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

The appeal is brought by Huda Ammori, co-founder of Palestine Action, following a Court of Appeal judgment that overturned the Divisional Court’s finding that the proscription was unlawful.

Represented by Garden Court counsel Henry Blaxland KC, Owen Greenhall and Audrey Cheryl Mogan, Huda Ammori’s case is that the decision to proscribe Palestine Action is in breach of the rights to freedom of expression and association under Articles 10 and 11 of the European Convention on Human Rights (ECHR).

Garden Court Chambers counsel Henry Blaxland KC, Owen Greenhall, and Audrey Cherryl Mogan represent Huda Ammori alongside co-counsel Raza Husain KC, Mira Hammad, Grant Kynaston, Paul Luckhurst, Tim James-Matthews, and Zoe Brereton.
