and
THE SECRETARY OF STATE FOR THE HOME DEPARTMENT
Respondent
Representation :
For the applicant: Mr A. Bandegani, instructed by Wilson Solicitors LLP
For the respondent: Ms E. Wilsdon, instructed by the Government Legal Department
1) The fact that:
(i) the European Convention Against Trafficking in Human Beings ("ECAT") is not a part of domestic law; but
(ii) the Secretary of State for the Home Department has decided to give effect to ECAT by means of a policy,
is not a reason for a court or tribunal to refuse to examine the lawfulness of that policy by reference to the judgments in R (A) v Secretary of State for the Home Department [2021] UKSC 37 ("A") and R (BF Eritrea) v Secretary of State for the Home Department [2021] UKSC 38 ("BF (Eritrea)").
(2) The ECAT and the policy guidance are not to be read together as merely a single policy of the respondent, which may be judicially scrutinised in its entirety and declared unlawful if found in any respect to be internally inconsistent. Despite not being incorporated into domestic law, ECAT is not itself a policy of the respondent, whose terms can be changed or abrogated by her. ECAT remains an international set of obligations. Accordingly, when seeking to establish the appropriate public law mechanism for assessing the lawfulness of the respondent's policy guidance, it is essential to recognise that the respondent has chosen to give ECAT normative effect, with the policy guidance being a set of instructions to her caseworkers on how to make decisions that give effect to ECAT.
(3) This means that the lawfulness of the Secretary of State's policy instructions to caseworkers on how to make decisions that give effect to ECAT falls to be determined by reference to the test (based on Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC 112), which was approved in A and BF (Eritrea), for assessing the lawfulness of policies that give guidance on the meaning and effect of the law; namely, can the policy be operated in a lawful way; or does it impose requirements which mean that a material and identifiable number of cases will be dealt with in an unlawful way?
JUDGMENT
A. INTRODUCTION
1. The applicant is a citizen of Albania. She claims to have arrived in the United Kingdom on 28 March 2014 and was first referred into the respondent's National Referral Mechanism (NRM) on 14 April 2014. The referral resulted in a positive reasonable grounds decision but a negative conclusive grounds decision on the issue of whether the applicant was a victim of modern slavery.
2. The applicant also claimed asylum but that was refused and a subsequent appeal was dismissed.
3. The applicant was again referred to the NRM in May 2016, receiving a positive reasonable grounds decision on 16 June 2016 and, this time, (after judicial review proceedings) a positive conclusive grounds decision on 4 June 2019.
4. On 3 June 2019, the respondent decided not to grant the applicant discretionary leave to remain in the United Kingdom. That decision was, however, challenged and on 25 September 2020, the respondent granted the applicant twelve months' discretionary leave.
5. That decision was itself challenged and on 18 March 2021, the respondent granted the applicant 30 months' discretionary leave. The 30 months were stated to run from the date of the initial grant of discretionary leave on 25 September 2020.
6. The applicant has been diagnosed with complex post-traumatic stress disorder (CPTSD). The International Society for Traumatic Stress Studies guidelines for CPTSD recommend a three-phase approach to treatment, focussing initially on stabilisation through the understanding and control of symptoms, followed by work on processing of traumatic memories and, finally, a phase of social and psychological integration.
7. The decision of 18 March 2021 stated that 30 months' discretionary leave had been granted "to allow [the applicant] to access the 3 phased intervention treatment recommended" in a psychiatric report dated 25 September 2020. The leave was said to have "been granted in accordance with the Modern Slavery DL policy".
8. In response to the earlier decision to grant twelve months' leave, those acting for the applicant had supplied the respondent by letter dated 6 January 2021 with a medical report of Professor Katona. In that report, Professor Katona stated that the three stage treatment process would vary from each person according to their specific mental health needs. In order for therapy to be effective, the "key principle" was that the individual concerned "has sufficient sense of safety and security". Professor Katona considered that the applicant's treatment was likely to take "well over a year from its inception" and that "unlimited leave to remain would make the best clinical sense" for the applicant. The treatment would involve "considerably more than 25 weeks" and the delays in granting her leave, together with the limited nature of the leave, had created uncertainty and continuing fear of returning to Albania, which Professor Katona considered impeded the creation of subjective safety and security for her.
9. The covering letter opined that Professor Katona's report supported the submission on the applicant's behalf that the grant of twelve months was insufficient in her case. The letter also said that the report highlighted a situation "in which there is a failure to consider the individual circumstances of the case in only granting the applicant twelve months' leave to remain, illustrating the unlawful nature of the DLR policy which leads to uncertainty and arbitrary decision-making - rendering the policy unlawful".
B. EUROPEAN CONVENTION AGAINST TRAFFICKING IN HUMAN BEINGS / RESPONDENT'S POLICY: DISCRETIONARY LEAVE CONSIDERATIONS FOR VICTIMS OF MODERN SLAVERY (VERSION 4.0)
10. The applicant's judicial review of the decision of 25 September 2020 became (through the filing of amended grounds on 25 March 2021) a challenge to the decision of 18 March to grant 30 months' leave to remain. It does so by reference to the respondent's policy "Discretionary leave considerations for victims of modern slavery", which is said to be unlawful, in that it fails properly to reflect, or give effect to, the European Convention against Trafficking in Human Beings 2005. This Convention (hereafter ECAT), entered into by the member States of the Council of Europe including the United Kingdom, is an international treaty, which binds this country as a matter of international law. ECAT has not, however, been incorporated by legislation into domestic law.
