The Supreme Court will today (4 November 2026) begin hearing an appeal into the lawfulness of the Home Secretary’s decision to proscribe Palestine Action as a terrorist organisation in July 2025.

In written submissions, counsel representing Palestine Action founder Huda Ammori argue that the proscription pursuant to Section 3 of the Terrorism Act 2000 is not compatible with Articles 10 and 11 of the European Convention on Human Rights.

The appeal marks the first time that the Supreme Court will consider the exercise of the Home Secretary’s power to proscribe in the context of convention rights.

Following a legal challenge brought by Palestine Action founder Ms Ammori, the High Court ruled in February 2026 that the proscription was an “unlawful” interference with Articles 10 and 11 of the ECHR.

The Home Secretary appealed to the Court of Appeal, which overturned the High Court’s decision in June 2026. The Supreme Court then granted Ms Ammori permission to appeal against the Court of Appeal’s decision in August.

The case is hugely significant in addressing widespread concerns about the right to free speech and protest which the proscription suppresses, according to the United Nations’ Special Rapporteur on Counter-Terrorism, an intervener on the case. In his words, the proscription was “out of step with comparable liberal democracies, including in Europe and various common law States.”

Garden Court North’s Mira Hammad was instructed by Birnberg Peirce Solicitors and Kellys Solicitors to represent Ms Ammori. She is led by Raza Husain KC of Matrix Chambers and Henry Blaxland KC of Garden Court Chambers. Other junior counsel for Ms Ammori are Owen Greenhall and Audrey Mogan of Garden Court Chambers, Zoë Brereton and Tim-James Matthews of Matrix Chambers, and Paul Lukhurst and Grant Kynaston of Blackstone Chambers.
