:: HN351 is in his 70s... He was withdrawn from his deployment because of health problems of unclear origin. None of the members of the target group or their associates pose any threat to his safety. In 2016, he was diagnosed as suffering from an aggressive form of cancer. The cancer has responded well to treatment and may not have metastasised. He is concerned about the impact on him and his family of the disclosure of his real name. In the opinion of his treating consultant oncologist, it is not possible to link the anxiety and stress likely to be caused by publication of his real name to the progress of his condition. In her opinion, he can be expected to provide a witness statement without adverse impact on his health.
:: Even though HN351 's concerns may not be objectively justified, I accept that they are genuine. There is no need to override them. Publication of his cover name, which will occur, may serve to prompt those who encountered him during his deployment to provide or give evidence about it. Publication of his real name could not do so. It is not necessary to permit the terms of reference of the Inquiry to be fulfilled. The interference which it would cause in HN351's right to respect for private and family life would be disproportionate and unjustified under Article 8(2) of the European Convention.
