directly transferred to the new National Supervisory Commission. The Procuratorate's anti-corruption personnel saw a similar transition. Powers and jurisdiction The Supreme People's Procuratorate serves as the highest prosecutorial power in the People's Republic of China, overseeing the nation's local and special procuratorates. As determined by the Organic Law, the primary function of the Procuratorate is to suppress illegal activities, particularly those which undermine the interests of China's ruling party, the Chinese Communist Party. The jurisdiction of the Procuratorate encompasses all cases related to criminal law, public and state security, people's courts, prisons, detention centers and labour institutions within the People's Republic of China. The agency does not oversee the prosecution of cases from the special administrative regions of Hong Kong or Macau, except those that are investigated by the Office for Safeguarding National Security of the CPG in the HKSAR. As specified in the Constitution of the People's Republic of China, the Supreme People's Procuratorate nominally exerts its powers independently, without interference from "any administrative organ, social organization or individual." However, like the Supreme People's Court, the Supreme People's Procuratorate must report to the National People's Congress, the highest state body in China. Prosecution and litigation The Supreme People's Procuratorate acts as a public prosecutor by handling both the investigation and prosecution of criminal cases in court, thus functioning as a civil law inquisitorial system. Such systems are also seen in Japan and socialist legal systems. Within the Procuratorate, criminal prosecution is overseen by four specialized departments that oversee “regular crimes, serious crimes, duty crimes, and new-type crimes," respectively. The agency reviews and arbitrates on which criminal suspects should be investigated and which criminal cases should be taken to a public prosecution. It may also initiate public interest litigation. Legal supervision The Supreme People's Procuratorate conducts reviews of rulings and investigations performed by local and special procuratorates. Additionally, for all types of cases, the Procuratorate may protest any rulings of the lower people's courts that it deems inappropriate or flawed by lodging a formal appeal with the Supreme People's Court. For civil and administrative cases, including intellectual property cases, this intervention mainly occurs after the court has handed down a legally binding and enforceable decision. The Procuratorate may act in this manner by choice or when petitioned by a litigant involved in a given case. Judicial interpretations The Procuratorate, either independently or in conjunction with the Supreme People's Court, may
