On June 15, 2026, a five-judge appeals court ruled that the UK government was allowed to ban Palestine Action as a terrorist organisation. This reversed an earlier decision by a lower court in February that had said the ban was wrong.

The reversal matters because it settles — at least for now — an unusual legal tangle. The government had banned the group under anti-terrorism laws, but then a high-ranking judge disagreed and said that ban went too far. Now, a more senior court has backed the government.

What the Lower Court Said

In February, a judge looked at what Palestine Action actually does and found that most of its illegal activities — damaging property, trespassing, throwing paint at military contractor buildings — are serious crimes. But the judge argued they aren't terrorism in the legal sense. Ordinary criminal law, he concluded, was enough to punish these acts. Banning the whole group under terrorism laws was overkill.

When you ban a group as "terrorist," membership and even speaking in support of it become crimes. People can go to prison just for being associated with it. The February judge thought that was too harsh for a group that mostly did direct action protests, not violence that aims to spread fear for political goals.

What the Appeals Court Said

The five judges at the Court of Appeal disagreed. They looked at Palestine Action's behaviour and decided it did fit the legal definition for a terrorist ban. They rejected the February judge's argument that the law required them to consider whether ordinary criminal charges would be enough. The appeals judges saw the group differently than the lower court had.

Al Jazeera reported that the judges found Palestine Action was not simply a peaceful protest group — directly contradicting how the organisation describes itself.

This legal disagreement has real consequences. Since the ban went into effect, hundreds of people have been arrested on charges related to Palestine Action, according to BBC reporting. All those prosecutions now rest on a ban that a higher court says is lawful.

What Happens Next

Palestine Action can ask the UK Supreme Court — the highest court in the land — to review the case. The Supreme Court doesn't have to accept every appeal, but this one involves a big legal question: how much discretion should the government have when deciding whether to ban a group as terrorist?

This matters beyond Palestine Action. Very few banned groups have the money or political support to fight their designation in court, so most proscription decisions never get tested by judges. If the Supreme Court takes up this case, its ruling would set a precedent that future governments would have to follow when banning organisations.

Liberty, a human rights group, published an analysis the same day the ruling came down. The group flagged a civil liberties concern: that terrorism laws have increasingly been used to criminalise people simply for their association with a cause, rather than for specific dangerous conduct. This is a legitimate worry, even though the Court of Appeal has now said the ban is legally sound.

The judges were answering a narrow question: did the government stay within its legal powers and follow the rules when it made the ban? They were not answering the bigger policy question: is banning a protest group — whose main activities involve property damage and disruption — the right choice in the first place? That broader argument remains open.

For anyone following UK protest laws and how courts balance national security against civil liberties, the gap between what the February judge said and what the five appeals judges said tells the real story. It shows disagreement about what counts as terrorism, and about how much weight judges should give to the government's decision-making. That argument isn't finished.
