Shuanggui (双规, "double designation") was the signature coercive instrument of the Chinese Communist Party's discipline inspection system, operated by the Central Commission for Discipline Inspection (CCDI) and its local branches. The name derives from a 1994 provision and Article 28 of the CCP's 1997 Regulations on Disciplinary Inspection, which empowered investigators to require a Party member under suspicion to explain matters "at a designated time and a designated place" (在规定的时间、规定的地点). Because it operated entirely within Party rules rather than the state's Criminal Procedure Law, shuanggui detention had no statutory time limit, no right to counsel, and no judicial oversight; it was a Party-disciplinary measure that nonetheless functioned as de facto criminal detention. A parallel measure, shuangzhi (双指), applied to non-Party state functionaries under administrative supervision rules.
In practice, a target was summoned and held incommunicado in a sequestered location — often a guesthouse, hotel, or sanatorium — under round-the-clock guard while investigators extracted confessions of graft. The procedure preceded and supplied evidence for formal prosecution: once shuanggui established a Party verdict, the subject was typically expelled from the Party (开除党籍) and handed to the procuratorate for criminal trial, the so-called "double expulsion" (双开). Critics, including the Supreme People's Procuratorate's own commentators and international bodies, condemned shuanggui for routine sleep deprivation, forced confessions, and several deaths in custody; the 2013 death of Wenzhou official Yu Qiyi during interrogation became a notorious example. The system embodied the Party-over-state principle, placing senior cadres beyond ordinary police and courts.
Shuanggui was formally abolished and absorbed by the establishment of the National Supervisory Commission (NSC, 国家监察委员会) under the 2018 Supervision Law (监察法), enacted by the National People's Congress in March 2018 alongside a constitutional amendment adding Articles 123–127 creating supervisory commissions as a new branch of state power. Shuanggui was replaced by liuzhi (留置, "retention in custody"), a statutory measure under Articles 22–24 of the Supervision Law that imposes a maximum detention of three months, extendable once by three months, and extends coverage to all public officials, not merely Party members. While liuzhi gave the practice a legal basis, it retained the denial of defence counsel during the detention phase, drawing continued criticism. As of 2026 shuanggui no longer formally exists, but liuzhi is widely regarded as its institutional successor within Xi Jinping's anti-corruption campaign run by the merged CCDI–NSC.
For the exam, shuanggui is most relevant to the China political system and governance papers (and FSOT/UPSC China-studies sections), where the typical question angle is the Party–state distinction and the rule-by-law versus rule-of-law debate. Candidates should be able to contrast shuanggui (Party rule, no time limit) with liuzhi (statutory, six-month cap, all officials), cite the 2018 Supervision Law and the constitutional supervisory-commission amendment, and explain how the discipline apparatus illustrates the supremacy of the CCP over China's judiciary.
Example
In 2015, the CCDI placed former security tsar Zhou Yongkang's associates under shuanggui to build the corruption case that led to his life sentence, a hallmark prosecution of Xi Jinping's anti-graft campaign.
Frequently asked questions
The 2018 Supervision Law abolished shuanggui and introduced liuzhi (retention in custody) under the new National Supervisory Commission. Liuzhi has a statutory three-month limit, extendable once to six months, and applies to all public officials rather than only Party members.
