I understand that my overriding duty is to the court and I have complied with that duty. I am aware of the requirements of CPR Part 35, its practice direction and the CJC Guidance for the instruction of experts in civil claims.
I confirm that I have made clear which facts and matters referred to in this report are within my own knowledge and which are not. Those that are within my own knowledge I confirm to be true. The opinions I have expressed represent my true and complete professional opinions on the matters to which they refer.
I understand that proceedings for contempt of court may be brought against anyone who makes, or causes to be made, a false statement in a document verified by a statement of truth without an honest belief in its truth.
As of November 2016, the CrimPR provides specific guidance in its Practice Direction (updated October 2023) on what should be included, split into a set of declarations and a statement of truth. Unlike the civil arena, however, the wording is not mandatory, but it should be in the following terms, or in terms substantially the same.
1. I understand that my duty is to help the court to achieve the overriding objective by giving independent assistance by way of objective, unbiased opinion on matters within my expertise, both in preparing reports and giving oral evidence. I understand that this duty overrides any obligation to the party by whom I am engaged or the person who has paid or is liable to pay me. I confirm that I have complied with and will continue to comply with that duty.
2. I confirm that I have not entered into any arrangement where the amount or payment of my fees is in any way dependent on the outcome of the case.
3. I know of no conflict of interest of any kind, other than any which I have disclosed in my report.
4. I do not consider that any interest which I have disclosed affects my suitability as an expert witness on any issues on which I have given evidence.
5. I will advise the party by whom I am instructed if, between the date of my report and the trial, there is any change in circumstances which affect my answers to points 3 and 4 above.
6. I have shown the sources of all information I have used.
7. I have exercised reasonable care and skill in order to be accurate and complete in preparing this report.
8. I have endeavoured to include in my report those matters, of which I have knowledge or of which I have been made aware, that might adversely affect the validity of my opinion. I have clearly stated any qualifications to my opinion.
9. I have not, without forming an independent view, included or excluded anything which has been suggested to me by others including my instructing lawyers.
10. I will notify those instructing me immediately and confirm in writing if for any reason my existing report requires any correction or qualification.
11. I understand that:
(a) my report will form the evidence to be given under oath or affirmation;
(b) the court may at any stage direct a discussion to take place between experts;
(c) the court may direct that, following a discussion between the experts, a statement should be prepared showing those issues which are agreed and those issues which are not agreed, together with the reasons;
(d) I may be required to attend court to be cross-examined on my report by a cross-examiner assisted by an expert.
(e) I am likely to be the subject of public adverse criticism by the judge if the Court concludes that I have not taken reasonable care in trying to meet the standards set out above.
12. I have read Part 19 of the Criminal Procedure Rules and I have complied with its requirements.
13. I confirm that I have complied with the code of practice or conduct for experts of my discipline, namely [identify the code], in all respects save as identified in [schedule][annexe][x] to this report. That [schedule][annexe] gives details of the action taken to mitigate any risk of error that might arise as a result.
14. [For Experts instructed by the Prosecution only]
I confirm that I have read the CPS Guidance for Experts on Disclosure, Unused Material and Case Management which details my role and documents my responsibilities, in relation to revelation as an expert witness. I have followed the guidance and recognise the continuing nature of my responsibilities of disclosure. In accordance with my duties of disclosure, as documented in the guidance booklet, I confirm that:
(a) I have complied with my duties to record, retain and reveal material in accordance with the Criminal Procedure and Investigations Act 1996, as amended;
(b) I have compiled an Index of all material. I will ensure that the Index is updated in the event I am provided with or generate additional material;
(c) in the event my opinion changes on any material issue, I will inform the investigating officer, as soon as reasonably practicable and give reasons.