11. Under Article 12(3) of ECAT, the State must provide necessary medical or other assistance to victims lawfully resident within its territory who do not have adequate resources and need such help. Article 12(5) requires States to take measures, where appropriate and under the conditions provided for by its internal law, to co-operate with non-governmental organisations, other relevant organisations or other elements of civil society engaged in assistance to victims. Article 12(7) requires services to be provided on a consensual and informed basis, taking due account of the special needs of persons in a vulnerable position.
12. For our purposes, the key provision of ECAT is Article 14:-
" Article 14
Residence permit
1. Each Party shall issue a renewable residence permit to victims, in one or other of the two following situations or in both: a the competent authority considers that their stay is necessary owing to their personal situation; b the competent authority considers that their stay is necessary for the purpose of their co-operation with the competent authorities in investigation or criminal proceedings.
2. The residence permit for child victims, when legally necessary, shall be issued in accordance with the best interests of the child and, where appropriate, renewed under the same conditions.
3. The non-renewal or withdrawal of a residence permit is subject to the conditions provided for by the internal law of the Party.
4. If a victim submits an application for another kind of residence permit, the Party concerned shall take into account that he or she holds, or has held, a residence permit in conformity with paragraph 1.
5. Having regard to the obligations of Parties to which Article 40 of this Convention refers, each Party shall ensure that granting of a permit according to this provision shall be without prejudice to the right to seek and enjoy asylum."
13. The Explanatory Report to ECAT has this to say about Article 14:-
"182. The two requirements laid down in Article 14, paragraph 1, for issue of a residence permit are that either the victim's stay be 'necessary owing to their personal situation' or that it be necessary 'for the purpose of their cooperation with the competent authorities in investigation or criminal proceedings'. The aim of these requirements is to allow Parties to choose between granting a residence permit in exchange for cooperation with the law enforcement authorities and granting a residence permit on account of the victim's needs, or indeed to adopt both simultaneously.
183. Thus, for the victim to be granted a residence permit, and depending on the approach the Party adopts, either the victim's personal circumstances must be such that it would be unreasonable to compel them to leave the national territory, or there has to be an investigation or prosecution with the victim co-operating with the authorities. Parties likewise have the possibility of issuing residence permits in both situations.
184. The personal situation requirement takes in a range of situations, depending on whether it is the victim's safety, state of health, family situation or some other factor which has to be taken into account."
14. The respondent's policy guidance "Discretionary leave considerations for victims of modern slavery" has had a number of iterations. The version with which we are concerned is 4.0, published on 8 December 2020.
15. Version 4.0 begins by stating that the policy guidance "explains the circumstances in which it may be appropriate to grant discretionary leave to remain (DL) to individuals confirmed as victims of modern slavery by the National Referral Mechanism (NRM), and the considerations that must be made before such a decision is made." The introduction also states that the policy guidance "deals with extending DL or curtailing leave as necessary".
16. Under the heading "Related external links" there are electronic links to the judgment of the Court of Appeal in PK (Ghana) v The Secretary of State for the Home Department [2018] EWCA Civ 98; [2018] Imm AR 961 and to the "Council of Europe Convention on Action against Trafficking in Human Beings" (i.e. ECAT).
17. At page 5 of 16, the policy guidance states that a person will not qualify for DL solely because a conclusive grounds decision has been made that they are a victim of modern slavery. "There must be reasons based on their individual circumstances to justify a grant of DL". Discretionary leave may be considered where a positive conclusive grounds decision has been made and the person satisfies one of the following criteria:
• leave is necessary owing to personal circumstances,
• leave is necessary to pursue compensation,
• victims who are helping police with their enquiries.
18. The policy guidance then deals, in some detail, with each of those three categories.
19. On page 10 of 16, the policy guidance says that a positive conclusive grounds decision does not result in an automatic grant of immigration leave. However, unless the person concerned has an outstanding asylum claim, automatic consideration (for non-EEA victims) "should normally be given at the same time, or as soon as possible afterwards, to whether a grant of discretionary leave is appropriate under this policy".
20. At page 11 of 16, the policy guidance explains that a person who has been granted DL under the policy and who wishes to extend it for a further period must make an application to the Home Office, using a specified form. "Further periods of DL may be granted where the individual continues to meet the eligibility criteria set out in this policy".
21. On page 12 of 16, we find the following:-
" Requests for indefinite leave to remain
There is no requirement to issue indefinite leave to remain (ILR) to confirmed victims of modern slavery, and the threshold for a grant of ILR outside the Immigration Rules is a high one. Victims of modern slavery granted DL under this policy are not considered to be on a route to indefinite leave to remain in the UK."
22. On page 14 of 16 there is this:-
" Standard grant of leave periods
Where DL under this policy is granted for medical treatment it should normally be for up to 30 months. When the initial leave expires, a further period of leave may be granted on application.
A grant of DL to assist in police enquiries or for the purposes of pursuing a compensation claim should be for the time considered necessary depending on the circumstances, up to a maximum of 12 months in the first instance.
For a longer periods (sic) of DL to be granted there must be sufficient evidence to demonstrate that the individual circumstances of the case can be distinguished to a high degree from other cases.
...
Cases involving children
In cases involving children, the best interests of the child is regarded as a primary consideration. (although not necessarily the only consideration) and one that can affect the duration of leave granted. See section 55 of the Borders, Citizenship and Immigration Act 2009 for further guidance, and Article 14(2) of the Council of Europe Convention on Action against Trafficking in Human Beings.
Where the child or their parent meets the criteria for a grant of DL based on modern slavery, consideration should be given to factors such as the length of residence in the UK, where the child was born, and the strength of the evidence to suggest that the child's life would be adversely affected by a grant of limited leave rather than indefinite leave to remain (ILR). This does not alter the expectation that in most cases a standard period of up to 30 months will be appropriate.
