Case Updates

This case, in the Court of Protection, concerned whether a wealthy, elderly man lacked capacity. The judgment dealt primarily with an application by respondents 2-7 to replace the jointly instructed expert with a new expert or, at the very least, permission for them to instruct their own expert.   

The judge did not find grounds to end the Single Joint Expert’s instruction but was satisfied that permitting respondents 2-7 to obtain a further report was appropriate in this particular case.

In straying from their original instructions, the expert developed an opinion without all the facts of the case and the second claimant was being coached through his cross-examination using smart glasses.

The dispute was between a former husband and wife, who were Russian nationals, about a post-nuptial agreement. The judge found that much of the expert evidence on Russian law was misdirected and misspent, and of limited use. He emphasised that both experts acted at times as surrogate advocates on behalf of their instructing parties.

The claimant was involved in a minor road traffic accident while she was the passenger in a car driven by her partner, who was the defendant’s insured. She claimed compensation for whiplash and psychological symptoms. The judge described the report of the physiotherapist expert witness who acted for the claimant as almost worse than useless and aspects of her evidence as literally unbelievable

The claimants, who own a property adjoining with the properties of the defendants, complained that the defendants engaged in various acts of trespass on, and damage to, their property. The claimants’ expert, who replaced a retiring expert, referenced and relied on a key, but erroneous, “fact” in his predecessor’s report without checking it.

The claimant alleged that the second defendant, a Spanish racing driver, had repudiated a binding agreement under which he was contracted to drive for the claimants’ IndyCar team for the 2024, 2025 and 2026 racing seasons. The judge found some of the expert witnesses to be impressive and independent, while the expert evidence of others was unimpressive and disappointing.  

The case was a group litigation concerning extensive oil pollution which affected two regions in the Niger Delta in Nigeria. The judge rejected the strident criticism of the experts who were called to provide evidence on aspects of Nigerian law.

The defendant was contracted, during the Covid lockdowns, to source and supply sterile gowns, which the claimant subsequently asserted were not contractually compliant. Issues for expert evidence included the sterility of the gowns and whether the claimant could have mitigated the loss by resale.

The Court excluded consideration of the expert testimony of an expert on the dangers of AI and misinformation, after he submitted an expert declaration which included fake AI-generated citations to two academic articles.

The two handwriting experts in this case were given completely different samples of comparator signatures and did not undertake the same task. The judge noted that it was extraordinary and unsatisfactory that the defendants’ expert was provided with comparator signatures which were not the person’s normal signature and was then instructed to assume they were authentic.
