Teresa Cheng (1958- )
Teresa Cheng Yeuk-wah is the engineer, barrister and international arbitrator who became Hong Kong's Secretary for Justice: an engineering degree from King's College London and a law degree from the University of London, called to the Bar in 1987, Senior Counsel in 2000, past chairperson of the Hong Kong International Arbitration Centre and the Financial Dispute Resolution Centre, past chairman of the Transport Advisory Committee and the Provisional Minimum Wage Commission, and in 2008 the first Asian woman to serve as President of the Chartered Institute of Arbitrators. On 6 January 2018 she succeeded Rimsky Yuen as the fourth Secretary for Justice, serving until 30 June 2022 — and her first week in office brought the Villa de Mer unauthorised-building-works scandal: she delegated the prosecution decision to the Director of Public Prosecutions, who, on outside independent advice, decided not to prosecute her, one reason being aerial photographs showing the structures predated her purchase; her husband Otto Poon was charged, convicted in 2019 and fined HK$20,000. That December the department decided, without independent outside advice, not to prosecute former Chief Executive Leung Chun-ying in the UGL case, and the Bar Association publicly called it a departure from convention. In 2019 she and Chief Executive Carrie Lam strongly defended the Fugitive Offenders bill and for a time ruled out further changes; the bill triggered territory-wide protests, during which she publicly refused an independent inquiry into police conduct. The department's own figures show 10,242 arrests between 9 June 2019 and 28 February 2021, 2,521 people in judicial proceedings and about 720 charged with rioting; the legal profession twice marched in black alleging selective prosecution and demanding her recusal from protest cases, and she answered throughout with the Prosecution Code and denials of political consideration. This file's attribution standard is stated openly: day-to-day decisions institutionally belong to the DPP and the Prosecutions Division, and verdicts to the courts; but three decisions were hers personally or required her endorsement — the August 2020 intervention terminating Ted Hui's private prosecutions of the Sai Wan Ho shooting officer Kwan Ka-wing and of a taxi driver, the 5 February 2021 Article 46 certificate removing the jury from the trial of Tong Ying-kit, the first national security defendant, and her public defence of the bill and of the national security prosecution system. The National Security Law was promulgated on 30 June 2020 and she described her major responsibility as implementing and safeguarding national security; in January–February 2021 fifty-three democrats were arrested over a primary election and forty-seven charged with conspiracy to commit subversion, the charges issuing from her department. External accountability reached her personally in exactly one place: on 7 August 2020 the US Treasury designated her under Executive Order 13936 for being responsible for or involved in developing, adopting or implementing the National Security Law; no personal listing of her was found in the EU, UK or Canadian lists. After office she returned to arbitration, and on 20 October 2025 became the inaugural Secretary-General of the Hong Kong-headquartered International Organization for Mediation, remaining in post as of October 2026 with no public record of removal from the US list. Two corrections are left on the record: the brief's supposed 2020 decision not to prosecute a Yuen Long officer was searched in English and Chinese and does not exist in the record — the verifiable Yuen Long controversies are the charging tempo for the station attackers and the absence of any reported prosecution of the plainclothes officer who shot a fourteen-year-old in Yuen Long in October 2019; and no record was found of her resigning a UK arbitral post — what is documented is her 2018–2019 clarification of resignations from international investment arbitrations, and her rebuttal, as Secretary, after British judges resigned from the Court of Final Appeal in 2022.
1. Engineer and barrister: from London to Des Voeux Chambers
Teresa Cheng was born in Hong Kong on 11 November 1958. Her education was unusual for the Hong Kong legal profession: she first read civil engineering at King's College London, taking a Bachelor of Science, and then read law at the University of London, taking a Bachelor of Laws; she later held the qualifications of both chartered engineer and chartered arbitrator. She was called to the Bar in England and Wales and in Hong Kong in 1987, in New South Wales in 1990 and in Singapore in 1995, and was appointed Senior Counsel — Hong Kong's successor rank to Queen's Counsel — in 2000. She practised at Des Voeux Chambers, with a practice concentrated in construction disputes, international commercial transactions, joint-venture contracts and investment arbitration: a technical, commercial portfolio with almost no intersection with criminal prosecution, human-rights law or constitutional litigation. That background has to be pinned at the head of the file because it explains two later questions at once: why a government would choose her as Secretary for Justice — for her international arbitration standing and her record in establishment public service — and why, when she faced a constitutional and prosecutorial crisis in 2019, the doubts about her from the start included reservations about her criminal and public-law experience.
From 2011 to 2017 she sat part-time as a Deputy Judge and Recorder in the Court of First Instance of the High Court, a common form of public service for Hong Kong Senior Counsel. Her books include works on construction law and a practical guide to arbitration in Hong Kong, published by Sweet & Maxwell and similar legal publishers. This file records that part of her career separately from her later controversies as a matter of basic discipline: her professional achievements in commercial arbitration rest on a complete international record and are not publicity material; equally, those achievements do not offset her political and prosecutorial responsibility as Secretary for Justice, and neither side of the ledger speaks for the other.

2. The public-service ladder: advisory committees and her arbitration kingdom
Before she became Secretary, Cheng had already spent years inside Hong Kong's advisory and tribunal architecture. On 1 October 2004 she succeeded Jeffrey Lam as chairman of the Transport Advisory Committee, the body that advises the Chief Executive in Council on transport policy. She then chaired the Provisional Minimum Wage Commission, charged with recommending the first statutory minimum wage rate to the Chief Executive; in August 2010 she said publicly that the commission had reached consensus on the level. Around those posts she served as chairperson or member of the Town Planning Appeal Board, the Environmental Impact Assessment Appeal Board Panel, the Appeal Tribunal (Buildings) Panel and the Copyright Tribunal, chaired the Air Transport Licensing Authority, sat on the Construction Industry Council, and chaired the Financial Dispute Resolution Centre — which announced on 29 February 2016 that she had been reappointed chairman of its board for a further two years from 1 March 2016. The common thread of the list is technocratic public service: transport, wages, planning, buildings, financial disputes — none of it touching criminal justice or political controversy. When she explained the building-works scandal in January 2018, she herself reached for this record, saying that at the time she bought the flat in 2008 she had been busy with, among other things, the Minimum Wage Commission and the Transport Advisory Committee; this file records her own placement of that biography in the public record.
