Foreword

[By DPP (CPS) & Maria Wallis (ACPO) on behalf of Prosecution Team.]

The scheme set out in the Criminal Procedure and Investigation Act 1996 (the Act) as amended by the Criminal Justice Act 2003 and the revised Code of Practice issued under it (the Code) is designed to ensure that there is a fair system for the disclosure of unused material, which assists the defence in the timely preparation and presentation of its case, does not overburden the parties and enables the court to focus on all the important issues in the trial.

The instructions contained in this booklet are designed to provide a practical guide to disclosure obligations for expert witnesses instructed by the Prosecution Team. When properly applied, these instructions will assist expert witnesses, investigators and prosecutors to perform their disclosure duties effectively fairly and justly, which is vitally important to the integrity of the criminal justice system.

The considered application of this guidance and appropriate management of the materials within the investigation by experts will enhance their credibility and promote confidence in the role of the expert witness.

This booklet reflects the commitment of the Prosecution Team to work alongside expert witnesses and other agencies to ensure that disclosure is complied with fairly and properly.

  1. Introduction
  2. You are instructed by the Prosecution Team, which comprises the Police and Crown Prosecution Service, as an expert in this investigation. It is important that you understand the obligations placed upon you by this status. As an expert witness you have an overriding duty to assist the court and, in this respect, your duty is to the court and not to the Prosecuting Team instructing you. This will include obligations relating to disclosure.

    The obligations which apply to you as an expert are to assist in ensuring that the Prosecution Team can comply fully with their statutory disclosure obligations. These obligations take precedence over any internal codes of practice or other standards set by any professional organisations to which you may belong. Your obligations are set out in part 3 of this booklet, but can be summarised in the key actions of retain, record and reveal.

    A failure to comply with the guidelines in this booklet may have a number of adverse consequences which could include:

    • A prosecution being halted or delayed;
    • The appellate courts finding that a conviction is unsafe;
    • The tribunal making an adverse judicial comment about you as an expert. Such an adverse judicial comment could seriously undermine your credibility as an expert and consequently your fitness to be instructed in future cases;
    • Professional embarrassment, including possible action by a professional body, loss of accreditation and the potential for civil action by an accused.

    Conversely, your credibility as an expert will be enhanced by the considered application of this guidance and your appropriate management of the materials within the investigation.

    An expert employed by the police is not a third party and is already required to comply with the Criminal Procedure and Investigations Act and should comply with the detailed guidance in the Disclosure Manual (see below).

  3. Disclosure obligations under the criminal law
    1. Aims of disclosure
    2. The regime for disclosure is set out in the Act and the Code, issued under it. This is designed to ensure that there is a fair system for the disclosure of unused material which assists the defence in the timely preparation of its case, does not overburden the parties and enables the court to focus on all the important issues in the trial.

      Top of page

    3. The meaning of unused material
    4. During the course of any investigation material is generated. Some of it is used as evidence and other material is not used. The material that is not used as evidence is known as unused material, to which the disclosure regime applies.

      Unused material is material that is relevant to the investigation but which does not actually form part of the case for the prosecution against the accused. Even though the material may not be used as evidence, it is important that for the purposes of disclosure this material is retained.

      It is not for you to determine whether the material generated in the course of an investigation is relevant to the investigation.

    5. The Disclosure Manual/Attorney General's Guidelines
    6. The Disclosure Manual (The Manual) contains the operational instructions on disclosure which have been agreed by the CPS and the Association of Chief Police Officers. It explains how the Prosecution Team have agreed to fulfil their duties to disclose unused material to the defence. These duties arise under statute and at common law.

      The Manual contains practical guidance to the police and CPS practitioners which supplements the framework of the Act, the Code and the Attorney General's Guidelines. The Manual is available on this website.

      The Attorney General's Guidelines build on existing law to help ensure that the legislation is operated consistently and fairly by the Prosecution Team. They can be found at: http://www.lslo.gov.uk/guidelines.htm.

  4. Discharging your obligations
  5. There are three key obligations arising for you, as an expert, as the investigation progresses. Your understanding of these obligations and delivering them is the key to you adequately fulfilling your disclosure obligations. The relevant steps are to retain, to record, and to reveal. The flowchart attached at appendix D to this guidance illustrates this process.

    1. Retain
      1. What to retain
      2. You should retain everything, including physical, written and electronically captured material, until otherwise instructed and the investigator has indicated the appropriate action to take.

        Top of page

      3. How long to retain
      4. The period of time for which materials are required to be retained will vary from case to case and will depend on a number of factors. Examples include the nature of the offence; the stage and status of any legal proceedings; whether the case is of special interest. It must also be remembered that the retention requirement may alter as a result of a change of circumstances during the course of the investigation.

        You should, therefore, obtain advice from the investigator for the retention period hat applies to this particular investigation and always before contemplating destruction of any material.

    2. Record
      1. When to record
      2. The requirement for you to commence making records begins at the time you receive instructions and continues for the whole of the time you are involved.

