South Korean Ex-Leader Is Sentenced to Life in Prison
Former President Yoon Suk Yeol of South Korea was sentenced to life imprisonment on Thursday after being found guilty of leading an insurrection when he declared martial law in 2024 and plunged the country into a constitutional crisis.
Mr. Yoon, 65, has been on trial since April on a series of criminal charges stemming from that short-lived martial law declaration. The judges at the Seoul Central District Court on Thursday ruled on the most serious of them: being the ringleader of an insurrection. Prosecutors had demanded a death sentence.
Mr. Yoon denied the charges against him. He has a week to appeal the verdict and ruling.
South Koreans met the specter of military rule again when Mr. Yoon declared martial law on the night of Dec. 3, 2024. He said it was necessary to eliminate what he called “anti-state forces” within the opposition-dominated National Assembly. He called the legislature a “den of criminals” who he said used their parliamentary majority power to paralyze his government.
His decree banned all political activities and placed the news media under military control. Armed troops raided the National Assembly and the National Election Commission. Prosecutors also accused Mr. Yoon of ordering troops to arrest his political enemies.
Public outrage almost immediately scuttled Mr. Yoon’s attempt to rule by martial law. As soon as they saw Mr. Yoon declare it on TV, citizens rushed to the National Assembly to confront the troops who had come to take over the legislature under the president’s orders. While the crowd held the troops back to prevent them from seizing its main chamber, lawmakers gathered inside and voted down his decree in the middle of the night.
Mr. Yoon was forced to withdraw it after six hours. But his power grab set off South Korea’s worst political crisis in decades, with its democracy undergoing a stress test as the country impeached the president, arrested those involved in his martial law, and elected a new leader, Lee Jae Myung.
Prosecutors said that what Mr. Yoon and his collaborators did during the short period of martial law was an act of insurrection. In separate rulings in recent weeks, two other panels of judges at the Seoul Central District Court have agreed, sentencing the former prime minister and home minister to 23 years and seven years in prison, respectively, on charges of collaborating with Mr. Yoon.
Mr. Yoon accused prosecutors of “writing fiction” when they accused him of committing insurrection. His declaration, he said, was a legitimate use of presidential power to alert South Koreans to the danger posed by his enemies in the political left.
