The Supervision Law of the People's Republic of China (中华人民共和国监察法) was adopted by the 13th National People's Congress on 20 March 2018, the same session that amended the PRC Constitution to insert a new Section 7 ("The Supervisory Commissions") into Chapter III on State Structure. The Law operationalises Articles 123–127 of the amended Constitution, which create the National Supervisory Commission (国家监察委员会, NSC) as a supreme state organ ranking alongside the State Council, the Supreme People's Court and the Supreme People's Procuratorate, all answerable to the National People's Congress. Its central purpose is to consolidate fragmented anti-corruption authority — previously split among the Party's Central Commission for Discipline Inspection (CCDI), the Ministry of Supervision and the procuratorate's anti-graft bureaus — into a single state apparatus that operates jointly with, and is physically merged with, the CCDI under the principle of "one institution, two nameplates" (一套人马，两块牌子).
The Law's defining feature is its expanded jurisdiction over all persons exercising public power (所有行使公权力的公职人员), not merely Communist Party members. This sweeps in civil servants, managers of state-owned enterprises, public-school and hospital administrators, and grassroots self-governance officials — closing the gap left by Party discipline, which reached only the roughly 90 million CPC members. The supervisory commissions wield three core functions under Article 11: supervision (监督), investigation (调查) and disposition (处置). Most controversial is the liúzhì (留置, "retention in custody") power under Articles 22–24, which replaced the extralegal Party measure shuanggui (双规); it permits detention of suspects for up to three months, extendable once, in designated facilities, with limited statutory provision for defence-counsel access. The vertical structure runs from the NSC down through provincial, municipal and county supervisory commissions, whose chairs are elected by people's congresses at the corresponding level.
In operation since 2018, the supervisory system has folded the CCDI's discipline-inspection campaigns into a state-law framework, and its first NSC director, Yang Xiaodu, was succeeded by Liu Jinguo in 2023. Subsequent legislation deepened the regime: the Law on Officials' Supervisors / Supervisors and Inspectors Law (监察官法) of 2021 professionalised supervisory personnel, and a 2024 amendment refined coordination with criminal procedure. Critics, including international legal scholars, note tension between liuzhi and the procedural protections of the Criminal Procedure Law, since detainees fall outside ordinary criminal-justice safeguards until the case is transferred to the procuratorate for prosecution.
For the exam, the Supervision Law is a high-value topic in China-focused governance and political-system papers and in comparative-government sections of UPSC and FSOT. Examiners typically test: (1) its constitutional basis in the 2018 amendment and the NSC's rank within the state hierarchy; (2) the fusion of Party (CCDI) and state organs as a case study of party-state integration under Xi Jinping; (3) the liuzhi–shuanggui transition as an illustration of "rule by law" versus "rule of law"; and (4) the broadened jurisdiction over non-Party public officials. A common question angle asks candidates to evaluate whether the Law strengthens institutional accountability or concentrates power, making it essential to cite the specific constitutional articles and the 20 March 2018 enactment date.
Example
In March 2018, China's 13th National People's Congress passed the Supervision Law and elected Yang Xiaodu as the first director of the newly created National Supervisory Commission, merging it with the Party's CCDI.
