Former President of South Korea, Yoon Suk Yeol, has been sentenced to life imprisonment for attempting to impose military rule. Yoon’s actions to deploy military troops and arrest politicians on December 3, 2024, were deemed an insurrection that severely harmed South Korea's democracy, according to Judge Ji Gwi-yeon.

Prosecutors had initially sought the death penalty, but Yoon received a life sentence. The martial law attempt left the nation deeply divided, with large crowds of Yoon’s supporters and opponents gathering outside the court during the sentencing. Supporters were visibly upset, while anti-Yoon protesters demanded a harsher penalty.
Yoon's lawyers disputed the verdict, claiming it lacked evidence and was predetermined. An appeal from either side could send the case to the Supreme Court, delaying finalization.
Yoon shocked the nation with his unexpected martial law declaration, claiming a need to protect against "anti-state" forces. The motives were believed to stem from domestic issues, including opposition party challenges and corruption allegations involving his wife. The martial law was quickly overturned after legislative intervention, leading to Yoon’s impeachment and subsequent legal troubles.
Former Prime Minister Han Duck-soo received a 23-year sentence, and ex-Defense Minister Kim Yong-hyun was jailed for 30 years for advising the martial law. Other top officials were sentenced for their involvement in this "top-down insurrection."
Security was heightened outside the court, with extensive police deployment ensuring order. Inside, Yoon argued his presidential right to declare martial law, citing threats from opposition parties. However, the court found insufficient proof that Yoon premeditated the declaration a year in advance.
The ruling Democratic Party criticized the court for not issuing a death sentence, alleging it undermined judicial justice. Despite their stance, South Korea hasn’t executed anyone since 1997, rendering a death penalty essentially a life sentence. Yoon faces more trials related to these events, and although similar past cases have led to eventual pardoning, it remains uncertain if Yoon will receive clemency.
