A ruling by the British Court of Appeal upholding the Home Office’s decision to designate the activist group Palestine Action as a terrorist organisation has sparked widespread criticism among legal and human rights circles. Critics have warned that the decision could have far reaching consequences for civil liberties and the right to protest in the United Kingdom.
The ruling comes after a series of legal actions targeting members of the group, prompting questions about the future of pro Palestine activism in Britain amid mounting political and media pressure linked to Israel’s war on the Gaza Strip.
Human Rights Lawyer Calls the Ruling “A Miscarriage of Justice”
British broadcaster LBC quoted prominent human rights lawyer Michael Mansfield as sharply criticising the sentences handed down against members of Palestine Action.
Mansfield described the conviction of four activists as terrorists as “a terrifying development”, arguing that the case amounted to “a miscarriage of justice”.
He is one of Britain’s most prominent human rights barristers and is widely known for representing major public interest cases, including the murder of Stephen Lawrence and the Grenfell Tower fire.
Mansfield was also among dozens of lawyers who signed a legal letter stating that prosecuting activists as terrorists would violate fundamental legal principles.
Former Judge Warns of a “Serious Flaw”
In separate remarks to LBC, former UK Supreme Court judge Lord Jonathan Sumption said there was a “serious flaw” in the application of counter terrorism legislation in relation to Palestine Action.
He argued that the use of terrorism laws against the group raised important legal questions regarding the government’s interpretation of the law and whether such an approach was compatible with citizens’ fundamental rights.
What Is Palestine Action?
Palestine Action was founded in Britain in 2020 as a network of activists employing direct action tactics to pressure companies and institutions it says are involved in supplying weapons to Israel or supporting military industries connected to the Israeli occupation.
The movement began by targeting the London headquarters of Israeli arms manufacturer Elbit Systems before expanding its activities to dozens of sites and facilities linked to the defence sector across Britain.
Its methods include sit ins, blocking factory entrances, occupying buildings, spraying symbolic red paint, and damaging equipment that activists consider part of the arms industry.
The group says its objective is to disrupt companies cooperating with the Israeli military, while the British government and targeted firms describe its activities as unlawful acts of vandalism.
Who Leads the Movement?
The movement was co founded by British activist Richard Barnard and British Palestinian activist Huda Ammori, who has become one of the most recognisable figures in Britain’s pro Palestine movement.
Palestine Action says its central aim is to end what it describes as British support for the Israeli occupation and to support Palestinians’ right to self determination and the return of refugees.
The movement’s activities have grown significantly in recent years, leading the British government in July 2025 to ban the organisation under terrorism legislation, a move that triggered deep divisions between supporters and opponents.
Although Palestine Action succeeded in February this year in obtaining a High Court ruling declaring the ban unlawful, the Court of Appeal overturned that judgment on Monday, 15 June 2026.
In its ruling, the Court of Appeal held that the Home Office had acted within its legal powers when it banned the organisation.
The court stated that the decision had struck “a fair balance” between protecting public safety and safeguarding legal rights. It also concluded that the High Court had erred in interpreting the government’s prohibition policy and in its assessment of the principle of proportionality on which the ban was based.
The ruling comes amid a broader confrontation between British authorities and pro Palestine movements, with activists accusing the government of increasing efforts to restrict protests critical of the Israeli occupation.
Claims of a Wider Crackdown on Palestine Supporters
Activists argue that the targeting of Palestine Action extends beyond the organisation itself and reflects a broader trend aimed at restricting pro Palestine activism across Britain.
They point to previous attempts to limit demonstrations supporting Palestinians, including measures introduced by former Home Secretary Suella Braverman during the government of Rishi Sunak before her dismissal amid political controversy surrounding the war in Gaza.
Activists have also accused pro Israel lobbying groups of seeking to broaden the definition of antisemitism to include criticism of Israeli policies or calls to end British support for Tel Aviv.
Huda Ammori: We Will Not Surrender
For her part, Palestine Action co founder Huda Ammori said the movement would continue its legal battle despite the Court of Appeal ruling.
Speaking to the British newspaper The Guardian, Ammori said she remained confident that the legal challenge against the ban would ultimately succeed, whether through British courts or by appealing to the European Court of Human Rights.
She expressed disappointment with the ruling but insisted that the ban remained “disproportionate” and incompatible with the principles of freedom of expression and the right to protest.
Ammori added that legal and political efforts would continue until the decision was overturned or amended.
The case of Palestine Action has become one of the most contentious legal and political issues in Britain in recent years. Critics argue that it marks the first time terrorism legislation has been used to outlaw a direct action protest movement, while the government maintains that the organisation’s activities have gone beyond peaceful protest and now pose a threat to public security and public order.
