Habeas corpus
60 As set out in the Introduction, STCA contends that, where it appears that the respondent to an application for a writ of habeas corpus has control over the detention of the relevant person or, at least, the Court entertains a doubt as to whether the respondent has control, the Court can use the "pressure of the writ" to test the truth of the respondent's assertion of a lack of control. STCA relies on Barnardo, O'Brien and Rahmatullah in support of that contention. STCA contends that, in the present case, it appears that the respondents have control over the detention of the relevant woman and children or, at least, there is doubt as to whether the respondents have control.
61 I will put to one side, at this stage, the issue of standing. There is no issue that STCA has standing in relation to the STCA Women and Children. The issue whether a writ of habeas corpus should issue therefore needs to be considered in any event in relation to those women and children.
62 I will start by considering the three cases relied on by STCA. I approach these cases on the basis that, while not binding on me, they are persuasive authority as to the principles applicable to the writ of habeas corpus.
63 The first of the three cases, Barnardo, a judgment of the House of Lords, concerned an application by a parent for a writ of habeas corpus in respect of a child. The application was directed to Dr Barnardo, who was the head of an institution for destitute children in which the child has been placed. Dr Barnardo filed an affidavit stating that, before the commencement of the proceeding, he had handed over the child to another person (a Mr William Norton), an American, and that he (Dr Barnardo) believed that the boy had been taken by Mr Norton to Canada. Dr Barnardo further deposed that he had not, since he handed over the child, heard from the child or Mr Norton, that he did not know where the child or Mr Norton was, and that he had no means of communicating with either of them.
64 The House of Lords affirmed the decision of the Court of Appeal that a writ of habeas corpus should issue. All members of the House of Lords agreed in the result. Separate judgments were delivered by each of the Law Lords, namely Lord Halsbury LC, Lord Watson, Lord Herschell, Lord Macnaghten, Lord Morris and Lord Hannen. Lord Morris agreed with the reasons given in the Queen's Bench Division and in the Court of Appeal. Lord Hannen agreed with the reasons of Lord Herschell.
65 Lord Halsbury referred (at 332) to the fact that, late in the argument, it became apparent that the parties (or, at least, one of them) did not consider that all the facts had already been ascertained, and desired a return to the writ so that, upon the return, further questions of evidence might be raised. Lord Halsbury stated (at 333) that where a Court is satisfied that illegal detention has ceased before the application for the writ was made, the writ ought not issue "as it is not the appropriate procedure for punishing such conduct". However, treating the facts of the present case as still open to inquiry, he held that the appeal should be dismissed (i.e. the writ should issue) on the ground that "the respondents have a right to the return".
66 Lord Watson's judgment was similar to that of Lord Halsbury. Lord Watson stated (at 333) that the remedy of habeas corpus "was not meant to afford the means of inflicting penalties upon those persons by whom they were at some time or other illegally detained". Lord Watson stated (at 335) that, where it is shown to the satisfaction of the Court that the person charged with unlawfully detaining a child or adult had de facto ceased to have any custody or control, the writ should not issue. However, he agreed (at 336) with the opinion of the other Law Lords that the present case "may be more conveniently disposed of after a return has been made to the writ".
67 Lord Herschell stated (at 338) that he could not feel satisfied that it is not a good return to the writ that the person to whom it relates was not at the time it was issued in the custody, power or control of the person on whom it is served. His Lordship stated (at 339-340):
Where any tribunal believes that a person is or may be under detention in unlawful custody, and issues a writ of habeas corpus accordingly, no Court of Appeal ought lightly to interfere with the issue of the writ. The order for its issue ought only to be set aside if there be, beyond question, no ground for it. If, for example, in the present case it had been an admitted fact that before notice of the application for the writ the appellant had ceased to have the custody of or any control over the boy alleged to be detained, that might have been ground for reversing the order of the Queen's Bench Division. But where the Court entertains a doubt whether this be the fact, it is unquestionably entitled to use the pressure of the writ to test the truth of the allegation, and to require a return to be made to it. Now, it is impossible to read the judgment of the Lord Chief Justice without seeing that he did entertain such a doubt, and that he was not prepared upon the affidavits to accept as conclusive the statements of the appellant. At your Lordships' bar the counsel for the respondent contended that they had a right to cross-examine the appellant, and that the proper occasion on which to try the question was when he had returned to the writ that he was not detaining the child, and that it was not, at the time the writ was issued, in his custody, power, or control. I think this view is the correct one; the truth of the return may, no doubt, be put in issue, and I feel myself unable to advise your Lordships that the Queen's Bench Division were not in point of law justified in issuing the writ.
