The judge noted that that the manner in which two Expert Witnesses in Chartered Surveying gave their evidence was more advocacy than opinion, with one expert’s report reading more like a skeleton argument.

In the circumstances of the case, including the absence of a timely challenge to lack of form, the judge gave due weight to an expert report and the answers to questions without subtraction for lack of compliance with CPR 35 and rule 3 of the Practice Directions.

The court considered that there was some substance to the criticisms of an accident and emergency expert for not dealing with matters in his primary report which he then agreed in the joint report with the opposing expert (who had included the issues in his primary report). These were however criticisms for failing to deal with points, rather than criticisms of the opinions he actually expressed in his primary report.

In this appeal of an asylum decision, the court was unable to discern sustainable and tolerably clear reasons as to why the judge rejected the expertise of the expert witness and his expert opinion provided in his report.

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.
