Despite various efforts to eradicate school violence, it continues to persistently increase. This study focuses on the growing trend of offending students resorting to administrative lawsuits by challenging the decisions of the School Violence Countermeasures Deliberation Committee following incidents of school violence. From the year 2020, after the revision of the School Violence Prevention Act, up to the present, judgments on administrative lawsuits pertaining to contested school violence decisions were collected, and a total of six cases were selected. The study offers a detailed analysis of the contentious issues, legal basis for decisions, and the court’s rulings on the presence of school violence as indicated in the judgments. Based on this, the following suggestions are proposed. Firstly, in the process of handling school violence incidents, it is suggested that the concept and scope of school violence should be clearly defined, avoiding broad interpretations. The focus should be on the objectives of the “School Violence Prevention Act,” which emphasize the protection of the human rights of both the offending and victimized students, as well as their cultivation as responsible members of society. Secondly, when dealing with school violence incidents, the diverse contexts of both the offending and victimized students should be taken into consideration for appropriate measures. Lastly, in order to prevent and eliminate school violence, it is highlighted that not only guardians but also various stakeholders such as schools and school community members play a crucial role and need to make efforts.
