Former South Korean President Yoon Suk Yeol Sentenced to Life in Prison

Seoul, South Korea – Former South Korean President Yoon Suk Yeol was sentenced to life in prison on Thursday, February 19, 2026, by the Seoul Central District Court. The conviction stems from his actions related to the declaration of martial law on December 3, 2024, which the court deemed an insurrection.

Insurrection Charges and Court Ruling

The court found Yoon guilty of mobilizing military and police forces in an attempt to seize control of the National Assembly and detain key political figures. Presiding Judge Ji Gui-yeon stated that deploying martial law troops to the National Assembly during a state of emergency constituted “rioting,” a crucial element in establishing the charge of insurrection. The judge further clarified that declaring martial law can be considered insurrection if intended to obstruct or paralyze constitutional institutions. abc7NY

Political Context and Constitutional Concerns

The court acknowledged the existing political tensions between Yoon’s administration and the opposition-controlled legislature. But, it ruled that these circumstances did not justify the imposition of martial law under the South Korean constitution. abc7NY

Lack of Remorse and Defense Response

Judges noted Yoon’s lack of remorse or acknowledgment of wrongdoing throughout the proceedings, a factor considered in determining the severity of the sentence. Yoon’s legal team criticized the ruling, labeling it “a mere formality for a predetermined conclusion.” Yoon Gab-geun, Yoon’s attorney, expressed concerns about the state of the rule of law and questioned whether an appeal would be pursued, stating, “The truth will be revealed in the court of history.” abc7NY

Immediate Aftermath and Legal Process

Following the ruling, Yoon was immediately taken into custody and transferred to the Seoul Detention Center. He will remain there pending the outcome of any appeals. If Yoon chooses to appeal, the case will proceed to the Seoul High Court for review of legal interpretations and factual findings, with a potential final appeal to the Supreme Court. abc7NY

Additional Charges and Public Reaction

While Thursday’s ruling specifically addressed the insurrection charge, other criminal cases related to the December 2024 martial law declaration, including allegations of abuse of power and obstruction of official duty, are still pending. In a separate case last month, Yoon received a five-year prison sentence for obstructing his arrest, marking the first criminal conviction linked to the crisis. abc7NY

According to Leif-Eric Easley, a professor at Ewha University in Seoul, the sentencing does not represent a national catharsis, as many Koreans have already moved on emotionally from the former president. He as well noted that the televised verdict does not signify closure, as numerous cases and appeals related to Yoon’s actions are still to be adjudicated. abc7NY
