Seoul (TDI): In a defining moment for South Korea’s modern history, a Seoul court has convicted former President Yoon Suk-yeol of insurrection and sentenced him to life in prison after finding that his actions in December 2024 were an attempted overthrow of the constitutional order.
The verdict, delivered on Wednesday, brought with it intense political debate and large public demonstrations. The case stems from Yoon’s sudden and unexpected declaration of martial law on the 3rd of December 2024, a move he defended as necessary to break legislative deadlock and “root out anti-state forces.”
The court, however, ruled that his decision exceeded constitutional authority by mobilizing military and police forces to surround the National Assembly, block lawmakers, and attempt to detain political opponents; actions the judges said amounted to insurrection.
Prosecutors had sought death penalty but the court opted for life imprisonment, citing South Korea’s longstanding prohibition on executions and the gravity of Yoon’s conduct.
Yoon’s conviction marks the first time a democratically elected South Korean president has been found guilty of such a charge. He was impeached shortly after declaring martial law, removed from office by the Constitutional Court in April 2025, and detained in July of the same year.

Alongside Yoon, several senior officials including his former Defense Minister, who received a 30-year sentence, were convicted for their roles in implementing the martial law order. Outside the courtroom, supporters and critics held rallies that highlighted deep political divisions within the country.
To understand this verdict, it is crucial to trace the background of the crisis. Yoon rose to prominence as a conservative prosecutor known for taking on high-profile corruption cases, later winning the presidency with strong backing from right-leaning voters.
By late 2024, his administration faced fierce opposition in a National Assembly controlled by liberals, stalling his agenda. On 3rd December, Yoon announced a dramatic imposition of martial law, deploying security forces.
Within hours, lawmakers had overturned his decision, and mass protests erupted nationwide. Yoon lost his grip on power rapidly, resulting in impeachment, and a series of trials for multiple charges tied to his actions during the crisis.
Despite moments of intense political polarization that pushed the country to the brink in late 2024, the judiciary and legislature ultimately affirmed that no leader, not even a sitting president, is above the rule of law.
