity

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.
