Introduction
The handover of Hong Kong from British to Chinese sovereignty on 1 July 1997 marked a significant constitutional transition. Under the principle of ‘one country, two systems’, the legal framework of the Hong Kong Special Administrative Region (HKSAR) was designed to maintain substantial continuity. This essay examines the mechanisms through which Hong Kong’s existing laws have been preserved, drawing primarily on the Basic Law and related constitutional instruments. It considers both statutory provisions and institutional safeguards while acknowledging emerging tensions in practice.
The Basic Law Framework
Article 8 of the Basic Law explicitly provides that the laws previously in force in Hong Kong—including common law, rules of equity, ordinances, subordinate legislation and customary law—shall remain in force except where they contravene the Basic Law itself (Basic Law, 1997). This provision was intended to ensure legal stability for residents and businesses. In addition, Article 160 authorises the Standing Committee of the National People’s Congress to declare which pre-1997 laws are inconsistent, thereby establishing a formal vetting process rather than wholesale replacement. These articles together create a clear statutory presumption of continuity.
Institutional Continuity and the Judiciary
The continuation of the common-law system is further supported by institutional arrangements. Courts in the HKSAR retain the power of final adjudication, albeit with the possibility of interpretation by the Standing Committee under Article 158. The judiciary has continued to apply English common-law authorities where appropriate, while also developing a distinct Hong Kong jurisprudence. This approach reflects a conscious policy of selective reception rather than wholesale adoption of mainland legal norms. However, critics have noted that the increasing prominence of NPCSC interpretations may gradually erode judicial autonomy over time (Ghai, 2013).
Limitations and Political Realities
Preservation of law is not absolute. National laws listed in Annex III of the Basic Law may be applied in Hong Kong, and the National Security Law enacted in 2020 illustrates how new legislation can be introduced through mechanisms outside the local legislative process. Such developments demonstrate that while the Basic Law provides a robust framework for continuity, its operation remains subject to the overarching sovereignty of the People’s Republic of China. Consequently, the preservation of Hong Kong’s legal system must be understood as conditional rather than perpetual.
Conclusion
Through explicit constitutional provisions, institutional safeguards and selective reception of prior law, the Basic Law has largely succeeded in maintaining Hong Kong’s pre-1997 legal system. Nevertheless, the framework permits modifications that reflect the political realities of ‘one country, two systems’. Understanding these mechanisms remains essential for assessing the long-term resilience of Hong Kong’s legal order.