In arbitration itself her standing was international. She chaired the Hong Kong International Arbitration Centre, succeeding Huen Wong; she was a vice-president of the International Council for Commercial Arbitration and of the ICC International Court of Arbitration; she was a founder and chairman of the Asian Academy of International Law. In 2008 she was elected, by worldwide election, President of the Chartered Institute of Arbitrators — the first Asian woman to hold that office. She was a member of the ICSID Panel of Arbitrators, designated by the Chairman of the ICSID Administrative Council in 2011 and by China in 2017, and served on the World Bank's Sanctions Board; she sat as arbitrator in investor-state disputes administered by ICSID and the Permanent Court of Arbitration and on ad hoc committees in annulment proceedings. She was a Fellow of King's College London and course director of the International Arbitration and Dispute Settlement Course at Tsinghua University's School of Law. She received the Bronze Bauhinia Star in 2006 and the Gold Bauhinia Star in 2011 for public service. The weight of that arbitration crown matters to this file for one reason: it explains the scale of the reputational fall after 2019. The official who was designated, and who fell among protesters in London, was not a marginal figure — she was the face Hong Kong most often produced when it sold itself to the world as an arbitration centre.

3. The first week in office: the illegal-structures scandal breaks before she is sworn in
On 5 January 2018 Chief Executive Carrie Lam announced Cheng's appointment as Secretary for Justice with effect from the following day, succeeding the retiring Rimsky Yuen. On the eve of her taking office, Ming Pao and Apple Daily reported that her house — No. 4 Villa de Mer, 5 Lok Chui Street, Siu Lam, Tuen Mun — appeared to have an additional staircase leading to unauthorised structures. She held a press conference on 6 January, the day she was sworn in, apologising for the inconvenience caused, admitting she could have been more alert and could have done better, and saying the basement and rooftop structures in question had existed before she bought the property. At the same press conference another fact entered the public record for the first time: the owner of the neighbouring No. 3 house, the engineer Otto Poon Lok-to, was her husband, and his property was also said to contain unauthorised works. Reporting over the following days, confirmed by Buildings Department inspectors, put the total at ten unauthorised extensions across the two properties, including basements and rooftop structures; other reports noted that the mortgage deed she had signed with the bank for the house did not mention the basement. Senior Counsel Lawrence Lok publicly asked her to consider resigning. The Chief Executive's Office said she had informed Lam of the matter on the afternoon of 5 January and had been advised to give an open account as soon as possible.
The archival significance of the episode is not the building detail but the timing and the office: the person found to have unauthorised building works was not an ordinary official but the incoming head of all Hong Kong prosecutions and legal affairs — one who had herself served on the buildings appeal tribunal machinery. At a press session on 10 January a reporter put it to her directly: she had sat on the committee handling buildings appeal cases, so how could she not have known her own home contained illegal structures, and how could the public trust her in the post? She answered that when she bought the property in 2008 it had already been renovated, that she had been busy with projects and community service at the time, that failing to engage an authorised person to inspect before taking possession was an oversight, and that it was not an excuse. On 21 January she further denied knowing the former owner and rejected suggestions of collusion as baseless, and said she had engaged an authorised person to check her other properties. This file fixes only the checkable facts of the episode: the unauthorised works were confirmed by Buildings Department inspection; her apology and explanations are on the press-conference record; the collusion suggestion was unsupported and is not adopted here. The legal outcome follows in the next section.

4. The legal outcome on the structures: she is not prosecuted; her husband is convicted
The way the prosecution question was handled is itself a record of how the Department of Justice deals with a case touching its own head. In early January 2018, to avoid any perception of bias, Cheng delegated to the Director of Public Prosecutions, David Leung, the authority to take all prosecutorial decisions in the matter, including whether anyone should be prosecuted. Buildings Department officers inspected Houses 3 and 4 on 9 January 2018 and identified various unauthorised building works. After investigation and expert advice, the department submitted its file to the Prosecutions Division on 23 November 2018, recommending prosecution of Otto Poon and Karen Poon in respect of House 3 but not of Cheng in respect of House 4. To avoid any perception of bias, the DPP instructed outside Senior Counsel Edwin Choy on 29 November 2018; Choy's finalised advice, received on 19 December, was that there was a reasonable prospect of convicting Poon over the swimming-pool structure at House 3, but insufficient evidence to establish a reasonable prospect of convicting Cheng over House 4 or Karen Poon over House 3. One evidential point was central: aerial photographs from November 2007 and July 2008 showed the House 4 structures had been built before Cheng's company became the registered owner in October 2008. In his statement of 21 December 2018 the DPP adopted that advice: no prosecution of Cheng; Poon was charged before the limitation deadline with knowingly commencing or carrying out building works without approval, contrary to sections 14(1) and 40(1AA) of the Buildings Ordinance.
The second half of the case was played out in court. In April 2019 Otto Poon was convicted: the court ruled that he had knowingly built a swimming pool in his villa's garden without the government's approval, that the pool was a sizeable structure requiring prior permission, and he was fined HK$20,000 — the fine as discussed in the South China Morning Post's editorial on the sentence, which also noted that the other unauthorised structures at his house had been rectified and that, as an engineer, he ought to have known where the legal lines ran. This file's attribution for the whole episode is precise: the decision not to prosecute Cheng was not hers — she had delegated the authority, and the decision was taken by the DPP on outside independent advice, with its evidential reasoning published in a public statement. But the political account settled on her name anyway: a Secretary for Justice whose first week in office was consumed by her own illegal structures, and who needed a full recusal apparatus to clear herself, began the job with her stock of public trust already rewritten. University polling gives the measure: in November 2018 her rating among the three secretaries was 40.9, the lowest of the three; by July 2021 it had fallen to 23.3; on the eve of her departure in May 2022 it was 29.0. The figures are the polling institute's and are cited here as a record of standing, not of fact about any case.

