Key Takeaways
- The UK Home Office is appealing a High Court ruling that declared the proscription of Palestine Action as a terrorist organization unlawful.
- The February judgement called the ban “disproportionate” and emphasized that the group’s activities are peaceful protest, not terrorism.
- Despite the ruling, the proscription remains in force during the appeal process, and showing support for Palestine Action can still lead to arrest under terror laws.
- Over 2,700 individuals have been arrested since the ban, including high‑profile figures such as Greta Thunberg, Sally Rooney and Ilan Pappé, who publicly declared support for the group.
- Human‑rights organizations (Amnesty International, Human Rights Watch) condemn the ban as an overreach that undermines freedom of expression and equates peaceful activism with armed groups like ISIL and al‑Qaeda.
- The Court of Appeal hearing began on Tuesday, 28 April 2026, with no indication yet of when a judgment will be issued.
Background of the Legal Dispute
The conflict stems from the UK government’s decision in summer 2025 to list Palestine Action—a direct‑action network founded in 2020 by Huda Ammori and former Extinction Rebellion activist Richard Barnard—as a terrorist organisation under the Terrorism Act 2000. The group’s stated aim is to pressure companies linked to the Israeli military through non‑violent civil disobedience, such as displaying signs reading “I oppose genocide. I support Palestine Action.” Authorities argued that the group’s tactics facilitated or encouraged violence, thereby justifying the proscription.
High Court Ruling
In February 2026, a panel of senior judges at the High Court overturned the Home Office’s designation, ruling that the ban was “disproportionate” and unlawful. The judgement underscored that Palestine Action’s activities consist primarily of peaceful protest and that labelling the group as a terrorist entity blurred the line between legitimate activism and criminal conduct. The judges highlighted the lack of evidence linking the organisation to planning or executing violent attacks, concluding that the state’s measure exceeded what was necessary for national security.
Government’s Appeal and Court of Appeal Hearing
Unsatisfied with the High Court’s decision, the Home Secretary, Shabana Mahmood, lodged an appeal, prompting a two‑day hearing before the Court of Appeal that commenced on Tuesday, 28 April 2026. The government argues that the lower court misinterpreted the threat posed by Palestine Action and that the proscription is a proportionate response to prevent potential facilitation of violence. The appellate judges will examine whether the original ban satisfied the legal tests of necessity and proportionality under counter‑terror legislation.
Impact on Protesters and Arrests
Since the ban took effect, more than 2,700 individuals have been arrested under terrorism offences for expressing support for Palestine Action, often simply by holding protest signs. Initially, London’s Metropolitan Police indicated that arrests would cease following the High Court ruling, but the force reversed that stance weeks later. Recent demonstrations have seen large numbers detained, including over 200 protesters in central London earlier this month, illustrating that the legal uncertainty continues to affect activists on the ground.
Responses from Celebrities and Scholars
The case has attracted significant public attention, prompting a letter signed by notable figures such as novelist Sally Rooney, climate activist Greta Thunberg, and Israeli historian Ilan Pappé. The signatories declared, “We oppose genocide, we support Palestine Action,” thereby risking arrest under the extant terrorism legislation. Their intervention has amplified the debate over whether the state’s counter‑terror powers are being used to stifle legitimate dissent concerning Israel’s actions in Gaza.
Human Rights Concerns and Allegations
Remand prisoners and activists on bail have claimed that their human rights have been violated due to their alleged association with Palestine Action, citing prolonged detention, restrictive bail conditions, and, in some instances, hunger strikes demanding the ban’s removal. The Ministry of Justice has denied these allegations, asserting that all detainees are treated according to standard legal procedures. Nonetheless, rights monitors continue to scrutinize the treatment of those linked to the group.
Statements from Rights Organizations
Amnesty International’s 2025/2026 annual report criticized the UK for “continu[ing] to use counterterror laws to restrict peaceful protests against the genocide in Gaza and ban the organisation Palestine Action,” noting that arms exports to Israel persisted concurrently. Human Rights Watch warned that “when the state blurs the line between activism and terrorism, it is not defending security, it is undermining freedom.” Both organisations urged the government to withdraw the appeal and reconsider the proportionality of its counter‑terror measures.
Uncertainty and Future Outlook
As of the time of publishing, the Court of Appeal has not indicated a timeline for delivering its judgment. The outcome will determine whether the Home Office’s appeal succeeds, potentially reinstating the full terror‑proscribed status of Palestine Action, or whether the High Court’s finding of disproportionality stands, paving the way for a possible repeal of the ban. Until then, the legal status of the group remains in limbo, leaving thousands of supporters vulnerable to arrest and prompting ongoing debate over the balance between national security and the right to peaceful protest in the United Kingdom.