(Emphases added.)
68 Lord Macnaghten stated (at 340) that he could not say that this is a case in which there ought not be an opportunity of further inquiry into the circumstances under which Dr Barnardo parted with the child, and "ascertaining beyond all doubt whether the child is or is not still under Dr Barnardo's control or within his reach".
69 The second case relied on by STCA is O'Brien, a judgment of the English Court of Appeal. An appeal to the House of Lords was dismissed on jurisdictional grounds (see below).
70 The background facts were as follows. Regulation 14B of the Restoration of Order in Ireland Regulations 1920 (UK) gave the Secretary of State for Home Affairs (the Home Secretary) power to order the internment in a place in the British Islands of any person suspected of acting, or having acted, or being about to act, in a manner prejudicial to the restoration or maintenance of order in Ireland. On 5 December 1922, the Irish Free State Constitution Act 1922 (UK) was passed. By the Act, the Irish Free State was given a distinct and independent executive. On 7 March 1923, the Home Secretary made an order under reg 14B that Mr O'Brien, who was then residing in England, should be interned in such place in the Irish Free State as the Irish Free State Government should determine. Mr O'Brien was arrested in London under that order and conveyed to Dublin, where he was interned in Mountjoy Prison. There was an agreement between the Home Secretary and the Irish Free State Government that, if a certain advisory committee reported that Mr O'Brien ought not to have been interned, the Irish Free State Government would release him. Mr O'Brien applied to a Divisional Court for a rule nisi for a writ of habeas corpus directed to the Home Secretary.
71 In his affidavit, the Home Secretary stated that Mr O'Brien was in the custody and control of the Governor of the Mountjoy Prison and that the Governor of the prison was an official of the Irish Free State Government and was not subject to the orders or directions of the Home Secretary or the British Government.
72 The Divisional Court refused the rule nisi. Mr O'Brien applied to the Court of Appeal, which granted a rule nisi. At the subsequent hearing before the Court of Appeal, the Home Secretary contended (among other things) that the application was directed against the wrong person. It was contended that any writ of habeas corpus should be directed to the person who has control of the applicant's body, who in this case was the Governor of Mountjoy Prison. It was contended that the fact that the Home Secretary ordered the arrest did not make him a proper person to whom to direct the writ.
73 The Court of Appeal held that the rule nisi be made absolute (in effect, that a writ of habeas corpus issue against the Home Secretary). There are two aspects to the Court's reasoning. First, the Court held that reg 14B was inconsistent with the Irish Free State Constitution Act 1922, and was impliedly repealed by it, and that the order of internment was consequently invalid. Secondly, the Court held that the application was properly made against the Home Secretary. It is the Court's reasoning on the second aspect that is relevant for present purposes.
