* 2 May 2018: Mitting minded to restrict real and cover names,Steven Gray, Counsel to the Inquiry's Explanatory Note to accompany the Chairman's 'Minded To' Note 12 in respect of applications for restrictions over the real and cover name of officers of the National Public Order Intelligence Unit and its predecessor/successor units, Undercover Policing Inquiry, 2 May 2018. writing:Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the National Public Order Intelligence Unit and its predecessor/successor units 'Minded to' Note, Undercover Policing Inquiry, 2 May 2018.
:: EN507 is a serving police officer and has undertaken undercover operations w hich put safety at risk. The continued ability of the police service to deploy EN507 in undercover operations is of public value. Publication of the cover name would substantially impair the undertaking of such operations. It is not in the public interest to do so.
:: Further, publication of either real or cover name would interfere with the right of EN507 to respect for private and family life and would not be justified...

* 30 October 2018: Mitting rules to restrict both real and cover names, writing:Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the National Public Order Intelligence Unit and its predecessor/successor units Ruling 1 and 'Minded to' 2, Undercover Policing Inquiry, 30 October 2018.
:: The submissions assert that there is no reference in the 'Minded to' note to any risk of physical harm. There is: "EN507 is a serving police officer and has undertaken undercover operations which put safety at risk." It is correct that that assessment was based on EN507's account, which I have no reason to disbelieve. I do not accept that the public interest in the disclosure of the cover name of EN507 outweighs the public interest in the continued ability of the police service to deploy EN507 in undercover operations of public value, for the reasons explained in the closed note which accompanied the 'Minded to' note.
