EXPERT WATCH 42: THIS IS NOT EXPERT EVIDENCE – BUT A SIMPLE STEP UP FROM “NUMBER CRUNCHING” : ALSO OPINION EVIDENCE SHOULD BE DISTINGUISHED FROM FACTUAL EVIDENCE
Here we have a case where the judge found evidence provided by experts to be of “assistance” but where he was clear in his view that the information put forward was not expert evidence. The evidence was “simply a kind…
EXPERT WATCH 41: THE COURT OF APPEAL REFUSES TO OVERTURN A DECISION WHERE THE “WRONG” TYPE OF JOINT EXPERT WAS INSTRUCTED
This is an unusual case where, after the event, a party to the litigation argued that the court had relied on the “wrong” type of expert evidence. An educational psychologist had been instructed as a joint expert whereas what was…
EXPERT WATCH 40: THE TRIAL JUDGE DID NOT ACCEPT THE EVIDENCE OF THE JOINTLY INSTRUCTED WITNESS: “THE DUTY OF THE COURT IS TO APPLY THE BURDEN OF PROOF AND TO FIND THE FACTS HAVING REGARD TO ALL THE EVIDENCE IN THE CASE…”
This is a case where the judge did not accept the views of a jointly instructed expert as to the authenticity of a document that was central to the case. The expert did not have access to all the relevant…
AVOIDING THE PITFALLS WITH EXPERT EVIDENCE: WEBINAR 20th MARCH 2026: THE EXPERTS REPORT WAS “ALMOST WORSE THAN USELESS…”
We have seen some graphic examples in the past few weeks of a court robustly rejecting expert evidence adduced on behalf of a claimant. This webinar examines why expert evidence is not accepted, limited, or even wholly rejected at trial….
EXPERT WATCH 39: WHEN THE HOME SECRETARY DID NOT CHALLENGE EXPERT EVIDENCE SHE CANNOT BE THAT SURPRISED WHEN THE COURT ACCEPTS IT
We are looking at another case where a party failed to challenge expert evidence. The Court of Appeal was clear in its view that if fault lay anywhere it was with the appellant’s failure to challenge the expert evidence that…
EXPERT WATCH 39: BOTH EXPERTS “ACTED AS SURROGATE ADVOCATES ON BEHALF OF THEIR INSTRUCTING PARTY”: MORE LESSONS TO BE LEARNT…
We have another High Court decision where the judge was highly critical of the approach of each expert. The judge found that each took on the role of advocate rather than expert. The criticisms are stark “they were similar in…
EXPERT WATCH 37: THE COURT SHOULD MAKE FINDINGS OF FACT FIRST AND NOT ABDICATE THIS TASK TO AN EXPERT: A FIRST INSTANCE DECISION WITH A “FUNDAMENTAL FLAW”
We are looking at a family law case which considers several significant aspects of expert evidence. Firstly it makes clear that it is not for an expert to make findings of fact. Further a judge cannot simply abdicate they key…
EXPERT WATCH 35: CLAIMANT REFUSED PERMISSION TO ADDUCE A SUPPLEMENTARY REPORT AFTER THE TRIAL HAD ENDED
There are many (if not all) working advocates who have thought, after a hearing is over, “I could have said that”. The same may well be true of experts. Here we have an attempt to introduce new material in a…
THROWBACK FRIDAY: “EXPERTS: THE JOINT REPORT AND THOSE TROUBLESOME “AGENDAS”: FEBRUARY 2018

EXPERT WATCH 34: THE COURT REFUSES TO REPLACE A JOINTLY INSTRUCTED EXPERT BUT ALLOWS SOME OF THE PARTIES TO INSTRUCT THEIR OWN EXPERT
When it is appropriate for a court to replace a jointly instructed expert? That issue was considered in this case. The judge rejected the allegations made about the jointly instructed expert, however given that expert evidence was central to the…

