South Korea's National Assembly passed a criminal procedure law amendment that fully abolishes the supplementary investigation authority of prosecutors [1].
The reform represents a fundamental shift in the nation's legal landscape by removing investigative powers from prosecutors to transition into a "post-prosecutor" era [1]. This change aims to complete a long-term reform agenda driven by the Democratic Party to restructure the criminal justice system [1].
For approximately 70 years, the existing criminal justice system remained the standard for the country [1]. The new legislation seeks to end this era by separating the power to investigate from the power to prosecute, a move intended to create a more balanced distribution of legal authority [1].
As part of this restructuring, the government will create a new Serious Crime Investigation Agency [1]. This agency is designed to handle the complex cases previously managed by prosecutors, ensuring that criminal investigations continue without the conflict of interest inherent in a single agency handling both investigation and indictment [1].
According to the legislative timeline, the amendment passed the National Assembly in 2024 and was scheduled to take effect in October 2024 [1]. While the law has passed, the transition period has raised questions regarding potential implementation gaps as the new agency becomes operational [1].
The Democratic Party lawmakers who drove the reform said the move is necessary to ensure accountability and prevent the abuse of power within the prosecution service [1].
“The reform represents a fundamental shift in the nation's legal landscape.”
This legislative shift fundamentally alters the balance of power within South Korea's executive branch. By stripping prosecutors of their investigative authority, the state is moving toward a model of checks and balances that separates the discovery of evidence from the decision to charge. The success of this transition depends on the operational efficiency of the new Serious Crime Investigation Agency to prevent a vacuum in the prosecution of major crimes.
