Police Service of Northern Ireland (PSNI) referred 32 files to the Public Prosecution Service (PPS) over alleged displays of support for proscribed organisations linked to Palestine Action. This accounts for one-third of 90 total files since the Terrorism Act took effect in July 2000. The remaining cases include 48 related to republican paramilitary groups and 10 to loyalist paramilitary organisations.

Each file may cover multiple individuals, such as those charged after a parade. The PSNI obtained these figures through a freedom of information request. Referrals for Palestine Action rose from six in November 2025 to 18 by year-end, then nearly doubled in early 2026.

The alleged offences violate Section 13 of the Terrorism Act 2000, which prohibits wearing, carrying or displaying items in public that arouse reasonable suspicion of membership or support for a proscribed organisation. The UK government banned Palestine Action in July 2025.

PSNI issued advisory letters to individuals at risk of breaching the law, including more than a dozen sent by November 2025 to people holding weekly vigils in Derry. A PSNI spokesperson stated that rights to freedom of speech and peaceful assembly are protected by law, and police submit evidence files to the PPS when offences are suspected.

Patrick Corrigan, Northern Ireland director for Amnesty International, contacted the Chief Constable and Director of Public Prosecutions in August 2025 regarding use of counter-terrorism powers in protests. Daniel Holder from the Committee on the Administration of Justice noted the high proportion of files for a recently proscribed group.
