Factual and Procedural Background
The linked cases concern whether the High Court's supervisory jurisdiction, exercisable by judicial review, extends to decisions of the Special Immigration Appeals Commission (SIAC) and the Upper Tribunal (UT) that are not subject to appeal. The impugned decisions include SIAC's revocation of bail granted to Claimant U and refusal of bail to Claimant XC, and UT's refusal of permission to appeal against a First-tier Tribunal (FTT) decision concerning child maintenance payable by Claimant Cart.
Claimants seek to challenge these decisions by judicial review. The defendants, comprising the Secretary of State for the Home Department, the Secretary of State for Justice, and the Child Maintenance and Enforcement Commission, contend that SIAC and UT, as superior courts of record, are immune from judicial review or that such jurisdiction applies only in rare exceptional cases. The jurisdiction issue was directed to be heard as a preliminary matter in all three claims.
Separately, in the cases of U and XC, there is a question whether SIAC's decisions to revoke or refuse bail violated Article 5(4) of the European Convention on Human Rights (ECHR) due to reliance solely on closed material not disclosed to the claimants. This "Article 5(4) issue" arises only if the claimants succeed on the jurisdiction issue.
Claimant U is an Algerian national detained under national security grounds since 2001, with a complex history including deportation proceedings and bail granted and subsequently revoked by SIAC based entirely on closed evidence. Claimant XC is a Pakistani national detained under suspicion of terrorist-related activity, whose bail application was refused by SIAC also relying on undisclosed closed material. Claimant Cart is involved in child maintenance proceedings where UT refused permission to appeal on a particular ground, leading to the judicial review claim.
Legal Issues Presented
- Whether the High Court’s supervisory jurisdiction by way of judicial review extends to decisions of SIAC and UT that are not subject to appeal.
- Whether SIAC’s decisions to revoke or refuse bail violated Article 5(4) ECHR due to reliance on closed material without disclosure to the claimants.
- Whether, as superior courts of record, SIAC and UT are immune from judicial review or only subject to it in rare and exceptional cases.
- Whether UT, by virtue of its statutory powers and position in the tribunal structure, constitutes an alter ego of the High Court, affecting its amenability to judicial review.
Arguments of the Parties
Defendants' Arguments
- SIAC and UT are designated by statute as superior courts of record and are therefore immune from judicial review.
- Even if not immune, judicial review jurisdiction applies only in rare and exceptional circumstances, which do not include the present cases.
- Reliance on the statutory deeming provisions (SIACA s.1(3) and TCEA s.3(5)) excludes the High Court’s supervisory jurisdiction over SIAC and UT decisions.
- On the Article 5(4) issue, the Secretary of State argued that closed material should be handled by special advocates and that bail applications, being ancillary and temporary, require a less stringent procedural standard than that established in Strasbourg case law.
Claimants' Arguments
- The statutory designation of SIAC and UT as superior courts of record does not exclude judicial review jurisdiction, which can only be ousted by clear and explicit words.
- Judicial review is a key mechanism to uphold the rule of law and ensure statutory powers are properly exercised.
- SIAC is amenable to judicial review for excess of jurisdiction, including errors of law, as it possesses only limited jurisdiction conferred by statute.
- UT, although a superior court of record, is an alter ego of the High Court and not subject to judicial review for errors of law within its jurisdiction, but judicial review may be available for jurisdictional excess or procedural unfairness in exceptional cases.
- On the Article 5(4) issue, the claimants submitted that reliance solely on closed material without sufficient disclosure to enable effective instructions to special advocates violates the procedural fairness guaranteed by Article 5(4) ECHR, relying on the Strasbourg case A and others v United Kingdom and the House of Lords decision in Home Secretary v AF & Ors (No 3).

Court's Reasoning and Analysis
The court began by addressing the defendants’ contention that statutory designation of SIAC and UT as superior courts of record excludes judicial review jurisdiction. It held that such exclusion can only occur by clear and explicit statutory language, which is absent here. The deeming provisions in SIACA s.1(3) and TCEA s.3(5) do not explicitly exclude judicial review, and the court rejected the argument that mere designation as a superior court of record ipso facto confers immunity from judicial review.
The court then examined the historical and doctrinal meaning of "superior court of record" and distinguished three key distinctions: (1) courts presumed to act within jurisdiction versus those that must show jurisdiction on the face of proceedings; (2) courts amenable to judicial review versus those immune; and (3) courts of limited versus unlimited jurisdiction. The court concluded that the term "superior court of record" is not a reliable indicator of immunity from judicial review.
Applying these principles, the court found that SIAC, possessing a limited statutory jurisdiction, remains amenable to judicial review for excess of jurisdiction, including errors of law, and is not an alter ego of the High Court. The fact that SIAC is chaired by High Court judges does not confer immunity.
In contrast, the UT, as apex of a unified tribunal structure with wide jurisdiction and statutory power to grant judicial review applying High Court principles, was held to be an alter ego of the High Court. Consequently, UT is not amenable to judicial review for errors of law committed within its jurisdiction. Judicial review of UT decisions is only conceivable in very limited, exceptional circumstances, such as jurisdictional excess or substantial denial of a fair hearing. The court emphasized proportionality and the comprehensive appellate and review mechanisms available within the tribunal system, cautioning against unnecessary duplication of judicial review.
Regarding the Article 5(4) issue, the court considered Strasbourg jurisprudence, particularly A and others v United Kingdom, which requires that detainees be provided with sufficient disclosure to enable effective instructions to special advocates when closed material is relied upon. The court rejected the Secretary of State’s submission that bail applications, being ancillary and temporary, merit a less stringent procedural standard. The House of Lords decision in Home Secretary v AF & Ors (No 3) reinforced that the minimum disclosure standard applies even in non-detention control order cases. The court held that SIAC’s decisions to revoke or refuse bail based solely on undisclosed closed material without adequate gist violated Article 5(4).
Holding and Implications
The court’s final decision is as follows:
Claimants U and XC succeed on the jurisdiction issue and the Article 5(4) challenge. SIAC’s decisions to revoke or refuse bail based solely on undisclosed closed material violated their rights under Article 5(4) ECHR.
Claimant Cart’s application is dismissed. The court held that UT, as an alter ego of the High Court, is not amenable to judicial review for errors of law within its jurisdiction, and judicial review will only lie in rare and exceptional circumstances not present here.
The decision clarifies that statutory designation of a body as a superior court of record does not, without clear language, exclude judicial review. It affirms the constitutional principle that judicial review is a key mechanism to uphold the rule of law by ensuring that statutory powers are properly exercised. The ruling emphasizes the importance of procedural fairness in bail decisions involving closed material, aligning domestic law with Strasbourg jurisprudence.
No new precedent is established beyond these determinations, but the judgment provides authoritative guidance on the scope of judicial review over specialist tribunals and the application of Article 5(4) ECHR in bail contexts.
