The claimants, who claimed to have suffered personal injury caused by contaminants in a housing development, relied on the evidence of Professor T. The court found that Professor T did not provide any medically reasoned justification which would allow the court to make findings supporting his conclusions and did not explain in detail how he was able to reach his view on causation. The detail of this judgment is important for toxicology experts. It may be useful for medical experts as an example of the courts’ approach to causation.

R v Mazzer [2024] EWCA Crim 557

This successful appeal against a Family Court judgment which led to the removal of two children from the care of their parents turned primarily on the fact that the judge was found to have acted as her own expert and conducted her own analysis of the medical research material making findings that were not supported by evidence. For paediatricians, radiologists, neurosurgeons and ophthalmologists this is highly recommend reading about the courts’ analysis of expert evidence relating to abusive head trauma and low level falls.    

A claimant who sustained a moderately severe brain injury when she fell off a pier was found by the judge to have been been fundamentally dishonest.

An expert report did not address all of the questions posed in the letter of instruction, reformulated other questions, and failed to comply with FPR Part 25 in a number of important ways, while the expert witness's oral evidence failed to provide an impartial expert view. 

An expert is entitled to revise his or her opinion in light of a judge's finding as to what is or is not required in order to comply with particular regulations or equivalent regulatory standards.

An expert opinion must be supported by reasoning and correctly apply the relevant legal tests. 

The report of the psychiatrist expert witness strayed outside his expertise. It did not show any clear independent knowledge, demonstrate that that he was a country expert, or provide supporting source material.
