A UK Court of Appeal upheld the government's decision to designate Palestine Action as a terrorist organization on Monday, June 15 [1].

The ruling maintains a strict legal ban on the group, which allows the state to prosecute members for association and prevents the organization from operating legally within the United Kingdom.

Five judges ruled that the ban was lawful [1]. The decision reverses a previous High Court judgment from February 2026 [1]. The Home Secretary originally designated the group as a terrorist organization due to alleged involvement in extremist activity [1], [2].

Huda Ammori, co-founder of Palestine Action, said the ban is unlawful and the group will keep fighting it wherever they can [3]. She said that the organization intends to take the matter to the Supreme Court if necessary [2].

"We will win this fight in the courts or on the streets," Ammori said [1].

The legal victory for the government removes a significant hurdle for prosecutors. More than 700 criminal cases may now proceed following the court's decision [4].

Palestine Action argues that the designation exceeds the Home Secretary's discretion and violates fundamental civil liberties [1], [2]. The group has focused its activities on protesting arms sales, and targeting companies involved in the defense industry.

"We will win this fight in the courts or on the streets."

This ruling significantly strengthens the UK government's ability to dismantle Palestine Action by validating the use of counter-terrorism legislation against the group. By clearing the way for over 700 criminal cases, the decision shifts the conflict from a debate over civil liberties to a massive wave of individual prosecutions, potentially neutralizing the group's operational capacity while they pursue a final appeal.
