Adam Tomkins: On ABJ: Proscribed Organisations, Proportionality, and Freedom of Speech – UK Constitutional Law Association
‘In R v ABJ [2026] UKSC 8 a unanimous Supreme Court ruled that the offence of expressing support for a proscribed organisation, as defined in the Terrorism Act 2000, is not a disproportionate interference with the right to freedom of expression under the European Convention on Human Rights. The Court’s verdict was no surprise: the Court of Appeal had reached the same conclusion ([2024] EWCA Crim 1597) and the case sits alongside earlier appeal court rulings upholding the compatibility with Convention rights of other Terrorism Act offences relating to proscribed organisations: notably, R v Choudary [2016] EWCA Crim 61 (on inviting support for a proscribed organisation) and Pwr v DPP [2022] UKSC 2 (on carrying or displaying an article supportive of a proscribed organisation).’
