Experts, in particular medical experts, are likely to be familiar with experts’ discussions that take place after the exchange of reports. This case referred to a circumstance more commonly, or perhaps seldom otherwise, encountered in the Technology and Construction Court. 

This case is about whether the judge erred in finding that Ms Soophia Khan had capacity to defend proceedings for contempt of court. This is an important judgment for any psychiatrist called upon to assess fitness to plead and stand trial in a criminal case or litigation capacity in a civil case; and important also for any psychologist whose evidence may be considered in such a case. It is not just because it compares the tests for fitness to plead and stand trial and litigation capacity; it is a rare illustration of not only how a judge at first instance assesses expert evidence in such a case but also of how the court of appeal analyses the judicial reasoning when such a case is appealed.

In this US case, an expert in fiduciary services used Microsoft’s Copilot to cross-check calculations he used in expert evidence.

The claimants objected to the wording of a question for the expert witnesses in marine engineering because it invited the experts to express an opinion on a matter of fact which is ultimately for the court.

Although accepting the medical expert's conclusion on the First Defendant's capacity to appear in court, the Bailiff noted that any further application for an adjournment on health grounds would require a much more significant explanation of the First Defendant's medical history, and precise problems and prognosis, to be provided well in advance.

The judge found that it was without justification and entirely unecessary for an expert to question the opposing expert's professionalism and motives in selecting evidence, noting that this approach was unhelpful for the tribunal. 

The court could see no basis on which the plaintiffs could seek to rely on any agreement reached between the experts as to the underlying facts.