EXPERT WATCH 32: A REVIEW OF THE CASE LAW AS TO THE INDEPENDENCE (OR OTHERWISE) OF EXPERT WITNESSES
We are looking again at a case looked at yesterday. This is because the judgment contained a useful summary of many leading cases relating to the question of expert bias, or apparent bias. “It is always desirable that an expert…
EXPERT WATCH 31: A PARTY WAS NOT ALLOWED TO RELY ON THE EXPERT EVIDENCE OF SOMEONE WHO WAS CONFLICTED: THE EXPERT CANNOT “MARK THEIR OWN HOMEWORK”
This is an interesting example of a judge refusing a party permission to rely on an expert witness because they were conflicted. They had been involved in the issues previously and could not give independent or disinterested advice. “Ms…
EXPERT WATCH 29: THE JUDGE IS WARY OF A CLINICAL EXPERT WHO IS “HEAVILY INVOLVED IN THE BUSINESS OF LITIGATION”
There have been a number of cases in recent years where judges have been wary (sometimes highly sceptical) of expert witnesses who make their living solely from being involved in litigation. We have another example here. There is no indication…
REVIEW OF THE YEAR 6: EXPERTS IN THE COURTS IN 2025: CASES ON THIS BLOG
I am surprised (but perhaps shouldn’t be) at the sheer number of cases involving experts that the blog has covered this year. In July I started the “Expert Watch” series to focus on cases about the conduct of experts and…
COST BITES 317: ANOTHER ROUND IN THE MEDICAL AGENCY FEES/BREAKDOWN BATTLE: THE AGENCY MUST PROVIDE A BREAKDOWN

EXPERT WATCH 28: I CAN’T GIVE PERMISSION FOR AN EXPERT BECAUSE THIS IS SIMPLY NOT EXPERT EVIDENCE: FORENSIC ACCOUNTANT’S REPORT DOESN’T GET THE CREDIT IT DESERVES…
The judge here held that the report prepared by a forensic accountant was not, in fact, an expert’s report. The report well be helpful, but its contents did not come within the meaning of “expert evidence”. Further insofar as the…
THE CURRENT IMPORTANCE OF PLEADINGS 42: THE SIGNIFICANT DIFFERENCE BETWEEN A “NON-ADMISSION” AND A “DENIAL”: DEFENDANT REFUSED PERMISSION TO RELY ON EXPERT EVIDENCE BECAUSE OF THE WAY IN WHICH THE CASE WAS PLEADED
This is the first of two interesting cases today that have been sent in by readers. I am grateful to Rebecca McVety of the Dental Law Partnership for sending me this judgment which deals with pleadings, in particular the very…
EXPERT WATCH 27 : WHAT DOES THE COURT DO WHEN AN EXPERT’S EXAMINATION HAS BEEN COVERTLY RECORDED? “I HOPE HE WILL NEVER DO IT AGAIN…”
Covert recordings, of one type or another, are featuring heavily on this blog today. Here we consider a case where a claimant secretly recorded her examination by an expert instructed by the defendant. The claimant then applied to admit the…
EXPERT WATCH 26: JUDGE’S DECISION NOT TO ADMIT EXPERT EVIDENCE UPHELD BY THE COURT OF APPEAL: “IT IS NOT CLEAR TO ME WHAT VALUE IT WOULD ADD TO THE CASE”
It is rare to see an appeal where a decision about whether to admit expert evidence is considered. In this case the Court of Appeal considered the judge’s decision not to admit a report. Both parties agreed that the report…
EXPERT WATCH 25: EXPERT IN ELECTION CASE FAILS TO GET THE JUDGES’ VOTE: THE EXPERT SHOULD BE SENT (AND CONSIDER) CONTRADICTING EVIDENCE
There are not many cases where issues relating to expert evidence are considered in an Election Court. We have such a case here. The Court allowed expert evidence to be admitted. However it was unable to give any weight to…

EXPERT WATCH 24: WHEN AN EXPERT IN A CLINICAL NEGLIGENCE DOES NOT UNDERSTAND THE “BOLAM” TEST (WHICH IS REFERRED TO IN THEIR OWN REPORT)THIS IS NOT DETERMINATIVE: BUT IT DOESN’T HELP
This is not the first time we have looked at a case where an expert in a clinical negligence has revealed in cross-examination that they do no really understand the “Bolam” test for negligence. We look at such a case…
EXPERT WATCH 23: NOW THINGS GET EVEN MORE REMARKABLE: EXPERT WRITES TO THE COURT TO SAY “MY EVIDENCE WAS WRONG”: REGULATORY BODY THINKS THE REPORT WAS VERY WRONG…
The previous post recorded how it is still possible to be surprised by what goes on in litigation. We see that again here, but to a greater extent. After a trial and a judgment was given an expert wrote to…
EXPERT WATCH 22: JUST WHEN YOU THINK YOU MAY HAVE SEEN IT ALL: THE CLIENT (BASICALLY) DRAFTS THE JOINT STATEMENT: THE JUDGE THINKS THEY MAY HAVE PLAYED A LARGE PART IN THE DRAFTING OF THE REPORT ITSELF…
No matter how long, and how much, you write about civil procedure cases can still come along which surprise – if not astonish. We have such a case here. The judge found that, essentially, it was the client who played…
MEMBER NEWS: UPDATE ON THE CIVIL LITIGATION BRIEF WEBINAR SERIES: THIS SITE WILL BE OFFLINE FOR AN HOUR ON THE 29th OCTOBER

