Macao Lawmakers Approve Closed-Door Trials for National Security Cases

On March 19, 2026, Macao's Legislative Assembly unanimously approved a bill allowing closed-door trials in cases deemed to affect national security. Under the new legislation, if both judges and the city's national security committee agree that public hearings could endanger national security, legal proceedings can take place privately.

Expanded Authority of the National Security Committee

The law grants expanded authority to the national security committee, which includes security officials, the city's leader, and now also comprises heads of cultural, educational, and youth-related departments. This committee has the ultimate authority to decide whether a case pertains to national security and can order that hearings be held behind closed doors. Its decisions are final and not subject to appeal or judicial review.

Implications for Transparency and Political Expression

This move has raised concerns among observers due to implications for transparency and political expression. The concern is especially pronounced following the 2023 detention of a former pro-democracy lawmaker under Macao's national security law. Critics argue that the legislation could be used to suppress dissent and limit public scrutiny of sensitive cases.

Government's Justification

The government maintains that the legislation is crucial for protecting China's sovereignty and development interests. They argue that the ability to hold closed-door trials in national security cases is necessary to prevent potential threats and ensure the stability of the region.

The law took effect one day after its publication in the official gazette, marking a significant shift in Macao's legal landscape concerning national security and judicial transparency.
