The detail of this judgment is for experts who conduct capacity assessments. Two points arise of more general interest.

First, the expert, who had been involved in the case for six years, changed her opinion. In the language of the court it was a 180^o degree change. The court thought that this called for a greater discussion in the analysis section of the report. This seems to have been that section of the report for which experts use the heading ‘Facts and assumed facts’ or ‘Factual analysis’. Second, the expert suggested that the issues, or some of the issues, in the case could be resolved by invoking the inherent jurisdiction of the court. But there had been no application for the exercise of the court's inherent jurisdiction, it was not referred to in the letter of instruction, and it might not – as a matter of law – have been available. This is a good example of the advice to experts to leave the law to the lawyers.  

Calderdale Metropolitan Borough Council v LS [2025] EWCOP 10 (T3)

While there are many respectable and legitimate expert witness agencies who provide brilliant support to the expert witnesses who work with them, the EWI has had continuing reports of the activities of some unethical agencies who prey upon experts who do not have a good understanding of expert witness work or who may be vulnerable to such approaches for other reasons. We do not want any expert to fall victim to an unscrupulous agency, so we have prepared a short guide setting out the red flags to watch out for in the approach of an unethical agency and, conversely, the sorts of positive signs to expect from a respectable and legitimate agency, including a quick checklist to complete. 

This is an important judgment for experts who prepare personal injury reports in the Republic of Ireland but also for all experts, in all of the jurisdictions in the British Isles, for its description of the judicial analysis of expert evidence. It deals with procedure in Ireland for the instruction of specialist medical experts through plaintiffs’ general practitioners.

Hon Mr Justice Trower provides invaluable guidance for Expert Witnesses at the 2024 the Sir Michael Davies lecture.

Earlier this year, we asked our members about the single biggest change they’ve seen since they started practicing as an Expert Witness. With members from numerous disciplines who’ve been practicing from 40 years to 4 months, we expected a wide variety of insights, and we weren’t disappointed.

Mr X accepted instructions to provide advice in property valuation despite not being an expert in that field. 

Kallakis v Kallakis [2023] EWHC 2148 (Comm) 

It is common in my practice that I have to provide dates of availability for Court listings. I plan my leave around 12-18 months in advance so that I can book trips etc but also leave adequate space available for Court listings. I am currently dealing with an instructing solicitor who is insisting that holidays / leave are not a reason to be unavailable for Court. They have quoted the case of Matthews v Tarmac.

The judge considered, but did not reach a conclusion on, whether a party's communications with their expert before a joint meeting of experts should be disclosed.
