Former President Yoon Suk-yeol will be summoned on June 6 [2] by a special investigation team to face charges of abusing his authority [1].

The summons marks a critical escalation in the legal proceedings surrounding the Dec. 3, 2022, emergency martial law declaration [4]. It represents the first time the former leader will be questioned as a suspect in this specific capacity regarding the communication of the decree to international allies.

The second comprehensive special investigation team is focusing on allegations that Yoon directed the spread of messages to justify the martial law decree [1]. Investigators believe Yoon attempted to use the National Security Office, the National Intelligence Service, and the Ministry of Foreign Affairs to convey these justifications to the U.S. and other allied nations [1].

"The second comprehensive special investigation team will summon former President Yoon Suk-yeol tomorrow (6th) on charges of directing the dissemination of messages justifying martial law," Kwon Chang-young said [1].

Beyond the abuse of power charges, the investigation is expanding into more severe allegations. The team has scheduled a separate investigation into rebellion charges for June 13 [3]. This suggests that prosecutors are looking beyond the administrative misuse of government offices and are examining the legality of the martial law declaration itself.

Another anchor for YTN News said the former president is being summoned as a suspect on charges of abuse of power [1].

The current investigation comes as the special probe reaches its 102nd day since its launch [1]. The proceedings are taking place at the special prosecutor's office in Seoul [1].

The second comprehensive special investigation team will summon former President Yoon Suk-yeol tomorrow (6th).

The transition from investigating administrative abuse to probing rebellion charges indicates a significant shift in the legal strategy against the former president. By examining whether the Dec. 3, 2022, decree was a legal act of state or a criminal attempt to seize power, the special investigation team is moving toward a potential indictment that could carry severe penalties and redefine the legal boundaries of presidential authority in South Korea.
