A lawyer has issued a stern warning regarding ongoing legislative efforts to further restrict the investigative authority of South Korean prosecutors. The expert argues that the complete abolition of a prosecutor’s supplementary investigation rights would likely be ruled unconstitutional and warns against using such legal reforms as a political tool for partisan gain.
The debate centers on the scope of the “supplementary investigation right” (보완수사권), a mechanism that allows prosecutors to request or conduct additional investigative work when police-referred cases are deemed insufficient for indictment. This authority has been a central point of contention since the 2022 amendments to the Criminal Procedure Act and the Prosecutors’ Office Act, which significantly narrowed the investigative jurisdiction of the prosecution service. According to the Supreme Prosecutors’ Office of the Republic of Korea, the current legal framework limits direct investigations by prosecutors to specific categories of major crimes, such as those related to corruption, the economy, public officials, elections, defense projects, and major disasters.
Constitutional Concerns Over Investigative Authority
The critique highlights a growing concern among legal scholars and practitioners that removing the remaining safeguards for supplementary investigations could undermine the integrity of the judicial process. Critics of the proposed legislative changes argue that the prosecution must retain the ability to bridge gaps in evidence to ensure that cases are trial-ready. If the investigative chain is severed, legal experts contend that it could lead to a surge in dismissed cases or flawed indictments, effectively paralyzing the pursuit of justice in complex criminal matters.
Furthermore, the constitutional question remains a focal point of the legal discourse. The Constitutional Court of Korea has previously reviewed the constitutionality of the 2022 legislative reforms. In its March 2023 ruling, the Court acknowledged that while the legislature has the authority to adjust the scope of investigative powers, the complete removal of such powers could potentially infringe upon the constitutional duties of prosecutors to uphold the rule of law and protect citizens’ rights. Legal analysts suggest that any further reduction in these powers would likely face immediate constitutional challenges, as it may be viewed as an attempt to restrict the judiciary’s ability to function independently of political influence.
Political Strategy vs. Judicial Independence
The former judge emphasized that legislative reform should prioritize the efficiency and fairness of the justice system rather than serving as a tool for political maneuvering. The warning underscores the tension between the ruling and opposition parties regarding the “de-prosecution” agenda. As the National Assembly debates these potential amendments, the focus has shifted toward whether the changes are driven by an genuine intent to improve investigative efficiency or by a desire to insulate certain entities from prosecutorial oversight.
The National Assembly of the Republic of Korea remains the primary venue for these discussions. Legislators advocating for the reforms argue that the changes are necessary to prevent the abuse of power and to establish a more balanced investigative structure where the police take a lead role. Conversely, opponents argue that the police currently lack the specialized expertise required to handle high-level economic and structural crimes, making the prosecutor’s role in supplementary investigations indispensable for maintaining public order.
Impact on Future Criminal Proceedings
The implications of this legislative tug-of-war extend to the daily operations of law enforcement and the courts. If the supplementary investigation rights are fully abolished, the prosecution would lose its ability to verify the veracity of evidence provided by police agencies during the pre-indictment phase. This could lead to a scenario where prosecutors are forced to rely solely on the initial evidence provided, even if it is incomplete or legally insufficient, potentially leading to lower conviction rates in high-profile cases.
As of this reporting, no official date has been set for the final vote on the proposed bills concerning the total abolition of supplementary investigation rights. The legal community continues to monitor the situation, with many expecting that any legislative move to strip prosecutors of these powers will trigger a series of injunctions and constitutional petitions. For those following the progress of these reforms, the official records of the Supreme Court of Korea and parliamentary committee minutes serve as the most accurate sources for tracking the timeline of these developments.
