High Court Rules Palestine Action Ban Unlawful, Government Appeals

February 20th, 2026: Consequential Hearing Scheduled

Overview

On February 13, 2026, Britain's High Court ruled the government acted illegally when it banned Palestine Action as a terrorist organization—the first to overturn a UK terrorism proscription. The three-judge panel said the group's tactics of breaking into factories and damaging military aircraft were criminal but did not meet the terrorism threshold, calling into question more than 2,700 arrests and 250 charges under the Terrorism Act.

The case tests where criminal protest ends and terrorism begins: Palestine Action spent four years targeting Israeli defense contractor Elbit Systems, forcing three UK factories to close through repeated break-ins and property damage. When activists breached RAF Brize Norton in June 2025 and spray-painted military aircraft engines, the government responded by placing the group alongside al-Qaeda and ISIS on Britain's terrorism list. The High Court said that went too far—but the ban stays in place while the government appeals, leaving thousands in legal limbo.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2001-2008

PMOI Deproscription Case (2008)

The People's Mojahedin Organization of Iran (PMOI), an Iranian opposition group, challenged its UK terrorism proscription through the Proscribed Organisations Appeal Commission. The group had been on Britain's terrorism list since 2001. The Commission found the government's decision to maintain the ban was 'perverse and flawed.'

Then

The Court of Appeal rejected the Home Office's appeal in May 2008, and PMOI was removed from the terrorism list in June 2008.

Now

The case established that proscription decisions could be successfully challenged and that the government must demonstrate ongoing terrorist activity. It also influenced EU courts to remove PMOI from their terrorism list.

Why this matters now

The only prior successful challenge to a UK terrorism proscription, demonstrating that courts can overrule Home Secretary discretion when evidence doesn't support the designation. Palestine Action's case follows the same appellate path.

2022-2025

Public Order Act 2023 and Protest Crackdown

Following disruptive protests by Extinction Rebellion, Just Stop Oil, and Insulate Britain, the UK passed the Public Order Act 2023. The law created new offenses including 'locking on' and expanded police powers to restrict protests causing 'serious disruption.' In July 2024, five Just Stop Oil activists received two to five year prison sentences for organizing a protest via Zoom.

Then

Arrests and prosecutions of climate activists increased sharply. The High Court ruled the Just Stop Oil sentences 'manifestly excessive' in March 2025.

Now

The UN High Commissioner and Council of Europe criticized UK laws as violating international human rights standards. Human Rights Watch documented what it called systematic attacks on protest rights.

Why this matters now

The Palestine Action proscription represents an escalation beyond the 2023 law—using terrorism designation rather than expanded protest offenses. The pattern shows progressive expansion of state powers against direct action groups.

2019

Extinction Rebellion Counter-Terrorism Listing (2019)

The South East Counter Terrorism Unit included Extinction Rebellion in a guide listing extremist ideologies alongside neo-Nazi and Islamist groups. After media exposure, police recalled the document and called XR's inclusion an 'error.' Policy Exchange, a think tank with oil industry funding, had published a report calling XR an 'extremist' organization months earlier.

Then

The listing was withdrawn after public outcry and criticism from politicians across parties.

Now

The incident highlighted tensions between police counter-terrorism operations and civil liberties, and foreshadowed debates that would intensify with Palestine Action's formal proscription.

Why this matters now

Shows the government previously backed down when attempting to categorize non-violent direct action groups as extremist threats. Palestine Action's formal proscription crossed a line that authorities had retreated from before.