Parents of children granted extended leave must separately demonstrate that there are compassionate factors, in their own right, to warrant departure from the standard grant of DL under this policy. The onus is on the applicant to provide the evidence to support their case."
C. THE APPLICANT'S CHALLENGE
23. The applicant brings three grounds of challenge. The first is that the respondent's DLR policy guidance is unlawful "because it is unclear and too imprecise to form part of a policy capable of being operated lawfully". In particular, it is contended that if "normally" up to 30 months should be granted, it is unclear how a grant of DLR in excess of 30 months can, at the same time, be "standard". Further, it is said to be unclear which "other cases" must be distinguished in order for a longer period of DL to be granted; and what precisely are the circumstances of the relevant other cases that fall to be distinguished. Third, it is said to be unclear what is meant by the threshold for a grant of ILR outside the Immigration Rules being "a high one" and whether and to what extent the criterion is different to the requirement on page 14 of 16 that the case in question must be capable of being distinguished "to a high degree from other cases", in order for a longer period of DLR to be granted.
24. Ground 2 rests on the contention that the purpose of the respondent's policy guidance is to give effect to the United Kingdom's international obligations as a signatory to ECAT. In PK (Ghana), Picken J, at first instance, said it was common ground that the policy guidance "was intended to, and purported to, give effect to the [ECAT]; and that, if it failed to give effect to [ECAT], then that would be a justiciable error of law". Hickinbottom LJ recorded that, before the Court of Appeal " after some consideration and after taking instructions, Miss Bretherton, who also appeared for the Secretary of State below, confirmed that concession" (paragraph 34).
25. In PK (Ghana), the claimant contended that the respondent's policy guidance, as then in force, was inconsistent with Article 14 of ECAT. The guidance stated that the grant of discretionary leave to a victim of trafficking might be appropriate "if their circumstances are compelling".
26. Hickinbottom LJ held that the requirement that the circumstances be "compelling" did not properly reflect Article 14 of ECAT, which provided that the criterion for granting a residence permit was whether the "stay is necessary owing to their personal situation". The court accordingly declared that the relevant policy guidance was unlawful.
27. Ground 2 prays PK (Ghana) in aid. The claimant submits that by "normally" limiting a grant of leave to 30 months, requiring the case to be distinguished to "a high degree" from other cases, when deciding whether to grant longer periods of leave beyond, or towards the top end of, the 30 months; and imposing a "high" threshold where requests for ILR are made, the policy guidance exceeds the requirements of ECAT.
28. Ground 2 also argues that the policy guidance is unlawful (as being contrary to ECAT) because it requires the parents of children who have been granted more than 30 months' leave to show that there are "compassionate factors, in their own right, to warrant departure from the standard grant of DL" for those parents.
29. Ground 3 argues that, in deciding to grant the applicant no more than 30 months' DLR, the respondent failed in her decision dated 19 March 2021 to explain why she had "rejected the opinion of Dr Katona that a longer period of DLR, including ILR, was clinically appropriate and necessary for the purposes of [the applicant's] treatment".
D. THE PROCEEDINGS
30. Permission to bring judicial review proceedings was refused on the papers on 26 April 2021 but granted by Upper Tribunal Judge Allen at a renewal hearing on 19 May 2021.
31. The substantive hearing took place on 17 September 2021. On that date, Counsel informed the Tribunal that Linden J had reserved judgment in a case involving a challenge to the policy guidance, as it bears on recognised victims of trafficking who have made a protection claim and who are not, as a result, removeable from the United Kingdom whilst the claim is undecided and any consequent appeal still pending: sections 77 and 78 of the Nationality, Immigration and Asylum Act 2002. Before Linden J, submissions had been made regarding the status of the concession recorded at paragraph 34 of PK (Ghana); and more generally as to the relationship between ECAT and the policy guidance.
32. Following the handing down of the judgment in Linden J's case ( R (KTT) v Secretary of State for the Home Department [2021] EWHC 2722 (Admin)), we received written submissions on behalf of the applicant (19 October) and the respondent (26 October), and a reply thereto by the applicant (4 November). The Tribunal is grateful to Mr Bandegani and Ms Wilsdon for the high quality of their oral and written submissions.
E. SUPREME COURT JUDGMENTS
33. In order to explain why the relationship between ECAT and the policy guidance has recently become a contentious issue, it is necessary to examine three judgments of the Supreme Court, handed down in 2021.
34. The first is R (SC & Ors) v Secretary of State for Work and Pensions & Ors [2021] UKSC 26. This concerned a judicial review of the so-called two-child limit in respect of child tax credit under the Tax Credits Act 2002 (as amended). It was asserted that the two-child limit unlawfully discriminated against the claimants, contrary to Articles 8/14 of the ECHR, in particular in the light of the United Kingdom's obligations under the United Nations Convention on the Rights of the Child.
35. The Supreme Court held that, whilst the best interests of a child would be a relevant consideration in assessing whether differential treatment was justifiable under Article 8/14, it was not appropriate to seek to apply an unincorporated treaty, such as the Convention on the Rights of the Child, in reaching a determination; or to make a decision whether, in adopting the measure in question, the United Kingdom had complied with its obligations under the Convention. This flowed from the fundamental principle that an unincorporated treaty does not form part of the law of the United Kingdom.
36. The second and third Supreme Court judgments form a pair. They are R (A) v Secretary of State for the Home Department [2021] UKSC 37 and R (BF Eritrea) v Secretary of State for the Home Department [2021] UKSC 38.