74 Separate judgments were delivered by Bankes LJ, Scrutton LJ and Atkin LJ.
75 Bankes LJ considered (at 381) the Home Secretary's contention that, as Mr O'Brien had been deported to and was interned in the Irish Free State, the Home Secretary no longer had any power or control over him (except insofar as the Irish Free State Government had agreed that, in the event the advisory committee decided that Mr O'Brien ought not to have been deported and interned, they would release him). Bankes LJ referred to statements made by the Home Secretary in the House of Commons to the effect that he had not lost control over persons who, by his orders, had been interned in the Irish Free State. Bankes LJ stated (at 381):
In his affidavit he [i.e. the Home Secretary] states that the Governor of the Mountjoy Prison is an official of the Free State Government, and is not subject either to his orders or to those of the British Government. This is no doubt an accurate statement in reference to the Governor of the prison, but it leaves the question in doubt how far, if at all, by arrangement with the Free State Government the body of the applicant is under the control of the Home Secretary. This question cannot, I think, be satisfactorily disposed of unless the rule is made absolute which will give the Home Secretary the opportunity, if he desires to take advantage of it, of making the position clearer than at present it appears to be. This was the course taken in Barnardo v. Ford, and is, in my opinion, the appropriate course to take in the present case. The order, therefore, is made absolute.
(Footnote omitted.)
76 Scrutton LJ considered (at 391-392) the question whether a writ of habeas corpus was the appropriate remedy for the illegality of the order and detention. Scrutton LJ stated (at 391):
Now it has been laid down by the House of Lords in Barnardo v. Ford that if the Court is satisfied that the body whose production is asked is not in the custody, power or control of the person to whom it is sought to address the writ, a writ of habeas corpus is not the proper remedy, though there was an original illegal taking and detention. The object of the writ is not to punish previous illegality, but to release from present illegal detention. I do not wish to tie myself to the exact degree of power over the body which justifies the issue of the writ, for various high authorities have used different words. Lord Herschell's language is "custody, power or control"; Lord Macnaghten's "under control or within reach"; Lord Halsbury's "wrongful detention by himself or his agent."
(Footnotes omitted.)
77 After referring to the Home Secretary's statement in the House of Commons that he had not lost control over internees in the Irish Free State, and the Home Secretary's affidavit evidence that Mr O'Brien was in the custody or control of an Irish official who was not subject to the orders or directions of the Home Secretary, Scrutton LJ stated (at 392):
On this conflicting evidence, all proceeding from the Home Secretary himself, it appears to me quite doubtful whether or not, if an order is made for the production of the body, the Home Secretary can or cannot produce that body. Under these circumstances I think the proper course to follow is that affirmed by the House of Lords in Barnardo v. Ford.
(Footnote omitted.)
78 Atkin LJ considered (at 398-399) the question whether the writ should go to the Home Secretary. In relation to this issue, Atkin LJ stated in part (at 398-399):
I think that the question is whether there is evidence that the Home Secretary has the custody or control of the applicant. Actual physical custody is obviously not essential. "Custody" or "control" are the phrases used passim in the opinions of the Lords in Barnardo v. Ford, and in my opinion are a correct measure of liability to the writ.
…
In testing the validity of the order the question is as to the legal right to control; in testing the liability of the respondent to the writ the question is as to de facto control. In all cases of alleged unjustifiable detention such as arise on applications for the writ of habeas corpus the custody or control is ex hypothesi unlawful; the question is whether it exists in fact. In the present case there may be some doubt. The Home Secretary by the Attorney-General alleged that he has no control; on the other hand the applicant by his affidavit submits reasons for supposing that the Home Secretary is in a position by agreement to cause him to be returned to England, while the answer of the Home Secretary does not in terms deny that he is in such a position; and refrains from stating that he has no control.
The affidavit states that the applicant is in the control of the governor of the prison, and is not subject to the Home Secretary's orders, but this is by no means inconsistent with an agreement with the Free State Government to return on request. I think moreover that the applicant strengthens his case by the reference to the debate in Parliament on Monday, March 19, 1923, a report of which was put in. But without further explanation it seems to me that much support for the contention that the Home Secretary retains de facto control is afforded by the words of the order itself, a copy of which is served on the applicant. The order is that the applicant shall "be interned in the Irish Free State . . . . and shall remain there until further orders." It was conceded that the ordinary interpretation of those words would be until further orders by the Home Secretary, though it was said that in fact he had no power to give such orders. I cannot without further explanation accept this.
