D8 v Secretary of State for the Home Department
Factual and Procedural Background
This appeal concerns the Secretary of State's challenge to a decision by the Special Immigration Appeals Commission ("SIAC") that the revocation of the Respondent's refugee status and refusal of a further refugee status application on national security grounds were unlawful. SIAC held that although the Secretary of State deemed the Respondent a danger to national security, she failed to carry out a balancing exercise weighing the danger against the cost, practicability, and feasibility of measures to mitigate the risk, and failed to demonstrate that revocation was a last resort.
The Respondent, an Iranian national of Kurdish ethnicity and Sunni Muslim faith, arrived clandestinely in the United Kingdom in 2016 and was granted refugee status in 2017 following a successful appeal. In 2020, the Respondent travelled to the Kurdish region of Iraq and was found to have been in Iran for a period in 2020. The Secretary of State excluded the Respondent from the UK on national security grounds related to Islamist sympathies and support for Islamic State, revoking refugee status in October 2020. The Respondent later returned illegally to the UK in 2021, claimed asylum, which was refused on national security grounds in 2022. SIAC found that the Secretary of State had failed to prove the Respondent had re-availed himself of protection in Iran, and that return to Iran would pose a real risk of torture or death, precluding refoulement. Consequently, some form of leave to remain would be granted regardless of the appeal's outcome.
Legal Issues Presented
- Whether the Secretary of State is required to carry out a balancing exercise weighing the degree of danger to national security against the cost, practicability, and feasibility of measures to mitigate the risk before revoking refugee status or refusing refugee status applications on national security grounds.
- Whether the decision of the Court of Justice of the European Union ("CJEU") in T v Land Baden-Wurttemberg forms part of retained EU law applicable in the United Kingdom post-Brexit.
- The proper interpretation of the concept of "danger to national security" within the Refugee Convention, the Qualification Directive, and domestic Immigration Rules.
Arguments of the Parties
Appellant's Arguments (Secretary of State)
- The Secretary of State argued there is no legal requirement to conduct the balancing exercise described by SIAC before revoking refugee status or refusing asylum on national security grounds.
- She contended the Qualification Directive is not retained EU law, and thus the CJEU decision in T is irrelevant.
- The decisions to revoke refugee status and refuse asylum are not decisions to refoule, so the balancing exercise mandated in T does not apply.
- Even if T applies, it does not require a balancing exercise or that revocation of refugee status be a measure of last resort.
Respondent's Arguments
- The Respondent supported SIAC's reasoning that revocation of refugee status requires a balancing exercise analogous to that required before refoulement.
- He submitted that non-refoulement is a fundamental right and only a sufficiently serious danger to national security can justify revocation or refoulement.
- Since the Qualification Directive provisions on revocation and refoulement are materially the same, the same balancing approach should apply to revocation of refugee status.

| T v Land Baden-Wurttemberg [2016] 1 WLR 109 (CJEU) | Interpretation of Articles 21(2) and 24(1) of the Qualification Directive concerning revocation of residence permits and refoulement. | The court found that revocation of residence permits may be justified on less demanding grounds than refoulement, and that refoulement should be a last resort. The court rejected the notion that refoulement is prohibited unless a proportionality/balancing exercise is conducted. |
| R (AAA) (Syria) v Secretary of State for the Home Department [2023] UKSC 42 | Weight to be accorded to UNHCR guidance and evidence; recognition of non-refoulement principle as part of customary international law. | The Supreme Court acknowledged UNHCR guidance as influential but not binding, emphasizing context in its application. |
| Zaoui v Attorney-General (No. 2) [2005] NZSC 38 | Definition and application of "danger to national security" exception under the Refugee Convention. | The New Zealand Supreme Court rejected a proportionality or balancing test in applying Article 33(2), supporting a sequential approach. |
| Othman v United Kingdom [2012] 55 EHRR 1 | Prohibition of refoulement where there is a real risk of torture or death contrary to Articles 2 and 3 ECHR. | Confirmed that even a person considered a national security risk cannot be refouled if it violates fundamental human rights. |

Court's Reasoning and Analysis
The court began by acknowledging the Secretary of State's conclusion that the Respondent poses a real and serious danger to national security, a conclusion entitled to significant deference due to the Secretary of State's constitutional role and democratic accountability. The court examined the Refugee Convention's Article 33, particularly paragraph (2), which allows refoulement of refugees regarded as a danger to national security without requiring a balancing exercise against the harm the refugee might face if returned.
The court analyzed the Qualification Directive and the Immigration Rules, noting their alignment with Article 33(2) and the absence of any language mandating a balancing exercise before revocation of refugee status. It emphasized that section 34(1)(b) of the Anti-terrorism, Crime and Security Act 2001 expressly prohibits balancing national security danger against the consequences to the refugee if returned.
The court critically assessed SIAC's reliance on UNHCR Guidance and the CJEU decision in T. It found that the UNHCR Guidance introduces an additional proportionality test that goes beyond the text of the Refugee Convention and is therefore not binding. The court held that existing international human rights obligations, including the prohibition of torture and the right to life, already provide adequate safeguards against disproportionate refoulement.
Regarding T, the court concluded that the case concerned revocation of residence permits under a less demanding standard than refoulement and did not impose a requirement for a balancing exercise before revocation of refugee status or refusal of asylum. The court found that SIAC read too much into the judgment in T, and that no such balancing exercise is legally required.
Finally, the court confirmed that the CJEU decision in T forms part of retained EU law by virtue of the Withdrawal Act 2018 and subsequent amendments, but that this did not affect the court's conclusion on the absence of a balancing obligation.
Holding and Implications
The court ALLOWED THE APPEAL, overturning SIAC's decision that the Secretary of State's revocation of the Respondent's refugee status and refusal of a further refugee status application were unlawful.
The court held that there is no legal requirement for the Secretary of State to carry out a balancing exercise weighing the degree of danger to national security against the cost, practicability, or feasibility of mitigating measures before revoking refugee status or refusing asylum on national security grounds. Once the Secretary of State concludes that a person is a danger to national security, she is entitled to revoke refugee status.
The decision clarifies the interpretation of Article 33(2) of the Refugee Convention, the Qualification Directive, and the Immigration Rules, emphasizing that the statutory and international framework does not impose a proportionality or balancing test beyond the existing safeguards from human rights obligations prohibiting refoulement where there is a real risk of torture or death.
No new precedent was established beyond affirming the Secretary of State's discretion and the non-requirement of a balancing exercise. The decision underscores the constitutional role of the Secretary of State in national security matters and confirms the status of CJEU decisions as retained EU law post-Brexit, without extending their scope beyond their original context.