37. A concerned a policy known as the Child Sex Offender Disclosure Scheme Guidance. The claimant submitted that the guidance was unlawful, in that it did not make sufficient provision for the police to consult him before making disclosure about his offences to a member of the public who makes enquiry about him in circumstances where the claimant is in contact with children. The claimant was a convicted sex offender.
38. The judgment of Lord Sales and Lord Burnett noted that policies "are different from law" but that, in the last decades, "the courts have given policies greater legal effect". In a parallel development "there has been an increase in judicial review of the contents of policies" (paragraphs 3 and 4).
39. In A, the Supreme Court affirmed the importance of the decision of the House of Lords in Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC 112. This concerned Department of Health and Social Security guidance to health authorities on family planning services, including a section on contraceptive advice and treatment for young people. The claimant sought a declaration that the guidance gave advice which was unlawful and wrong. She succeeded in the Court of Appeal on the grounds that a girl under 16 was incapable either of consenting to treatment or of validly requiring a doctor not to seek the consent of her parents; and that the guidance was contrary to law, in that any doctor who treated a girl under 16 without such consent, other than in an emergency, would be infringing her parents' rights (paragraph 30). The House of Lords reversed the decision of the Court of Appeal.
40. At paragraph 34, the Supreme Court noted that Lord Scarman, in Gillick, made explicit "that it was not the role of policy guidance to eliminate all uncertainty regarding its application and all risk of legal errors by doctors". The policy was "to be read objectively, having regard to the intended audience". The drafter of a policy was "not required to imagine whether anyone might misread the policy and then to draft it to eliminate that risk". Rather, it was "only if the guidance, on a reasonable reading of it, positively encouraged a doctor to think that he was authorised to prescribe without the parent's consent whenever he thought fit that it would be unlawful".
41. Of particular relevance are the following passages from the Supreme Court's judgment:-
...
...
47. In a category (iii) case, it will not usually be incumbent on the person promulgating the policy to go into full detail about how exactly a discretion should be exercised in every case. That would tend to make a policy unwieldy and difficult to follow, thereby undermining its utility as a reasonably clear working tool or set of signposts for caseworkers or officials. Much will depend on the particular context in which it is to be used. A policy may be sufficiently congruent with the law if it identifies broad categories of case which potentially call for more detailed consideration, without particularising precisely how that should be done. This was the approach adopted by Green J in R (Letts) v Lord Chancellor (Equality and Human Rights Commission intervening) [2015] EWHC 402 (Admin); [2015] 1 WLR 4497 (' Letts').
...
63. We agree that this is a fundamental distinction for the purposes of analysis. If it is established that there has in fact been a breach of the duty of fairness in an individual's case, he is of course entitled to redress for the wrong done to him. It does not matter whether the unfairness was produced by application of a policy or occurred for other reasons. But where the question is whether a policy is unlawful, that issue must be addressed looking at whether the policy can be operated in a lawful way or whether it imposes requirements which mean that it can be seen at the outset that a material and identifiable number of cases will be dealt with in an unlawful way.
65. First, it is unclear what the relationship of such a principle is with the authoritative guidance given in Gillick. If the principle were that a policy is unlawful if it creates an unacceptable risk that an individual will be treated unlawfully, that is a substantially wider principle than that stated in Gillick and inconsistent with it. There is no sound conceptual basis for separating out unlawfulness due to unfairness from unlawfulness for any other reason. Secondly, a test whether a policy creates an "unacceptable risk" that an individual will be treated unfairly or unlawfully provides no criterion of what makes a risk count as unacceptable. The distinction drawn in Tabbakh between whether a policy is inherently unfair or it just leaves a risk of unfairness arising in the ordinary course of individual decision-making is similarly unclear. A determinate criterion is required to distinguish the two cases in a principled way. Gillick supplies it. Thirdly, a test for the lawfulness of a policy based on "unacceptable risk" or the like would be a new departure in public law and cannot be regarded as an incremental extension from existing principle. On the contrary, as we have explained, in our opinion it would subvert existing principle. By contrast, if the test of inherent unfairness is applied by reference to the principle in Gillick, the law supplies a reasonably clear criterion of unlawfulness which has a sound foundation in principle. Fourthly, without such a foundation, the assertion of such a power of review by the courts, in relation to functions (the operation of administrative systems and the statement of applicable policy) which are properly the province of the executive government would represent an unwarranted intrusion by the courts into that province. Anchoring the lawfulness of policy to the principles articulated in Gillick avoids that outcome. Fifthly, if one moves away from that principled foundation, there is a risk that a court will be asked to conduct some sort of statistical exercise to see whether there is an unacceptable risk of unfairness, as was urged upon the court in the BF (Eritrea) appeal: see our judgment in BF (Eritrea) at paras 35 and 41. But a court is not well equipped to undertake such an analysis based upon experience. In principle, the test for the lawfulness of a policy should be capable of application at the time the policy is promulgated, which will be before any practical experience of how it works from which statistics could be produced. The test for the lawfulness of a policy is not a statistical test but should depend, as the Gillick test does, on a comparison of the law and of what is stated to be the behaviour required if the policy is followed. Both aspects of this test are matters on which the court is competent and has the authority to pronounce."
42. At paragraph 74, the Supreme Court disapproved of the judgment of the Divisional Court R (W) v Secretary of State for the Home Department [2020] EWHC 1299 (Admin), which held that a policy would be unlawful "if it leads to unlawful results in 'a significant number of cases'", as well as the test derived from the Court of Appeal judgment in BF (Eritrea) that "policy guidance would be unlawful if there is 'a real risk of the guidance leading to an unlawful result in a more than minimal number of cases'".
