“73… this gives the greatest possible incentive to all parties in the case, and to the judge, to conduct the proceedings in such a way as to afford a sufficient and substantial measure of procedural injustice”. (emphasis in the original) She also accepted (with my emphasis added) that: “there may still be a few cases in which under the scheme set out in the 2005 Act and Rules,[ a substantial and sufficient measure of procedural protection] is not possible”[68] Baroness Hale had explained earlier in paragraph 66 that it was not possible to be confident that the Strasbourg Court would hold that in every control order hearing in which the Special Advocate procedure had been adopted, the article 6 rights of the controlled person had been complied with. (b) Lord Carswell explained (again with my emphasis added) that: “85. There is a fairly wide spectrum of cases in which closed material is relied on by the Secretary of State. At one extreme there may be cases in which the sole evidence adverse to the controlee is closed material, he cannot be told what the evidence is or even given its gist and the special advocate is not in a position to take sufficient instructions to mount an effective challenge to the adverse allegations. At the other end there may be cases where the probative effect of the closed material is very slight or merely corroborative of strong open material and there is no obstacle to presenting a defence. There is an infinite variety of possible cases in between. The balance between the open material and the closed material and the probative nature of each will vary from case to case. The special advocate may be able to discern with sufficient clarity how to deal with the closed material without obtaining direct instructions from the controlee. These are matters for the judge to weigh up and assess in the process of determining whether the controlee has had a fair trial. The assessment is, as Lord Woolf CJ said in Roberts[2005] 2 AC 738 , at paragraph 77, fact-specific. The judge who has seen both the open and the closed material and had the benefit of the contribution of the special advocate is in much the best position to make it. I do consider, however, that there is a fairly heavy burden on the controlee to establish that there has been a breach of article 6, for the legitimate public interest in withholding material on valid security grounds should be given due weight. The courts should not be too ready to hold that a disadvantage suffered by the controlee through the withholding of material constitutes a breach of article 6”. and c) Lord Brown said (again with my emphasis added) that: “90 …I agree further that the special advocate procedure, highly likely though it is that it will in fact safeguard the suspect against significant injustice, cannot invariably be guaranteed to do so. There may perhaps be cases, wholly exceptional though they are likely to be, where, despite the best efforts of all concerned by way of redaction, anonymisation and gisting, it will simply be impossible to indicate sufficient of the Secretary of State’s case to enable the suspect to advance any effective challenge to it.”
