BROGAN v. UNITED KINGDOM: Extract from ECHR Judgment 56. The Government have argued that in view of the nature and extent of the terrorist threat and the resulting problems in obtaining evidence sufficient to bring charges, the maximum statutory period of detention of seven days was an indispensable part of the effort to combat that threat, as successive parliamentary debates and reviews of the legislation had confirmed (see paragraphs 26-29 above). In particular, they drew attention to the difficulty faced by the security forces in obtaining evidence which is both admissible and usable in consequence of training in anti-interrogation techniques adopted by those involved in terrorism. Time was also needed to undertake necessary scientific examinations, to correlate information from other detainees and to liaise with other security forces. The Government claimed that the need for a power of extension of the period of detention was borne out by statistics. For instance, in 1987 extensions were granted in Northern Ireland in respect of 365 persons. Some 83 were detained in excess of five days and of this number 39 were charged with serious terrorist offences during the extended period. As regards the suggestion that extensions of detention beyond the initial forty-eight-hour period should be controlled or even authorised by a judge, the Government pointed out the difficulty, in view of the acute sensitivity of some of the information on which the suspicion was based, of producing it in court. Not only would the court have to sit in camera but neither the detained person nor his legal advisers could be present or told any of the details. This would require a fundamental and undesirable change in the law and procedure of the United Kingdom under which an individual who is deprived of his liberty is entitled to be represented by his legal advisers at any proceedings before a court relating to his detention. If entrusted with the power to grant extensions of detention, the judges would be seen to be exercising an executive rather than a judicial function. It would add nothing to the safeguards against abuse which the present arrangements are designed to achieve and could lead to unanswerable criticism of the judiciary. In all the circumstances, the Secretary of State was better placed to take such decisions and to ensure a consistent approach. Moreover, the merits of each request to extend detention were personally scrutinised by the Secretary of State or, if he was unavailable, by another Minister (see paragraph 37 above). 57. The Commission, in its report, cited its established case-law to the effect that a period of four days in cases concerning ordinary criminal offences and of five days in exceptional cases could be considered compatible with the requirement of promptness in Article 5 para. 3 (art. 5-3) (see respectively the admissibility decisions in application no. 2894/66, X v. the Netherlands, Yearbook of the Convention, vol. 9, p. 568 (1966), and in application no. 4960/71, X v. Belgium, Collection of Decisions, vol. 42, pp. 54-55 (1973)). In the Commission's opinion, given the context in which the applicants were arrested and the special problems associated with the investigation of terrorist offences, a somewhat longer period of detention than in normal cases was justified. The Commission concluded that the periods of four days and six hours (Mr McFadden) and four days and eleven hours (Mr Tracey) did satisfy the requirement of promptness, whereas the periods of five days and eleven hours (Mr Brogan) and six days and sixteen and a half hours (Mr Coyle) did not. 58. The fact that a detained person is not charged or brought before a court does not in itself amount to a violation of the first part of Article 5 para. 3 (art. 5-3). No violation of Article 5 para. 3 (art. 5-3) can arise if the arrested person is released "promptly" before any judicial control of his detention would have been feasible (see the de Jong, Baljet and van den Brink judgment of 22 May 1984, Series A no. 77, p. 25, para. 52). If the arrested person is not released promptly, he is entitled to a prompt appearance before a judge or judicial officer. The assessment of "promptness" has to be made in the light of the object and purpose of Article 5 (art. 5) (see paragraph 48 above). The Court has regard to the importance of this Article (art. 5) in the Convention system: it enshrines a fundamental human right, namely the protection of the individual against arbitrary interferences by the State with his right to liberty (see the Bozano judgment of 18 December 1986, Series A no. 111, p. 23, para. 54). Judicial control of interferences by the executive with the individual's right to liberty is an essential feature of the guarantee embodied in Article 5 para. 3 (art. 5-3), which is intended to minimise the risk of arbitrariness. Judicial control is implied by the rule of law, "one of the fundamental principles of a democratic society ..., which is expressly referred to in the Preamble to the Convention" (see, mutatis mutandis, the above-mentioned Klass and Others judgment, Series A no. 28, pp. 25-26, para. 55) and "from which the whole Convention draws its inspiration" (see, mutatis mutandis, the Engel and Others judgment of 8 June 1976, Series A no. 22, p. 28, para. 69). 