…
I cannot explain these provisions on the footing that there is no de facto control. In this case it is plain that the applicant was at one time in the custody and control of the Home Secretary by an order which we have held to be illegal. There is, to say the least, grave doubt whether he is not still in the custody or control of the Home Secretary. The case of Barnardo v. Ford appears to me to afford ample ground for the conclusion that this Court should order the writ to go addressed to the Home Secretary in order that he may deal fully with the matter, and if he has in fact parted with control show fully how that has come about. The rule must be made absolute.
(Footnotes omitted.)
79 As noted above, an appeal to the House of Lords was dismissed on jurisdictional grounds: Secretary of State for Home Affairs v O'Brien [1923] AC 603. Lord Atkinson dissented on that issue. It appears from a passage at 624 that he approved of the Court of Appeal's analysis.
80 The third case relied on by STCA is Rahmatullah, a judgment of the Supreme Court of the United Kingdom. The background facts were as follows. Mr Rahmatullah, a national of Pakistan, was captured by British Forces in Iraq in 2004 and handed over to United States forces, who transferred him to Afghanistan, where he was detained at a United States airbase. At that time, a memorandum of understanding between the Governments of the United States, the United Kingdom and Australia (the 2003 MoU) was in place. The 2003 MoU provided that it was to be implemented in accordance with the Geneva Convention relative to the Treatment of Prisoners of War (GC3) and the Geneva Convention relative to the Protection of Civilian Persons in Time of War (GC4), as well as customary international law. Clause 4 of the 2003 MoU provided:
Any prisoners of war, civilian internees, and civilian detainees transferred by a detaining power [the UK] will be returned by the accepting power [the US] to the detaining power without delay upon request by the detaining power.
81 In 2008, a revised memorandum of understanding was concluded between the Governments of the United States and the United Kingdom (the 2008 MoU). (This was not signed until 2009.)
82 An application was made on behalf of Mr Rahmatullah for a writ of habeas corpus directed to the Secretary of State for Defence and the Secretary of State for Foreign and Commonwealth Affairs. The Divisional Court of the Queen's Bench Division refused the application. On appeal, the Court of Appeal allowed the appeal and held that the writ of habeas corpus should issue: Rahmatullah v Secretary of State for Defence [2011] EWCA Civ 1540; [2012] 1 WLR 1462. The United Kingdom Government then requested the United States authorities to return Mr Rahmatullah. In response, the United States authorities stated that Mr Rahmatullah's detention was proper and consistent with the international law of armed conflict. A further hearing took place before the Court of Appeal. In a second judgment, the Court of Appeal held that the United Kingdom authorities had made a sufficient return to the writ.
83 The Secretaries of State appealed against the first judgment and Mr Rahmatullah appealed against the second judgment. The United Kingdom Supreme Court dismissed both appeals. In relation to the first judgment of the Court of Appeal, all members of the Supreme Court were of the view that the appeal should be dismissed. In relation to the second judgment of the Court of Appeal, a majority were of the view that the appeal should be dismissed (with Baroness Hale of Richmond and Lord Carnwath JJSC dissenting).
84 Reasons for judgment were delivered by Lord Kerr of Tonaghmore JSC (with whom Lord Dyson MR and Lord Wilson JSC agreed), Lord Phillips of Worth Matravers and Lord Reed JSC. A joint judgment was delivered by Lord Carnwath and Baroness Hale JJSC. For present purposes, it is sufficient to focus on the parts of the judgments dealing with the appeal from the first judgment of the Court of Appeal.
85 Lord Kerr JSC (at [17]) noted evidence (on behalf of the Secretaries of State) that the 2008 MoU was designed to replace and supersede the 2003 MoU. Lord Kerr JSC stated that he was not disposed to accept that claim (for reasons he gave). He also stated that, even if the 2008 MoU did indeed supersede the 2003 MoU, there was no reason to conclude that it had done so for prisoners already transferred under the earlier arrangements. He therefore considered that the UK Government remained entitled to have recourse to the 2003 MoU to demand Mr Rahmatullah's release to them. Lord Kerr JSC stated (at [17]):
This provides a sufficient basis for the finding that there was at least uncertainty as to whether the UK could exert control over Mr Rahmatullah. That uncertainty was enough to justify the issue of the writ.
