Seoul, South Korea witnessed a landmark judicial moment on February 19, 2026, as former President Yoon Suk Yeol received a life sentence. A court found him guilty of leading an insurrection following his short-lived martial law declaration in December 2024. This dramatic verdict closes a tumultuous chapter in South Korean politics, underscoring the nation’s unwavering commitment to its hard-won democracy. The events plunged the country into constitutional crisis, threatening to unravel decades of democratic progress, yet ultimately showcasing the resilience of its institutions and people.
A Nation’s Reckoning: The Verdict Against Yoon Suk Yeol
Presiding Judge Ji Gwi-yeon of the Seoul Central District Court delivered the historic ruling, convicting Yoon Suk Yeol of orchestrating a rebellion. The court determined Yoon’s intent was to paralyze the National Assembly and seize unchecked power. While prosecutors had sought the death penalty—a largely symbolic move as South Korea maintains a de facto moratorium on executions—the court ultimately imposed life imprisonment. This judgment represents the first time in three decades a South Korean leader has been sentenced for insurrection, drawing stark parallels to past military strongmen.
The verdict was met with a mix of reactions. Supporters outside the courthouse, watching the proceedings on a big screen, expressed despair and anger, shouting “political judge, step down.” Conversely, progressive groups celebrated the outcome, though some voiced disappointment that the death penalty wasn’t imposed. The ruling sends a powerful message about accountability, even for former heads of state, in a nation where presidents frequently face legal scrutiny after leaving office.
The Fateful Night: December 3, 2024
The crisis began on December 3, 2024, when then-President Yoon Suk Yeol, 65, declared martial law in a late-night televised address. He controversially claimed “anti-state forces” within opposition parties were sympathetic to North Korea. Within hours, armed soldiers, transported by helicopter, descended on the National Assembly. Their objective: to storm the chamber where lawmakers were gathered.
However, the attempted seizure was met with immediate, fierce resistance. Shocked citizens, along with lawmakers and parliament staff, rushed to barricade entrances. They used furniture and their own bodies to block soldiers from reaching the legislative floor. These chaotic scenes, broadcast live across the nation, revived dark memories of South Korea’s authoritarian past. The declaration struck at the heart of the nation’s democracy, sparking widespread condemnation. In a remarkable display of institutional strength, lawmakers forced their way into parliament and voted unanimously to block the decree. Yoon reversed course within six hours, averting a full-blown military takeover.
Resilient Democracy: How South Korea Fought Back
The swift and decisive response to Yoon’s martial law declaration stands as a testament to the robustness of South Korea’s democratic system. Despite the initial shock, parliamentarians and ordinary citizens acted with remarkable speed and unity. Their collective efforts ensured the martial law was lifted before it could fully take root. Frank Jannuzi, President and CEO of the Maureen and Mike Mansfield Foundation, characterized these events as “the most remarkable story,” highlighting the enduring resilience of South Korean democracy.
Current President Lee Jae Myung, Yoon’s political rival, deliberately avoided politicizing the trial. This measured approach helped to “cool down the temperature” of the charged political atmosphere, according to Jannuzi. It also allowed President Lee to focus on critical foreign policy objectives, such as strengthening regional alliances. The nation’s ability to navigate such a profound constitutional crisis, culminating in the legal prosecution of a former president, demonstrates a delicate yet firm adherence to the rule of law.
Unpacking the Insurrection Charges
The Seoul Central District Court meticulously outlined its findings that led to the insurrection conviction. Judge Ji Gwi-yeon stated it was clear Yoon’s intention in declaring martial law was to paralyze the National Assembly for a significant period. This was evidenced by the wording of the military decree and attempts to arrest political opponents, including the leader of the opposition Democratic Party and his own ruling party’s leader, Han Dong-hoon. The very act of dispatching armed soldiers to the parliament building by helicopter was deemed a clear act of insurrection.
Yoon, a former prosecutor, consistently denied the charge, labeling it “a delusion and a work of fiction.” He argued his martial law imposition was meant to alert the public to political gridlock caused by the opposition’s legislative majority. Yoon claimed he was exercising his constitutional authority and had no real intent to arrest lawmakers or deploy heavy weaponry. However, prosecutors countered that his actions clearly aimed to disable the legislature and prevent lawmakers from overturning the decree, thus exceeding his constitutional authority. They further noted Yoon’s lack of remorse and the continued risk of similar actions.
Wider Implications and Co-Defendants
The legal fallout from the martial law attempt extends beyond Yoon Suk Yeol. Several key allies and former officials have also faced severe consequences for their roles. Former Defense Minister Kim Yong-hyun was found guilty of playing a major role in the insurrection, receiving a 30-year prison sentence. Kim had previously taken responsibility for ordering soldiers to enact martial law. Four other former military and police officials received sentences ranging from 3 to 18 years.
Other high-profile convictions include former Prime Minister Han Duck-soo, who was sentenced to 23 years in prison. He was convicted for attempting to legitimize the decree and falsifying records. Former Interior Minister Lee Sang-min received seven years for participating in the rebellion, including relaying orders to cut power and water to media outlets. These preceding sentences established a strong legal precedent for the gravity of the martial law attempt. Yoon’s legal troubles are also ongoing; he faces multiple charges related to his martial law declaration and other actions during his presidency. He was previously sentenced to five years for obstructing authorities and fabricating documents. His wife, Kim Keon Hee, is also serving a sentence for an unrelated bribery charge.
A History of Turmoil: Presidential Trials
Yoon’s life sentence marks a significant moment in South Korea’s democratic narrative. The country has a complex history of presidents facing impeachment, criminal investigations, and prosecution after leaving office. The most direct historical parallel is former President Chun Doo-hwan, an army major general, convicted in 1996. Chun was found guilty of seizing power in a 1979 military coup and presiding over the bloody 1980 Gwangju massacre. Initially sentenced to death, his penalty was commuted to life imprisonment and he was later pardoned.
The fact that Yoon was the first president in South Korean history to be arrested while in office highlights the nation’s evolving commitment to accountability. While presidents enjoy immunity from many charges while in power, insurrection is one of the few criminal charges from which they do not. This verdict reaffirms that even the highest office does not place an individual above the law, a crucial pillar for any functioning democracy.