59. The obligation expressed in English by the word "promptly" and in French by the word "aussito^t" is clearly distinguishable from the less strict requirement in the second part of paragraph 3 (art. 5-3) ("reasonable time"/"deŽlai raisonnable") and even from that in paragraph 4 of Article 5 (art. 5-4) ("speedily"/"a` bref deŽlai"). The term "promptly" also occurs in the English text of paragraph 2 (art. 5-2), where the French text uses the words "dans le plus court deŽlai". As indicated in the Ireland v. the United Kingdom judgment (18 January 1978, Series A no. 25, p. 76, para. 199), "promptly" in paragraph 3 (art. 5-3) may be understood as having a broader significance than "aussito^t", which literally means immediately. Thus confronted with versions of a law-making treaty which are equally authentic but not exactly the same, the Court must interpret them in a way that reconciles them as far as possible and is most appropriate in order to realise the aim and achieve the object of the treaty (see, inter alia, the Sunday Times judgment of 26 April 1979, Series A no. 30, p. 30, para. 48, and Article 33 para. 4 of the Vienna Convention of 23 May 1969 on the Law of Treaties). The use in the French text of the word "aussito^t", with its constraining connotation of immediacy, confirms that the degree of flexibility attaching to the notion of "promptness" is limited, even if the attendant circumstances can never be ignored for the purposes of the assessment under paragraph 3 (art. 5-3). Whereas promptness is to be assessed in each case according to its special features (see the above-mentioned de Jong, Baljet and van den Brink judgment, Series A no. 77, p. 25, para. 52), the significance to be attached to those features can never be taken to the point of impairing the very essence of the right guaranteed by Article 5 para. 3 (art. 5-3), that is to the point of effectively negativing the State's obligation to ensure a prompt release or a prompt appearance before a judicial authority. 60. The instant case is exclusively concerned with the arrest and detention, by virtue of powers granted under special legislation, of persons suspected of involvement in terrorism in Northern Ireland. The requirements under the ordinary law in Northern Ireland as to bringing an accused before a court were expressly made inapplicable to such arrest and detention by section 12(6) of the 1984 Act (see paragraphs 30 and 32 above). There is no call to determine in the present judgment whether in an ordinary criminal case any given period, such as four days, in police or administrative custody would as a general rule be capable of being compatible with the first part of Article 5 para. 3 (art. 5-3). None of the applicants was in fact brought before a judge or judicial officer during his time in custody. The issue to be decided is therefore whether, having regard to the special features relied on by the Government, each applicant's release can be considered as "prompt" for the purposes of Article 5 para. 3 (art. 5-3). 61. The investigation of terrorist offences undoubtedly presents the authorities with special problems, partial reference to which has already been made under Article 5 para. 1 (art. 5-1) (see paragraph 53 above). The Court takes full judicial notice of the factors adverted to by the Government in this connection. It is also true that in Northern Ireland the referral of police requests for extended detention to the Secretary of State and the individual scrutiny of each police request by a Minister do provide a form of executive control (see paragraph 37 above). In addition, the need for the continuation of the special powers has been constantly monitored by Parliament and their operation regularly reviewed by independent personalities (see paragraphs 26-29 above). The Court accepts that, subject to the existence of adequate safeguards, the context of terrorism in Northern Ireland has the effect of prolonging the period during which the authorities may, without violating Article 5 para. 3 (art. 5-3), keep a person suspected of serious terrorist offences in custody before bringing him before a judge or other judicial officer. The difficulties, alluded to by the Government, of judicial control over decisions to arrest and detain suspected terrorists may affect the manner of implementation of Article 5 para. 3 (art. 5-3), for example in calling for appropriate procedural precautions in view of the nature of the suspected offences. However, they cannot justify, under Article 5 para. 3 (art. 5-3), dispensing altogether with "prompt" judicial control. 62. As indicated above (paragraph 59), the scope for flexibility in interpreting and applying the notion of "promptness" is very limited. In the Court's view, even the shortest of the four periods of detention, namely the four days and six hours spent in police custody by Mr McFadden (see paragraph 18 above), falls outside the strict constraints as to time permitted by the first part of Article 5 para. 3 (art. 5-3). To attach such importance to the special features of this case as to justify so lengthy a period of detention without appearance before a judge or other judicial officer would be an unacceptably wide interpretation of the plain meaning of the word "promptly". An interpretation to this effect would import into Article 5 para. 3 (art. 5-3) a serious weakening of a procedural guarantee to the detriment of the individual and would entail consequences impairing the very essence of the right protected by this provision. The Court thus has to conclude that none of the applicants was either brought "promptly" before a judicial authority or released "promptly" following his arrest. The undoubted fact that the arrest and detention of the applicants were inspired by the legitimate aim of protecting the community as a whole from terrorism is not on its own sufficient to ensure compliance with the specific requirements of Article 5 para. 3 (art. 5-3). There has thus been a breach of Article 5 para. 3 (art. 5-3) in respect of all four applicants.
