Summary of Facts

The Cross-Appellant and Respondent, Ms Begum, was born in the United Kingdom (‘UK’) in 1999 and possessed both British and Bangladeshi citizenship. At age 15, she was said to travelled to Syria to marry an ISIL fighter. In 2019, while detained in a camp, she was deprived of her British citizenship by the Home Office on the grounds that she posed a threat to national security. She made an application for leave to enter the UK, including on the basis that she could not have a fair and effective appeal from a deprivation decision from outside the UK. This application was denied in June 2019. She then appealed the refusal of leave to enter the country to the Special Immigration Appeals Commission (‘SIAC’), which held that the deprivation decision did not make Ms Begum stateless, and that the Secretary of State does not deprive individuals who are outside the UK of British citizenship when that would lead to a real risk of violation of Articles 2 and 3 of the European Convention on Human Rights (‘ECHR’) if they were within the UK’s jurisdiction, and dismissed Ms Begum’s appeal. On appeal, the Divisional Court ordered the Secretary of State to grant Ms Begum leave to enter the UK and grant her the necessary travel documents. The Home Secretary appealed to the Supreme Court, and Ms Begum submitted a cross-appeal.

Throughout the proceedings, Ms Begum remained located in the Al-Roj camp for internally displaced persons in Syria.

Legal Arguments

Legal arguments by the Appellant

The Secretary of State appealed to the Supreme Court on the basis that the Divisional Court was wrong to conclude that SIAC had erred by applying principles of administrative law.
In relation to the leave to enter, the Home Secretary argued that the Court of Appeal was wrong in concluding that Ms Begum should be granted leave to enter the UK on the basis that the right to fair trial could not otherwise be respected.

Legal arguments by the Cross-Appellant and Respondent

Ms Begum argued that her appeal against the deprivation decision should automatically be allowed if it could not be fairly and effectively pursued as a consequence of the refusal of her application for leave to enter the UK (paragraph 13). This was connected to the fact that Ms Begum was at the Al-Roj camp in Syria and thus had sought leave to enter the UK in order to be able to participate effectively in her appeal against the deprivation decision (paragraph 26).

Outcome

The Supreme Court held that the Court of Appeal misunderstood the scope of an appeal against a decision of the Secretary of State to refuse a person leave to enter the UK, as the scope is confined to assessing if the decision is in accordance with Section 6 of the Human Rights Act. As Ms Begum did not advance that argument before the Court of Appeal, her appeal should have been dismissed (paragraph 133). The Supreme Court further held that the assessment of national security requirements is the responsibility of the Home Secretary and the Court of Appeal should not have made an assessment (paragraph 134).

The fact that the appeal process safeguarded against unfairness did not mean that a decision which could not be the subject of an effective appeal was unfair. Parliament had not stipulated what an appellate tribunal should do if a person's circumstances were such that they could not effectively exercise their right of appeal. It would be unjust to a respondent if an appeal were to be allowed merely because an appellant found themselves unable to present their appeal effectively (paragraph 90). The Supreme Court acknowledged that ‘a deprivation decision may have serious consequences for the person in question: although she cannot be rendered stateless, the loss of her British citizenship may nevertheless have a profound effect upon her life’, but that setting aside a deprivation decision could also have serious consequences for the public interest (paragraph 94).

It was held that the right to a fair hearing does not prevail over requirements of national security. If a vital public interest makes it impossible for a case to be fairly heard, then the courts cannot ordinarily hear it. The appropriate response to the problem in the present case is for the deprivation appeal to be stayed until Ms Begum is in a position to play an effective part in it without the safety of the public being compromised (paragraph 135).

The Supreme Court held that the Court of Appeal mistakenly treated the Secretary of State’s extraterritorial human rights policy as if it were a rule of law, as opposed to something intended to guide the exercise of his statutory discretion. Unless there is an issue as to whether the Secretary of State has acted in breach of his obligations under the Human Rights Act, SIAC is confined to reviewing the Secretary of State’s decision by applying essentially the same principles that apply in administrative law. The Secretary of State had had to assess the degree of risk that the respondent would be exposed to mistreatment as a result of the deprivation of her British citizenship while in Syria, and that any potential risks in countries outside Syria were not a foreseeable consequence of the deprivation decision. Having considered the evidence before him, the Secretary of State was not satisfied that the deprivation decision would expose her to a real risk of such mistreatment. SIAC decided that that conclusion was not unreasonable. There was no defect in SIAC’s reasoning in that regard (paragraphs 130, 136).

The Supreme Court unanimously allowed the Secretary of State’s appeals and dismissed Ms Begum’s cross-appeal. Ms Begum’s appeal and judicial review against the decision for leave to enter, and her application for judicial review of SIAC’s preliminary decision in the deprivation appeal, were all dismissed (paragraph 137).

• The case note emphasises that the decision of the Court reflects the fact that the Section 40(2) of the British Nationality Act 1981 gives very wide provision to the SSHD. The author notes that the Court made no comment on whether the current domestic laws prevent arbitrary deprivation of nationality as recognised under the ECHR and international law. The author also raises the issue of the absence of protection from serious harms which, given the technical nature of the definition of statelessness, may not be addressed by protection against statelessness.

Saeed Bagheri and Alison Bisset, ‘International Legal Issues Arising from Repatriation of the Children of Islamic State’ (2022) 27(3) Journal of Conflict and Security Law 363

• This article uses the case of Begum to highlight how the bond between nationality and the right to return can become problematic where there is a threat to national security involved. It expands on this point by mentioning that states often utilise legal mechanisms to strip nationals associated with Islamic State of their nationality. The authors point out ths is contrary to calls from the UN Secretary General for states to accept the repatriation of their nationals.

Ayesha Riaz, ‘Increasing the Powers of the Secretary of State for the Home Department to Strip Individuals of their British Citizenship: R (on the application of Begum) v SSHD’ (2023) 86(6) The Modern Law Review 1517

• The author argues that the Begum decision significantly restricts the role of appellate tribunals, limiting their ability to exercise independent judgment in citizenship deprivation cases and effectively giving the SSHD’s wide discretionary powers even outside the national security context.
• The article suggests that the Supreme Court’s approach demonstrates extreme judicial deference to the executive on national security grounds, raising concerns about the erosion of separation of powers and the ability of courts to provide meaningful oversight of deprivation decisions.
• Recent legal changes under the Nationality and Borders Act 2022 exacerbate these issues by allowing the SSHD to strip individuals of citizenship without notice, creating risks of unfairness, potential breaches of international law (including the 1961 Statelessness Convention), and disproportionate impacts on dual nationals or individuals from migrant communities.

Edward Arash Abedian, ‘The Begum Question: The Scope of Deprivation of Citizenship Appeals in Cases of Fraud’ (2023) 28(3) Judicial Review 164

• The central question the author raises in this article is whether the principles from this case (deference to the SSHD on discretion and limited review) should also govern appeals in fraud cases under s 40(3) of the British Nationality Act 1981.
• The Court of Appeal has so far avoided deciding this question directly, leaving uncertainty about whether tribunals should conduct full merits review or a more limited public-law review in fraud cases.
• The author notes that a merits-based review in fraud cases could be justified because DHSS’s expertise in assessing national security risks does not necessarily translate to fraud assessments
