National Security Law, Procedure and Practice

This book considers national security law with reference to the use, protection, and disclosure of intelligence and other secret material. It analyses the substantive law relating to national security, its practice, and related procedures, and the background to national security law in the UK, its development, and the constitutional issues to which it gives rise. It covers the work of the intelligence agencies, their oversight, and accountability. It focuses on the main types of executive measures taken by the government on national security grounds, for example, deportation; deprivation of citizenship; refusal of naturalisation; exclusions; the Terrorism Prevention and Investigation Measures Act 2011; the state threats, prevention and investigation measures framework; temporary exclusion orders; and proscription. It covers related legal proceedings, including Closed material proceedings, in specialist tribunals such as the Special Immigration Appeals Commission, the Prescribed Organisation Appeals Commission, and the Security Vetting Appeals Panel, as well as civil proceedings involving national security issues. The book covers sanctions and the increasingly important field of responses to state threats, for example, through measures taken under the National Security and Investment Act 2021, and deals with security issues in the criminal arena, the main offences under the Terrorism Acts and the National Security Act 2023, the approach of the criminal courts to national security matters, the impact of national security issues in inquests and public inquiries, and treatment of national security issues in education, employment, and family law, finally covering freedom of information and data protection.