5. The UGL decision: the precedent controversy over outside legal advice
On 12 December 2018 the Department of Justice announced its decision not to prosecute Leung Chun-ying — former Chief Executive and a vice-chairman of the Chinese People's Political Consultative Conference — over the UGL matter. The announcement was made while Cheng was on leave, and the manner of it became part of the controversy. The focus of the row was not the evidential assessment itself but procedural convention: in past cases involving senior officials and perceived political sensitivity, the department's established practice had been to obtain advice from counsel independent of the department; this time it had not. The Hong Kong Bar Association's statement of 21 December 2018 noted that the decision had been reached without the benefit of any independent counsel's advice, called the failure to obtain it a departure from a commendable and well-recognised convention, and said the departure raised justifiable doubts as to whether the decision had been reached free of bias or political considerations — particularly given Leung's position as a CPPCC vice-chairman. The association urged the department to review the decision after obtaining independent advice, while reaffirming that under Article 63 of the Basic Law prosecution decisions must be made independently and must be fully seen by the public to be made independently.
Cheng's answer is on the record of a media session. At Hong Kong airport on 26 December 2018 she said the department's policy was to make prosecutorial decisions within the department itself, and that outside counsel would not be engaged unless the case involved a member of the department; she declined to comment on the specific case, said the press release of 12 December had set out everything that could professionally be told to the public, and added that the Department of Justice dealt only with legal issues and that political issues had nothing to do with it. The Bar Association later put its concerns in writing to the Legislative Council, proposing that the Secretary explain her decision-making process — in particular when external advice would be sought — and establish protocols with the Director of Public Prosecutions so that the Secretary concerned herself in decision-making only in the most exceptional cases. This file's fixing of the episode is procedural: the substantive merits of not prosecuting Leung were never set out by the department in detail, and this file does not adjudicate them. What is checkable is that a convention was broken, that the legal profession's peak body objected in public, and that the Secretary chose to answer by normalising in-house decision-making. The section sits before the extradition crisis in this file because it set the template of the question that would recur for three years: when the person concerned is at the most politically sensitive level, is the department's process visibly separate enough from politics? The prosecution-tempo disputes of 2019 and the private-prosecution intervention of 2020 are continuations of the same question.

6. The 2019 bill: the draft she stood in front of
In February 2019 the government introduced into the Legislative Council the Fugitive Offenders and Mutual Legal Assistance in Criminal Matters Legislation (Amendment) Bill, which would have allowed case-based surrender of fugitives to places with which Hong Kong had no long-term arrangement, including mainland China, Macau and Taiwan. The legal design came from the Department of Justice and the Security Bureau, and the public defence was shared by Chief Executive Carrie Lam, Secretary for Security John Lee and Secretary for Justice Teresa Cheng. After the legal profession, business groups, journalists' organisations and foreign governments had voiced their concerns in succession, Cheng and Lam nonetheless strongly defended the measure and for a time ruled out further changes — a posture recorded by the Committee to Protect Journalists in May 2019, citing news reports. Reporting on her London fall months later, the South China Morning Post described her directly as considered a key figure in the drafting of the now-shelved bill; Agence France-Presse likewise reported that protesters saw her as playing a key role in pushing it forward. On 9 June 2019 crowds estimated from the hundreds of thousands to over a million marched against the bill; on 12 June clashes outside the Legislative Council left dozens injured; on 15 June Lam announced the bill's suspension, and after an even larger march on 16 June the government issued an apology. One documented personal position of Cheng's from the crisis is this: she publicly ruled out an independent inquiry into police conduct — one of the protesters' five demands — as reported by the BBC and carried by news agencies, a position this file records on that sourcing; in her official blog she wrote that the government promised to adopt a most sincere and humble attitude in accepting criticism and making improvements.
The bill's end must be recorded completely: on 4 September 2019, after thirteen weeks of protest, Lam announced the government would formally withdraw the bill when the Legislative Council resumed; on 23 October Secretary for Security John Lee formally withdrew it in the Council. The withdrawal was therefore not announced by Cheng — but the bill's whole course, from proposal through defence to shelving, ran within her tenure as the government's chief legal officer, and public memory binds her to it on two hard pieces of evidence. First, at the second silent march of the legal profession on 7 August 2019, one demand of the roughly three thousand lawyers was that she keep completely away from prosecution decisions arising from the protests, because as one of the principal officials responsible for pushing the bill she had a conflict of interest. Second, when protesters surrounded her in London that November, the slogans shouted at her included the five demands and 'murderer', and reporting consistently traced the anger to her role in the bill. Attribution stops there: the policy decision belonged to the Chief Executive and the government as a whole, and the legislative process to the Council. Her personal share is that, as chief legal officer, she supplied the bill's legal endorsement, defended it strongly in public, and refused to answer the police-brutality allegations with an independent inquiry.

