Case Updates

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.

LB Croydon v D (critical scrutiny of the paedeatric overview)

The judge determined that the proposed expert evidence, to support the existence of a money laundering scheme, was not admissible and, even if admissible, was neither necessary nor of assistance to the court.

The parties sought permission to rely on expert evidence from three experts in respect of the claimant’s tazkira, an official identity document issued by the former Islamic Republic of Afghanistan. The judge found the first proposed expert’s evidence to be hearsay, and (if the proceeding continued) directed the parties to re-serve the second expert’s report with evidence for which permission had not been given excised, and to re-serve the third expert’s report with a compliant declaration.  

MS, R (on the application of) v Kent County Council [2024] EWHC 2661 (Admin)

The judge determined that the evidence of the defendant’s expert on the mental health of a man detained by the police was to be preferred in every respect over the claimant’s expert because he had relevant experience of the matters in respect of which he was giving evidence and adopted the right approach.

In this patent case, the judge noted that neither expert was a native English speaker and both had difficulties with questions put to them during cross-examination. The misstep of one expert over the word “buckling”, which he had used in his report, and his use of a translator during cross-examination for reference, led the judge to approach his written evidence with a degree of caution.

Salts Healthcare Limited v Pelican Healthcare Limited [2025] EWHC 497 (Pat)

The judge in this claim for professional negligence struck out a witness statement which contained paragraphs which were pure opinion, made by the witness as a self-proclaimed expert, noting that it was expert evidence by the back door, in contravention of CPR Part 35 and plainly abusive.

While the Judge in this extradition appeal ultimately reached the same conclusion as the District Court Judge, and dismissed the appeal, he pointed out significant deficiencies in how the District Court Judge had treated the expert psychological evidence.

The judge preferred the evidence of the Claimant's expert because of the Defendant's expert’s approach to his task as expert, his confusion over the proper approach to what prior art was and was not in the common general knowledge, the number of assertions he made which he was forced to resile from as incorrect, and his failure to acknowledge a key fact.

The judge found that the forensic accounting expert’s approach of forming an opinion as to the value of the Company, then carrying out a detailed calculation and only if it matches his initial opinion accepting it, undermined the credibility and reliability of his opinion as to the value of the Company.

In considering whether the claimant should be required to provide a breakdown of expert and medical agency fees, the judge decided to offer the claimant the option of either providing the breakdown of expert and medical reporting organisation fees, to enable an assessment of work of both the expert and the MRO, or not providing that information and having the expert fees assessed on the hypothetical basis that there was no medical reporting organisation involved.
