The EWI has just released its new Guidance on Being instructed as a Single Joint Expert with invaluable and easily accessible information and advice for members who act as a Single Joint Expert. 

The Lady Chief Justice has issued the fourth amendment to the Criminal Practice Directions 2023 which includes changes to chapter 7 (Expert Evidence), including amendments to expert declarations of compliance.

A mother applied to set aside what she submitted were findings made five years ago by a district judge concerning the party’s two children in reliance upon a report prepared by Ms G. The court found that there was no doubt at all that the harm that Ms G put forward arose, in her view, from what she regarded as the mother’s behaviour in alienating the children. Ms G had carried out an assessment of the mother which included her own attachment and other behaviours, but that did not form a finding of fact about how the mother actually behaved. Therefore there were no findings with a solid foundation that the mother alienated the children even though the judge expressed it as such, and accordingly no findings to actually set aside.

The Claimant alleged that an accident five years earlier was the cause of the amputation of his lower leg. The judge criticised the Claimant’s orthopaedic expert, Professor H, for demonstrating at times a rather ‘loose approach’ to his expert evidence and a closed mindedness towards his evidence.

The Civil Procedure Rule Committee is undertaking a consultation regarding the effectiveness of the extension of Fixed Recoverable Costs (FRC), inviting feedback as part of an evidence-gathering initiative conducted in collaboration with the Ministry of Justice (MoJ). You can input into the EWI response by completing a survey of the consultation questions. 

It is not easy to appreciate the significance of this judgment for experts in general without reading the summary so the ‘Commentary’ is at the end. The neuropsychological test results are perhaps not of particular interest to psychologists and psychiatrists at this stage in the proceedings but may become so if the case does not settle and it goes to trial.

The Claimant’s father and litigation friend alleged that the medical practitioners treating his son were negligent in not promptly carrying out an ultrasound on his head, after he had been admitted to hospital with head injuries. The judge found that the expert for the Claimant was, to an extent, seeking to fight his corner rather than taking a dispassionate approach to the issues raised.

One of the key roles of the Expert Witness Institute (‘EWI’) is to ensure that policy, rule and regulatory changes are informed by the experience of our members, and the needs of the expert witness community and the wider justice system. In this update, we discuss policy developments and our advocacy work over the last few months.   

From 1 January 2026, the Civil Procedure Rule Committee will be piloting access to public domain documents in the Commercial Court and London Circuit Commercial Court of the King’s Bench Division and the Financial List (Commercial Court and Chancery Division).
