UK Government Appeals High Court Ruling on Palestine Action Proscription
4/29/2026, 2:37:30 AM
Legal Challenge and Appeal Overview
The Court of Appeal began hearing the Home Secretary Shabana Mahmood’s appeal on 28 April 2026 against a February High Court judgment that declared the proscription of the activist network Palestine Action unlawful. The appeal seeks to keep the ban in place while the court reviews the decision.
Background and Policy Context
Palestine Action was designated a terrorist organization under the Terrorism Act in July 2025, shortly after a June 2025 break-in at RAF Brize Norton in which activists sprayed red paint into the turbines of two military aircraft. The ban placed the group alongside organisations such as Islamic State and Boko Haram, making membership punishable by up to 14 years’ imprisonment. The move was the first use of the Terrorism Act to proscribe a direct-action protest group.
Key Figures and Organizations
- Shabana Mahmood – Home Secretary defending the proscription.
- Huda Ammori – Co-founder of Palestine Action and lead plaintiff in the judicial review.
- Yvette Cooper – Former Home Secretary who announced the ban, citing a “long history of unacceptable criminal damage.”
- Defend Our Juries (DOJ) – Grassroots coalition that organised mass civil-disobedience actions.
- Metropolitan Police Service – Enforced the ban, pausing arrests after the High Court ruling and later resuming them.
Timeline of Proscription and Litigation
- June 2025 – RAF Brize Norton break-in.
- 5 July 2025 – Formal proscription of Palestine Action under the Terrorism Act.
- February 2026 – High Court rules the ban unlawful on grounds of free-speech interference and policy breach.
- 28 April 2026 – Court of Appeal hearing commences.
Data and Arrest Statistics
- Over 2,700 individuals have been arrested for alleged support of Palestine Action under Section 13 of the Terrorism Act (maximum six-month sentence).
- Following the High Court decision, the Metropolitan Police paused arrests, then resumed, detaining more than 500 protesters in early 2026.
- Membership in the proscribed group carries a potential 14-year prison term.
Official Statements & Government Position
The Home Secretary’s legal team argues that the High Court’s assessment of the ban’s impact on freedom of expression is “overstated and wrong,” maintaining that the proscription remains necessary for national security. The Metropolitan Police has indicated that enforcement will continue pending the appeal’s outcome.
Criticism & Opposition
UN experts, civil-liberty organisations, lawyers and MPs across the political spectrum have warned that the ban sets a dangerous precedent by conflating protest with terrorism. A court-ordered compensation case for protester Laura Murton, who faced arrest for displaying a “free Gaza” sign, underscores concerns about police overreach. Unaffiliated pro-Palestine groups have also reported frozen bank accounts.
On-the-Ground Reports
Activists coordinated by Defend Our Juries staged demonstrations featuring placards reading “I oppose genocide, I support Palestine Action.” Police interventions have resulted in mass arrests, while some defendants remain on trial for criminal damage linked to a 2024 raid on Israeli defence firm Elbit Systems.
Conflicting Reports & Gaps
Sources differ on the maximum penalty for supporting the group: one cites a six-month term under Section 13, while another notes a 14-year term for membership. The precise legal distinction between “support” and “membership” remains unclear in public reporting.

What’s Next
The Court of Appeal’s decision will determine whether the proscription remains in force and could reshape the legal framework governing protest-related terrorism designations in the United Kingdom.
