The former South Korean president now faces a life sentence for rebellion and seven additional years for obstruction, document falsification and deploying security forces “like a private army.” For a nation that has navigated democracy’s fragility before, the verdict is both a rebuke and a reassurance.

SEOUL. Outside the Seoul High Court on Wednesday morning, hundreds of Yoon Suk Yeol’s supporters gathered, holding portraits of the man they still regard as their president. Inside, Judge Yoon Sung-sik of the Seoul High Court was reading a verdict that added seven years to the former president’s sentence, delivering a comprehensive rejection of a legal and political defence that had rested, above all, on the argument that a sitting president has the inherent authority to do what Yoon did.
The court did not agree.
Yoon Suk Yeol was sentenced on Wednesday to seven years in prison for obstruction of official duties, abuse of presidential authority and falsification of documents in connection with his brief and chaotic declaration of martial law in December 2024, an episode that triggered the most serious constitutional crisis in South Korea in decades. The sentence comes on top of a life sentence he received in February for rebellion charges stemming from the same events. His legal team, led by attorney Yoo Jeong-hwa, called the verdict “very disappointing” and confirmed they would appeal to the Supreme Court. Yoon has also appealed his life sentence. Both appeals now proceed through a judicial system whose independence Yoon, in his final days as president, sought to undermine.
The story of how the president of one of Asia’s most successful democracies came to be sentenced twice in the space of three months requires a brief reckoning with what actually happened in December 2024. On a Tuesday evening, with little warning and no consultation with the full cabinet, Yoon appeared on national television and declared martial law, citing what he described as “anti-state forces” acting in parliament. The declaration lasted approximately six hours before the National Assembly voted to lift it, an act that under the South Korean constitution nullified the order. Yoon rescinded it and initially appeared to cling to office. He was impeached by parliament, arrested in January 2025, and has been in custody ever since.
The February life sentence on rebellion charges was the first and most serious judicial response to what prosecutors characterised as an attempt to subvert constitutional order through force. Wednesday’s separate conviction addressed the procedural offences that surrounded the rebellion: Yoon’s decision to convene only a small number of cabinet members before declaring martial law rather than the legally mandated full cabinet meeting; his subsequent falsification of documents to conceal the incomplete meeting; and his deployment of military and security personnel to resist law enforcement attempts to arrest him following his impeachment. Judge Yoon Sung-sik said the former president had “betrayed his duty” to protect citizens’ freedoms and “deepened social unrest” through his actions. He also found Yoon guilty of instructing his presidential secretary to provide false information to foreign media about the conduct of lawmakers during the martial law period, a finding that addressed the international dimension of the crisis.
The lower court that heard the case in January had sentenced Yoon to five years and partially cleared him of the Cabinet meeting charges. Wednesday’s appeals court reversed those acquittals entirely, finding him guilty on all counts and increasing the sentence to seven years. In a detail that reflects the comprehensive nature of the reversal, the court found that Yoon had violated the rights not only of the two Cabinet members who were absent from the incomplete meeting, but of seven additional Cabinet members who were not notified at all.
The case is proceeding alongside a separate trial in which prosecutors last week requested a 30-year prison term for Yoon over allegations that he deliberately escalated tensions with North Korea in 2024 by ordering drone flights over Pyongyang, with the alleged purpose of creating conditions that would justify the martial law declaration he was already planning. The allegation, if proven, would represent a remarkable escalation in the charges: a sitting head of state not merely abusing constitutional authority domestically but manipulating inter-Korean relations for personal political survival.
For the day-to-day life of South Korean citizens, the most immediately relevant consequence of Wednesday’s ruling concerns Yoon’s wife, Kim Keon Hee, whose sentence was increased to four years by the same court on Tuesday on charges that included accepting luxury gifts from the Unification Church, which had sought political favours from Yoon’s administration, and involvement in a stock price manipulation scheme.
South Korea has been here before. The country has impeached and imprisoned presidents before: Park Geun-hye was sentenced to more than 20 years before a pardon in 2021, and Roh Moo-hyun faced impeachment before the Constitutional Court overturned it. Each crisis has tested the resilience of South Korean democratic institutions and, ultimately, those institutions have held. Wednesday’s verdict is another such test passed, though the scale of charges against Yoon, spanning rebellion, obstruction, document fraud, and potential deliberate provocation of a nuclear-armed neighbour, makes this episode singular even by South Korea’s turbulent recent history.
The verdict drew no comment from the Blue House, which now has a president focused on the country’s foreign relations amid an extraordinarily complex geopolitical environment. For the supporters who gathered outside the courthouse on Wednesday, the legal proceedings remain evidence of a political conspiracy rather than a judicial reckoning. For the judges who have now twice found Yoon guilty of the most serious offences in Korean law, the matter is rather simpler: a president tried to break South Korea, and South Korea’s courts declined to let him.