86 Lord Kerr JSC set out some general principles regarding habeas corpus at [41]-[44]. This section included (at [43]):
The effectiveness of the remedy would be substantially reduced if it was not available to require someone who had the means of securing the release of a person unlawfully detained to do so, simply because he did not have physical custody of the detainee - "actual physical custody is obviously not essential" per Atkin LJ in Ex p O'Brien [1923] 2 KB 361, 398 and Vaughan Williams LJ in R v Earl of Crewe, Ex p Sekgome [1910] 2 KB 576, 592, stating that the writ "may be addressed to any person who has such control over the imprisonment that he could order the release of the prisoner".
87 The next section of the judgment, at [45]-[64], concerned "control". Lord Kerr JSC stated (at [45]):
At the heart of the cases on control in habeas corpus proceedings lies the notion that the person to whom the writ is directed has either actual control of the custody of the applicant or at least the reasonable prospect of being able to exert control over his custody or to secure his production to the court. Thus in Barnardo v Ford [1892] AC 326 where the respondent to the writ had consistently claimed to have handed the child, who was the subject of the application, over to someone whom he was no longer able to contact, the courts nevertheless ordered that the writ should issue because they entertained a doubt as to whether he had indeed relinquished custody of the child. There was therefore a reasonable prospect that the respondent, despite his claims, either had or could obtain custody of the child.
(Emphasis added.)
88 Lord Kerr JSC discussed O'Brien, stating (at [48]) that "there was at least a reasonable prospect that the Home Secretary could procure Mr O'Brien's return to England". Lord Kerr JSC stated (at [48]):
This highlights the factual nature of the inquiry that must be made as to whether a sufficient degree of control exists. It is not simply a question of the legal enforceability of any right to assert control over the individual detained. The question is, as Atkin LJ put it, whether control "exists in fact".
89 At [52], Lord Kerr JSC stated that a critical, if not the central, issue in O'Brien was "that there was reason to conclude that the Home Secretary had control over Mr O'Brien's release". Lord Kerr JSC stated (at [52]):
Habeas corpus was issued in his case not simply because it was held that he had been deported and interned on foot of an order which, it was found, had not been lawfully made. The issue of the writ depended crucially on the finding that it was likely that the Home Secretary could procure Mr O'Brien's release.
90 At [55]-[57], Lord Kerr JSC discussed Ex parte Mwenya [1960] 1 QB 241, noting that there was a clear distinction between the facts of that case and those of O'Brien. Lord Kerr JSC stated (at [57]): "Whereas in O'Brien there were "strong grounds" for believing that the Home Secretary had not lost control over Mr O'Brien's detention, in Mwenya no such grounds existed."
91 In the course of rejecting an argument that the writ in the present case had the effect of requiring the Secretaries of State to engage at a diplomatic level with the custodian state, the US, Lord Kerr JSC stated (at [60]):
… In the first place, the Court of Appeal's decision [i.e. in the present case] does not amount to an "instruction" to the Government to demand Mr Rahmatullah's return. Its judgment merely reflects the court's conclusion that there were sufficient grounds for believing that the UK Government had the means of obtaining control over the custody of Mr Rahmatullah. On that basis the court required the Secretaries of State to make a return to the writ. The essential underpinning of the court's conclusion was that there was sufficient reason to believe that the Government could obtain control of Mr Rahmatullah. It might well prove that the only means of establishing whether in fact it could obtain control was for the Government to ask for his return but that remained a matter for the ministers concerned. The Court of Appeal's judgment did not require the Secretaries of State to act in any particular way in order to demonstrate whether they could or could not exert control. What it required of them was that they show, by whatever efficacious means they could, whether or not control existed in fact.