43. In BF (Eritrea), handed down on the same day as A, the Supreme Court relied upon its judgment in that case to overturn the majority judgment of the Court of Appeal which had held that the respondent's policy guidance for Immigration Officers, assessing whether an asylum seeker appears to be a child, was unlawful.
44. In BF (Eritrea), the policy guidance was issued in the light of paragraph 16(2A) of Schedule 2 to the Immigration Act 1971. This introduced restrictions on the place and duration of immigration detention, in the case of an unaccompanied child. Applying the " Gillick principle", the Supreme Court held:-
F. THE RELATIONSHIP BETWEEN ECAT AND THE POLICY GUIDANCE
45. We have already noted the "concession" in PK (Ghana). Earlier, a similar concession was recorded by the Divisional Court in R (Atamewan) v Secretary of State for the Home Department [2014] 1 WLR 1959. Aikens LJ noted the following:-
46. At paragraph 69, the Divisional Court held, in terms, that the guidance "purports to set out [UK government policy] in a manner consistent with the provisions of the [ECAT]".
47. In R (Galdikas) v Secretary of State for the Home Department [2016] 1 WLR 4031, Sir Stephen Silber (who had been part of the Divisional Court in Atamewan) held at paragraphs 48 to 52 that he was not bound by the concession made by Mr Eadie QC in Atamewan. This was because the concession had been made "at least in" the Divisional Court and in any event had merely been assumed to be correct. Sir Stephen therefore determined the issue himself, holding that it was, indeed, the policy of the respondent to apply ECAT when considering applications for discretionary leave to remain (paragraph 65).
48. The respondent's position before us was, broadly, the same as her position had been before Linden J; namely, that the Supreme Court judgment in SC means that so much of the concessions as concern the justiciability of challenges brought by reference to ECAT must no longer be relied upon. Linden J rejected that argument (paragraph 52).
49. At this point, we first encounter the question of whether the Upper Tribunal should follow the legal findings of Linden J. As explained in Willers v Joyce (No 2) [2016] UKSC 44, puisne judges are not technically bound by decisions of their peers, but should generally follow a decision of a court of co-ordinate jurisdiction, unless there is a powerful reason for not doing so (paragraph 9). The same approach has been taken by the Upper Tribunal, in relation to decisions of the High Court: The Kingsbridge Pension Fund Trust v Downs [2017] UKUT 237 (LC).
50. On the "justiciability" issue, we are in no doubt that there is no "powerful reason" for us to decline to follow Linden J. Not only is his decision, with respect, not plainly wrong; it is manifestly correct. The respondent has greatly over-stated the significance of the judgment in SC, as it bears on the issues with which we are concerned.
51. We have seen that the concession in Atamewan was made expressly on the basis that ECAT had not been transposed into domestic law and therefore did not have "direct effect". Neither the parties nor the Divisional Court were under any misapprehension in that regard. The principle that an international treaty needs to be incorporated by domestic legislation in order to have direct effect has been part of our law since at least the judgment of the House of Lords in JH Rayner (Mincing Lane) Ltd v Department of Trade and Industry [1990] 2 AC 418.
52. In similar vein, Sir Stephen Silber at paragraph 61 of Galdikas was fully alive to the significance of ECAT being "an unimplemented treaty". He could see no reason why the respondent could not, nevertheless, adopt a policy based wholly or partly on such a treaty.
53. We also see no reason to depart from the conclusion of Linden J that the concession recorded in PK (Ghana) formed part of the Court of Appeal's ratio in that case and was not merely assumed by the Court of Appeal to be correct (paragraphs 53 to 59).
54. Nevertheless, the fact that the respondent may, in the past, have had a policy to give effect to ECAT in the United Kingdom, by means of her own policy guidance to caseworkers, does not mean that she must continue indefinitely to do so. Since ECAT has no independent normative status, the respondent could adopt a policy that, henceforth, she will not seek to give effect to ECAT (regardless of her international obligations), when making decisions concerning modern slavery; or that she will give effect to some provisions of ECAT, but not others.
55. As it had been before Linden J, the respondent's position before us on this issue was somewhat puzzling. Her position caused Linden J to undertake a detailed analysis of version 4 of the policy guidance and its predecessors, in order to determine whether, as matter of interpretation, the policy guidance does currently have the purpose of guiding caseworkers to make decisions that are in accordance with ECAT.
56. In carrying out this analysis, Linden J observed that, under the section of the policy guidance headed "Related external links", there are hyperlinks both to PK (Ghana) and to the ECAT. He also observed that, in the policy guidance, the three categories of case where discretionary leave (DL) may be considered precisely mirror the three categories arising from Article 14.1 of ECAT; namely, personal circumstances, pursuing compensation (like personal circumstances, an aspect of "personal situation" in Article 14.1(a)) and helping police with their enquiries (paragraphs 71 to 76). At paragraph 77, he noted the statement of Mr Tam QC on behalf of the respondent that the respondent's policy was to comply with ECAT. Linden J held that it "would therefore be surprising if, exceptionally, the intention was that ECAT did not apply under [the policy guidance]" (paragraph 77).
57. All this led Linden J to conclude at paragraph 79 that the policy guidance "overwhelmingly demonstrates a commitment to take decisions as to discretionary leave in accordance with ECAT albeit, for reasons which I will explain, the requirements of Article 14 have not been fully appreciated".
58. Before us, Ms Wilsdon advanced no submissions on this issue that had not, in substance, featured before Linden J. We see no reason to depart from his finding that, as was the position with its predecessors, version 4.0 of the policy guidance is intended to guide the respondent's caseworkers to take decisions which are in accordance with ECAT. Like Linden J, we do not find that there is any reason to conclude that the respondent's policy is to implement some, but not all, of the provisions of ECAT.
