UK Government Appeals Court Ruling on Proscription of Palestine Action
4/29/2026, 3:16:40 AM
Legal Battle Over the Proscription
On 28 April 2026 Court of Appeal in London began hearing Home Office’s challenge to a February 2026 High Court judgment that declared the proscription of Palestine Action unlawful. The appeal seeks to overturn the finding that ban imposed under the Terrorism Act 2000 was “disproportionate” while it remains in force.
Background and Timeline
Palestine Action was proscribed in July 2025 after activists broke into RAF Brize Norton base in June 2025, damaging two aircraft. Designation placed the group alongside organisations such as Islamic State, making membership punishable by up to 14 years. High Court in February 2026 ruled ban unlawful and left it in place pending appeal.
Key Actors and Numbers
Lawyers for Interior Minister Shabana Mahmood present appeal. Co-founder Huda Ammori, who launched challenge, says the ban curtails free speech and assembly. Home Office argues the group remains a serious security threat. Over 2,700 people have been arrested for displaying signs, with more than 500 arrests after High Court ruling. About 1,700 academics, writers and cultural figures signed a letter supporting group.
Government Position
Home Office argues the proscription was justified on security grounds and necessary to counter a serious threat. Lawyers for Minister Mahmood contend the High Court’s assessment of the ban’s impact on freedom of expression was overstated and wrong. Metropolitan Police says enforcement actions comply with existing law.
Opposition and Criticism
Huda Ammori says the proscription imposes severe restrictions on fundamental free speech and assembly rights of vast numbers of people and calls it a restriction on protest rights that violates the law. A letter read in court, signed by 1,700 academics, writers and cultural figures, expressed opposition to genocide and support for Palestine Action.
Conflicting Findings and Gaps
High Court concluded the ban was “disproportionate” and unlawful in its effect on expression, while government argues the designation is proportionate to a serious security threat. Ban stays in force during appeal, creating legal limbo where arrests continue but charges could be dismissed if the appeal overturns the finding.

Implications and Next Steps
The appeal will decide whether proscription remains legally defensible, shaping the balance between national security policy and protected civil liberties in the United Kingdom. Court of Appeal is expected to deliver its judgment after submissions on 29 April. A final ruling could affect arrests, pending charges, and legal framework governing protest linked to designated terrorist organisations.
