President Lee Jae-myung holds office with constitutional immunity that suspends ongoing trials related to pre-presidency indictments on election law, land development, and public funds matters. Recent justice system reforms, effective in early October 2026, have transferred investigative authority from prosecutors to police and new agencies, limiting the institutions previously involved in his cases. Acting Justice Ministry officials have confirmed no directive to dismiss charges, while a review committee examines past prosecutorial conduct without predetermined outcomes. These structural protections, combined with the short timeline to 2027, underpin trader consensus against arrest. Shifts could arise from unexpected loss of legislative support, successful legal challenges to immunity, or major new evidence emerging outside reformed channels.
