The purpose of this study is to propose revisions to the Jeju 4.3 Special Law for the purpose of further investigation of Jeju 4.3 so that the complete resolution and appropriate legal solutions may come. The President, Moon Jae-In, who visited Jeju on April 3, 2018, promised a complete resolution of the Jeju 4.3 incident, defining the Jeju 4.3 incident as "violence perpetrated by state power." On Jan. 17, 2019, the Jeju District Court ruled in a retrial suit filed against the military tribunal by 18 surviving inmates under the leadership of the Jeju 4.3 Truth Commission and the Citizens' Solidarity for the Restoration of Honor. This is a very important case in which the military tribunal and their rulings were ruled invalid. Jeju 4.3 is still a painful history of Jeju that has not been resolved.