G. DETERMINING THE LEGALITY OF THE POLICY GUIDANCE
59. In KTT, Linden J, having reached the conclusion that the Secretary of State's policy was to take decisions as to discretionary leave in accordance with ECAT, went on to consider the correct interpretation of Article 14(1)(a) of ECAT, as it bore on the question before him. As we have seen, this question was whether KTT's stay in the United Kingdom, in order to pursue a claim for international protection based on her fear of re-trafficking, meant that it was "necessary" for her to be issued a residence permit, in order to comply with Article 14; or whether the statutory provisions that precluded her from being removed from the United Kingdom meant such a permit was unnecessary. Linden J addressed this "interpretation" issue, beginning at paragraph 81 of his judgment.
60. With one proviso, we agree with Ms Wilsdon that Linden J's findings on the "interpretation" issue have no material bearing on the decision we must reach in the present judicial review. The proviso concerns the way in which a domestic court or Tribunal should interpret ECAT. In Nautical Challenge Ltd v Evergreen Marine (UK) Ltd [2021] 1 WLR 1436, the Supreme Court held, at paragraph 38, that international conventions should be interpreted by reference to "broad and general principles of construction rather than any narrower domestic law principles". Those general principles include the general rule of interpretation, set out in Article 31.1 of the Vienna Convention on the Law of Treaties 1969. This provides that a treaty shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of the treaty's object and purpose.
61. We agree with Linden J that we should follow that approach in construing ECAT, in order to decide whether the Secretary of State's policy guidance on a further grant of discretionary leave, requests for indefinite leave to remain and standard grant of leave periods, is unlawful.
62. Let us take stock. We have concluded that the policy of the respondent is to give effect to ECAT; and that the policy guidance is to be interpreted as the mechanism by which the respondent seeks to do so. This is the basis on which we must decide the specific challenge brought by the claimant against the policy guidance.
63. In doing so, it seems to us that the Supreme Court judgments in A and BF (Eritrea) affect the way in which the concessions in Atamewan and PK (Ghana) - and the corresponding finding of Sir Stephen Silber in Galdikas - fall to be understood.
64. The Supreme Court judgments in A and BF (Eritrea) concern policies which, in some way or other, relate to provisions of domestic law. At paragraph 46 of the judgment in A, the Supreme Court identified three categories of case where a policy may be found to be unlawful by reason of what it says or omits to say about that law, when giving guidance for others. The third category is:-
"Where the authority, even though not under a duty to issue a policy, decides to promulgate one and in doing so purports in the policy to provide a full account of the legal position but fails to achieve that, either because of a specific misstatement of the law or because of an omission which has the effect that, read as a whole, the policy presents a misleading picture of the true legal position."
65. Where the Secretary of State issues guidance to her own staff explaining the legal framework in which they perform their functions, the Supreme Court held that the context is likely to be such as to bring it within that third category:-
"The audience for the policy would be expected to take direction about the performance of their functions on behalf of their department from the Secretary of State at the head of the department, rather than seeking independent advice of their own. So, read objectively, and depending on the content and form of the policy, it may more readily be interpreted as a comprehensive statement of the relevant legal position and its lawfulness will be assessed on that basis."
66. As we have seen, the Supreme Court's test for assessing lawfulness, based on Gillick, is whether the policy could be operated in a lawful way or whether it imposes requirements which mean that a material and identifiable number of cases will be dealt with in an unlawful way. As the court said at paragraph 41, if the policy directs its audience to act in a way that contradicts the law, it is unlawful. The courts are well-placed to make a comparison of normative statements in the law and in the policy, objectively construing both.
67. The test does not, however, depend on a statistical analysis of the extent to which relevant actors might or might not fail to comply with their legal obligations. For this reason the Supreme Court rejected the higher threshold, by which a policy's lawfulness is to be judged by reference to whether there is an unacceptable risk that an individual would be treated unlawfully: paragraphs 63 to 65; and paragraph 74, disapproving the test adopted in R(W) of whether there is a "real risk of unlawful outcomes in a 'significant' or 'more than minimal' number of cases".
68. In the present case, of course, ECAT is not a part of domestic law. We do not, however, consider that this is a valid reason for failing to examine the lawfulness of the respondent's policy guidance through the lens of A and BF (Eritrea). It would be strange if the very fact that ECAT does not have an independent normative quality were to result in the policy guidance being subjected to a higher degree of public law scrutiny, than would be the case if ECAT did have independent legal force.
69. At paragraph 78 of KTT, Linden J recorded that:-
"There was an interesting discussion at the Hearing as to whether it made a difference if the treaty was written out in full in the form of a policy document, at one extreme, or simply stated that the policy of the government was that decisions as to discretionary leave would be taken in accordance with ECAT, on the other. My view is that the form does not matter. What matters is the question whether the stated policy conveys to the reasonable reader that this is the approach which will be taken."
70. For the purposes with which Linden J was concerned at that point of his judgment, the question of form did not matter. Linden J was at that point considering whether a legal connection between ECAT and the policy guidance was established. He held that it was; and we respectfully agree.
71. In order to decide the nature of the legal relationship between ECAT and the policy guidance, the question is, however, important. The ECAT and the policy guidance are not to be read together as merely a single policy of the respondent, which may be judicially scrutinised in its entirety and declared unlawful if found in any respect to be internally inconsistent. Despite not being incorporated into domestic law, ECAT is not itself a policy of the respondent, whose terms can be changed or abrogated by her. ECAT remains an international set of obligations. Accordingly, when seeking to establish the appropriate public law mechanism for assessing the lawfulness of the respondent's policy guidance, it is essential to recognise that the respondent has chosen to give ECAT normative effect, with the policy guidance being a set of instructions to her caseworkers on how to make decisions that give effect to ECAT.
