In the Undercover Policing Inquiry
An application was made by the MPS to restricting real name, submitted along with evidence from family and a risk assessment - of which open versions were published in August 2017.
In his 'Minded-to' of August 2017, the Inquiry Chair, John Mitting, said he intended to restrict the real name, noting:
- There is no risk to their safety and minimal risk of intrusive interest in them even if his real name were to be published. They wish to avoid that risk. Although the risk is minimal, nothing would be gained by running it. Unless HN294’s cover name were to become known, publication of his real name could not prompt evidence from one or more members of the affected groups. Evidence about his managerial role, if it is available, can be given by others who knew him, by reference to his cypher. In those circumstances, interference with the right of his widow and family to respect for their private life under Article 8 of the European Convention would not be justifiable under Article 8(2).
August 2017 application: Open application for restriction order, open risk assessment (Brian Lockie), open personal statement (1), open personal statement (2). See also the NPSCP submissions of 5 October 2017.
The application was heard at the hearing of 21 November 2017, and Mitting ruling in favour of restricting the real name on 5 December. The grounds for the ruling were interference with the rights of the widow (a family member having written on her behalf) despite their being 'no risk to the safety of his widow and family and minimal risk of intrusive media interest in them if his real name were to be published)'. He also said the submission that the chance the public being able to provide details of HN294's time undercover if they had his real name was 'fanciful', so it was not necessary to provide the real name in order to fulfil the Inquiry's terms of reference. The Restriction Order was issued on 8 December 2017.
