Like the court system, the Prosecutors Offices of R.O.C. are attached to the courts at corresponding levels. There is one Supreme Prosecutors Office, six High Prosecutors Offices, and twenty District Prosecutors Offices. Because of the unified prosecutorial system, the Prosecutor General of the Supreme Court directs and supervises the prosecutors of his office and of the prosecutors offices attached to the lower courts and branch courts. This direction and supervision is provided in the areas of criminal investigations, public prosecutions and indictments, private prosecutions, the execution of criminal judgments, and the performance of other functions as prescribed by laws.