72. For these reasons, we find that the lawfulness of the policy guidance falls to be determined according to the principles set out in A and BF (Eritrea). This does not, of course, mean that earlier decisions, in particular PK (Ghana), were wrong. In PK (Ghana) by directing her caseworkers to ask whether a victim's circumstances were "compelling", instead of whether they were such as to make it "necessary" to grant discretionary leave, the respondent plainly fell foul of the Gillick test, as articulated and explained by the Supreme Court.
H. DECIDING THE GROUNDS
73. We can now turn to the applicant's grounds of challenge.
Ground 1
74. As we have seen, ground 1 asserts that the respondent's policy guidance is unlawful because it is unclear and imprecise, as regards the length of DL, when granted for the purpose of enabling the individual to receive medical treatment. In oral submissions, Mr Bandegani informed us that this ground was no longer being advanced as a free-standing ground of challenge. Indeed, Mr Bandegani said that the thrust of the applicant's criticism of the policy guidance was not that it was too vague but, rather, that it was too detailed; and that its detail was incompatible with ECAT.
75. For completeness, however, we record that we in any event reject ground 1. The ground is fundamentally inconsistent with the points made by the Supreme Court at paragraph 47 of A. The present case is, in reality, a "category (iii) case", as described in paragraph 46, with the result that the Supreme Court's observations at paragraph 47 apply: there is no requirement for the policy guidance "to go into full detail about how exactly a discretion should be exercised in every case."
Ground 2
76. Ground 2 seeks, in effect, to align the applicant's present challenge with that of the claimant in PK (Ghana). Just as the Court of Appeal held that the use of "compelling" constituted a materially different test from that contained in ECAT, based on whether a person's stay is "necessary", the applicant submits that instructing caseworkers "normally" to limit a grant of DL to (at most) 30 months places a presumptive cap on the duration of leave. The requirement for caseworkers to distinguish individual circumstances to a "high degree" from other cases, when deciding whether to grant longer periods of leave beyond or towards the top end of the "up to 30 months" of DLR is, likewise, unlawful; as is the imposition of a "high" threshold where requests are made for indefinite leave to remain. Finally, the "expectation" in cases involving children of DLR up to 30 months with a "separate" requirement on parents who wish to secure a longer period of leave is also unlawful. In all these respects, Mr Bandegani says that the relevant passages of the policy guidance do precisely what the Court of Appeal in PK (Ghana) held that the respondent could not do; namely, exceed the requirements of ECAT.
77. There are a number of problems with ground 2. First, there is no evident incompatibility of terminology, as between the policy guidance and ECAT, as there was between the former policy guidance's use of "compelling" and ECAT's use of "necessary". The second problem stems from the first. Unlike PK (Ghana) and KTT, the present challenge does not concern the core question of whether a residence permit (here, DL) should be granted. We are concerned with the length of the residence permit/DL. But ECAT has nothing to say about the length of any residence permit, other than that it must be "renewable" (Article 14.1), which is a point in favour of the respondent, as it suggests that an initial residence permit may well not be coterminous with the period of stay which is "necessary owing to [the individual's] personal situation".
78. Paragraph 182 of the Explanatory Report also assists the respondent. As we have seen, this makes it plain that a residence permit may be issued either on the basis that the victim's stay is "necessary owing to their personal situation" or that it is necessary "for the purpose of their co-operation with the competent authorities in investigation or criminal proceedings". Paragraph 182 says that the aim of these requirements "is to allow Parties to choose between granting a residence permit in exchange for co-operation with the law enforcement authorities and granting a residence permit on account of the victim's needs, or indeed to adopt both simultaneously". It would, therefore, be permissible for the respondent to grant a period of leave by reference to the victim's anticipated co-operation with the police (Article 14.1(b)), even where the victim's mental or physical health needs would point to the necessity of them being granted a longer period of leave under Article 14.1(a).
79. In the light of this, the applicant faces a serious problem in contending that the language of the policy guidance is unlawful. Even adopting the required purposive construction of ECAT, there is no clear linkage between what is "necessary" to trigger the obligation to grant a residence permit and the duration of any such permit. This means that signatory States have at least a significant measure of discretion in determining the duration of such permits. That, in turn, makes it difficult to say the wording of the policy guidance is such as to lead to a material and identifiable number of cases being dealt with "unlawfully" by caseworkers, in the sense of being incompatible with ECAT.
80. Even if the test of necessity is to be followed when caseworkers are deciding upon the duration of DL, we consider that the language used in the policy guidance is unexceptionable. The first point to notice is that on page 11 of 16, under the heading "Further grants of discretionary leave", appropriate provision is made for further periods of DL to be granted "where the individual continues to meet the eligibility criteria set out in this policy". As we have already noted by reference to paragraph 182 of the Explanatory Report, the eligibility criteria do not have to be addressed simultaneously. In any event, the policy guidance imposes no threshold for granting further leave. All that is required is for the individual to meet the relevant criteria, which, in the case of Article 14.1(a), will be that it "is necessary owing to their personal situation".
81. On page 12 of 16, under the heading "Requests for indefinite leave to remain", the policy guidance says that the threshold for a grant of ILR outside the Immigration Rules "is a high one". That is entirely correct, as a matter of fact. Indefinite leave to remain stands at the apex of the forms of leave that can be granted under the Immigration Acts. Even where leave is granted in response to an individual's rights under the ECHR, it is normally limited in nature, albeit renewable and with the potential to lead to ILR in due course.
