“…the Court of Appeal had an implicit jurisdiction to do what was necessary to achieve its two principal objectives of correcting wrong decisions and ensuring public confidence in the administration of justice; that, therefore, it could take the exceptional course of reopening proceedings which it had already heard and determined if it was clearly established that a significant injustice had probably occurred and that there was no alternative effective remedy; that, before exercising such a power, the court would consider the effect of reopening the appeal on others and the extent to which the complaining party was the author of his own misfortune; and that where the alternative remedy would be an appeal to the House of Lords the Court of Appeal would only give permission to reopen an appeal if it was satisfied that leave to appeal to the House of Lords would not be given.”
“Counsel accepted that control order proceedings may comply with Article 6 if the Court comes to this conclusion (i.e. that there is no conceivable answer to the Secretary of State’s case) notwithstanding the absence of any meaningful disclosure to the respondent.”
“29. Having considered all the matter placed before us in this way, we were and are entirely satisfied about five things. First, prosecuting counsel have had access to everything they want to see and have examined all relevant and potentially material matter in accordance with the test propounded by Jowitt J in R v Melvin (unreported)20 December 1993 as approved by the Court of Appeal in R v Keane[1994] 1 WLR 746 , 752 and the Court of Appeal and House of Lords in R v Brown (Winston)[1994] 1 WLR 1599 , 1606-1607 and[1998] AC 367 , 376-377, and they have continued to keep the need for disclosure under review. Secondly, the trial judge was correct to rule as he did in relation to the disclosure and non-disclosure of the matter before him. Thirdly, no one has attempted to conceal from this court any relevant or potentially material matter. Fourthly, public interest immunity has been rightly claimed in relation to the matter which we have seen, because it affects national security at the highest level and would, if disclosed, present a clear and immediate threat to life. Fifthly, apart from the two matters to which we shall refer, there is nothing of significance before this court which was not before the trial judge. Having ordered disclosure of these matters to the defendants, in a suitable form, and having heard submissions in relation to them, we are satisfied that no injustice was done to the defendants by not having access to that matter at trial. We say this, first, becausethe matter added nothing of significance to what was disclosed at trial and, secondly, because, for whatever reason, no attempt was made by the defence at trial to exploit, by adducing it in any form before the jury, the similar material in relation to the embassy which had been disclosed at trial. …”
“43. The undisclosed material was first considered by the Court of Appeal in an ex parte hearing prior to the grant of leave to appeal. At the commencement of the hearing of the substantive appeal, the Court of Appeal, in a different composition, heard inter partes submissions on the procedure to be followed in ruling on the Crown's claim for public interest immunity, before deciding to examine the material in an ex parte hearing. The applicants were not represented during this hearing, either by their own counsel or by a specially appointed, security-cleared, counsel (see Edwards and Lewis v. the United Kingdom ([GC], nos. 39647/98 and 40461/98, §§ 43-45, ECHR 2004-X). However, following the disclosure hearing and well in advance of the resumed appeal hearing, the Court of Appeal disclosed to the applicants a summary of the information contained in the first document, as well as an account of the events which had resulted in the fact that the undisclosed material had not been placed before the trial judge. In its judgment of1 November 2001 , the Court of Appeal observed that, save for the material which was given to the applicants in summary form, there was nothing of significance before the court which had not been before the trial judge (see paragraph 18 above). The applicants were given a full opportunity to make submissions on the material which had been disclosed in summary form and on its significance to the issues raised by the case. On the basis of the submissions made, the Court of Appeal concluded that no injustice had been done to the applicants by not having access to the undisclosed matter at trial, since the matter added nothing of significance to what was disclosed at trial and since no attempt had been made by the defence at trial to exploit, by adducing it in any form before the jury, the similar material which had been disclosed at trial. 44. Given the extent of the disclosure to the applicants of the withheld material by the Court of Appeal, the fact that the court was able to consider the impact of the new material on the safety of the applicants' conviction in the light of detailed argument from their defence counsel and the fact that the undisclosed material was found by the court to add nothing of significance to what had already been disclosed at trial, the Court considers that the case bears a stronger similarity to the cases of Jasper and Fitt, Edwards and I.J.L., G.M.R. and A.K.P. (see paragraph 41 above) than to those of Rowe and Davis, Atlan or Dowsett (see paragraphs 38-40 above) and that the failure to place the undisclosed material before the trial judge was in the particular circumstances of the case remedied by the subsequent procedure before the Court of Appeal. 45. There has not, therefore, been a violation of Article 6 in the present case.”
“The conclusion which I draw from the four speeches of the majority in MB is that unless, at a minimum, the special advocates are able to challenge the Secretary of State's grounds for suspicion on the basis of instructions from the controlled person which directly address their essential features, the controlled person will not receive the fair hearing to which he is entitled except, perhaps, in those cases in which he has no conceivable answer to them. In practice, this means that he must be told their gist. This means that, if he chooses to do so, he can give and call evidence about the issues himself.”
