In the 12th episode of the Expert Matters Podcast, we discuss Expert Discussions and Joint Statements. Joint Statements are critical documents in any proceeding, so join us as we discuss how to do them well and avoid the common pitfalls, look at the EWI's recently refreshed guidance, and hear top tips from Beth Rigby and Jessica Thurston, who present the EWI webinar on Expert Discussions and Joint Statements. And as usual, we begin with our segment on 'What's going on at EWI?' and end with 'Newsreel', a quick fire discussion of the key things you need to know this month. 

The claimants, who carried on a business breeding falcons, made allegations of harassment and nuisance against their neighbour, who operated a small farm neighbouring their property. While the judge accepted some of the claimants’ criticisms of one of the defendants’ experts, he also noted that the claimants could not complain about the consequences of their putting in new evidence that was not in accordance with the timetable laid down at the CCMC.

Personal injury claims are being brought by approximately 220 pilots and cabin crew at the High Court in London on the grounds of aerotoxic syndrome (ATS). This group of claimants includes 51 claims which were issued by Thompsons in March 2019 involving pilots and cabin crew working for EasyJet, British Airways, Thomas Cook, Jet2 and Virgin Atlantic. These two claims are not included in these ongoing English collective proceedings. These were claims by two pilots who lost the chance of bringing successful claims as a result of the admitted negligence of a Scottish law practice.

In short, the case illustrates a very common situation in which, on the basis of what is often an appropriately diagnosed psychological condition or mental disorder, it is asserted that a litigant is not capable of participating in legal proceedings. In criminal cases, in relation to the accused, the issue is usually fitness to plead and stand trial. In civil proceedings the issue is litigation capacity. As is often the case, the court’s decision is influenced by how the litigant has functioned in previous cases or earlier in the instant proceedings.

F v W [2024] IEHC 631

The Claimant claimed he had suffered a substantial loss due to the destruction of two consignments of poppy heads by the Defendants. The parties were given permission to rely on the written evidence of expert accountants. The Claimant made an application to the Court for the accountancy expert witnesses to give oral evidence at the trial and an application to adduce evidence prepared by his son.

If, which is not clear, medical evidence that assists in the application of the adult dependent relative provisions as to entrance clearance for dependent adults to enter the UK is usually provided by doctors in the country in which the dependent relatives reside, this judgment may be of little interest to healthcare experts in the UK. However, it makes a very basic point about the format of an expert report and it illustrates how important it is to know and understand the particular test or rule that is applicable.

Ali v Entry Clearance Officer [2024] UKAITUR UI2024000707

This was a significant and well reported patent case which was determined in the Intellectual Property List within the High Court last autumn.   

The technical aspects of the case required significant expert input from the panel involved.  The cross-examinations performed by leading Counsel for the parties were lengthy and complicated.  This led to confusion over what evidence was given when the transcripts were re-visited on subsequent trial days. The case shows how consideration should be given to experts who are being cross-examined so not to overload them with questions and information on the stand.

The Legal Aid Agency ('LAA') have updated their Guidance on the Remuneration of Expert Witnesses.

The aim of the new procedure is to ensure cases are properly pleaded before a trial date is assigned and to facilitate the earlier resolution of clinical negligence actions. This should in turn decrease legal costs.

Experts are advised, if possible, to avoid expressing opinions on the basis of possibility. The usually applicable stand of proof is the civil standard – the balance of probabilities or more probable than not. The criminal standard of proof is beyond reasonable doubt (and not beyond all reasonable [sic] doubt as it is sometimes misquoted). In this case it was submitted that the expert used the terms "possibility", "high possibility" and "extremely high possibility" interchangeably and that this was insufficient to satisfy the criminal standard of proof. However, when the court analysed the expert’s report as a whole, it was clear that a tribunal of fact could safely conclude that the criminal standard of proof was satisfied.
