South Korean Ex-President Yoon Sentenced to Five Years in Prison for Martial Law Obstruction

Seoul, 16 January 2026
Former South Korean President Yoon Suk-yeol received a five-year prison sentence on 15 January 2026 for obstructing justice and abuse of power related to his failed martial law declaration in December 2024. This landmark ruling marks the first conviction in what will be four separate trials stemming from his controversial decree that plunged the nation into political crisis. The court found Yoon guilty of using presidential bodyguards to prevent his arrest and failing to consult his cabinet before declaring martial law. More significantly, he faces a potential death penalty in February’s insurrection trial, where prosecutors argue his actions constituted rebellion against the constitutional order. The verdict represents unprecedented accountability for a former South Korean president’s attempt to undermine democracy.

Court Delivers Historic Ruling

The Seoul Central District Court delivered its verdict on 15 January 2026, finding Yoon guilty of abuse of power, obstructing justice, and falsifying documents [1][2]. The presiding judge stated that Yoon’s actions had “plunged the country into political crisis” and criticised his consistent lack of remorse throughout the proceedings [1]. Prosecutors had initially sought a 10-year jail term, making the five-year sentence a relatively lenient outcome [1][2]. Both prosecution and defence teams have seven days to appeal the ruling, indicating this legal battle may continue well into 2026 [1].

Specific Charges and Evidence

The court convicted Yoon on three primary charges stemming from his December 2024 martial law attempt [1][2]. He was found guilty of using presidential bodyguards to prevent his arrest, failing to consult his cabinet before declaring martial law, and destroying falsified documents [1][2]. The judge emphasised that Yoon had “the duty to safeguard the constitution and law but turned his back on them” [2]. Approximately 100 of Yoon’s supporters gathered outside the courthouse during the 15 January verdict, demonstrating the continuing political divisions his actions have created [2].

Historical Context and Implications

This case represents the first insurrection-related charges against a former South Korean president since the 1996 trial of military leaders Chun Doo-hwan and Roh Tae-woo [6]. Prosecutors have compared Yoon’s actions unfavourably to historical precedents, stating his martial law attempt “tarnished the nation’s dignity far more severely than the military coup Chun and Roh staged in 1979” [3]. The complexity of accountability is evident in public opinion, with a December 2025 survey showing nearly 30% of South Koreans did not believe Yoon’s martial law declaration constituted insurrection [1][2]. Following Yoon’s impeachment and removal from office in April 2025, Lee Jae Myung was elected president, marking a significant political shift [6].

Multiple Trials and Ongoing Legal Proceedings

Yoon’s legal troubles extend far beyond the martial law charges, with eight separate criminal trials currently proceeding [4][5]. These include charges of perjury during former Prime Minister Han Duck-soo’s trial, involvement in obstructing investigations into a marine officer’s 2023 death, and allegations of meddling in the 2022 presidential elections [3]. The breadth of charges reflects what prosecutors describe as a pattern of constitutional violations and abuse of power. Three special prosecutor probes into Yoon, his wife, and alleged cover-ups have resulted in indictments of over 120 people [6]. South Korea has not executed anyone since December 1997, making the death penalty demand largely symbolic but constitutionally significant [3][6].