7. The volume of protest prosecutions: the numbers, nailed to the page
The hardest evidence of prosecution posture is the government's own published figures. On 8 April 2021, answering Legislative Council questions, the Department of Justice disclosed that between 9 June 2019 and 28 February 2021 a total of 10,242 people had been arrested in connection with the social unrest, of whom 2,521 had undergone or were undergoing judicial proceedings. Security Bureau figures put about 720 of the 2,521 as charged with rioting, the rest with offences including unlawful assembly, arson and insulting the national flag. Of the 2,521, 883 had to bear legal consequences — 614 convicted, 261 bound over, four made subject to care or protection orders and four punished in civil contempt proceedings; the charges against another 50 had been withdrawn and 186 had been acquitted after trial, with the remainder still in process. The division of responsibility for these figures must be written plainly: arrests were made by the police; the decision to charge was the department's, taken on evidence, law and the Prosecution Code; convictions and acquittals were the courts'. This file cites the figures to establish one thing only: that on her watch as Secretary, the department put more than two thousand five hundred arrestees into judicial proceedings, and used the charge of rioting — an offence carrying up to ten years' imprisonment — about seven hundred and twenty times. The scale of the rioting charge is the figure most often cited by critics of the prosecution posture, and it comes from the department's own formal submission to the legislature, not from opposition counting.
Human Rights Watch's later cumulative figures give the wider frame, but must be placed within their own time range. Reviewing the position in 2024, Human Rights Watch cited government figures of more than 10,000 protest-related arrests, 2,910 people prosecuted and 1,475 convicted — cumulative totals to 2024, including two years of progress after Cheng left office; this file records them as cumulative and does not charge the post-tenure increment to her tenure. The cross-section that can be nailed to her tenure is the official February 2021 set above. One further item belongs here for completeness: the department never published a symmetric statistical table for prosecutions of police officers or of attackers of protesters over the same period, and the absence of any comparable official series is the soil in which the asymmetry dispute of the next sections grew. This file does not estimate a police-prosecution figure of its own, because no comparably based official number exists in the public record; the item is recorded as no published statistics.
Sources: Department of Justice and Security Bureau papers to the Legislative Council, 8 April 2021, as reported by Xinhua and the South China Morning Post on 9 April 2021 (10,242 arrested; 2,521 in judicial proceedings; about 720 charged with rioting; 883 bearing legal consequences; 614 convicted; 50 withdrawn; 186 acquitted after trial); Human Rights Watch, five-year review, 2024, citing cumulative government figures (2,910 prosecuted; 1,475 convicted), recorded here as cumulative.
8. The selective-prosecution charge and her denials
The Hong Kong legal profession held two silent marches in black, on 6 June and on 7 August 2019; the second drew around three thousand participants. The charges made on 7 August were specific. Legal-sector legislator Dennis Kwok put two public questions: whether the department's recent prosecutorial decisions were politically motivated, and why the assailants who had attacked citizens at Yuen Long station had yet to be prosecuted while young protesters were already charged with rioting. The marchers demanded an independent unit within or outside the department to handle protest-related prosecutions, and demanded that Cheng keep completely away from charging decisions, on the ground that as a principal official responsible for pushing the bill she had a conflict of interest. Kwok also said on a radio programme that day that the Director of Public Prosecutions, David Leung, had proposed an independent prosecution committee for protest cases and had been overruled by Cheng; the department responded that the report was totally unfounded and that Cheng and Leung were deeply disappointed by it. Cheng did not come out to meet the marchers. This file labels the layers separately: the march and its charges are matters of published reporting; the claim about Leung's proposal rests on Kwok's account alone and was denied by the department, and is marked unverified, with only the existence of the dispute recorded; the conflict-of-interest charge is the legal profession's professional and political judgement, recorded as a charge, not adopted as a finding.
Cheng's formal answer to the political-prosecution charge exists in the department's press-conference transcripts as a fixed formula, which can be set out point by point. She emphasised repeatedly that there was absolutely no political consideration in the department's prosecutorial decisions; that her Prosecutions Division colleagues applied the two-stage test of the Prosecution Code — first, whether the evidence afforded a reasonable prospect of conviction, and second, if so, whether prosecution was in the public interest; and that suggestions of political consideration were absolutely groundless. She restated the same formula in connection with the prosecution decisions in the case of the seven police officers, among others. This file places the charge and the answer side by side not to adjudicate between them here, but because the exchange constitutes the core dispute over prosecutorial legitimacy in her tenure: the volume and tempo of the charges are in Section 7, the specific content of the criticism and her own answers are in this section, and the reader can set them against each other. One procedural fact the file can confirm: she never accepted the legal profession's structural proposals — no independent prosecution unit was created, and she made no public announcement recusing herself from protest-case decisions. Her chosen mode of response was to repeat the Prosecution Code and deny all political consideration. That choice was itself a decision of hers as Secretary, and is recorded as such.
Sources: South China Morning Post, 7–8 August 2019 (the second silent march of about 3,000 legal professionals; Kwok's two questions; the demands for an independent unit and for Cheng's recusal; the department's 'totally unfounded' response on the independent-committee report); Department of Justice media transcripts (Cheng's statements that prosecutorial decisions involved absolutely no political consideration and followed the Prosecution Code's two-stage test of evidence and public interest, and that the political-consideration suggestion was groundless).
9. Yuen Long: the origin of the asymmetry dispute — and a claim that does not check out
Yuen Long has to be written in two halves in this file: a documented dispute, and a claim that must be corrected. The documented half is this. On the night of 21 July 2019 a crowd of men in white shirts attacked passengers and citizens indiscriminately at Yuen Long station, injuring dozens. By the legal profession's march of 7 August, published reporting put the position as follows: twenty-four men had been arrested for unlawful assembly over the Yuen Long incident and none had yet been charged, while forty-four people arrested over the Sheung Wan protest a week after Yuen Long had already been charged with rioting. That time-lag became the most frequently cited instance in the selective-prosecution charge, and it comes from the South China Morning Post's reporting of the march and the marchers' public statements. Thereafter the Yuen Long prosecutions proceeded step by step and some assailants were charged and convicted by the courts; those are court outcomes, which this file does not itemise case by case and, again, does not attribute to the Secretary. A second Yuen Long shooting is also on the public record: on 4 October 2019 a plainclothes officer shot a fourteen-year-old boy in the left thigh in Yuen Long; the boy was later sentenced by a court to a training centre and given a criminal record. No public report was found of that officer being prosecuted. That is the whole of what can be verified on the Yuen Long line.
