UK High Court Rules Ban on Palestine Action Unlawful: A Landmark Test of State Power and Civil Liberties
On 13 February 2026, the delivered a landmark judgment: the UK government’s decision to designate as a terrorist organisation was unlawful and disproportionate.
The ruling strikes at the heart of one of the most powerful tools available to the British state — proscription under the Terrorism Act 2000.
It is a rare judicial rebuke of executive authority in national security matters.
What Was the Ban?
In July 2025, the Home Office formally proscribed Palestine Action, making:
- Membership a criminal offence
- Public support punishable by up to 14 years in prison
- Displaying symbols potentially illegal
The decision was initially taken by Home Secretary , Yvette Cooper who argued the group’s activities — including break-ins at RAF bases, property damage, and direct action targeting — met the statutory definition of terrorism.
Proscription is among the most severe restrictions the UK government can impose on a political organisation. It effectively places a group in the same legal category as internationally recognised terrorist networks.
What Did the Court Decide?
The High Court ruled that:
- A small number of the group’s actions technically fell within the statutory definition of terrorism.
- However, the nature, scale, and persistence of those actions did not justify banning the entire organisation.
- The Home Secretary failed to properly apply the proportionality test required under law.
- Existing criminal laws were sufficient to address unlawful acts.
Most importantly, the court held that proscription constituted a serious interference with:
- Freedom of expression
- Freedom of assembly
Both protected under the European Convention on Human Rights.
The judgment emphasized that proscription is a “draconian” power and must be used only where strictly necessary.
Why This Ruling Matters
This decision is significant for several reasons:
1️⃣ A Rare Overturning of Terror Designation
It is believed to be the first successful High Court challenge to a UK terrorist proscription.
2️⃣ Clarifying the Meaning of “Terrorism”
The ruling draws an important legal distinction between:
- Criminal damage
- Disruptive protest
- Acts intended to terrorise the public
The court effectively said: not all militant protest equals terrorism.
3️⃣ A Constitutional Warning
The judgment sends a clear message that national security powers are not beyond judicial scrutiny.
Even in politically charged contexts, courts will test whether the government has met the high threshold required to curtail fundamental rights.
What Happens Next?
Although the court ruled the decision unlawful, the proscription remains temporarily in force pending appeal.
The current Home Secretary, , has indicated the government intends to challenge the ruling.
A further hearing is scheduled to determine whether the ban should be suspended while the appeal proceeds.
Meanwhile, hundreds of ongoing prosecutions related to alleged support for Palestine Action may now face legal uncertainty.
The Broader Political Context
The case unfolds against a backdrop of heightened political tensions around Gaza, protest movements, and accusations that governments are increasingly stretching counterterrorism laws to regulate dissent.
Critics argue that expanding terrorism designations to cover activist networks risks diluting the meaning of terrorism itself.
Supporters of the ban contend that repeated sabotage of military infrastructure justifies strong measures.
The High Court did not exonerate unlawful conduct. Instead, it ruled that existing criminal law — not terrorism legislation — was the appropriate response.
A Defining Question
At stake is a fundamental question:
When does disruptive political activism cross the threshold into terrorism?
The High Court’s answer is clear:
The threshold is high — and the state must prove necessity, not merely seriousness.
In a democratic society, the power to label an organisation “terrorist” must remain exceptional.
This case will likely become a defining precedent in debates over civil liberties, protest rights, and the expanding reach of counterterrorism law in the United Kingdom.
