SEOUL, South Korea (AP) — Former South Korean President Yoon Suk Yeol was sentenced to five years in prison Friday, marking the first verdict in a series of eight criminal trials stemming from his controversial imposition of martial law in December 2024.
Yoon, who was impeached, arrested, and removed from office following nationwide protests, was convicted of defying authorities, fabricating the martial law decree, and bypassing a legally mandated Cabinet meeting. The court emphasized that his actions violated constitutional procedures and undermined democratic institutions.
Judge Baek Dae-hyun, delivering the televised verdict, said a “heavy punishment” was necessary because Yoon showed no remorse and continued to offer “hard-to-comprehend excuses.” The judge added that the sentence was aimed at restoring the integrity of South Korea’s legal and political systems.
Background of the Martial Law Crisis
On December 3, 2024, Yoon abruptly declared martial law in a televised address, claiming he would neutralize “anti-state forces” and protect “the constitutional democratic order.” Security forces were deployed around the National Assembly, though lawmakers were still able to convene and vote down the decree. No significant violence occurred, but the move triggered South Korea’s most severe political crisis in decades, destabilizing markets and raising international concern.
Yoon has defended his actions, insisting the decree was intended to alert the public to legislative obstruction rather than to extend military rule. Investigators, however, viewed the decree as an attempt to consolidate power, charging him with rebellion, abuse of power, and other criminal offenses.
Independent Counsel Seeks Death Penalty in Rebellion Trial
In a separate trial focused on allegations of rebellion, an independent counsel has requested the death penalty, though legal experts predict the court is unlikely to impose it. South Korea has maintained a de facto moratorium on executions since 1997, and past precedent suggests a life sentence or a lengthy prison term is more probable.
Legal analysts note that South Korea has a history of pardoning former presidents convicted of serious crimes in the interest of national unity, including Chun Doo-hwan, who was initially sentenced to death over a 1979 coup and the 1980 crackdown on pro-democracy protests.
Ongoing Trials and Political Implications
Yoon faces multiple additional trials, including allegations of using drone flights over North Korea to provoke a pretext for martial law, manipulating an investigation into a 2023 marine’s drowning, and accepting improper election-related benefits. Observers suggest Yoon may continue to maintain a defiant stance to preserve political support, anticipating the possibility of a future pardon.
After Yoon’s ouster, his liberal rival Lee Jae Myung assumed the presidency following a snap election in June 2025. Lee subsequently appointed three independent counsels to investigate Yoon, his associates, and his family.
The sentencing marks a significant moment in South Korea’s contemporary political history, highlighting the delicate balance between presidential authority and democratic accountability.