The half that must be corrected is this. The brief for this file referred to a supposed 2020 Department of Justice decision not to prosecute a Yuen Long officer. This file searched the public record in both English and Chinese and found no decision, statement or report of any 2020 departmental decision not to prosecute a named Yuen Long officer. The verifiable Yuen Long prosecution controversies are the two items above — the charging tempo for the station attackers, and the absence of any reported prosecution of the officer who shot the fourteen-year-old — not a citable 2020 decision. To write an unverifiable claim into the archive would manufacture a decision that does not exist in the record, and this file expressly does not do so; the correction is left here on the page: the brief's item appears to be a misremembering or a conflation with another case. The closest real case is the subject of the next section — the Sai Wan Ho shooting officer's private prosecution, which was in 2020, and whose termination was decided by Cheng herself.
Sources: South China Morning Post, August 2019 (twenty-four arrested and none charged over Yuen Long against forty-four charged with rioting over Sheung Wan, in its reporting of the legal profession's march); court reporting carried in the timeline of reactions to the 2020 Hong Kong national security law (the 4 October 2019 Yuen Long plainclothes shooting of a fourteen-year-old; the boy's training-centre sentence and criminal record); the absence of any 2020 'Yuen Long officer' non-prosecution decision is this file's bilingual search result across public sources as of October 2026, recorded as no public record and corrected in the text.
10. The private prosecutions stopped: August 2020, an intervention over her own office's name
This is the least contestable attribution in the whole file, because the decision documents carry her own office in their text. On 11 November 2019 a traffic police officer, Kwan Ka-wing, shot a twenty-one-year-old man, Chow Pak-kwan, in Sai Wan Ho while dealing with road-blocking during the protests; Chow was himself later prosecuted. On 23 January 2020 legislator Ted Hui filed a private criminal prosecution against the officer, charging him with attempted murder or, alternatively, shooting with intent to cause grievous bodily harm — offences carrying up to life imprisonment. A court in due course issued the summonses, and the private prosecution was under way. Hui also brought a private prosecution over an October 2019 incident in which a taxi driver drove into a crowd in Sham Shui Po, injuring two women. In June 2020 Cheng pre-announced her position on her official blog: she would end any private prosecutions that were groundless or frivolous, or brought out of improper motives or political considerations. On 18 August 2020 Hui made public that he had been informed by the Department of Justice that the Secretary for Justice, Teresa Cheng, had decided to intervene. The department's letters to the court, copies of which Hui's party released, stated that the Secretary of Justice had intervened and assumed the conduct of the proceedings under the Magistrates Ordinance, requested an early mention date before 31 August for the prosecution to withdraw the summonses, and added that the department did not require the attendance of the defendant officer. Hui said the department had provided no reasons or legal basis for the decision, called it the blatant overriding of the rule of law by rule of man and a condoning of police violence, and said he would consider a judicial review; the department responded that, the case being in judicial proceedings, it was not suitable to comment.
The end came on 24 August 2020, when the West Kowloon Magistrates' Court granted the department's request and discontinued both private prosecutions. The department's reasoning, as later reported and analysed, was that after reviewing investigation reports from an independent police team it considered that the officer had used lawful and reasonable force for crime prevention and self-defence, that neither case showed a reasonable prospect of conviction, and that the defendant's right to a fair trial would be impaired because Hui did not plan to call witnesses including the man who had been shot. Spectators in the public gallery heckled the prosecutors; Hui said outside court that he was disappointed by the ruling and extremely furious about the department's intervention and termination of the cases. Former Director of Public Prosecutions Grenville Cross observed publicly that, given Article 63 of the Basic Law, under which the department controls prosecutions free from interference, a court was unlikely to be able to overrule the decision. This file fixes three points. First, intervening in a private prosecution is a lawful power of the Secretary for Justice, and exercising it was not in itself unlawful. Second, this exercise of it was a named personal decision: the letters issued in the terms that the Secretary had intervened and assumed conduct, and the blog warning that preceded it was hers. There is no institutional-versus-personal blur here. Third, its effect was to close, before any public hearing, a prosecution against a shooting officer that had already passed the court's threshold for issuing summonses. From that point on, the private prosecution — the citizen's route around the department to hold an officer to account — stood demonstrated in practice to be closable at the Secretary's hand at any time. That is the structural fact this case left inside Hong Kong's criminal justice system.

11. The National Security Law arrives: she sits on the committee; prosecutions sit in her department
On 30 June 2020 the Standing Committee of the National People's Congress passed the Law of the People's Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region and, the same night, it was listed in Annex III of the Basic Law and promulgated in Hong Kong, bypassing the Legislative Council's own legislative process. The law created a Committee for Safeguarding National Security chaired by the Chief Executive, of which the Secretary for Justice is a statutory member; the committee's work is not made public and its decisions are not amenable to judicial review — institutional arrangements taken from the law's own text, recorded here as such. Cheng's public account of her own role under the new law comes in two sets. The first is procedural assurance: on 6 June 2020 she said on a radio programme that, under Article 63 of the Basic Law, the Department of Justice was responsible for all criminal prosecutions without interference, that national security cases would likewise be decided by the department on the evidence, the law and the Prosecution Code, with enforcement agencies passing the file to the department for handling in the normal way; later that month she assured the South China Morning Post and radio audiences that her department's national security prosecution decisions would be made independently, free of interference from mainland authorities, and that evidence from mainland enforcement agencies would be vetted under standard court procedures. The second is a statement of identity: the US Treasury's August 2020 designation notice recorded that, as head of the Department of Justice, Teresa Cheng had said her major responsibility was implementing and safeguarding national security in the HKSAR — and Treasury used that self-description as part of its basis for finding her responsible for or involved in developing, adopting or implementing the National Security Law. Set side by side, the two sets are her complete self-positioning under the new law: to Hong Kong audiences, an emphasis on prosecutorial independence; in the context quoted by the sanctions notice, the implementation of national security placed first among her duties. This file does not reconcile the two for her; it nails both to the page.
