- Covers the legal reasoning and factual background of Secretary of State for the Home Department v R (Huda Ammori), where the Court of Appeal held in favour of the home secretary and set aside the quashing order made by the Divisional Court on 25 February 2026.
On 23 June 2025, the home secretary announced she had decided to proscribe Palestine Action as a terrorist organisation under s 3 of the Terrorism Act 2000 (TA 2000). Following approval by both Houses of Parliament, a proscription order came into effect on 5 July 2025. Although the Divisional Court quashed the proscription decision on 13 February 2026 (holding it both inconsistent with the home secretary’s proscription policy and disproportionate), the Court of Appeal on 15 June 2026 upheld the Home Secretary’s decision. This was The Secretary of State for the Home Department v R (Huda Ammori) [2026]
