National Security

19 cases · February 2021 to February 2026

Overview

National Security appears in 19 reported Hong Kong judgments (2021–2026).

Cases under Hong Kong's national security laws, including secession, subversion and sedition charges.

National-security cases in Hong Kong concern offences and proceedings under the territory's national-security legal framework. The framework comprises the National Security Law, the locally enacted Safeguarding National Security Ordinance, and offences such as sedition, together with the procedural arrangements that govern bail, the composition of the court and the conduct of trials. Charges in this field include secession, subversion, terrorist activities, collusion with external forces and seditious acts, and the cases frequently raise questions about the interaction of the framework with rights protected by the Basic Law and the Hong Kong Bill of Rights.

These matters are prosecuted through the criminal courts. Trials may be conducted in the District Court or, for the most serious charges, in the Court of First Instance before designated judges. Appeals against conviction and sentence are heard by the Court of Appeal, and questions of law of great and general importance are determined by the Court of Final Appeal, which sits at the apex of the judicial system.

The reported authorities set out the developing principles. The Court of Final Appeal has addressed bail and interpretive questions in [2021] HKCFA 3 and [2024] HKCFA 25, while first-instance rulings appear in [2024] HKCFI 3298 and [2024] HKCFI 553. Appellate guidance on national-security and related public-order offences is found in [2024] HKCA 231 and [2024] HKCA 442. These judgments record how the framework has been construed and applied by the courts.