The first case under the law opened within her tenure. On 1 July 2020 Tong Ying-kit rode a motorcycle into police officers in Wan Chai with a flag reading 'Liberate Hong Kong, revolution of our times' mounted behind him. On 3 July the government issued a statement that the slogan connoted Hong Kong independence or subversion, and the same day Tong was charged with terrorist activities and inciting secession under the National Security Law — the first person charged under it. On 6 July a court refused him bail under Article 42 of the law. The charging decision belonged to her department and the bail ruling to the court, and this file records them on that division. By the time she left office in June 2022, national security prosecutions had expanded to the primary-election case, the Jimmy Lai and Apple Daily matters and a series of sedition cases, itemised in the next two sections. On volume, the department published no single cross-section of national security prosecutions within her tenure, and this file does not compile one of its own; the item is recorded as no published statistics.

12. The Tong Ying-kit certificate: the no-jury decision that bears her signature
Article 46 of the National Security Law empowers the Secretary for Justice to issue a certificate directing that a case be tried without a jury — on grounds including the protection of state secrets, the involvement of foreign factors, or the personal safety of jurors and their families — whereupon the case is tried by a panel of three designated judges. On 5 February 2021 Cheng exercised that power in the case of Tong Ying-kit: she issued a certificate directing that his trial be heard by three judges appointed for national security cases instead of a jury, citing the personal safety of jurors and their family members and adding that there was a real risk the due administration of justice might be impaired if a jury trial were allowed. It was the first time since the establishment of the jury system in Hong Kong that a High Court criminal trial was stripped of its jury by administrative certificate — and the issuer of the certificate was an executive official, not a judge. That institutional fact is the core attribution point of the case: the decision was hers personally, and there is no one else to share it. Tong then sought judicial review of the certificate.
The review's outcome belongs to the courts, and this file records only the procedure and the decision-makers. On 20 May 2021 Judge Alex Lee of the Court of First Instance dismissed the judicial-review application, holding that there was nothing inherently unreasonable in directing trial by a panel of three judges without a jury where the safety of jurors and the due administration of justice were perceived to be at risk; the US Congressional-Executive Commission's analysis records the further holding that the Secretary's power to issue the certificate was a sole discretion, unreviewable save in narrow circumstances. On 22 June 2021 the Court of Appeal upheld the denial of a jury trial; on 23 June Tong's trial opened. The conviction and sentence that followed were the acts of the three judges, and under this file's standing discipline they are not attributed to Cheng. Her personal responsibility stops at the certificate itself — but that is a large place to stop: by a single administrative instrument she decided that the first national security trial would have no jury, and set the precedent for the certificates that followed in later national security cases. Once that precedent existed, trial without jury became the standard arrangement for national security cases in the High Court, and its originating decision is in this case, in this certificate, in her hand.

13. The primaries case and the widening of national security prosecution: forty-seven charged
In the early morning of 6 January 2021, national security police arrested fifty-three pro-democracy figures for organising or participating in the July 2020 primary elections held by the democratic camp to select candidates for the Legislative Council election, alleging offences under the National Security Law. The operation searched seventy-two sites, including the home of the jailed activist Joshua Wong, the offices of Apple Daily, Stand News and Hong Kong Inmedia and the Hong Kong Public Opinion Research Institute, and froze more than HK$200,000 in funds connected with the primaries. It was the largest single arrest operation under the law since its passage. On 28 February 2021 forty-seven of those arrested were formally charged with a single count of conspiracy to commit subversion, and appeared in the West Kowloon Magistrates' Court the next day, with hundreds of supporters gathering outside. Those charged included the legal scholar Benny Tai, former legislators, district councillors, social workers and young activists. The prosecution's core allegation was that the primary plan — to win a legislative majority, veto the budget and thereby force the Chief Executive's resignation — amounted to subversion of state power. The decision to charge was the Department of Justice's, an institutional decision; the trial and its verdicts ran for years beyond her tenure, and this file does not record post-tenure outcomes. It fixes only the two nodes that fall within her service: the arrests in January 2021 and the charges in February 2021, with the charge sheets issuing from the department she headed.
The primaries case's significance within her tenure is best seen against the whole widening of national security prosecution: from Tong Ying-kit alone in July 2020 to forty-seven co-defendants in February 2021, the law's prosecutorial reach extended from street confrontation to peaceful political participation conducted through electoral and parliamentary procedure, and its charges from terrorist activities to a conspiracy-to-subvert theory encompassing a primary election — a routine instrument of candidate selection in democratic systems. This file's attribution for that widening remains layered: the arrests and searches were police operations; the choice of charges and the decision to prosecute were institutional decisions of the department, executed by the Prosecutions Division, with the Secretary bearing the departmental head's institutional responsibility; her personal public role was the continuing defence of the national security prosecution system — for example on 30 March 2022, after the President and Deputy President of the UK Supreme Court resigned as non-permanent judges of the Court of Final Appeal, she issued a statement as Secretary rebutting claims that the Chief Executive could handpick judges for national security cases, calling the accusations baseless and factually incorrect and saying designation merely established a panel, while listing, assignment and handling of cases remained functions of the judiciary exercised independently. That statement, three months before she left office, is on the government record.

