Jurisdictional Gaps Persist Despite Launch of Corruption Investigation Office and Public Prosecution Service
Although the separation of investigation and prosecution powers has taken effect, the gap of jurisdictional conflict remains unchanged.
The overhaul of the criminal justice system, long a central goal, has begun with the launch of the Public Prosecution Service and the Office for Investigation of High-Ranking Officials, but follow-up legislation to fill the blind spots left in the system's design has emerged as a key task. According to Yonhap News, experts pointed to the possibility of jurisdictional conflicts, noting that the boundaries of authority between the new investigative bodies remain unclear under the law. The point is that establishing institutions alone will not make the problems disappear.
Why Follow-up Legislation Became an Issue
The core of this overhaul was dividing the investigative and prosecutorial powers that the prosecution service had monopolized. Under the new structure, the Office for Investigation of High-Ranking Officials handles investigations, while the Public Prosecution Service handles indictments. However, unless rules are put in place determining which body investigates first and to what extent a case must be handed over when both are involved in the same matter, coordination on the ground is bound to be prolonged.
This is precisely where experts' concerns lie. If disagreements arise over which agency should lead an investigation in a case with ambiguous jurisdictional boundaries, delays are likely to follow. In particular, for serious crimes, where the speed of the initial investigation can determine success or failure, analysts say the time spent on consultation itself can result in real losses.
Key Issues: Jurisdictional Conflicts and Coordination Mechanisms
The tasks for follow-up legislation can be summed up in two main areas. First, the jurisdictional criteria for the two investigative bodies must be codified into law. Without detailed standards determining which agency is responsible based on the type and scale of a case, disputes over borderline cases are bound to recur.
The second is a mechanism to resolve conflicts when they actually occur. Options under discussion include having a third-party body mediate or establishing procedures requiring a resolution within a set deadline once a dispute arises. Critics warn that if the matter is left solely to voluntary consultation between agencies without a coordination channel, unresolved cases risk drifting indefinitely. Both ruling and opposition parties broadly agree with the purpose of the reform, and there is a prevailing view that supplementary legislation is needed to ensure its effectiveness.
The opposition also argues that the reform could create a vacuum in investigative authority. Jeong Jeom-sik, floor leader of the People Power Party, said, "Abolishing the prosecution means the death of the criminal investigation system," and announced he would push to introduce a bill first to restore supplementary investigations. Meanwhile, the reform's architects maintain that dispersing authority is a normalization measure to prevent investigative overconcentration. There is also strong expert opinion that criminal justice reform should be evaluated from the standpoint of establishing fair investigative procedures and protecting human rights.
Impact on Markets and Investigative Practice
Unclear jurisdiction could become an even greater variable in corporate investigations. Large-scale economic crimes, by their nature, tend to fall within the overlapping jurisdiction of both bodies. Analysts say that if delays occur because the investigating authority is undetermined, it could affect the company's management decisions and market confidence.
Practical confusion arising during the institutional transition, such as the status of seconded prosecutors, is another area that must be smoothed out through legislation. In fact, when the issue of seconded prosecutors still belonging to the existing prosecution service surfaced on the first day of the Public Prosecution Service's launch, the team of special prosecutor Kwon Chang-young (2nd special investigation team) took the position that the existing secondments remain valid. Analysts say that to reduce transition-period confusion, such transitional measures should also be clearly codified into law.
Legislative Timeline and Outlook
Follow-up legislation is expected to be discussed mainly in the National Assembly's Legislation and Judiciary Committee. Once amendment bills codifying jurisdictional standards and establishing coordination mechanisms are submitted, disputes over the scope of investigative authority are likely to resurface during negotiations between the ruling and opposition parties.
A realistic outlook is a two-track approach: laying out the basic framework within the regular National Assembly session at the earliest, then refining detailed operational rules based on cases arising after implementation. Whether a coordination mechanism can be put in place before jurisdictional conflicts surface in actual cases will be the yardstick for measuring the reform's effectiveness.
