A South Korean court has sentenced former President Yoon Suk Yeol to life imprisonment for masterminding an insurrection linked to his December 2024 attempt to impose martial law, in a verdict widely seen as the most consequential of a series of trials against the ousted leader.
As reported by Reuters, prosecutors had initially sought the death penalty, citing Yoon’s attempt to deploy troops to parliament in an effort to paralyze its functions. The insurrection lasted only six hours but triggered a major political crisis, testing South Korea’s democratic resilience.
Court Findings and Sentencing
Judge Jee Kui-youn, speaking for a panel of three judges at the Seoul Central District Court, stated that Yoon conspired with his former defense minister, Kim Yong-hyun, and other officials to subvert the constitutional order by using armed forces and equipment to attempt arrests in parliament. The actions, the court ruled, caused significant social disruption.
Yoon, 65, appeared ashen-faced in court. Kim Yong-hyun received a 30-year sentence, while several other top officials were also sentenced. The court emphasized that under South Korean law, masterminding an insurrection carries a maximum sentence of either death or life imprisonment. South Korea has not executed anyone since 1997.
Yoon’s Response and Legal Options
Yoon denied wrongdoing, claiming his actions were within presidential authority and aimed at highlighting obstruction by opposition parties. His legal team said they may appeal, arguing the ruling ignored evidence-based legal principles. Similarly, Kim and other defendants are expected to file appeals. Yoon is likely to remain detained at the Seoul Detention Centre during the appeals process.
This ruling comes as part of the eight trial proceedings Yoon faces. In a separate trial, he is appealing a five-year sentence related to obstructing authorities after the martial law declaration. Judicial guidelines call for the first trial to conclude within six months and the full process, including appeals, within two years, though proceedings often extend beyond these timelines.
Public Reaction and Political Implications
Yoon’s martial law attempt, though brief, sparked mass protests and strong public resistance. Hundreds of supporters rallied outside the court, calling for his release, while President Lee Jae Myung praised citizens for opposing martial law peacefully. Observers note the ruling reinforces South Korea’s commitment to constitutional order and democratic principles.
Ko Jeong-suk, a Seoul resident, expressed support for the life sentence, saying it serves as a warning against future attempts to subvert democracy. The case has sent shockwaves across Asia and raised global attention due to South Korea’s role as a major U.S. ally and key democratic nation.
The court’s verdict marks a historic moment in South Korean politics, underscoring the risks of executive overreach and the strength of civil society in upholding democracy.