14. London and the British questions: a fall, resigning judges, and a resignation claim that must be clarified
On the evening of 14 November 2019, on her way to deliver a keynote lecture at the Chartered Institute of Arbitrators in London, Cheng was surrounded for several minutes by dozens of protesters shouting slogans including 'five demands, not one less' and 'murderer'. In the crush she fell to the ground and injured her arm, and was taken to hospital by ambulance. Her office issued a statement that night castigating the violent mob in London for causing her serious bodily harm, and said she had reported the matter to the London police and asked them to take the case seriously and bring the culprits to justice. The Chartered Institute of Arbitrators said she had been assaulted by a crowd while entering the building. The Metropolitan Police said they were investigating an allegation of assault and that no arrests had yet been made; the circulating video footage did not make clear whether she had been pushed or had fallen — the BBC's reporting states that point expressly, and this file records it on that basis without completing the picture for either side. Chief Executive Carrie Lam condemned the incident as barbaric; a Chinese foreign ministry spokesman said it was directly related to British politicians confusing right and wrong on Hong Kong and supporting violent acts. It was the first physical confrontation involving a cabinet member since the unrest began — and it happened at an event where she appeared in her arbitration capacity, promoting Hong Kong as a dispute-resolution centre. Her two identities, extradition-bill secretary and arbitration ambassador, collided on a London street.
Two further British items require disentangling. First, the brief for this file referred to her resigning from a United Kingdom tribunal or chartered-arbitrator post. This file's search found no record of her resigning any post in a United Kingdom institution. What is documented is a different set of resignations: on taking office she resigned her arbitral appointments, including, on 7 February 2018, the presidency of an ICSID tribunal in a case one of whose treaties in issue was the United Kingdom–Romania bilateral investment treaty; the tribunal was reconstituted on 5 April 2018. And on 24 May 2019 she clarified publicly that, of the cases she had been handling when appointed, six had been approved by the Chief Executive for her to complete the awards and orders then in hand, whereupon she resigned from them immediately on completion, while in all other cases — including the three ICSID cases that reporting had suggested she had not resigned — she had already resigned. Second, the genuine Anglo–Hong Kong judicial controversy came on 30 March 2022, when Lord Reed and Lord Hodge resigned as non-permanent judges of the Court of Final Appeal and the British government said it was no longer tenable for serving UK judges to sit on it; Cheng answered the same day, as Secretary, with the rebuttal of the handpicked-judges claim recorded in the previous section. Kept separate, the British record is clear: she has no resignation from a British post; what exists is her being surrounded and injured by protesters in London, her clarified resignation of international investment-arbitration appointments, and her official rebuttal, as Secretary, of the British judges' departure.

15. The sanctions check: designated by the United States; no listing found in the UK, EU or Canada
On 7 August 2020 the United States Treasury announced that, under Executive Order 13936 — 'The President's Executive Order on Hong Kong Normalization', signed by President Trump on 14 July 2020 — it was sanctioning eleven individuals for undermining Hong Kong's autonomy and restricting the freedom of expression or assembly of its citizens. Cheng was designated together with Carrie Lam, Chris Tang, Stephen Lo, John Lee, Erick Tsang, Xia Baolong, Zhang Xiaoming, Luo Huining, Zheng Yanxiong and Eric Chan, and placed on the Specially Designated Nationals and Blocked Persons List. Treasury's release gave a named paragraph for each designee. For Teresa Cheng it read, in substance: she is the Secretary for Justice of Hong Kong; as head of the Department of Justice she has said that her major responsibility is implementing and safeguarding national security in the HKSAR; she is designated for being responsible for or involved in developing, adopting, or implementing the National Security Law. Treasury Secretary Steven Mnuchin said in the same release that the designees had implemented policies directly aimed at curbing freedom of expression and assembly and democratic processes, and were responsible for the degradation of Hong Kong's autonomy. The legal consequences are stated in the same document: all property and interests in property of the designees in the United States, or in the possession or control of US persons, are blocked and must be reported to OFAC, and US persons are generally prohibited from transactions involving them. On 14 October 2020 the Secretary of State's report to Congress under Section 5(a) of the Hong Kong Autonomy Act again named ten individuals, Cheng among them, as materially contributing to China's failure to meet its obligations under the Joint Declaration and the Basic Law; OFAC's own guidance confirms that the persons named in that report were the same individuals designated on 7 August, and that the report itself imposed no new blocking.
The other jurisdictions were checked one by one, and the conclusion is a blank, recorded as a blank. United Kingdom: a parliamentary question answered on 28 April 2022 confirmed that there were then no Hong Kong citizens designated under the UK's Global Human Rights sanctions regime, and that it was not appropriate to speculate on future designations; Hong Kong Watch's sanctions briefing likewise records that, despite the United States having sanctioned Hong Kong officials, the UK has still yet to sanction any Hong Kong officials — the briefing's purpose is to urge UK sanctions, and this file takes from it only its statement of the existing position. European Union: the EU's response to the National Security Law was a diplomatic package of measures and support for civil society; the European Parliament repeatedly adopted resolutions urging the Council to use the EU Global Human Rights Sanctions Regime against Hong Kong officials, but a resolution is a political call, not a listing decision, and as of October 2026 this file found no EU decision listing Teresa Cheng. Canada: Canada's March 2021 sanctions against China under the Special Economic Measures Act concerned human-rights violations in Xinjiang, and their lists named Xinjiang officials and an entity; this file found no record of Canada listing Cheng or any Hong Kong official, Canada's Hong Kong measures having taken the form of immigration facilitation and suspension of extradition arrangements rather than personal designations. Her assets abroad are a matter of no public record; beyond the designation itself, the practical personal effects of the US sanctions — for example on her international arbitration practice or banking — are not documented publicly, and this file does not speculate.

