Former Macau Legislator Sentenced to 12.5 Years for Casino License Information Leak

On November 6, 2026, Au Kam San, a 69-year-old former Macau legislator, was convicted and sentenced to 12 years and six months in prison following a closed-door trial in September. The case marks the first publicly known prosecution under Macau's national security law, which was significantly expanded in 2023. Au was charged with subversion, making contact with overseas organizations to endanger national security, and breaching official secrecy rules.

The core allegation centers on Au's alleged leak of confidential information regarding casino licensing discussions. While serving on the Legislative Assembly's Follow-up Committee for Land and Public Concessions Affairs in 2021, Au participated in secret talks surrounding the renewal of Macau's casino operating licenses. According to the court, he shared information from these meetings with groups outside the territory. Notably, authorities have not publicly identified the recipients or specified the exact material disclosed. Au received an additional nine-month sentence specifically for the confidentiality breach, though the more serious national security charges drove the total sentence.

The timing of this case is significant given Macau's major gambling industry restructuring. In 2022, the Macau government granted new 10-year concessions to all six existing casino operators, with licenses going into effect in January 2023. These deals involved companies linked to major global gaming groups including Las Vegas Sands, MGM Resorts, and Wynn Resorts. Au's alleged actions occurred during the sensitive pre-renewal period when such information would have carried substantial commercial and political weight.

Beyond the casino licensing charges, prosecutors pursued broader national security allegations. Between 2023 and 2024, authorities alleged that Au worked with unnamed overseas organizations to gather and circulate what they characterized as false or politically damaging information. The stated aim was to promote opposition to Beijing, influence foreign governments, and interfere in Macau's leadership election in 2024.

Au's prosecution has generated significant international concern. Human Rights Watch has raised serious questions about due process, arguing the case could deter peaceful criticism of the government. His wife, Virginia Cheang, has characterized the prosecution as politically motivated. The family previously raised concerns about limitations on communication and access to independent legal representation, though the court stated Au had legal counsel and the right to defend himself, with regular family visits permitted after the verdict.

The case reflects the broader securitization of Macau's political environment since 2023. Au served in the legislature for two decades from 2001 to 2021, and his background as a teacher and democracy activist following the 1989 Tiananmen Square crackdown appears relevant to the prosecution's framing. The Macau government has defended the ruling and reiterated its commitment to implementing national security legislation. This prosecution signals heightened enforcement risk around access to sensitive gaming industry information in one of the world's largest gambling markets, with implications for how stakeholders and operators navigate regulatory processes in the territory.
