Preliminary issues

In order for the Inquiry to get to their truth of undercover policing and provide recommendations for the future, it has been necessary to resolve certain preliminary issues.

In coming to his conclusions, the Chairman sought and considered input from multiple stakeholders relevant to the issue in hand.


It is critical that documents held by the Metropolitan Police Service (MPS) that are potentially relevant to the Inquiry are adequately preserved. The Inquiry is working to establish where the MPS holds these documents and understand the steps taken to identify and retain them. The Inquiry has requested and received witness statements as evidence of these steps. Several of these statements, along with their exhibits, can be found here.

On 30 August 2018, the Inquiry invited all core participants and interested parties to share their views on how the evidence hearings should be conducted. The consultation asked five specific questions:

  • how and when evidence should be posted on the Inquiry website
  • how best to facilitate witnesses giving their evidence
  • the level of support that witnesses in the Inquiry would wish to receive when giving evidence, and methods by which this may be provided
  • whether or not providing a small number of rooms for use by attendees other than witnesses would be needed
  • views on live streaming from potential witnesses and those wishing to have access to the proceedings

Eight responses were received, with the views of state and non-state core participants of the Inquiry and the national media all represented.

Following a review of the submissions, the Chairman set out his preliminary conclusions on the Inquiry’s approach to the administration of evidence hearings in a statement on 19 December 2018. A summary can be found in the Inquiry’s eighth update note.

The Chairman will issue a final response to the consultation, together with a protocol for the management and conduct of hearings six months before the start of oral hearings. There will a further opportunity for core participants to provide their views on any new issues set out in the protocol before it is published.

This preliminary issue focused on establishing the legal principles upon which the Chairman would base his decisions on applications for restriction orders and the process of applying for and determining these applications.

A hearing took place from 22 – 23 March 2016, and the Chairman issued a ruling on 3 May 2016. A consultation was then held on a proposal to change the process in December 2017. After reviewing the relevant submissions and witness statements, the Chairman issued a statement outlining the updated approach the Inquiry would be taking.

Further applications from the Metropolitan Police Service

Separately, the Metropolitan Police Service made two related applications:

  • For an extension of time for restriction order applications on behalf of police officers formerly employed by the Special Demonstration Squad; and
  • In respect of the Inquiry’s approach to those restriction order applications.

A hearing took place from 5 – 6 April 2017, and the Chairman issued a ruling on 2 May 2017.

Redacting documents

Given the subject matter of the Inquiry and the high volume of relevant documents expected, the Inquiry anticipates many applications to restrict the publication of information from police bodies and government agencies.

To facilitate processing these applications and avoid the Metropolitan Police Service (MPS) and other state bodies needing to repeat identical submissions the Inquiry has adopted a system which uses generic documents to record grounds, submissions and evidence which it is anticipated will be common to many applications for restrictions. This will avoid unnecessarily delaying the substantive progress of the Inquiry.

The Inquiry’s approach is outlined in paragraphs 8-13 of the ‘Protocol for the Imposition of Restrictions to the Publication of Documents and other Evidence Produced to the Inquiry by the Metropolitan Police Service’ (‘the Restriction Protocol’).

There is evidence that the identities of deceased children and other individuals were used by officers to create their undercover identities. This preliminary issue considers whether:

  • The state has a duty to disclose to the parents of a deceased child that the identity of that child was used for police purposes;
  • There is a public interest test to be applied and, if so, what it comprises and how to measure it.

A hearing took place on 22 June 2016, and the Chairman issued a ruling on 14 July 2016.

On 2 November 2016 the Inquiry Chairman issued a notice inviting parents or close relatives of deceased children who wish to know whether the child’s identity was used by undercover officers to contact the Inquiry by 22 December 2016. A question and answer sheet was prepared to provide more information.

This preliminary issue concerns how to provide individuals with privacy, without undermining the public interest in the Inquiry being conducted as publicly as possible. The Inquiry has also had to consider the extent to which it has an obligation under the General Data Protection Regulations and the Data Protection Act 2018 to provide information to those whose data it is processing.

Hearings took place on 31 January 2019 and 25 March 2019. Following the hearings, the Chairman issued two statements:

This preliminary issue considers the standard of proof that the Chairman should apply to issues of fact that arise in the evidence given to the Inquiry.

On 13 January 2016 the Chairman issued his ruling on the matter, which incorporates the Inquiry Counsel team’s note dated 16 December 2015 and the Chairman’s ‘minded to letter’ dated 17 December 2015.

