UK publishes statement explaining terrorist-organisation proscription decisions
Published October 26, 2026 · Official Home Office policy statement
What is new
The Home Office published a statement on October 26 explaining the policies and procedures used to ban terrorist organisations under section 3 of the Terrorism Act 2000. Publication fulfils a requirement of the Crime and Policing Act 2026.
How the process works
The statement describes a statutory test followed by ministerial discretion, informed by a cross-government review group. Ordinary proscription orders require approval by both Houses of Parliament; an urgent procedure is also available.
It also explains how affected organisations or individuals can seek removal from the list. Ministers must determine a deproscription application within 90 days from the day after receipt. A refusal can be appealed to the Proscribed Organisations Appeals Commission.
Why the distinction matters
This is a statement explaining decision-making, not an announcement of a new organisation’s ban. It separately describes the state-threat designation power under national-security legislation. Readers should distinguish those designations from terrorist-organisation proscription and from a criminal conviction.
