South Korea's Former President Yoon Indicted for Abusing Power in Martial Law Justification

This indictment marks the first criminal case brought by South Korea's second special counsel team against former President Yoon Suk Yeol, led by Kwon Chang-young.
Shin Won-sik and Kim Tae-hyo are accused of carrying out Yoon's instructions to send justification messages to allies, with involvement by the National Security Office and the Foreign Ministry, and the National Intelligence Service aided the outreach.
The messages described martial law as a measure to defend liberal democracy and as a political demonstration carried out within constitutional boundaries.
Prosecutors say disseminating these messages constitutes participation in an insurrection, and they are seeking to consolidate the trials of Yoon with Shin and Kim.
Yoon Suk Yeol was impeached and removed from office last year, adding context to the broad legal reckoning over the December 2024 martial law episode.
South Korea's jailed former President Yoon Suk Yeol has been indicted for the eighth time, this time for ordering officials to send messages justifying his martial law declaration to key allies including the United States, Britain, Japan, and the European Union, according to Korea JoongAng Daily. The charges were brought by the country's second special counsel team, led by independent counsel Kwon Chang-young.
Former National Security Adviser Shin Won-sik and his deputy Kim Tae-hyo were also indicted alongside Yoon. Prosecutors say all three helped spread a distorted account of the December 2024 martial law episode to foreign governments, according to Korea Herald.
Right after Yoon declared martial law in December 2024, officials from the National Security Office and the Foreign Ministry sent messages to allied governments. The National Intelligence Service also helped carry out the outreach, according to SE Daily. The messages described martial law as a move to "defend liberal democracy" and called it a "political demonstration" within constitutional limits.
Prosecutors say Yoon personally directed these communications. Shin Won-sik and Kim Tae-hyo are accused of carrying out his instructions. The goal, prosecutors argue, was to shape how key foreign partners understood the crisis — and to make an unconstitutional power grab look legitimate.
The charges go beyond just sending misleading statements. Prosecutors say spreading those messages made Shin and Kim active participants in an insurrection — a serious crime in South Korea. They also argue that civilian agencies like the Foreign Ministry were pushed to act outside their legal duties, according to Korea JoongAng Daily.
The special counsel team is now pushing to consolidate Yoon's trial with those of Shin and Kim. No trial dates have been set yet for most of the charges Yoon faces, according to Korea Herald. The legal process is moving slowly even as the charges pile up.
Yoon declared martial law on December 3, 2024. It lasted only hours before the National Assembly voted to lift it. He was impeached shortly after and removed from office. He has been in jail since then, facing a growing list of criminal charges, according to teleSUR English.
Yoon has argued that his actions were meant to defend South Korea's democratic order. Critics say he did the opposite — threatening the constitution he swore to protect. This latest indictment is the first brought by the second special counsel team, signaling that the legal reckoning is far from over.
The indictments have deepened South Korea's political crisis. Yoon has now been indicted eight times across multiple investigations. Courts have not yet set trial dates for most of the cases. Legal experts say the sheer number of charges makes a quick resolution unlikely, according to Korea JoongAng Daily.
The second special counsel team, led by Kwon Chang-young, is now a central player in the proceedings. Its first indictment targets not just Yoon but two senior national security officials. The scope of the case suggests prosecutors are building toward a broad account of how the martial law plan was executed and then covered up.
