Reports for court · digital evidence, Plymouth

Expert witness reports, Plymouth. Written for the court (not you), soft spots included.

A report is worth only as much as it can withstand. Someone on the other side has been paid to take it apart. A report written to keep happy those who commissioned it will not last the morning. CPR Part 35 decides this in advance: an expert owes the duty to the court, above client, solicitor and fee. Solicitors and insurers across Plymouth, Devon and Cornwall know this. Our reports start here.

What every court report must contain.

The duty above all othersAccording to CPR Part 35, the expert is there to assist the court, and only on matters within their actual competence. The expert's duty sits above whatever the instructing party hoped to hear. It opens the report. Everything after is measured against it.
The signed declarationsFacts from inside the expert's own knowledge which are confirmed true are kept separate from all else. The report states each opinion included in it is honestly held and that nothing has been withheld. And that the report complies with CPR Part 35 and the practice direction.
The method, in sequenceReceipt, imaging, hash values, examination, and where every exhibit was at any time, recorded closely enough for the opposing examiner to repeat.
What tells against usUnder the criminal rules an expert must declare anything bearing upon their credibility. And CPS guidance treats absent accreditation as one such thing. We include ours in the opening pages rather than hiding it in a footnote.

Five report types, and where each goes.

01

A confidential call first, then a written price Free

Call us and tell us as much or as little as you like. The call costs nothing. It needs to establish what the matter is: what happened, which devices and accounts are involved, and what question the evidence has to answer. That defines the scope. One written figure follows from it, and you get that before anything is opened.

Kept in confidenceA single written figureThe question to be answered
02

Written down at the outset

The letter of instruction is summarised into the report (in our own words). Beside that goes all material touching upon our credibility, beginning here: an independent lab holding no accreditation. Better to have it on page 1 than prised out of somebody standing in a witness box.

03

Aimed at a hostile reader

Every step is done and recorded on the basis of being watched by the opposing examiner for the joint that gives. That is what they are engaged for. None of the conclusions points towards whoever is paying.

04

Built to the correct rules

The forum determines the format. Civil work is prepared in accordance with CPR Part 35 and criminal work under CrimPR Part 19. Both need identical working parts: a written method, the exhibits, an unbroken account of where each went and who had them, and two declarations. Conclusions go first, and the technical detail follows in an annex.

Every exhibit, hash and log

Anything the other side can't check is something to argue over. So we put together a bundle that can be checked: exhibit references, the images each finding was read from, every handover with its date, hash values, and the notes made during the examination. Their own examiner can repeat the work and reach the same result.

Findings, and the exhibits behind themHashes kept, each move recordedAnyone can retrace it

What the work keeps showing

  • The overriding duty determines it: whenever what is needed by the court diverges from what the client wants, the court wins, and a report from someone who did not understand that loses its value before anyone opens it.
  • Criminal work requires reliability material: a bench cannot evaluate an opinion until the qualifications and experience behind it have been laid out.
  • A joint instruction changes the arithmetic: two parties instructing one examiner, and nobody to please. We accept them, and say so early.
  • Clarity counts just as much as rigour: a judge should not be translating it, and where they are, the work below goes down the drain.

One question to ask about any expert you are considering: the Criminal Procedure Rules oblige experts to disclose anything a court might reasonably think would call their credibility into question, and CPS guidance mentions missing accreditation specifically as one such thing. Remain silent and the problem becomes your client's. Ours appears on page 1 of every report leaving this room.

Two Cornwall firms sharing one folder, and a CPR Part 35 report

Two companies shared one folder, and the accounts in it existed in two versions which did not match. Imaging showed editing on both, and the order in which those edits took place settled it. The matter closed inside the month.

Finalised post-exchangeCPR 35 throughout

Before you seal the box.

Get these done

  • Inform us early if this may proceed to court, as it shapes the way we work
  • Let us have the instruction letter early
  • Pass on anything the other side's expert has produced
  • Allow weeks, not days: do not expect things to be completed more quickly by pressuring us

What to avoid

  • Push for a conclusion the evidence cannot carry
  • Rewrite our text — argue with the reasoning instead
  • Expect a Part 35 report to be rushed
  • Shop around for an expert who agrees with you first. It will show.

The questions callers ask most.

What separates a court report from a findings report?

A findings report covers two things: what was there, and how it was located. A court report contains everything contained within the findings report, plus more: the duty the expert owes the court, a summary of your instructions, the methods used to reach a conclusion, the history of exhibits from beginning to end, signed statements of truth and compliance with the rules, and everything which may be raised by the opposing side regarding the expert.

Who is the expert working for?

The court. Who is paying for the services is irrelevant. Whatever obligation is owed to the instructing party is secondary to the obligations owed to the court. This is why the report itself has any worth.

Can you take a single joint instruction?

Yes. One report, one set of conclusions, and both parties receive them simultaneously. No drafts are circulated early, and neither party can alter or amend the language.

Does the missing accreditation weaken it?

As per the rules it has to be declared, so it appears at the top rather than buried in fine print. When examining a report, a court will examine the methodology. The methodology is what gives an expert's opinion its weight. It is here that the bulk of the work occurs. Reports come apart because they have overstepped their bounds, not because of the absence of a certificate.

A report reads better written early than late.

The sooner the material arrives at the bench, the more time there is to detail exactly what it demonstrates, and how it was handled. Begin it here. The first look will cost nothing, and what you share will go no further.
