Corée du Sud : la Cour suprême confirme la condamnation de l'ex-président Yoon à sept ans de prison

South Korea’s Supreme Court has finalized a significant legal decision by upholding a seven-year prison sentence against former President Yoon Suk Yeol. The ruling, delivered on Thursday, marks another major setback in the ongoing legal battles surrounding Yoon, who was ousted from office in early 2025 following his controversial attempt to impose martial law in December 2024. The court confirmed that Yoon was responsible for several serious offenses, including obstruction of government procedures, forgery of official documents, and misuse of presidential authority.

The case centered around Yoon’s failed effort to declare martial law in late 2024, an action that sparked widespread outrage and political turmoil. According to the court’s findings, Yoon convened a restricted group of ministers just before announcing the measure, thereby bypassing standard legislative protocols. He was further accused of fabricating a martial law decree signed by the prime minister, a document that bore forged signatures. Additionally, Yoon ordered officials to issue a misleading statement to foreign media, attempting to justify his actions. The court also found that he directed military personnel to erase evidence from secure devices, effectively trying to cover up his misconduct.

Prosecutors had initially requested a ten-year sentence, arguing that Yoon’s actions posed a severe threat to democratic governance. However, the initial trial in January resulted in a five-year sentence, which was later increased to seven years during an appeal hearing in April. The Supreme Court’s latest decision confirms this outcome, dismissing both the prosecution’s and Yoon’s legal teams’ appeals. A judge stated that the lower court’s ruling contained “no errors,” thus reinforcing the conviction.

Yoon’s legal representatives have expressed disappointment, claiming that the court reached its conclusion without adequate consideration. They intend to challenge the ruling on constitutional grounds and have announced plans to file a formal complaint. Despite these efforts, the Supreme Court’s decision is considered final, leaving little room for further legal maneuvering.

The martial law declaration itself remains one of the most contentious episodes in recent South Korean history. Yoon’s late-night broadcast in December 2024, which abruptly suspended civilian rule, led to immediate backlash from lawmakers, civil society groups, and international observers. The move lasted less than six hours before being overturned in an emergency parliamentary session. Nevertheless, the episode triggered nationwide protests, caused financial markets to fluctuate, and raised concerns among key allies such as the United States.

Beyond the martial law controversy, Yoon faces additional criminal charges. In a separate case, he was sentenced to 30 years in prison for orchestrating a drone attack on North Korea, an act intended to create a perceived crisis to justify his martial law declaration. Yoon has consistently maintained that his actions were driven by a desire to protect national interests and combat what he described as internal and external threats.

Yoon’s removal from power in April 2025 marked the end of his presidency, paving the way for new elections. These elections ultimately saw the victory of Lee Jae Myung, leader of the center-left Democratic Party. His election signaled a shift in South Korea’s political landscape, reflecting growing public dissatisfaction with Yoon’s leadership and policies.

As the legal proceedings continue, the implications of Yoon’s convictions extend beyond personal accountability. They underscore the challenges faced by South Korea in maintaining democratic norms amid high-stakes political decisions. With Yoon currently detained and facing multiple charges, the country watches closely as the legal system continues to navigate the complexities of past actions and their consequences.
