Verdicts and Sentences

Yoon Suk Yeol

Insurrection Charge

The Seoul Central District Court sentenced Yoon to life imprisonment with labor for leading an insurrection related to his martial law declaration. Judge Jee Kui-youn found that Yoon illegally mobilized military and police forces in an attempt to seize the National Assembly, arrest political opponents, and establish unchecked power.

Prosecutors had requested the death penalty. The court cited mitigating factors including the absence of casualties, Yoon's lack of prior criminal record, and his extensive public service.

This is the most serious charge Yoon faced; leading an insurrection carries a potential penalty of death or life imprisonment under South Korean law.

Obstruction, Abuse of Power, and Document Falsification

The Seoul High Court sentenced Yoon to seven years in prison for obstruction of justice, document falsification, and abuse of power. The court found that he bypassed a legally required full Cabinet meeting before declaring martial law, falsified documents to conceal the omission, and used security officials to resist arrest following his impeachment.

Separately, the Seoul Central District Court sentenced Yoon to five years in prison for similar charges including obstructing his arrest, failing to consult the full cabinet, and falsifying official documents.

Drone Flights Charge

The Seoul Central District Court sentenced Yoon to 30 years in prison for charges including aiding an adversary and abuse of power related to drone flights over Pyongyang in October 2024. The court found that the defendants sought to provoke North Korea into armed action to create a national emergency and justify martial law.

Yoon has appealed the life sentence and several other verdicts. He faces a total of eight criminal trials.

Kim Keon Hee

• The Seoul High Court increased Kim's prison sentence from 20 months to four years on appeal.
• She was convicted of receiving gifts including a Graff diamond necklace and Chanel bags from the Unification Church.
• She was also found guilty of involvement in a stock price manipulation scheme, for which she was acquitted in the initial district court trial.
• Kim has been in jail since August 2025.
• Her lawyers have announced they will appeal the ruling to the Supreme Court.

Other Convictions

• Former Defense Minister Kim Yong Hyun: Sentenced to 30 years in prison for his role in planning and mobilizing the military for the martial law decree.
• Former Prime Minister Han Duck-soo: Sentenced to 23 years in prison for attempting to legitimize the decree, falsifying records, and perjury. He has appealed the verdict.
• Former Interior Minister Lee Sang-min: Sentenced to seven years in prison for his role in the martial law implementation.

Legal Context

South Korea has not carried out an execution since 1997 and is classified by Amnesty International as "abolitionist in practice." The death penalty remains on the statute books for insurrection charges.

Former military dictator Chun Doo-hwan was sentenced to death in 1996 for his role in a 1979 coup, with the sentence later commuted to life imprisonment and followed by a presidential pardon.

Reactions

• Prosecution: Independent counsel Cho Eun-suk's team, which had requested the death penalty for Yoon, stated that the insurrection charge represents the most serious offense in the legal proceedings.

• Defense: Yoon's lawyer described the obstruction verdict as "very disappointing" and stated the defense will appeal to the Supreme Court. Yoon has maintained his innocence, asserting that the martial law declaration was within his constitutional authority and intended to highlight what he characterized as obstruction by opposition parties.

• Public: Both supporters and critics of Yoon have held rallies outside the court. Security was heightened at the Seoul Central District Court during the verdicts.
