Sawt Falasteen - Macau to hold closed-door trial in first national security case

The Chinese casino hub expanded the scope of national security laws in May 2023, and a new bill passed earlier this year allows judges to hear national security cases behind closed doors.

Lawyers and rights groups have warned that the rule could undermine the functioning of government departments and apply to "any judicial case".

Former Macau lawmaker Au Kam San in July 2025 became the first person to be arrested under the expanded law, with authorities alleging he had ties to foreign groups endangering China.

The judge decided to "hold the trial behind closed doors in order to ensure that national security interests are not compromised", a statement released by Macau's final appeals court said.

After Au's arrest, details about the case remained scarce until this July, when judicial authorities in Macau confirmed that he would stand trial as a "principal offender" of subversion and other crimes.

The court said the trial decision had been confirmed by Macau's national security committee, following a request from the city's public prosecutions office.

The proceedings are set to begin September 16.

Au, 69, is a primary school teacher who became one of Macau's longest-serving pro-democracy legislators before deciding not to seek re-election in 2021.

Authorities said that a court-appointed lawyer previously accepted by Au will continue to represent him.

Michael Polak, a London-based barrister representing Au, said earlier this year that authorities having "appointed a state lawyer does not remedy the fundamental deficiencies in these proceedings which have all the appearances of a show trial".

"He is a Portuguese national and has been kept incommunicado for one year without access to his family or an independent lawyer," Polak added.

Au's daughter Cherry said the family is not allowed to visit or communicate with him.

"All we ask for is a fair trial, due process, and for his more than three decades of dedication to the people of Macau not to be erased or forgotten," she said in a statement in July.

Under Macau's security law, subversion offences are subject to a prison term of up to 25 years.
