SENTINEL DEFENDERS BRIEFING
Human rights developments through the lens of defender protection, justice and accountability.
Issue #001 | 12 October 2026
Editor’s note
This issue begins with developments affecting Hong Kong people: prosecutions concerning speech and disclosure, a court decision upholding an acquittal, and a change to settlement rules for BN(O) families in the United Kingdom.
We then turn to alleged surveillance in Taiwan, China’s expanding travel restrictions and the imprisonment of artist Gao Zhen.
Our concern throughout is the people behind the legal language: those speaking publicly, seeking a secure future for their children, or facing restrictions because of their work—or their relationship to someone targeted. These developments are not all new this week, but each deserves attention now.
1. Hong Kong and Hong Kong people abroad
National security arrests over social media posts
The Hong Kong authorities announced that police arrested a 38-year-old man and a 38-year-old woman in Kowloon on 6 October on suspicion of committing an act with seditious intention under section 24 of the Safeguarding National Security Ordinance.
According to the government’s announcement, the man, a licensed insurance broker, allegedly operated social media pages containing posts that incited hatred against the constitutional order, while also using the pages to sell insurance. Police obtained search warrants, searched the suspects’ residences and seized evidence. The announcement stated that both would be released on bail pending investigation.
These are police allegations, not findings of guilt.
Wong On-yin’s trial begins
The trial of commentator Wong On-yin, also known as Wong Kok-on, began in the District Court on 9 October. He denies charges of prejudicing a national security investigation and knowingly publishing material with seditious intention.
Reporting on the opening of the trial describes the prosecution’s allegation that Wong disclosed details of a meeting with national security police after being told not to reveal its contents. The 72-year-old is representing himself. The case number is DCCC 303/2026.
The proceedings remain ongoing. The opening of a trial should not be described as a conviction.
Lam Cheuk-ting’s acquittal upheld
On 9 October, the Court of Appeal dismissed the prosecution’s appeal against the acquittal of Lam Cheuk-ting and two other defendants on a charge of perverting the course of justice.
The case concerned an encounter during the 6 July 2019 Tuen Mun protest. According to reporting on the appeal decision, the court found insufficient evidence that the photographs or videos at the centre of the allegation existed. It also noted that footage of the encounter did not establish dishonest intent.
A settlement change for BN(O) children in the UK
A change to the Hong Kong BN(O) settlement rules took effect on 8 October. The Home Office’s Statement of Changes, HC 584 removes the five-year qualifying residence requirement for applicants who are under 18 on the application date.
This is not automatic settlement. Other requirements continue to apply, including those concerning the child’s immigration permission and parents’ status. Families should check their circumstances against the applicable rules before submitting an application.
Sentinel Defenders’ Response
People should be able to discuss public affairs and criticise those in power without an unclear boundary between disagreement and criminal speech. The cases above concern different conduct and must be assessed separately, but both make close scrutiny of national security enforcement essential.
We are particularly concerned about access to legal assistance and whether individuals can understand the obligations imposed on them. A person’s rights should not depend on their ability to navigate complex proceedings alone.
The decision in Lam’s case is a reminder that the prosecution must prove its allegations. That safeguard matters in every case, regardless of a defendant’s politics.
For Hong Kong families rebuilding their lives abroad, secure immigration status is also a practical protection issue. The BN(O) change is welcome, but clear guidance and accessible advice remain important so that eligible families can benefit from it.
2. Taiwan: Alleged surveillance of Puma Shen and his family
Taiwanese prosecutors indicted four people on 7 October over the alleged surveillance of legislator Puma Shen and his family.
According to CNA’s report, two Hong Kong residents allegedly paid private investigator Cheng Yung-chin NT$360,000 to arrange the monitoring. Cheng allegedly subcontracted the work for NT$180,000, with employees carrying out the surveillance.
Prosecutors say the operation included a miniature camera concealed in a scooter outside Shen’s home and round-the-clock monitoring between 1 October and 8 November 2024. Footage was allegedly passed through Telegram to intermediaries and ultimately to a client in Hong Kong.
