South Korea's Judicial Reform Takes Effect as Chief Justice Faces Complaint, Retrial Petition
South Korea’s judicial reform package, known as the Judicial Reform 3 Laws, entered into force on December 12 with two high-profile developments that drew international attention. On the same day, Chief Justice Jo Hoi-dae was reportedly named as a defendant in a criminal complaint alleging “law distortion crime,” filed with the National Police Agency’s top investigative unit. The complaint was submitted by attorney Lee Byung-cheol and targets Jo Hoi-dae and another Supreme Court justice in connection with a May last year ruling that remanded a presidential election-law case involving Lee Jae-myung, the former presidential candidate.
The complaint claims the Supreme Court justices distorted the Criminal Procedure Act by allegedly not applying the principle of written submissions in that decision. The prosecution or police have not disclosed any charges yet, and the case was assigned to the Yongin Western Police Station. Officials said the investigation could be reevaluated or reallocated as needed given the alleged seriousness of the matter.
The second element tied to the reform day concerns the first petition under the newly enabled “retrial petition” mechanism, filed with the Constitutional Court of Korea. A Syrian national known as Mohammad, who had lived in Korea for 11 years before being deported, petitioned the Constitutional Court to review the Supreme Court’s dismissal of his appeal.
Mohammad’s lawyers argue that the Supreme Court’s ruling violated fundamental rights, including the right to pursue happiness, bodily freedom, freedom of residence and movement, and family life. They also contend that deportation to a third country, the use of a Korean-language-only judgment, and the sequence of deportation during proceedings undermine the right to a fair trial. The petition was reportedly submitted within 10 minutes of the Supreme Court’s decision.
Legal analysts, however, have suggested that Mohammad’s petition is likely to be dismissed because it may fail to meet the statutory 30-day deadline for filing such challenges. If this initial petition is dismissed, the lawyers indicated they would refile.
Several observers see these events as a test case for Korea’s three reforms: the so-called crime of distorting the law, a formal channel to challenge final Supreme Court rulings via the Constitutional Court, and an increase in the number of Supreme Court justices. The reforms aim to increase accountability, streamline judicial review, and potentially adjust the balance of Korea’s highest courts.
For U.S. readers, the developments matter because Korea is a major player in global supply chains, technology, and semiconductor manufacturing. Changes to how final court decisions can be challenged, and how judicial oversight is exercised, can influence risk assessments for foreign investment, intellectual property disputes, and cross-border contracting. Korea’s move to broaden judicial review and tighten scrutiny of high court decisions may affect how international companies plan and resolve disputes, while its handling of asylum and deportation cases touches on human-rights considerations that intersect with U.S. policy and refugee cooperation.
In Seoul, the Supreme Court remains the final appellate body for most civil and criminal matters, while the Constitutional Court handles constitutional challenges. The National Police Agency coordinates criminal investigations, and local police stations such as Yongin Western Police Station conduct day-to-day inquiries. The two cases announced on the reform day thus highlight a dynamic moment for Korea’s judiciary and its interface with international observers.
