* Nov 2017 'Minded-To': restrict real name.

Ruling (Mar 2018): Real name name cannot be published.Sir John Mitting, In the matter of section 19(3) of the Inquiries Act 2005 Application for restriction order in respect of the real and cover names of officers of the Special Operations Squad and the Special Demonstration Squad Ruling 5 , Undercover Policing Inquiry (UCPI.org.uk), 27 March 2018.
:: HN332 is in his eighties and in poor health. The Inquiry has been provided with a short medical report itemising the serious medical conditions from which he suffers, including one which is life-threatening. His daughter has provided a witness statement in which she says that he suffers from a very poor memory and from confusion. It must, therefore, be unlikely that he could provide useful evidence to the Inquiry.
:: He served in the Special Operations Squad/Special Demonstration Squad in a managerial capacity in the 1970’s. He was the signatory of a significant memorandum dated 17 December 1971. But for his age and health, I would have refused the application for a restriction order in respect of his real name, on the basis that a senior public servant should be willing and, if not, required, to account for his actions publicly. For the reasons explained, no useful purpose would be served by adopting that course; and to do so would risk impairing the peace of mind and even health of a man in his twilight years. I am minded to make a restriction order which will be in place during his life.

On 26 October 2022, the Inquiry revoked the anonymity order protecting HN332's name on the grounds that the officer had died. His family requested that the anonymity remained in order to protect the officer's reputation. Mitting however stated:
:: In those circumstances there is no good reason to shield the acts of a former operational manager of the Special Demonstration Squad from full public scrutiny.
