For paediatricians this is an example of how not to conduct an expert paediatric assessment and present the results to the court. It also illustrates some basic points applicable to all experts.

M v F [2025] EWFC 150 (B)

The claimant alleged both negligence and breach of contract by the defendant designer of a container park near Felixstowe Port. The judge set out the reasons why she was not impressed by the claimant’s expert and treated his evidence with significant caution.

MJS Projects (March) Limited v RPS Consulting Services Limited [2025] EWHC 831 (TCC)

Dr. Rohit Seth is trained in Plastic, Reconstructive, Aesthetic and Hair Transplant Surgery with over 20 years of surgical experience. A practicing clinician and Expert Witness, he shares how he balances a busy private surgical career with expert reporting and what makes this work both intellectually rigorous and professionally rewarding.

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.

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.

The Claimant claimed he had suffered a substantial loss due to the destruction of two consignments of poppy heads by the Defendants. The parties were given permission to rely on the written evidence of expert accountants. The Claimant made an application to the Court for the accountancy expert witnesses to give oral evidence at the trial and an application to adduce evidence prepared by his son.

This was a significant and well reported patent case which was determined in the Intellectual Property List within the High Court last autumn.   

The technical aspects of the case required significant expert input from the panel involved.  The cross-examinations performed by leading Counsel for the parties were lengthy and complicated.  This led to confusion over what evidence was given when the transcripts were re-visited on subsequent trial days. The case shows how consideration should be given to experts who are being cross-examined so not to overload them with questions and information on the stand.

The expert paediatrician in this case misidentified and confused twins when reading the primary medical disclose. This fundamental error was of seminal importance in this case because the twins had very different birth and post-birth experiences, with one being much weaker and more vulnerable than the other.  The judge noted that the cross-examination of the expert was nothing short of a demolition of the expert’s evidence.
