President Yoon Suk-yeol, indicted on charges of leading a rebellion, faces his first criminal trial on the 20th. President Yoon is expected to argue that the emergency martial law was justified and assert that the matter cannot be subject to judicial review. In contrast, the prosecution will argue that the emergency martial law was illegal with the purpose of disrupting the constitutional order. During this trial, a decision on whether to release President Yoon from detention is also expected. President Yoon may appear in court directly to argue the illegality of his detention.
