23rd March 2026 – (Hong Kong) The Hong Kong Special Administrative Region (HKSAR) Government has brought into force new amendments to the implementation rules under Article 43 of the National Security Law, aimed at strengthening enforcement mechanisms and clarifying legal procedures in cases involving national security.
The revised provisions, formally titled the 2026 Implementation Rules for Amending the Implementation Rules for Article 43 of the Hong Kong National Security Law, were gazetted on 23rd March and took immediate effect. The changes were made by the Chief Executive in conjunction with the Committee for Safeguarding National Security, exercising powers granted under Article 43 of the law.
Article 43 permits Hong Kong law enforcement agencies, when handling offences related to national security, to apply investigative powers available for serious crimes under existing local legislation, as well as additional measures specified under the National Security Law. It also authorises the Chief Executive, working with the National Security Committee, to formulate detailed implementation rules. The original rules came into operation on 7th July 2020.
According to the Government, the amendments draw on practical enforcement experience accumulated over recent years, as well as relevant court rulings. Officials said the revisions are intended to refine operational procedures, clarify technical arrangements and expand enforcement tools available to authorities, with the objective of improving the prevention, investigation and handling of national security cases.
A government spokesperson stated that safeguarding national security is an ongoing constitutional responsibility under both the Basic Law and the National Security Law. In light of what officials described as a complex and evolving geopolitical environment, the administration said it must remain vigilant and continue enhancing its legal framework to address potential risks.
The Government emphasised that the amendments comply with the Basic Law, including provisions relating to human rights. It added that the revised rules set out clear conditions governing when law enforcement powers may be exercised and incorporate judicial oversight mechanisms, with the courts acting as gatekeepers for various measures introduced under the amendments.
Officials further said that any new offences created under the updated rules are modelled on existing and commonly recognised offences within Hong Kong’s legal system. The elements of each offence, including intent requirements and available defences, have been clearly defined. Law-abiding residents, the spokesperson said, would not inadvertently breach the law, and the changes would not disrupt daily life or the normal operation of organisations.
