South Korea’s Supreme Court Confirms Prison Sentence for Ex-President Yoon Suk Yeol
In a landmark decision, South Korea’s Supreme Court has upheld a seven-year prison sentence for ex-President Yoon Suk Yeol. This marks the first case involving Yoon to reach the apex court, stemming from his controversial martial law declaration in 2024. For more details, see the original report.
The Supreme Court’s decision aligns with an earlier ruling by the Seoul High Court, which found Yoon guilty of several charges, including denying Cabinet members the right to discuss the martial law declaration, falsifying documents to hide this, and deploying security forces to resist arrest post-impeachment. Further information is available in the high court’s ruling.
Although martial law was quickly repealed by lawmakers, who managed to bypass a blockade of armed forces at the National Assembly, Yoon’s actions resulted in a significant political upheaval. Discover more about the incident here.
Yoon, who remains detained, was absent from the court proceedings. He faces multiple ongoing trials and has filed an appeal against a life sentence for rebellion, which is his most severe charge to date. Details on his life sentence appeal can be found here.
Reacting to the Supreme Court’s ruling, Yoon’s legal team expressed “deep regret,” suggesting the decision was made without adequate consideration.
The Constitutional Court had previously dismissed Yoon from office in April 2025, citing the martial law decree as lacking legal justification and procedural adherence. More on the Constitutional Court’s decision can be found here.
Key testimonies from former Cabinet members, including then-Prime Minister Han Duck-soo, indicate that Yoon did not seek their input before declaring martial law. Instead, they were informed of his decision unilaterally, with nine members not even summoned to the crucial meeting. More insights into Han Duck-soo’s testimony are available here.
The brief yet intense period of martial law caused considerable disruption in South Korea, halting political and diplomatic activities and unsettling financial markets. Stability returned following Lee Jae Myung’s victory in the expedited presidential election of June 2025. Learn more about the election here.
Yoon is also challenging a 30-year prison sentence related to accusations of escalating tensions with North Korea via drone activities in 2024, purportedly to justify martial law domestically. His legal representatives argue these actions were retaliatory measures against North Korean provocations involving balloon launches.
