A British pro-Palestinian group intends to appeal a possible ban.

The Action Group for Palestine announced on Monday that it has initiated legal proceedings to challenge a potential decision by the British government to ban it under anti-terrorism laws.

The ban, expected to be introduced in parliament on Monday, would make membership in the group a criminal offense. The announcement came days after activists from the group damaged two British military aircraft in protest against London's support for Israel, according to Reuters.

The group had earlier condemned the government's move, describing it as an "irrational reaction," and said that London's High Court had scheduled an urgent hearing for Friday to consider permission to challenge the ban.

The group is seeking a court order to prevent the government from banning it while its case is being heard.

The request includes written statements from Amnesty International human rights experts and others who expressed concern about "the unlawful misuse of counter-terrorism measures to criminalize dissent."

“The court’s decision to schedule an urgent hearing this week demonstrates the vital importance of what is at stake in this case, including the far-reaching implications that banning the Palestine Action Group could have on freedom of opinion, expression, and assembly in Britain,” said Huda Ammuri, co-founder of the group.

Under British law, the Home Office can ban a group if it is believed to be committing, encouraging, or "involved in terrorism." Banning would place the group in a similar classification to the Palestinian Islamic Resistance Movement (Hamas), Al-Qaeda, or ISIS.

The Ministry of Interior declined to comment on the group's planned legal appeal.

Home Secretary Yvette Cooper had previously said the group had a "long history of unacceptable criminal damage" and that the government would not tolerate those who endangered national security.

Since the start of the Gaza conflict in 2023, the Action Group for Palestine has regularly targeted British sites linked to the Israeli defense industry company Elbit Systems, as well as other companies in Britain with ties to Israel.
