U3 v Secretary of State for the Home Department
[2023] EWCA Civ 811
SIAC's jurisdiction is appellate, not supervisory. It can only consider whether the Secretary of State acted in a way no reasonable decision-maker could have, considered irrelevant matters, disregarded relevant ones, or erred in law.
Begum v Secretary of State for the Home Department [2024] EWCA Civ 152
In national security cases, SIAC accords deference to the Secretary of State's assessment, but scrutinizes the evidence with a 'powerful microscope'.
Begum v Secretary of State for the Home Department [2024] EWCA Civ 152
Relevant considerations in exercising statutory powers include mandatory, prohibited, and permissible considerations. The Wednesbury unreasonableness test applies to permissible considerations – a consideration must be 'obviously material' to justify interference.
R v Somerset County Council, ex parte Fewings [1995] 1 WLR 1037
Procedural fairness is a question for the court to determine, not subject to Wednesbury review.
R (Osborn) v Parole Board [2013] UKSC 61
Anxious scrutiny applies when an administrative decision may put an applicant's life at risk, requiring careful consideration of all factors.
Bugdaycay v Secretary of State for the Home Department [1987] AC 514
Deprivation of citizenship is a 'radical step', requiring a correspondingly strict standard of review.
Pham v Secretary of State for the Home Department [2015] UKSC 19
The Court of Appeal dismissed the appeal.
The Court found that while SIAC erred in its approach to procedural fairness (applying Wednesbury instead of an independent assessment), the error was not material. The Court also found that the advice to the Secretary of State was fair and balanced, and that SIAC applied the necessary level of scrutiny.
