Britain's Supreme Court will consider an appeal challenging a court decision that upheld the government's designation of Palestine Action as a terrorist organization, according to Reuters.

In June, London's Court of Appeal reversed an earlier High Court finding that the ban violated freedom of expression. Lady Chief Justice Sue Carr determined that the organization's conduct did not reflect nonviolent protest and that the proscription was justified and proportionate. She stated the ban was "highly controversial" But emphasized it would be "a fundamental mistake to overlook the fact that Palestine Action overtly promoted unlawful violence amounting to terrorism."

Huda Ammori, a co-founder of the group, has been granted permission to appeal the ruling, Reuters reported. Ammori stated: "We will continue to fight this proscription all the way to the Supreme Court and, if necessary, to the European Court of Human Rights ⁠to overturn what has become one of the most extreme attacks on free speech and the right to protest in modern British history."

The British government outlawed Palestine Action in July 2025 following incidents involving members vandalizing aircraft at a Royal Air Force base and occupying premises linked to Israel.

A British judge previously sentenced four Palestine Action activists to combined prison terms exceeding 20 years for a 2024 attack on an Elbit Systems UK factory, which resulted in approximately £1 million in damage and left a police officer with a fractured spine. The judge noted the case had "terrorist connections."
