SEOUL — A South Korean court on February 19, 2026, handed former President Yoon Suk Yeol a life prison sentence after convicting him of leading an insurrection tied to his dramatic attempt to impose martial law in December 2024. The verdict represents a landmark moment in the nation’s democratic history, addressing a crisis that shook public trust in government and triggered widespread political turmoil.
📍 Subhead: Historic Conviction After Failed Power Grab
Judges at the Seoul Central District Court ruled that Yoon’s declaration of martial law — meant to suppress opposition and give authorities expanded power — crossed constitutional boundaries and amounted to insurrection. Prosecutors sought the death penalty, but the court opted for life imprisonment because Yoon’s plan did not result in large-scale violence.
The court concluded that his attempt to deploy military and police forces around the National Assembly and disrupt its functions caused significant social and political disruption. Lawmakers overturned the decree within hours, but the legal consequences have continued.
📍 Subhead: Broader Legal Fallout and National Reaction
Alongside Yoon’s life sentence, several of his officials were also convicted. Former Defense Minister Kim Yong-hyun received a 30-year prison term for his role in planning and executing the martial law move. Other senior political and security figures linked to the episode received long sentences as well.
Reactions were sharply divided outside the courthouse. Supporters of Yoon protested the ruling, while critics praised the decision as upholding democratic norms. The case continues to fuel political debate nationwide, as Yoon’s defense team vows to appeal the decision.
📍 Subhead: Legacy of a Political Crisis
Yoon’s conviction stems from a crisis that began when he abruptly announced martial law in December 2024, claiming it was necessary to counter alleged threats within parliament. Legislators quickly reversed the order, impeaching him and removing him from office in 2025.
Political analysts say the ruling will reverberate through South Korea’s democratic institutions and raise questions about executive power limits, military neutrality, and legal accountability for national leaders.
