South Korean President Lee Jae-myung Overhauls Criminal Justice System
By Drooid · · How we work
Core Event
President Lee Jae-myung signed a revised Criminal Procedure Act that transferred primary investigative authority from prosecutors to the police. The law, which took effect on a Friday, retains prosecutors’ role in deciding whether cases proceed to trial and creates two new agencies: a Prosecution Service for indictment decisions and a Serious Crimes Investigation Agency for probes into corruption and national-security offenses. The reform also abolishes the Supreme Prosecutors Office.
Background & Context
South Korea’s prosecutorial office has long been a powerful political actor; four of the eight presidents elected since 1987 were later imprisoned or ousted after investigations, and former President Roh Moo-hyun died by suicide while under probe. Lee, who assumed office after a “martial-law fiasco” involving his predecessor Yoon Suk-yeol, faced multiple criminal cases before his inauguration, including allegations of aiding land developers, misusing public funds and violating election law. He has described the prosecutions as politically motivated.

Why It Matters / Impact
Proponents argue the changes will curb “politically motivated investigations” and reduce prosecutors’ historic dominance, which has contributed to political instability. Critics warn that moving investigations to the police could create gaps in victim protection, especially for women and low-income individuals who may lack access to legal assistance. The shift also raises concerns about increased political control over the police, an agency traditionally more directly manageable by the executive.