16. After office: arbitration, rare public words, and the Secretary-Generalship of the International Organization for Mediation
Cheng's term ended on 30 June 2022 with the rest of the Carrie Lam administration; Paul Lam succeeded her as Secretary for Justice. She returned to her original trade — international arbitration and mediation practice — remaining on the ICSID Panel of Arbitrators and holding posts including an adjunct professorship at Tsinghua University and the co-chairmanship of the Asian Academy of International Law. Since leaving government she has rarely commented publicly on Hong Kong politics, a point the South China Morning Post noted expressly when reporting her remarks in June 2024 on the resignation of two further British judges, Lord Collins and Lord Sumption, from the Court of Final Appeal: she told the paper the departures would not affect judicial independence, that the quality of the appellate mechanism depended on the ability, experience and commitment to the rule of law of the bench rather than on nationality, and that with nearly twenty-seven years of its own independent Court of Final Appeal, Hong Kong's rule of law would continue to be upheld under the Basic Law. That intervention is continuous with her positions in office: she has never publicly revised her defence of the National Security Law or of the designated-judge system, and this file records the continuity on the basis of her 2024 statements.
Her largest post-office role came in 2025. On 30 May 2025 the signing ceremony for the Convention on the Establishment of the International Organization for Mediation was held in Hong Kong, with thirty-three states signing; the convention entered into force on 29 August 2025. On 20 October 2025 the organisation — headquartered in the Old Wan Chai Police Station — held its inauguration, and its Governing Council, chaired by Hua Chunying, appointed Teresa Cheng its inaugural Secretary-General and Sun Jin its Deputy Secretary-General; there were then eight contracting states. The IOMed describes itself as the first intergovernmental legal organisation dedicated to settling international disputes through mediation, with a mandate covering disputes between states, between a state and foreign investors, and international commercial disputes. In October 2026, in Vienna, she marked its first anniversary: the signatory or acceding states had grown to forty-eight, with eighteen contracting states, and the organisation had handled several cases, including a China–Singapore maritime dispute settled after a single day's mediation. As of October 2026 she remains in that post, which is her current office. There is likewise no public record of her removal from the US Specially Designated Nationals list. A person blocked by one legal order for implementing the National Security Law now heads, by appointment, an international organisation championed by the other: that contrast, and not any gloss upon it, is the single most record-worthy line of her post-office biography, and this file records the contrast and leaves the judgement to the reader.

17. Our Take: four and a half years of the chief legal officer
The Teresa Cheng file is this site's specimen of a particular form of responsibility: how a technocratic legal official becomes the load-bearing wall of the legal side of a political suppression. Our Take rests only on facts verified in the body of this file, in three points.
First, her responsibility is not located in court verdicts but in the institutional decisions that determined how verdicts would come to be reached. This site does not charge her with any case's conviction or sentence — those are judges' decisions — nor with the arrests, which were the police's work. But three things carry her name or her office's signature. The legal endorsement and public defence of the extradition bill: she stood beside the Chief Executive to sell a law that would have sent Hong Kong people to face trial on the mainland, and in the crisis refused an independent inquiry into the police. The August 2020 intervention terminating the private prosecutions: a prosecution of a shooting officer that had already obtained summonses from a court was shut down before trial by her authority as Secretary. And the February 2021 Tong Ying-kit certificate: the first national security trial's loss of its jury was effected by her administrative instrument, not by a judge's ruling. These three decisions share one feature: none of them was routine case-handling by the Prosecutions Division; each was a decision only the Secretary could take, or that had to carry the Secretary's endorsement. If attribution stops at collective nouns — the system, the department, the division — these three decisions are left unclaimed. This file nails them back, item by item, to her name, and that is the reason this page exists.
Second, the most durable damage of her tenure was done to the credibility of prosecution itself, and much of it by her own choices about process. In the building-works case the full apparatus of recusal and outside independent advice was run, and the decision not to prosecute her rested on published evidential reasons. In the UGL case the same apparatus was set aside, the decision was taken without independent advice, and the Bar Association warned in public that the departure would shake confidence in the criminal justice system. Set side by side, the problem was never any single decision's rightness or wrongness; it was the rule she demonstrated to the public — that procedural safeguards were complete where she herself was concerned, and could be simplified where a former Chief Executive at a higher political level was concerned. The selective-prosecution controversy after 2019 was the same logic enlarged: when three thousand lawyers marched to demand her recusal from protest cases, and when the charging-tempo gap between the Yuen Long attackers and the Sheung Wan protesters was in the newspapers, her response was to repeat the Prosecution Code and deny political consideration — no independent mechanism was created and no comparable statistics were published. A Secretary for Justice may lawfully hold prosecutorial power free from interference; but the legitimacy of that power depends on its decisions being seen to be fairly made. On the 'being seen' element, her tenure operated at the minimum.
Third, external accountability in her case, and its limits, must be kept at their true levels. The United States designated her in August 2020 for implementing the National Security Law — to date the only personal, legally consequential foreign sanction against her, with its stated basis nailed to Section 15 of this file. The United Kingdom, the European Union and Canada did not follow with listings of their own, and European Parliament urgings and British campaign briefings are not sanctions; this file does not write them as sanctions. The account kept by China and the Hong Kong government runs on another line: she completed her term undisturbed and, after office, was appointed the inaugural Secretary-General of an international organisation established on China's initiative. Blocked by one legal order and entrusted with an international organisation's leadership by the other, her post-office trajectory writes the fork in Hong Kong's legal order after 2019 into a single person's biography. What an archive can do is fix, item by item, the instruments she signed, the platforms she stood on, the words she said and the sanction she incurred — and leave them alongside the blanks: no independent inquiry, no prosecuted shooting officer, a first trial without a jury — for those who come after.
Sources: This section is this site's evaluation, based on the facts sourced in the body: Sections 4–5 (the process contrast between the building-works and UGL decisions), Sections 6–9 (the bill's defence, the prosecution figures and the selective-prosecution dispute), Section 10 (the private-prosecution intervention), Section 12 (the no-jury certificate), Section 15 (the US designation and the UK, EU and Canada blanks), Section 16 (her departure and the IOMed appointment).
