The national security trial of Chow Hang-tung and Lee Cheuk-yan, former leaders of the Hong Kong Alliance in Support of Patriotic Democratic Movements of China, represents a structural shift in the city's legal ecosystem. The case, which reached final arguments on May 18, 2026, moves beyond the simple policing of public assemblies. It establishes a judicial precedent regarding the boundary between permissible constitutional advocacy and state subversion under the 2020 National Security Law (NSL).
By dissecting the prosecution's closing arguments and the defense's structural counterpoints, analysts can map the precise mechanics used to recalibrate Hong Kong’s common law system to align with Beijing's sovereign security priorities. The trial moves past historical debates over the 1989 Tiananmen Square crackdown. Instead, it serves as a live test case for how political rhetoric is quantified as a national security threat.
The Prosecution Framework: The Subversion Velocity Vector
The state's case against the defendants rests on a specific interpretation of "inciting subversion of state power" under Article 22 of the NSL. To secure a conviction, the prosecution does not need to prove that physical violence occurred or was imminent. Instead, the legal framework relies on a three-part mechanism to establish guilt:
[Intentionality of Ideological Objective] + [Systemic Incitement Model] = Subversion Velocity Vector
1. Intentionality of Ideological Objective
The prosecution focused heavily on the Alliance’s foundational five-point operational mandate, specifically the core demand to "end one-party rule." The state argues that this phrase inherently targets the constitutional leadership of the Chinese Communist Party (CCP). Under this logic, any advocacy aimed at altering the fundamental state system outlined in Article 1 of the PRC Constitution constitutes an existential threat to the state, regardless of whether the defendants called for explicit revisions to the constitutional text.
2. The Systemic Incitement Model
The state’s argument bypasses traditional common law requirements for a direct, causal link between speech and an imminent lawless act. The prosecution argues that organizing annual candlelight vigils created a predictable, compounding psychological environment. According to this view, decades of public gatherings served as an operational pipeline that conditioned the population to reject the central government’s authority.
3. The Non-Absoluteness Principle
During the closing arguments, prosecutor Ned Lai articulated a strict hierarchy of rights, explicitly stating that the freedoms of speech, assembly, and association are not absolute and cannot function as legal overrides. The state's position is that when individual civil liberties clash with the preservation of the constitutional order, national security must function as the primary legal priority.
The Defense Counterpoint: Constitutional Restraint vs. Structural Reform
The defense strategy, led by lawyer Erik Shum representing Lee Cheuk-yan and Chow Hang-tung defending herself, focused on the absence of a defined mechanism for illegal action. The defense arguments operate within a traditional common law framework, identifying two primary structural flaws in the prosecution's case.
First, the defense highlights an evidential gap regarding unlawful means. The defense argues that the prosecution has failed to identify any specific, unlawful actions that the defendants instructed the public to perform. Under traditional common law standards, incitement requires a clear statement urging an illegal act. The defense contends that advocating for political change through peaceful assemblies and public speeches falls within legitimate constitutional discourse.
Second, the defense relies on a semantic distinction regarding the phrase "one-party rule." The defense argues that calling for an end to one-party rule is an endorsement of democratic transition rather than an attempt to overthrow the state. Lee Cheuk-yan testified that the phrase represents an aspiration for a multi-party system where the populace chooses its leadership, which does not inherently require the forcible removal of the ruling party. Chow Hang-tung argued that her writings were educational, aimed at helping Hong Kong citizens understand mainland political history rather than inciting public hostility.
Judicial Re-engineering and Institutional Divergence
The structural tension in this trial highlights a deeper divergence between two distinct legal traditions within Hong Kong’s judiciary:
- The Classic Common Law Approach: This framework treats civil liberties as structural defaults. Restrictions on rights are treated as narrow exceptions that require the state to meet a high burden of proof, demonstrating a clear, immediate threat of physical harm or systemic collapse.
- The National Security Law Paradigm: This framework treats state security as the foundational prerequisite for all legal rights. Under this model, speech that challenges the ruling party's legitimacy is viewed as a systemic vulnerability that can be restricted before it leads to overt civil unrest.
This systemic shift is further demonstrated by the procedural history of the case. The trial was initially projected to last 75 days but concluded ahead of schedule, following a guilty plea by co-defendant Albert Ho in January 2026. This dynamic reflects the high operational costs and low probability of acquittal that define national security litigation in the current legal environment.
While the Hong Kong Court of Final Appeal recently overturned a separate, lower-level conviction against Chow and other organizers regarding an administrative refusal to provide information to police, that ruling turned on a narrow evidentiary issue about whether the Alliance met the legal definition of a "foreign agent." It does not bind or limit the court’s interpretation of substantive subversion under the NSL in the current trial.
Strategic Forecast
The three-judge panel, operating without a jury in accordance with NSL protocols for state security cases, has deferred its verdict. Given the legal precedents established in previous Hong Kong national security trials, such as HKSAR v. Tong Ying-kit, the court is likely to adopt the prosecution's broader definition of subversion.
If the court rules that peaceful advocacy for systemic political change constitutes subversion, it will formalize a significant change in Hong Kong's legal system. Under this standard, the legal risk for civil society organizations will no longer be determined by whether their methods are peaceful. Instead, risk will be calculated based on whether their stated objectives align with the constitutional frameworks defined by the central government. Organizations operating in Hong Kong will need to evaluate their activities against this standard, as traditional common law protections for political speech will no longer apply to speech deemed a challenge to the state's governance model.
