In specific cases, the South Korean prosecutor has absolute dominance, especially in major cases, and the police can only help the prosecutor, but not handle the case independently. All cases must go through the prosecutor, who decides what evidence to take and how to obtain it, then directs the police work, and finally the prosecutor appears in court to accuse.
According to the provisions of the Criminal Procedure Law of Korea, the prosecutor's investigation power covers all investigation fields. Therefore, Koreans call prosecutors "the king of criminal investigation".

The only way to become a South Korean prosecutor is to take the exam, which is very strict and has a high elimination rate. In 2002, the prosecutor brought down the South Korean president through the bribery scandal, which also brought great reputation to the South Korean prosecutors. Some Korean netizens even set up a website to praise the impartial prosecutor.
The Law on Public Prosecutor's Office gives public prosecutors the following powers: investigating crimes, initiating public prosecution and maintaining the necessary matters of public prosecution; Command and supervise the judicial police in criminal investigation; Make a request to the court for the correct application of laws and regulations; Command and supervise the execution of the referee; To execute civil litigation and litigation in which the state is a party or participant, and to direct and supervise the execution; Other matters prescribed by law.
In addition to investigating criminal cases, prosecutors are also responsible for achieving social justice in this field, which is also one of their main tasks. The procuratorate is responsible for the corresponding cases according to the division of labor, and exercises centralized control with the commanding police organs and relevant administrative organs.
