What the arrest of Au Kam San means for Macau

Paulo Coutinho

The recent arrest of former legislator Au Kam San under Macau’s revised national security law (NSL) marks a turning point for the city.

For the first time since the law’s 2023 amendments, a resident has been detained on allegations of “colluding with foreign forces” and spreading seditious information. While authorities emphasize the need to safeguard national sovereignty, the confidential nature of the charges and Au’s long record of peaceful political engagement raise critical questions about civil liberties and the future of freedom of expression in the city.

Au, 68, is a veteran of Macau’s pro-democracy movement. A co-founder of the New Macau Association (ANM) and an elected lawmaker from 2001 to 2021, he consistently advocated for greater transparency and political reform, and openly organized Tiananmen Square vigils. In recent years, however, he has stepped back from formal politics – especially following the tightening of candidate eligibility rules in 2021.

Last Wednesday, the Judiciary Police arrested Au at his residence. Authorities alleged he had been in contact with unnamed foreign anti-China organizations since 2022, supplying them with “large amounts of false and seditious information” for use in public exhibitions and online campaigns. These actions, they claimed, “aimed at inciting hatred” toward the central government and interfering with Macau’s 2024 Chief Executive election.

On July 31, the pretrial judge (juíz de instrução) imposed pretrial detention – a measure that is recommended under the amended law – making the swift decision a procedural necessity rather than a discretionary move.

Nonetheless, the legal basis for the arrest has raised concerns. Authorities have yet to disclose the specific content of the allegedly seditious materials or identify the foreign organizations involved. If it goes to trial, some of those details will eventually emerge – but under the NSL, authorities may prevent the disclosure of materials considered damaging to national security.

Macau media reported on the extraordinary detention, showing some incredulity at the action, since Macau residents are generally considered to have been mostly quiet or moderate in their political criticism or activism.

The event reverberated worldwide – putting the MSAR back on the global media agenda, which has otherwise been indifferent to the casino enclave’s affairs in recent years.

Commentators noted that while the government has invoked national security as a rationale for the action, the profile of the accused – an aging, retired public figure with a legacy of peaceful activism – suggests a “relentless crush on dissent,” as News Australia observed.

“If sharp criticism disappears completely, gentle criticism will become harsh,” a participant of Ou-Mun Tin Toi’s radio talk show “Macau Talk” said on Thursday, commenting on Au’s arrest and his critical approach to public service.

Macau authorities maintain that the new law is essential to shield the region from external interference and potential unrest. In their view, pre-emptive enforcement is part of a broader strategy to ensure national integrity. Yet the expansion of state power must be balanced with safeguards for fundamental rights.

As the city approaches another election cycle, the arrest of Au Kam San is not just a legal case – it is a statement. It signals a narrowing of political tolerance and a recalibration of what is permissible in public discourse. In times of political consolidation, how a society treats its critics defines the strength of its legal and moral foundations.

Macau still has the opportunity to demonstrate that national security and civic freedom are not mutually exclusive. But that will depend on what happens next – not just in courtrooms, but in the public square.