82. The policy guidance is, at this point, doing no more than alerting caseworkers to the obvious fact that there needs to be a cogent reason to grant ILR to a person whose eligibility for any form of leave to remain will often depend solely upon Article 14 of ECAT. If the position were otherwise, ECAT would make major inroads into the competence of signatory States in the immigration field. Particularly in view of what we have held at paragraphs 77 and 78 above, we do not find that the signatories to ECAT intended such a result. We shall have more to say on this issue at paragraph 88 below.
83. On page 14 of 16, under the heading "Standard grant of leave periods", it is stated that where DL is granted for medical treatment, this should normally be for up to 30 months; although when the initial leave expires, a further period of leave may be granted on application. This paragraph is immediately followed by one which says that in the case of assisting police enquiries, or for the purposes of pursuing a compensation claim, leave should be for the time considered necessary depending on the circumstances, up to a maximum of twelve months in the first instance. As we have explained, the effect of paragraph 182 of the Explanatory Report is such that it would in theory be perfectly possible for the respondent to decide to grant twelve months' leave, for the purposes of assisting police enquiries, even though the individual concerned required medical treatment, which could have resulted in up to eighteen months' more leave being granted.
84. Even on its own terms, the first paragraph, concerning medical treatment, is in any case lawful. Bearing in mind that we are concerned with a policy, there is no material difficulty with the concept of DL being granted "normally ... for up to 30 months". Where the evidence indicates a need for medical treatment of, for example, twelve months, the policy permits twelve months' leave to be granted.
85. The third paragraph, which is common to both the medical treatment and police/compensation categories, provides that for longer periods of DL to be granted there must be sufficient evidence to demonstrate that the individual circumstances of the case "can be distinguished to a high degree from other cases".
86. Mr Bandegani strongly attacked this particular phrase. Again, however, what the applicant must show is whether the phrase is such that a material and identifiable number of cases will be dealt with unlawfully by the caseworkers operating by reference to it. In this regard, it must be remembered - as the applicant was at pains to point out - that the policy guidance contains a hyperlink to ECAT. Caseworkers can, therefore, be expected to be conversant with Article 14, when making decisions as to the length of DL.
87. Unlike the case in PK (Ghana), there is, here, no requirement to apply a test which is plainly incompatible with the language of ECAT. The phrase needs to be read in the light of the fact that the initial period of DL in medical treatment cases can, normally, be up to 30 months; and that further periods of DL can be granted where the relevant eligibility criteria continue to exist.
88. Once these points are grasped, it can be seen that the phrase "distinguished to a high degree...", like the phrase "is a high one" in the passage concerning ILR, does no more than to indicate to the caseworker that there needs to be a good reason before granting a longer period than 30 months. Importantly, the words do not require the caseworker to find that the longer period of stay has to be shown to be more than merely "necessary owing to [the individual's] personal situation". Rather, the words require a careful examination of the relevant circumstances, so as to ensure that the longer period really is "necessary".
89. This leads to the final aspect of ground 2, concerning the grant of leave to parents of children. So far as concerns children themselves, the policy guidance is plainly free from difficulty. Specific reference is made to the section 55 duty to make the child's best interests a primary consideration. There is also a specific reference at this point to Article 14.2 of ECAT. The best interests consideration can lead to a decision that the child should be granted ILR, albeit that "the expectation [is] that in most cases a standard period of up to 30 months DL will be appropriate".
90. The next paragraph of the policy guidance, beginning "Parents of children granted extended leave ..." is likewise unexceptionable in requiring the parent to demonstrate factors in their own right to warrant departure from the standard grant of DL. The description of these factors as "compassionate" is no way comparable to the use of "compelling" in the former guidance, which troubled the Court of Appeal in PK (Ghana). As with cases not involving children, the language on page 15 of 16 of the policy guidance cannot reasonably be read as an instruction to caseworkers to do anything which is contrary to Article 14.1 or 14.2 of ECAT. On the contrary, the language is intended to assist the caseworker to assess the very different types of case that fall to be determined under the overarching test of necessity. It must also be remembered that the parent (as opposed to the child) may not be a victim of modern slavery.
91. Ground 2 accordingly fails.
Ground 3
92. Ground 3 is now confined to the proposition that the respondent was obliged to explain why she rejected the opinion of Professor Katona that a longer period of DLR, including ILR, was clinically appropriate and necessary for the purposes of treatment.
93. We do not find that this ground is made out. The letter of 6 January 2021 from the applicant's solicitors, which enclosed the report from Professor Katona, set out at paragraph 2 a series of findings by the Professor. As we have seen, these included, but were by no means limited to, the finding that unlimited leave to remain "would make the best clinical sense" and that treatment for CPTSD can only take place "if the individual has a sufficient sense of security". Significantly, paragraph 3 of the letter said that it was "clear that the findings in Professor Katona's report clearly support our submission that the grant of 12 months is insufficient in the applicant's individual case". It was not suggested by the solicitors that anything in Professor Katona's report meant that only the grant of indefinite leave to remain constituted what was "necessary" owing to the applicant's "personal situation". That was unsurprising, given the terms of Professor Katona's comments on ILR, which did not contend that nothing less than ILR was "necessary", merely that it was desirable or optimal. In short, read overall, the letter was effectively contending that the grant of twelve months leave would be legally insufficient; nothing more.
Against that background, there is nothing unlawful in the terms of the decision letter. As we have already set out, this stated that a total of 30 months' leave had been granted "to allow your client to access the 3 phased intervention treatment recommended" in the preliminary psychiatric report of 25 September 2020. The timescale in that report would be covered by the grant of 30 months' leave. In the circumstances, the decision letter did not need to engage with Professor Katona's view that indefinite leave to remain would make the best clinical sense.
