Judgment Approved by the court for handing down. 12. Miranda v SSHD At para 29 of his first witness statement, Det Supt Stokley said: “It appeared from the national security justification that Edward SNOWDEN held a large amount of information the disclosure of which could be highly damaging to UK national interests. This reinforced my view that the value of the material that Mr MIRANDA might be carrying to a hostile state engaged in terrorist activity or a terrorist organisation was enormous and its disclosure to agents of a hostile state or a terrorist organisation elsewhere would be catastrophic. In the circumstances, I considered that Schedule 7 paragraph 8 in particular, permitted us to search him to ascertain whether he had the material in his possession to assist in the determination of whether or not he was a person concerned in the commission, preparation or instigation of acts of terrorism.” 13. On Friday 16 August, a PCS was issued by the Security Service to the MPS and received at the National Ports Office at 21.59. On page 2, against a box asking for confirmation “that the purpose of an examination will be to assist in making a determination about whether the person appears to be someone who is or has been concerned in the Commission, Preparation or Instigation of acts of terrorism (CPI)”, the Security Service had entered the words “Not Applicable”. On the same page this was stated: “Intelligence indicates that MIRANDA is likely to be involved in espionage activity which has the potential to act against the interests of UK national security. We therefore wish to establish the nature of MIRANDA’s activity, assess the risk that MIRANDA poses to UK national security and mitigate as appropriate. We are requesting that you exercise your powers to carry out a ports stop against MIRANDA.” 14. This PCS was not actively considered by the MPS when it was received. A second PCS was received at the National Ports Office on Saturday 17 August at 12.47. This too contained the “Not Applicable” entry, and also the invitation to the police to carry out a port stop (plainly a reference to Schedule 7). Another section, headed “Guidance for Port Officers”, was considerably expanded, setting out a series of questions which the Security Service desired should be asked of Mr Miranda. 15. Acting DI Woodford was the Ports Duty Officer for Heathrow Airport over the weekend 17 – 18 August. He viewed the second PCS at the request of PS Holmes, who had received it. He “immediately saw that the PCS did not give sufficient information to provide police with the assurance that the use of Schedule 7 would be appropriate and lawful” (para 11 of his witness statement). He considered that the “Not Applicable” entry was in conflict with the invitation to the police to carry out a port stop under Schedule 7. He thought that the Security Service “may have been reluctant to confirm that the stop was for the purposes of determining whether Mr MIRANDA was a person concerned in the commission, preparation or instigation of acts of terrorism (“CPI”) in circumstances where their concern appeared to revolve around espionage and national security issues” (para 12). He agreed with PS Holmes that the PCS should be returned to the Security Service for confirmation that “the