EXPERT WATCH 21: THE EXPERT WHO FAILED TO CONSIDER NEW EVIDENCE IN SUFFICIENT DETAIL AND “WHO WAS NOT PARTICULARLY OPEN TO RECONSIDERING HIS OPINION”
Here we look at a judgment about medical evidence in a personal injury action. The issue was one of causation – whether an earlier injury to the claimant’s leg “caused” a later decision to have that leg amputated. The critique…
EXPERT WATCH 20: THE APPROPRIATE APPROACH WHEN THE PARTIES CANNOT AGREE INSTRUCTIONS TO A SINGLE JOINT EXPERT
Here we are looking at a case where there was an issue as to the instructions given, or to be given, to a single joint expert. The judge set out the basis upon which such experts are instructed and the…

Here we look at a claimant’s applications under CPR 31.14(1) and 35.10 to have sight of a draft expert report that the defendant had referred to in a defence and in the report of another expert. The judgment contains a…
EXPERT WATCH 17: A DETAILED CONSIDERATION BY THE HIGH COURT OF WHEN EXPERT EVIDENCE IS PERMITTED OR “REASONABLY REQUIRED”: COMPLIANCE WITH THE RULES IS VERY IMPORTANT HERE

EXPERT WATCH 16: IS PART 35 PERMISSION NEEDED WHEN A DOCTOR GIVES OPINION EVIDENCE AS TO A PARTY’S ABILITY TO PARTICIPATE IN LITIGATION?
Here we look at a case where a party was seeking a stay of litigation on medical grounds. Medical evidence was provided which supported the litigant’s stance. The claimant took objection to the report as it contained “opinion” and the…
EXPERT WATCH 15: A CHANGE OF APPROACH BY EXPERTS (WHICH FAVOURED THE SIDE THAT INSTRUCTED THEM) HAS TO BE LOOKED AT “PARTICULARLY CRITICALLY” BY THE COURT
We are looking at a case where expert evidence was of considerable importance. The claimants had already had permission to rely upon one of their experts disallowed because of issues relating to conduct. Here we have an example of the…
EXPERT WATCH 14: THERE WERE “TOO MANY IMPONDERABLES” TO FORM A VIEW THAT THE INJURIES WOULD HAVE BEEN REDUCED IF A CAR HAD BEEN DRIVEN AT A LOWER SPEED
The judge in this case considered whether the medical evidence established that driving at a lower speed would have “significantly reduced” the injuries that the claimant suffered. This is often a difficult matter to prove. (The evidence on whether…
EXPERT WATCH 13: “IT SUGGESTS THE WITNESS WAS SEEKING TO BUILD A CASE FOR THE CLAIMANTS RATHER THAN INDEPENDENTLY ANALYSE THE EVIDENCE IN REACHING HIS OPINION”: THE JUDGE FINDS THIS TROUBLING
Here we are looking a judicial observations about the role of forensic reconstruction experts. There are telling comments on the reasons the judge preferred one expert over another. Again it comes down to a simple failure to consider and apply…
EXPERT WATCH 13: WHEN THE CLAIMANT ATTEMPTED TO INTRODUCE A NEW CASE DURING CROSS-EXAMINATION OF THE DEFENDANTS’ EXPERT (HOW DO WE THINK THIS WENT?)
We are looking at a case where the claimant’s expert, belatedly, accepted that the reports he was relying on were unreliable. The claimant then attempted to introduce new matters and evidence to bolster an alternative case. The judge rejected that…
THREE WEBINARS ON EXPERTS: THE JOINT EXPERT AND MEETING OF EXPERTS; PART 35 QUESTIONS AND EXPERTS IN THE COURTS IN 2025

