Safeguard Defenders' Comprehensive report and review of Liuzhi and the NSC (2019) is a submission to nine United Nations Special Procedures. It lays out in unprecedented detail how China's new National Supervision Commission (NSC) and liuzhi, its system for disappearing suspects for up to six months, are operating. It also identifies a number of new developments related to the NSC, and how the new National Security Law and Liuzhi are being used to undermine the existing rights and protections within China's judicial system.
