Our day in the life series provides examples of the kind of work undertaken by our members across a range of different professional backgrounds.

An expert report that is entirely equivocal on the key issues is of little assistance to the court

The court noted that the jointly instructed expert demonstrated a clear lack of understanding of both CPR 35 and the duties owed to the court by an expert in allowing someone else in this firm to answer CPR 35 questions on his behalf. His report was also entirely equivocal on the key issues and therefore offered little or no assistance to the court.

The diagnosis hang-up and cardiological manifestations of PTSD

The diagnosis hang-up and cardiological manifestations of PTSD

In this road traffic accident case where there was a claim for psychiatric injury, the two psychiatric experts produced between them 14 reports, including addenda and other admissible communications. The fundamental disagreement was the diagnosis: PTSD or adjustment disorder. It appears that four of the reports by the defendant’s expert were in rebuttal of the opinion of the plaintiff’s expert. This summary does not reflect the considerable extent to which the court had to analyse the evidence as to diagnosis. In the court’s judgment diagnosis hardly mattered. The judge said that more important, in his view, was the impact that the condition had on the plaintiff’s everyday functioning and lifestyle. Then when awarding damages, he said that the psychiatric damage suffered by the plaintiff attributable to the accident could be described as moderately severe whether that be under a diagnosis of post-traumatic stress disorder or psychiatric damage generally.

Disability and exclusion from school

Disability and exclusion from school

There was no dispute about the expert evidence in this case but it is of interest for several reasons. First, it sets out in some detail the evidence of experts in educational psychology and occupational therapy and it therefore provides examples for those healthcare specialties of how to make their bodies of knowledge understandable to a tribunal. Second, it illustrates the role of experts when their evidence is admitted by a specialist tribunal. Third, it sets out the test of which experts need to be aware in cases of alleged disability discrimination arising from a school’s treatment of a pupil with behavioural difficulties. Fourth, although psychiatrists and psychologists are often advised to keep the unconscious out of the witness box, for reasons to do with proof, it is encouraging to find a tribunal accepting such evidence.

The judge found that one of the GP experts had trespassed on the judicial function to determine the facts and had sought to advocate on behalf of the second defendant.

Rough or inappropriate handling of an infant
Case Updates

Rough or inappropriate handling of an infant

As in many family cases, the issue here was the cause of the child’s injuries. It includes a distinction to be made between handling in hospital, such as holding of wrists for blood to be drawn, application of masks to assist breathing and holding of head still, to what would be expected in a normal domestic setting. It illustrates how a CMV infection complicated the court’s analysis of the evidence.