EXPERT WATCH 12: “THE EXPERT EVIDENCE FOR BOTH SIDES HAD PROBLEMS”: THE JUDGE PREFERS THE DEFENDANT’S EXPERT

EXPERT WATCH 11: EXPERT ASSERTS THAT THE CLAIMANT WAS MALINGERING BUT WOULDN’T TELL THE COURT ABOUT THE DETAILS OF THE TESTS THAT LED TO THAT CONCLUSION
We have seen some unusual conduct of experts on this site. However the case we look at today has elements that we have not looked at before. An expert carried out tests on the claimant and, as a result of…
EXPERT WATCH 10: CLAIMANT UNSUCCESSFUL ON APPEAL IN ATTEMPTING TO OVERTURN THE TRIAL JUDGE’S PREFERENCE FOR THE DEFENDANT’S EXPERTS: “THE IRREDUCIBLE FACT IS IS THAT THE JUDGE ACCEPTED THE EXPERT EVIDENCE OF THE RESPONDENT’S KEY WITNESS AND PREFERRED TO OVER THE EVIDENCE OF THE APPELLANT’S KEY EXPERT WITNESS”
There are relatively few cases where a party appeals on the basis that trial judge was wrong to accept the evidence of one party’s expert witness in preference to the other. There are even fewer cases where such an appeal…
EXPERT WATCH 8: “SCIENCE DOES NOT CHANGE” : EVIDENCE THAT WAS “UNIMPRESSIVE IN PARTS AND OF LITTLE ASSISTANCE TO THE COURT”
To end the week I am looking at another decision about expert witnesses (it has been a theme this week). This time we are looking at accident reconstruction experts. One expert was found wanting, the judge favoured the other. The…
EXPERT WATCH 7: “THIS CASE IS NOT SHORT OF ADVOCATES”: AN EXPERT REPORTING FOR THE CLAIMANT SHOULD NOT HAVE BEEN ONE OF THEM: FURTHER THEY SHOULD HAVE DISCLOSED THAT THEY HAD “COPIED” THEIR REPORT
Yesterday I imposed a 24 hour respite on this series “unless something really interesting comes up”. I have broken that promise, it lasted 22 hours. However the cases on experts keep coming in and, I think, readers need to know…
EXPERT WATCH 5: AN EXPERT SHOULD DISCLOSE PREVIOUS CRITICISMS MADE BY JUDGES: PARTICULARLY WHEN THEY HAVE BEEN WARNED ABOUT THIS BEFORE…
We have seen a trend in a number of recent cases of advocates cross examining experts and referring to judicial criticism made in previous cases that experts have been involved in. The judgment here goes one further and indicates that…
EXPERT WATCH 4: THE EXPERT SHOULD INFORM THE COURT IF MEMBERSHIP OF A PROFESSIONAL ORGANISATION HAD CEASED, PARTICULARLY IF THIS IS LINKED TO DISCIPLINARY PROCEEDINGS AGAINST THEM
We are returning (and not for the last time) to a recent decision where the court considered the expert evidence in detail. Here we look at the judgment in relation to an expert who failed, until prompted, to inform the…
EXPERT WATCH 3: EVIDENCE FROM EXPERTS ON FOREIGN LAW: SOME OF THE EXPERTS FOUND WANTING

EXPERT WATCH 1: THE DUTY TO STATE THE SOURCES OF THE EXPERT’S INFORMATION
This is the start of a series examining cases where expert evidence is considered by the courts. As matters stand there are already dozens of posts on this site where the conduct of experts has been considered (and often criticised)…
WHEN A PARTY RELIES ON “NON PART 35 COMPLIANT” EXPERT REPORTS: THIS IS HARDLY LIKELY TO CARRY MUCH WEIGHT…
The first question the lawyer must ask when being presented with a report for use in proceeding is – is this report CPR 35 compliant? If it is not then it may have little, if any value. There is a…
IF A CLAIMANT ISSUES AND LITIGATES WHEN THEY DO NOT HAVE CAPACITY – ARE THEY LIABLE FOR THE COSTS INCURRED? COURT OF APPEAL SCRUTINISES EXPERT EVIDENCE AND FINDS IT WANTING
Yesterday we looked at issues relating to the capacity of a solicitor’s client and their consequent liability to pay costs. Today we look at a case about inter partes costs. If a claimant brings proceedings but does not, in fact,…
WHEN A PARTY MAKES A SECOND APPLICATION TO RELY ON EXPERT WITNESS HOW SHOULD THE COURT RESPOND? THE SAGA CONTINUED
We are looking at this case for the third time. There were issues in relation to witness evidence and expert evidence. The problems continued after trial when the judge realised that neither party had addressed her on a mandatory requirement…
IF YOU ARE GOING TO CRITICISE AN EXPERT THIS MUCH YOU SHOULD HAVE RAISED IT AT THE CASE MANAGEMENT HEARING: HIGH COURT REJECTS EACH PARTY’S ATTACKS ON OPPONENT’S EXPERTS
We have seen plenty of cases where the courts have not been slow in their criticism of expert witnesses. Here we have a different situation where the judge was critical of the attacks, by each party, on the credibility of…
HOW FAR IS A TRIAL JUDGE BOUND TO FOLLOW THE VIEWS OF A JOINTLY INSTRUCTED EXPERT? WELL – READ THIS FOR SOME TRENCHANT VIEWS…
When the parties jointly instruct an expert how far is the judge “bound” by the views that the expert reaches? This is an issue we are looking at for the second time within 6 days. We have an interesting consideration…
