Record
Courts have suspended the criminal cases against Lee since he became president, relying on Article 84 of the Constitution, which bars criminal prosecution of a sitting president except for insurrection and foreign aggression. On 16 October 2026 the Seoul High Court's chief judge told a National Assembly audit that the remand trial on a Public Official Election Act charge was on hold on that basis. Lee has denied wrongdoing in the cases and said prosecutors "went too far" in indicting him over money sent to North Korea. Realmeter polling put his approval at 35.3% in late October 2026, while Gallup showed 40%, with housing, the economy and a September landmine explosion on the border cited as pressures.
Supporters credit him with ending prosecutors' dual investigative and charging power and with a stable trade settlement; critics, including the People Power Party, argue the reforms remove checks on the government and that his North Korea policy is too soft.
