In a landmark legal proceeding, South Korean prosecutors have formally requested a 10-year prison sentence for former President Yoon Suk Yeol regarding his controversial imposition of martial law in December 2024. The Seoul Central District Court heard arguments on Friday, December 26, 2025, marking a significant development in the ongoing judicial scrutiny of Yoon’s presidential actions.
The prosecution’s case centers on charges of obstruction of justice, alleging that Yoon systematically excluded cabinet members from critical martial law discussions and subsequently obstructed investigative procedures aimed at detaining him in January. This unprecedented declaration of martial law—the first in over four decades—triggered massive public demonstrations and precipitated a constitutional crisis within the National Assembly.
Yoon’s legal troubles escalated following his April removal from office by the Constitutional Court, which initiated multiple judicial proceedings against the former leader. In a statement earlier this month, Yoon defended his actions as necessary measures against what he characterized as ‘pro-China, pro-North Korea, and traitorous activities’ threatening national security.
The judicial panel is anticipated to deliver its verdict in January 2026, according to reports from Yonhap News Agency. Concurrently, Yoon faces three additional trials, including allegations of leading an insurrection—a charge that carries the potential for capital punishment upon conviction. These proceedings represent the most significant political reckoning in South Korea’s modern democratic history, testing the resilience of the nation’s constitutional framework and accountability mechanisms.