92 At [61]-[62], Lord Kerr JSC discussed In re Sankoh (2000) 119 ILR 386. Lord Kerr JSC concluded his discussion of "control" as follows:
63 For the reasons that I have given at para 60 above, I do not consider that the effect of the Court of Appeal's decision in the present case is to require the British Government to engage in a process of persuasion. It does not involve an attempt to "dictate to the executive government steps that it should take in the course of executing Government foreign policy". Rather it requires the Government to test whether it has the control that it appeared to have over the custody of Mr Rahmatullah and to demonstrate in the return that it makes to the writ that, if it be the case, it does not have the control which would allow it to produce the body of [Mr Rahmatullah] to the court.
64 An applicant for the writ of habeas corpus must therefore demonstrate that the respondent is in actual physical control of the body of the person who is the subject of the writ or that there are reasonable grounds on which it may be concluded that the respondent will be able to assert that control. In this case there was ample reason to believe that the UK Government's request that Mr Rahmatullah be returned to UK authorities would be granted. Not only had the 2003 MoU committed the US armed forces to do that, the Government of the US must have been aware of the UK Government's view that Mr Rahmatullah was entitled to the protection of GC4 and that, on that account, it was bound to seek his return if (as it was bound to do) it considered that his continued detention was in violation of that Convention.
(Emphasis added.)
93 I turn now to the other judgments. Lord Phillips of Worth Matravers stated (at [90]-[91]):
90 Habeas corpus will lie not merely against a defendant who is himself detaining the prisoner, but against a defendant who holds the prisoner in his custody or control through another.
91 Typically habeas corpus lies against a defendant who is detaining the prisoner within the jurisdiction of the court. Where a defendant, who is within the jurisdiction, has unlawfully detained the prisoner within the jurisdiction and unlawfully taken him out of the jurisdiction, where he still holds him in his custody or control, habeas corpus will also lie.
94 Lord Phillips stated (at [92]) that the English courts had issued the writ of habeas corpus in two cases "where the defendant had unlawfully removed the prisoner from the jurisdiction and where it was uncertain whether the defendant retained sufficient control over the prisoner to procure his release", referring to Barnardo and O'Brien. In these cases, the "object of the issue of the writ was to put that question to the test". Lord Phillips stated that the principal issue was whether what he called "the O'Brien approach" should be adopted on the facts of the present case.
95 Lord Phillips referred to an "unexplored issue", namely, that no one had suggested that the UK forces acted unlawfully in detaining Mr Rahmatullah in Iraq or in then transferring him to the custody of the United States forces. Putting to one side the unexplored issue, Lord Phillips agreed (at [98]) with the judgment of Lord Kerr JSC.
96 Lord Reed JSC stated (at [108]) that he agreed with the conclusion that the appeal by the Secretaries of State should be dismissed, but he reached that conclusion for reasons that he would express "more narrowly" than Lord Kerr JSC. Lord Reed JSC stated (at [109]-[110]):
109 As Lord Phillips of Worth Matravers has explained, the writ of habeas corpus requires a respondent who is detaining a person ("the prisoner") to produce him before the court and to justify his detention. If the respondent cannot justify his detention of the prisoner, he will be ordered to release him. His failure to comply with such an order will fall within the scope of the court's jurisdiction to deal with contempt. It follows that the appropriate respondent to the writ is in principle the person who has custody or control (or, as it has sometimes been put, actual custody or constructive custody) of the prisoner: that is to say, either the actual gaoler, or some other person who has "such control over the imprisonment that he could order the release of the prisoner": R v Earl of Crewe, Ex p Sekgome [1910] 2 KB 576, 592, per Vaughan Williams LJ. As Scrutton LJ said in R v Secretary of State for Home Affairs, Ex p O'Brien [1923] 2 KB 361, 391, if the court is satisfied that the body whose production is asked is not in the custody, power or control of the person to whom it is sought to address the writ, a writ of habeas corpus is not the proper remedy.
110 Cases can arise in which it is uncertain whether the respondent has sufficient control of the prisoner's detention to be required to justify his detention and to be ordered to release him. In such a case, the court can issue the writ so that it can determine the question of control on the return, with a fuller knowledge of the facts. Barnardo v Ford [1892] AC 326 and Ex p O'Brien are examples.
