South Korea's Former President Yoon Suk Yeol Sentenced to Life for Insurrection
Former President Yoon Suk Yeol has been sentenced to life imprisonment with labor for leading an insurrection, while his wife's prison term was increased to four years on appeal.
Yoon Suk Yeol's Sentencing for Insurrection
Verdict and Sentence
The Seoul Central District Court found former President Yoon Suk Yeol guilty of leading an insurrection. Judge Jee Kui-youn sentenced him to life imprisonment with labor, the maximum custodial sentence for the charge.
Under South Korean law, leading an insurrection is punishable by death, life imprisonment with labor, or life imprisonment without labor. The court noted mitigating factors, including that Yoon's planning did not appear meticulous, he reportedly attempted to limit force, most of his plans did not succeed, he had no prior criminal record, he had served extensively in public office, and he was 65 years old.
Prosecution's Request
Independent counsel Cho Eun-suk's team had formally requested the death penalty, arguing that Yoon's actions constituted "a grave destruction of constitutional order" by mobilizing troops and attempting to arrest political opponents.
Prosecutors stated that Yoon's "unconstitutional and illegal emergency martial law undermined the National Assembly and the Election Commission, thereby destroying the liberal democratic constitutional order." They noted that Yoon had not expressed sincere regret or apologized to the public.
Court's Findings
The court determined that Yoon illegally mobilized military and police forces in an attempt to seize the National Assembly, arrest politicians, and establish unchecked power for a substantial period. Judge Jee said the court found the intention was to paralyze the assembly for a considerable period. The court also stated that the declaration of martial law resulted in significant social costs and that Yoon showed no remorse.
Yoon's Defense
Yoon maintained his innocence throughout the trial, describing the investigation as a "political conspiracy." He claimed he declared martial law to alert citizens to what he characterized as an "unconstitutional parliamentary dictatorship" by the then-opposition Democratic Party, alleging election fraud and government paralysis due to budget cuts and impeachment proceedings. His defense argued he deployed minimal, largely unarmed troops with no intent to suppress parliament or disrupt constitutional order.
Related Sentences
The court also convicted and sentenced several former military and police officials involved in enforcing the martial law decree:
- Ex-Defense Minister Kim Yong Hyun: Sentenced to 30 years in prison for his central role in planning and mobilizing the military for the measure.
- Former Prime Minister Han Duck-soo: Sentenced to 23 years in prison for actions related to legitimizing the decree, falsifying records, and perjury. He has appealed his verdict.
Legal Context
South Korea has maintained a de facto moratorium on capital punishment since 1997, with no executions taking place since that year. A precedent exists from 1996 when former military dictator Chun Doo-hwan was sentenced to death for a 1979 coup, which was later commuted to life imprisonment and followed by a presidential pardon. Yoon is the first former South Korean president to receive a life sentence since Chun Doo-hwan.
Yoon Suk Yeol's Other Sentences
Obstruction, Abuse of Power, and Document Falsification
In a separate proceeding, the Seoul Central District Court sentenced Yoon to five years in prison for charges including obstruction of official duties, abuse of power, falsification of official documents, and destruction of evidence. This verdict was the first of four trials he faced concerning the martial law attempt.
Judge Baek Dae-hyun stated that Yoon failed to uphold the Constitution and the rule of law as president, describing Yoon's culpability as "extremely grave." The court found that Yoon mobilized presidential security officials to block authorities from executing an arrest warrant at his residence, failed to consult a legally required full Cabinet meeting before declaring martial law, and signed backdated documents to create a false appearance of proper cabinet approval.
On appeal, the Seoul High Court increased this sentence to seven years, finding him guilty on all counts, including reversing a lower court's partial acquittal on abuse-of-power charges. Yoon has appealed this verdict.
Additional Charges
Prosecutors in another ongoing trial have alleged that Yoon attempted to provoke military conflict between South and North Korea to justify martial law. This trial will investigate whether Yoon ordered drone flights into North Korea to induce military conflict.
Kim Keon Hee's Sentencing
Verdict and Sentence
The Seoul High Court increased Kim Keon Hee's prison sentence from 20 months to four years on appeal. Kim was convicted of receiving gifts, including a Graff diamond necklace and Chanel bags, from the Unification Church, and of involvement in a stock price manipulation scheme. The appeals court found her guilty of the stock price manipulation charge, reversing the lower district court's acquittal on that count.
Indictment Details
Independent counsel Min Joong-ki's team had requested a 15-year prison term on charges that included bribery, stock price manipulation, and political funding law violations. The lower court acquitted Kim of the stock price manipulation and political funding law violation charges due to insufficient evidence.
Statements
The Seoul High Court stated that a first lady, being closest to a president, represents the country and has significant influence, and that Kim failed to meet public expectations for integrity. Kim's lawyers announced they will appeal the ruling to the Supreme Court, arguing the investigation was politically motivated.
Timing of Sentencing
Kim's sentence from the Seoul High Court was delivered after the initial 20-month sentence from the Seoul Central District Court. The four-year sentence is the final ruling before any potential appeal to the Supreme Court.

The martial law attempt was the first of its kind in South Korea in over 40 years, drawing comparisons to the country's history of military-backed dictatorships in the 1970s and 1980s.
Lee Jae Myung, upon becoming president, appointed three independent counsels to investigate allegations involving Yoon, his wife, and their associates.
Four former South Korean presidents (Roh Tae-woo, Chun Doo-hwan, Park Geun-hye, and Lee Myung-bak) have been imprisoned for charges ranging from bribery to insurrection after leaving office. All were eventually released via special pardons. Yoon led the prosecution of Park Geun-hye in 2018, who received a 20-year sentence for corruption before being pardoned. Yoon also pardoned Lee Myung-bak.
Political parties are advancing an insurrection pardon prohibition bill through parliament, though its passage is not yet finalized.
All parties have the option to appeal the respective verdicts to the Supreme Court of South Korea.