Hong Kong Free Press reported that the information collected concerned Shen, his wife and their daughter. Arrest warrants were issued for the two Hong Kong residents. Prosecutors sought an 18-month prison term for Cheng; the court has not thereby imposed that sentence.
Sentinel Defenders’ Response
A family should not become a target simply because one member takes part in public life. The alleged monitoring of a home and a child makes privacy and immediate safety central concerns.
Our support for those affected does not depend on endorsing a politician’s views. It rests on a simpler principle: public disagreement is no justification for unlawful surveillance.
The investigation should establish the full chain of responsibility—not only who operated a camera, but who commissioned the work, paid for it and received the information. That must be done through evidence and fair proceedings, without exposing the family to further unnecessary publicity.
3. China policy watch: Human rights commitments and exit restrictions
China published its National Human Rights Action Plan for 2026–2030 on 11 June. The official announcement describes an introduction and eight chapters covering a range of rights and protections, and presents the plan as building on the previous 2021–2025 programme.
One commitment is especially relevant to defenders and their families. As highlighted in Amnesty International’s assessment, the plan promises to prevent and rectify unlawful restrictions on the movement of relatives of people involved in criminal cases.
Yet new exit and entry regulations, adopted on 31 July and effective from 15 September, permit travel restrictions on broadly defined national security and national interest grounds. Amnesty warns that the rules risk further institutionalising restrictions on defenders and their families, including provisions allowing authorities in certain circumstances not to disclose the reasons for a restriction.
Sentinel Defenders’ Response
A human rights plan should be judged by what changes for the people whose rights are restricted.
The promise to prevent unlawful restrictions on relatives is welcome. It should now be reflected in practice: family members should not face travel bans because of their relationship to a lawyer, artist or activist.
We will be looking for clear reasons for restrictions, meaningful opportunities to challenge them and the removal of arbitrary measures—not simply further statements of commitment.
4. China case watch: Artist Gao Zhen
Artist Gao Zhen was sentenced to three years in prison on 25 August for “defaming national heroes and martyrs,” according to Reuters’ reporting. The case concerns artworks created between 2005 and 2009, before the relevant law and subsequent criminal provisions were introduced.
In an urgent action published on 2 October, Amnesty International called for his conviction to be overturned and for his immediate, unconditional release. It also raised concerns about his apparent poor health and reported that his wife and son remain under a de facto exit ban despite not being accused of any crime.
Sentinel Defenders’ Response
Artistic criticism should not lead to imprisonment. We support calls for Gao’s release and for an end to restrictions on his family.
His case also shows why support cannot stop at the prison gate. The effects of a prosecution can reach a partner’s freedom of movement and a child’s everyday life. Their circumstances deserve sustained attention in their own right, not merely as background to the artist’s case.
5. Information security: Careful documentation, not quick fixes
The cases in this issue show how sensitive information can arise in different settings: a police interview, footage of a family home, or an immigration application.
The reported use of Telegram in the Taiwan case concerns the transfer of surveillance material. It is not, by itself, evidence that the victims’ Telegram accounts were compromised or that unsolicited group invitations formed part of the operation.
Similarly, Wong’s ongoing trial concerns alleged disclosure and national security offences. It does not establish a universal rule about every police meeting or confidentiality document.
Sentinel Defenders’ Response
Useful security guidance should reduce risk without creating false reassurance.
For a person facing legal restrictions, the first question is what those restrictions actually mean. Choosing a different messaging app does not resolve that legal question.
For someone concerned about surveillance, the priority is a response suited to their circumstances—not a generic instruction to confront a suspected operative or inspect unfamiliar equipment.
For organisations, our practical emphasis is careful handling of information: collect only what is needed, limit unnecessary disclosure and consider the consequences for the people named in a report or document. Protection should guide how we gather and share information, not be an afterthought.