97 At [112], Lord Reed JSC stated that the Court of Appeal, on the basis of its analysis of the evidence, concluded "that there was sufficient uncertainty to justify the issue of the writ". Lord Reed JSC stated that this appeared to have been a "reasonable conclusion". He then set out the relevant facts that supported that conclusion.
98 Lord Reed JSC stated, at [115], that he considered it important that Mr Rahmatullah was initially detained by British forces, with the consequence that the question was whether the Secretaries of State's control over him had been relinquished. Otherwise, there may be insufficient connection with the jurisdiction. Lord Reed JSC also stated that, like Lord Phillips, he would wish to reserve his opinion on the unexplored issue.
99 Lord Carnwath and Baroness Hale JJSC stated (at [118]) that, on the issue of control, "the effect of the two MoUs concluded in 2003 and 2008 is crucial". They considered it doubtful whether provisions of an international treaty (GC4) could on their own be relied on as giving control for the purposes of the domestic law of habeas corpus. They considered (at [119]) clause 4 of the 2003 MoU to be "crucial" because, on the evidence, "it was designed specifically to ensure that the United Kingdom did retain control over the continuing legality of the detention". They noted (at [120]) the possible issue as to whether the 2008 MoU, which did not contain an equivalent clause, was intended to alter the position in relation to those already detained. They said that the evidence was equivocal on this point and the document did not in terms have that effect. Lord Carnwath and Baroness Hale JJSC stated (at [121]) that they were not unduly concerned by the unexplored issue identified by Lord Phillips and Lord Reed JSC, explaining their reasons for holding that view. Lord Carnwath and Baroness Hale JJSC stated (at [123]):
As to the authorities, we accept of course that there are factual differences from O'Brien, in particular because in that case, unlike the present, the original detention was itself unlawful. However, habeas corpus is equally applicable where detention, originally lawful, later becomes unlawful. It is true also that in this case the illegality of the detention arose through the actions of the US, rather than the UK, and at a time when the UK no longer had actual custody. However, it is difficult to see why this should make a difference in principle. Since illegality of detention is presumed in favour of the applicant, it should not be a defence for the UK to say that it arose from someone else's actions, if the UK has the practical ability to bring it to an end.
100 I note that O'Brien and Rahmatullah were referred to by Gageler J in Plaintiff M68/2015 v Minister for Immigration and Broder Protection [2016] HCA 1; 257 CLR 42 at [165]. His Honour stated:
Amenability to the writ is determined solely as a question of whether the person to whom the writ is addressed has de facto control over the liberty of the person who has been detained, in relation to which actual physical custody is sufficient but not essential.
In support of that proposition, Gageler J cited O'Brien at 391 and 398 and Rahmatullah at [43] and [109].
101 The principles discussed in O'Brien and Rahmatullah were considered by the England and Wales Court of Appeal in C3. STCA submits that aspects of the reasoning of the Court of Appeal express the principles more narrowly than the judgments in Rahmatullah. For present purposes, it is sufficient to focus on the three cases relied on by STCA.
102 I do not consider it necessary to discuss the judgment in Hicks v Ruddock [2007] FCA 299; 156 FCR 574 (Hicks), as this concerned a strike-out application rather than a judgment on whether the writ of habeas corpus should issue.
103 The following propositions emerge from the cases discussed above:
(a) For a defendant or respondent to be amenable to a writ of habeas corpus, actual physical custody of the relevant person is not essential; it is sufficient if the defendant or respondent has control over the detention of the relevant person: O'Brien at 398 per Atkin LJ; Rahmatullah at [43] per Lord Kerr JSC, at [90]-[91] per Lord Phillips of Worth Matravers, at [109] per Lord Reed JSC.
(b) The question whether a defendant or respondent has control over the detention of the relevant person is concerned with whether control exists in fact (as distinct from in law): O'Brien at 398 per Atkin LJ; Rahmatullah at [48] per Lord Kerr JSC.
