Expert witness reports, Exeter. Our client pays the bill; the court gets the loyalty.

A report prepared by an expert is not your position in a case with additional support. The civil rules provide that the expert has an overriding duty to the court, as opposed to the party who instructs or pays them, and therefore any report drafted any other way will be of no value when it gets challenged. All reports generated by this laboratory begin with that premise.

What a compliant report contains.

The duty clauseIn civil procedure (the rules), experts assist the courts based upon the areas of their expertise, making this responsibility superior to any interest of those who instruct them. This is stated at the beginning of the report and used to judge the validity of the report.
Statements of truth & complianceThe expert confirms what facts are within their own knowledge and true, states that their opinions are complete and honestly held, and that both Part 35 and the associated practice direction have been complied with.
Method and exhibit continuityHow all items arrived, were imaged, hashed and analysed, and where they went throughout, cross-referenced for another expert to follow that same trail of steps again.
Credibility disclosureThe criminal procedure rules have since 2019 required disclosure of everything which could affect the standing of an expert, expressly including their lack of accreditation. Ours leads the report and is not buried in a footnote.

01

Talked through in confidence, quoted in writing Free

When you instruct us on a new matter, we will first hold a confidential conversation about what has occurred, which devices/accounts matter and what the evidence needs to establish. Following this, you will receive a single written quote, fixed prior to any examination commencing, and the initial scope of works does not incur any cost.

02

Everything declared first

Instructions received by us are recorded. The report itself also summarises those instructions. All things which may affect credibility (including that we are an independent laboratory with no accreditation) shall be stated prior to commencing any analysis; not after.

Instructions loggedStatus disclosed up front
03

Assume cross-examination

Each step of analysis shall be performed and documented as though the other side's expert was already reviewing our work, because at some point they will. Findings are not influenced by the party providing instruction.

Court before clientNo edited conclusions
04

Drafted to the rules

The report follows CPR Part 35 or CrimPR Part 19, depending upon which is required by the nature of the case: method of testing, exhibits submitted for testing, the custody chain of exhibits, statements of truth and compliance; plain English conclusions are reported first, then the technical appendices.

Captured, documented, court-ready

You get everything: the report, all of the exhibits and the files behind each exhibit, as well as the hashes, the continuity record and our working notes. If at some time in the future a tribunal or another expert wishes to verify anything, they will be able to follow the entire chain of evidence from start to finish.

Rules the bench works by

  • The overriding duty is the whole point, which means that under the rules the obligation to help the court has precedence over every obligation to the instructing or paying party. A report that does not recognise this is essentially useless.
  • Criminal reports must include data about the reliability of the author (the expert), including qualifications, experience and other information which will allow the court to assess the value and quality of the expert's opinion.
  • Appointing a single joint expert for both parties creates a new dynamic: one person working for two different parties, with no 'home' party. We accept these types of assignments.
  • Clarity is a compliance issue: a report that cannot be followed by the tribunal has failed in its only purpose, no matter how rigorous the appendices are.

Check this one thing before hiring any expert: since April 2019, the criminal practice directions require disclosure of all information that could undermine the reliability of the expert. Missing accreditation is specifically included in this. If the expert withholds that information, they may damage your case. We put ours on page one.

The Part 35 report that ended a Devon dispute

We had two firms involved. We had one missing folder. We had two very different versions of what happened. The image did not support either version outright, and the timeline made that as clear as day. Settlement occurred within a month after service of the report.

Dealt with after exchangeCPR 35 compliant

Before it leaves your hands.

Do

  • Say it at the beginning if there may be litigation (the methodology changes)
  • Get us your letter of instruction as soon as possible
  • Send over to us whatever questions the other side's expert is asking
  • Give us enough time to produce quality work; we do not create rigorous reports in one night

Steer clear

  • Encourage us to conclude something that the evidence cannot support
  • Re-write our conclusions; dispute them based upon your own evidence if you disagree
  • Require a compliant report from us only a week prior to when it will be needed
  • Seek out an 'expert' who is likely to provide an opinion favourable to your position; the courts see right through this type of tactic

Asked in private, answered plainly.

Forensic report or expert witness report — what separates the two?

The findings report will describe what was found and how it was done. The report which goes to court has a greater standing than the findings report; it sets out the overriding duty of the expert to the court, contains statements of truth and compliance declarations, includes an overview of the instructions, provides all details about the methodology in full and the custody chain, and makes disclosure of any material which may have bearing on credibility, at the commencement.

Who does an expert witness act for?

Ultimately, the formal obligations of an expert to the court take precedence over their obligations to the person who has instructed them or paid them. It is this that provides weight and substance to a compliant report.

Will you act as a single joint expert?

We will. When the court decides there should just be a single joint expert, then each side gets the same version of our report, and that tends to focus their minds.

Will missing accreditation count against us in court?

It has to be disclosed, so we do disclose it, and then the court compares it with the method, and the method is what makes a report. Overclaiming is how experts lose credibility; we claim only what we can show.

Evidence fades fast. Don't hang about.

When recorders overwrite on a loop, all recorded evidence will weaken and time limitations expire, so open your case now. The first review is completely free and confidential.