The Chairman concluded (and the core participants agreed) that he should apply a flexible and variable standard of proof. This means that the starting point is whether it is more likely than not an event occurred (the civil standard), but certain instances may require certainty beyond reasonable doubt (the criminal standard).

This preliminary issue dealt with whether the Inquiry should invite the Attorney General to make an undertaking and, if so, on what terms.

On 28 August 2016, the Attorney General granted the Chairman’s request for an undertaking that meant evidence provided by a witness will not be used against them (or against their spouse or civil partner) in any criminal proceedings, or when deciding whether to bring criminal proceedings.

This was deemed necessary for the Inquiry to fulfil its objective to get to the truth of undercover policing. Without this protection, a witness might choose not to answer a question.

Further information on undertakings can be found in the FAQs.

The Chairman’s ruling on The Rehabilitation of Offenders Act 1974 and its impact on the Inquiry’s work dated 29 November 2017 set out an intention to invite the Secretary of State for Justice to lay before Parliament an amendment to Schedule 3 to the Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975 for the reasons set out in that ruling. This invitation was sent on 12 December 2017. The Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975 (Amendment) (England and Wales) Order 2019 was made on 24 June 2019 and definitively addresses a gap in the statutory scheme for the conduct of inquiries.

The Inquiry requested the amendment for two primary reasons: in order for the Inquiry to fairly examine whether any justification for deployment of an undercover officer was sufficient the Inquiry will need to consider the activities of the individuals and/or groups targeted including their previous convictions and the circumstances ancillary to their convictions which were known by the police at the time of determining whether the deployment was justified. In addition, the Inquiry needs to be able to look at the circumstances surrounding a conviction in order to determine whether any convictions were unsafe due to the unknown involvement of an undercover officer.

As a public inquiry, all open evidence that the Inquiry considers as part of its investigations will be published, subject to any redactions from restriction orders.

Before hearings, general documents – such as annual reports submitted by the Chief Inspector of the SDS to the Special Branch Commander – relevant to the upcoming tranche will be published.

Following each open hearing, the Inquiry will publish a daily transcript of the hearing, together with any documents (e.g. witness statements and supporting evidence) referred to that day.

Once the hearings for a particular tranche has finished, all open evidence considered as part of that tranche – even if it is not expressly referred to during the hearings – will be published.

Below you will find all evidence published to date. Certain documents are accompanied by a schedule that sets out the basis for redactions.



Evidence hearings schedule

Evidence hearings are expected to start in summer 2020. The Inquiry will consider the undercover policing activities of officers and managers and those affected by deployments in tranches ordered chronologically.

The first evidence hearings will focus on officers and managers in the SDS active between 1968 and 1982. This tranche will also include evidence from non-state core participants and witnesses affected by these officers’ deployment. These hearings are expected to last around one month. The Inquiry will usually sit for up to four days per week although both the frequency of hearings and times may vary.

Members of the public are welcome to attend the Inquiry’s open hearings.

The hearings schedule is expected to be published one month before hearings commence.



To date, all open preliminary hearings have been held at the Royal Courts of Justice. The venue for the open evidence hearings has not yet been determined.

Those attending any preliminary hearings at the Royal Courts of Justice should note that security checks are conducted and the following restrictions currently apply:

  • Camera and recording equipment are strictly prohibited and should not be brought into the Royal Courts of Justice.
  • Mobile phones and Blackberry devices must be switched off or switched to ‘silent’.
  • Telephone calls are not permitted in the hearing rooms when the Inquiry is in session. Telephone calls may be made in the hearing rooms during breaks in proceedings but must conclude before the hearing resumes. To make calls during the hearing attendees must leave the hearing room.
  • Text-based media is allowed in the Inquiry hearing rooms and public areas of the Royal Courts of Justice. However, they must not cause a disturbance or distraction to proceedings and are subject to the Chairman’s right to remove that privilege if he believes it is harming the administration of justice; further, by order, no transmission of any statement made during the course of a hearing may be made until a period of 60 seconds has elapsed after the statement is made.
  • Laptops may be used in the Inquiry hearing rooms and public areas if they do not disturb others but they may not be used to make live recordings of proceedings. Laptops must be battery-powered as power sockets are not available.
  • Personal entertainment devices such as MP3 players and iPods may not be used in either hearing room when the Inquiry hearing is in session.
  • The Inquiry Secretariat reserves the right to eject (and if necessary to review the accreditation of) individuals who fail to comply with these conditions.
  • Parking is not available within the Royal Courts of Justice and parking outside the court is extremely limited.
