“22. The relevant rules are contained inCPR Part 82 . Ms Rose preferred to concentrate on the requirements laid down by section 8 itself rather than on the way in which effect has been given to those requirements in the detailed rules. I should, however, note that the main rules governing an application to withhold sensitive material as referred to in section 8 are CPR rules 82.13 and 82.14, and that two sub-paragraphs of rule 82.14 call for particular comment. Sub-paragraph (7) provides that where the court gives permission to the relevant person to withhold sensitive material, the court (a) must consider whether to direct the relevant person to serve a summary of that material on the specially represented party and the specially represented party’s legal representative, but (b) “must ensure that any such summary does not contain material the disclosure of which would be damaging to the interests of national security. Subparagraph (10) provides that the court “must give permission to the relevant person to withhold sensitive material where it considers that disclosure of that material would be damaging to the interests of national security”
“23. In summary, therefore, the requirements of article 6 depend on context and all the circumstances of the case. The particular circumstances in Tariq included the fact that (i) it did not involve the liberty of the subject; (ii) the claimant had been provided with a degree of information as to the basis for the decision to withdraw his security vetting: he was not completely in the dark; (iii) there was real scope for the special advocate to test the issue of discrimination without obtaining instructions on the facts from the claimant; and (iv) this was a security vetting case and it was clearly established in the Strasbourg jurisprudence that an individual was not entitled to full article 6 rights if to accord him such rights would jeopardise the efficacy of the vetting regime itself (para 159).”
“8. The essence of the decision in AF (No 3) is that fairness and Article 6 dictate that an individual against whom a control order is made must be given sufficient information about the allegations against him to enable him to give effective instructions to his special advocate in relation to them to enable the special advocate to deal with them in any closed hearing. This does not mean that there needs to be a detailed disclosure of the sources of the evidence upon which the allegations are based, but if the disclosure is limited to general assertions so that the case against the controlee is based solely or to a decisive extent on undisclosed material, there cannot be a fair trial compliant with Article 6. It was recognised that this could mean in a given case that a dangerous terrorist could avoid control if adequate disclosure was impossible because of the risk to national security.”
“15. It seems that the result of this is that, however strong the evidence relied on by the SSHD may be to establish the necessary reasonable suspicion, the order will not have been lawfully imposed unless disclosure which complied with AF(No.3) could be made when the court came to consider whether the decisions of the SSHD in making the order or imposing any of the obligations in it were flawed on a hearing pursuant to s.3 of the 2005 Act.”
“23. If no disclosure is required for this court to be acting in a manner consistent with Article 6, the issue of whether disclosure cannot be permitted because of the damage to national security has already been resolved by the decisions of Mitting J, which obviously apply to the material produced on behalf of the Defendants after the 8 September hearing. Further disclosure was not sought on the basis that any of that further material could be disclosed without such damage. 24. Disclosure was sought on some other basis. We can reject at the outset the suggestion that some common law duty of fairness required further disclosure to a level akin to that which Article 6 might require. There is no such duty once proceedings have entered the statutory closed materials procedure. Disclosure is entirely governed by the JSA. If the upshot of the disclosure process is that, on a review under s.7, the s.6 declaration has to be revoked, with whatever consequences that leads to for one side or the other, then that is the answer of the JSA to the question of whether the declaration is no longer in the interests of the fair and effective administration of justice. 25. It is only if the disclosure to the extent ordered would require this court to act inconsistently with Article 6 that further disclosure has to be considered. The principles on which it would then act can be summarised as follows. In Secretary of State for the Home Department v AF (No.3)[2009] UKHL 28 , [2010] 2 AC, Lord Phillips referred to the principle at [59] (in the context of control orders) applying the approach of the Grand Chamber of the ECtHR in A v. United Kingdom (2009) 49 EHHR 625, and concluded that (in that case, the controlee) had to be ‘given sufficient information about the allegations against him to enable him to give effective instructions in relation to those allegations’. “Provided this requirement is satisfied there can be a fair trial notwithstanding that the controlee is not provided with the detail or the sources of the evidence forming the basis of the allegations. Where, however, the open material consists purely of general assertions and the case against the controlee is based solely or to a decisive degree on closed materials the requirement of a fair trial will not be satisfied, however cogent the case based on the closed materials may be.”
“where detail matters, as it often will, detail must be met with detail ...” 26. The inherent tension, between the requirement of fairness in the trial process, that a party should know the case against him, and the interest of national security in not disclosing particularly sensitive information, was discussed later in the speech of Lord Phillips at [63], and it was partly as a result of his invitation to Parliament to consider how that tension should be resolved consistently with the ECHR (see [64]) that the JSA 2013 was enacted by Parliament. 27. One further matter of generality may be noted at this stage: namely, that if it is a case to which Article 6 applies, the extent of the requirement to give disclosure will depend on context and all the circumstances of the case, see, for example, Bank Mellat v. HM Treasury[2015] EWCA Civ 1052 , Richards LJ at [14].” “Provided this requirement is satisfied there can be a fair trial notwithstanding that the controlee is not provided with the detail or the sources of the evidence forming the basis of the allegations. Where, however, the open material consists purely of general assertions and the case against the controlee is based solely or to a decisive degree on closed materials the requirement of a fair trial will not be satisfied, however cogent the case based on the closed materials may be.” “where detail matters, as it often will, detail must be met with detail ...”
“135. The purpose of section 68(4) of the Act read together with rules 13 and 6 of the Rules is to my mind reasonably clear. There is a strong public interest that a successful complainant and the public should know that an unlawful interception has taken place subject to the need to restrict disclosure of reasons in protection of the public interest, national security or the continued functioning of the Intelligence Services. However, the public interest in preserving effective investigation requires that no unsuccessful claimant should be provided with the means of defeating an investigation. These provisions strike a public interest balance: in the case of a successful complainant blanket application of the ‘Neither Confirm Nor Deny’ policy gives way, to a limited degree, to the requirements of open justice; in the case of an unsuccessful complainant, however, he would be unable to draw an inference as to whether his communications had been intercepted or not.”
“A person may apply … to withhold disclosure of a document on the ground that disclosure would damage the public interest.”