        Circumstances may exist, however, where practitioners should commence making records, in accordance with this guidance, prior to any instructions from the police. Examples of this would be:

        • where as a pathologist the outcome of a 'routine' post-mortem suggests to you that death has been caused under suspicious circumstances;
        • as a medical practitioner you find injuries that are not consistent with the alleged cause;
        • as a fire scene examiner you believe a fire to have been started deliberately.

        In all these examples the criminal investigation will start after the practitioner's original involvement but the results of the previous examinations will almost certainly be material to any investigation and subsequent prosecution. The list is not intended to be exhaustive.

        This practitioner could be you. If you have any doubts start recording.

        Top of page

      3. What to record
      4. You should keep records of all the work you have carried out and any findings you make in relation to the investigation. The guidance provided below reflects best practice and your records, as a minimum, should contain information relating to:

        • the collection and movement of items, including
          • the date on which you take or receive material (physical items and information) and the date of subsequent movement of the material to another party
          • from who or where and to whom or where material is moved
          • the means by which you receive or pass material from/to another party
        • the examination of materials
          • your notes, and those of any assistant should be signed, dated, attributable to the individual and produced contemporaneously, whenever practicable
          • the notes should be sufficiently detailed and expressed in such a manner that another expert, in your field, can follow the nature of the work undertaken, any assumptions made and the inferences you have drawn from the work
        • verbal and other communications
          • you should keep your own notes of all meetings you attend
          • you should keep your own notes of telephone conversations and it is important that points of agreement, or disagreement and agreed actions are recorded
          • you should ensure that a record of all e-mails and other electronic transmissions (e.g. images), sent or received, is kept
          • you should keep clear notes of any witness accounts or explanations that you have been provided with, or any other information received

        Top of page

      5. How to record
      6. The media you use for making your records should be capable of meeting all the requirements given above, be durable and provide a means of retrieval.

        Your notes, in whatever form, should also be structured in a manner that facilitates review. Any updates, alterations or comments should be clear. It is important that your notes are clear and comprehensive. This will allow another person who may subsequently review them to have a full understanding of the position at any given time.

        Top of page

    3. Reveal
      1. What to reveal
      2. You are required to reveal everything you have recorded.

        It is a necessary and important part of your disclosure obligations to make the Prosecution Team aware of all the material you have in your possession in relation to the investigation. This will then enable them to make informed decisions, as to what material is relevant, and then what material satisfies the disclosure test.

        Top of page

      3. How to reveal
      4. There are three ways in which you will reveal material to the Prosecution Team.

        The Report

        Your report(s) should contain information relating to the following:

        • details of your qualifications, experience or accreditation relevant to the work performed
        • the range and extent of your expertise
        • details of any information upon which you have relied in arriving at your opinion
        • details of any statements of fact upon which you have relied in reaching your opinion
        • clarification of which of the facts are within your own knowledge
        • information relating to who has carried out measurements, examinations, tests etc and if under your supervision
        • your opinion(s) and a justification for these
        • where you have provided qualified opinions details of the qualifications
        • a summary of all your conclusions
        Statements

        In addition to all of the above you may be required to make a formal statement. The statement should contain all of the above and the following:

        • the declaration which confirms that you understand your duty to the court in respect of disclosure
        • an acknowledgement that you will inform all parties and, where appropriate the court, in the event that your view changes on any material issue.

        When compiling your report/statement you should ensure that due regard is given to any information that points away from, as well as towards, the defendant(s).

        You must not give expert opinion beyond your area of expertise.

        The Index of Unused Material

        In order to reveal material to the Prosecution Team, it is necessary that you to complete an index of unused material, (the Index) describing all the unused material in your possession. All the material not identified in your report/statement should be placed on the Index.

        The Index is designed to enable you to provide to the Prosecution Team a description of all the unused material in your possession in a structured, comprehensive and informative manner.

        An example of a specimen Index is given in Appendix A. You will need to tailor the descriptions of the materials to meet your specific case requirements. Your descriptions, however, must be full enough for others to clearly understand the nature of the material. Please note that this example is neither exhaustive nor exclusive.

        You should not attempt to make judgements on the significance of material when producing the Index. Where you believe material may be confidential or sensitive, for example for commercial reasons, then this should be placed on a separate schedule and discussed with the Prosecution Team.

        Revelation to the Prosecution Team does not necessarily mean disclosure to the defence.

        Top of page

  6. Declaration of Understanding
  7. You are required to confirm your understanding of your disclosure obligations to the court, as set out in the guidance given in this booklet, by signing a declaration (the Declaration) of understanding. This Declaration will be incorporated into your statement and the required form of words is given in Appendix B.

    An expert employed by the police is obliged to comply with the disclosure regime as set out in the Act. All non-police experts will be expected to sign the Declaration that they have done so.

  8. The Experts Self-Certificate
  9. Upon receipt of instructions you are required to complete a self-certificate (the Certificate) in every case that you are instructed as an expert witness for the Prosecution. The completed Certificate should be sent to the disclosure officer or investigating officer. The Certificate can be found at Appendix C.
