Former South Korean President Yoon Suk-yeol was summoned for a second time on Saturday to be questioned as a suspect on rebellion charges [1].

The investigation focuses on the legality of the Dec. 3 emergency martial law and whether the former leader orchestrated an uprising by deploying armed military personnel to the National Assembly [1, 2].

Yoon arrived at the second comprehensive special prosecution office in Seoul for the session [1, 3]. This appearance follows a previous summons just one week ago [1, 4].

Investigators are examining whether Yoon directed the deployment of soldiers carrying weapons to the legislature to incite a riot [2]. The questioning lasted between eight hours and 45 minutes and approximately nine hours, beginning at 10 a.m. and concluding at 6:45 p.m. [3, 5].

Legal representatives for the former president have challenged the basis of the investigation. Song Jin-ho, a lawyer representing Yoon, said that rebellion charges cannot be applied to the commander-in-chief of the armed forces [2].

The special prosecution team is currently working to resolve remaining suspicions regarding the military's role during the martial law period [1, 2].

The investigation focuses on whether the former leader orchestrated an uprising by deploying armed military personnel to the National Assembly.

The repeated summoning of a former head of state as a criminal suspect underscores the severity of the legal challenges surrounding the Dec. 3 emergency martial law. By focusing on the specific act of deploying armed troops to the legislature, the special prosecution is attempting to build a case for 'rebellion'—a charge that carries significant legal weight and could set a precedent for executive accountability in South Korea.