(c) Control may be established, for example, where there is an agreement or arrangement (whether or not legally enforceable) between the person who is detaining the relevant person and the defendant/respondent whereby the relevant person will be handed over upon demand: O'Brien at 398-399 per Atkin LJ.
(d) If the Court is satisfied that the relevant person is not in the custody or control of a defendant or respondent, a writ of habeas corpus ought not issue: Barnardo at 335 per Lord Watson; O'Brien at 391 per Scrutton LJ; Rahmatullah at [109] per Lord Reed JSC.
(e) Where a defendant or respondent contends that he or she does not have custody or control over the relevant person, and the Court is left in doubt about the matter, it is open to the Court to use the "pressure of the writ" to test whether the defendant's or respondent's contention is correct: Barnardo at 339 per Lord Herschell; O'Brien at 381 per Bankes LJ, at 392 per Scrutton LJ, at 399 per Atkin LJ; Rahmatullah at [45], [60], [63]-[64] per Lord Kerr JSC, [92] per Lord Phillips of Worth Matravers, [110] per Lord Reed JSC.
104 Applying these propositions in the present case, I am satisfied (on the balance of probabilities) that the relevant women and children are not in the custody or control of the respondents.
105 Plainly, they are not in the custody of the respondents; they are in the custody of the AANES and/or the SDF.
106 As for control, there is no agreement or arrangement between the Australian Government and AANES relating to the release or repatriation of the relevant women and children. Thus, the Australian Government does not have the power to effect their release or repatriation. All that the Australian Government has is the ability to request repatriation of the relevant woman and children. While it is likely that any such request will be agreed to by AANES (subject to compliance with procedural requirements), it cannot be assumed that AANES will agree. That is a decision for AANES to make upon receipt of a request. The ability to request the release or repatriation of the relevant women or children, in the absence of an agreement or arrangement that any such request will be agreed to, does not amount to control over the detention of the relevant women and children. For these reasons, in my view, the respondents do not have control over the detention of the relevant women and children. To the extent that the expert evidence expresses a contrary opinion, I do not accept that opinion, for the reasons I have given.
107 The facts of the present case are quite unlike those of Barnardo, O'Brien and Rahmatullah. In Barnardo, Dr Barnardo had previously had custody of the child and it was unclear on the evidence whether he had ceased to have control. In O'Brien, Mr O'Brien had previously been in the custody or control of the Home Secretary and there was evidence that suggested that the Home Secretary retained de facto control. In particular, the order stated that Mr O'Brien was to "be interned in the Irish Free State … and shall remain there until further orders". In Rahmatullah, clause 4 of the 2003 MoU provided that any prisoners of war, civilian internees and civilian detainees transferred by a detaining power (the UK) would be returned by the accepting power (the US) to the detaining power "without delay upon request by the detaining power". This appeared to give the United Kingdom the ability to effect the release of Mr Rahmatullah.
108 I accept that, in some circumstances, where the Court is left in doubt as to whether a respondent has custody or control over the relevant person, it is open to the Court to use the "pressure of the writ" to test whether the respondent's contention (of lack of custody or control) is correct. However, I do not consider this approach to be appropriate in the circumstances of the present case. The question of control has already been the subject of extensive evidence led by both sides. I consider that this evidence makes clear that there is no agreement or arrangement between the Australian Government and AANES regarding release or repatriation of the relevant women and children and that the Australian Government does not otherwise have control over the detention of the relevant women and children. In these circumstances, a further hearing on the return of the writ is not necessary to ascertain the true position or to test whether the respondents' contentions are correct. Therefore, I do not consider the approach adopted in Barnardo, O'Brien and Rahmatullah to be appropriate in the circumstances of this case.
109 Given the above, it is unnecessary to consider the issue of standing (in relation to the relevant women and children who are not STCA Woman and Children).
110 For these reasons, I conclude that a writ of habeas corpus should not issue.
