South Korean Appeals Court Cuts Former Prime Minister Han Duck-soo’s Prison Term to 15 Years
5/7/2026, 1:27:40 PM
Sentence Reduction Overview
On 7 May 2026 the Seoul High Court reduced former Prime Minister Han Duck-soo’s prison term from 23 years to 15 years. The court upheld most convictions—engaging in essential activities of an insurrection, falsifying a presidential document and perjury—while lowering the penalty in light of Han’s five-decades of public service.
Background: Yoon Suk-yeol’s Martial Law Decree
In early December 2024 President Yoon Suk-yeol issued a decree that briefly suspended civilian government, cutting power and water to selected media outlets. Opposition lawmakers overturned the decree after roughly six hours, but the episode triggered a series of criminal prosecutions against senior officials, including Han.

Official Statements & Judicial Reasoning
Judge Lee emphasized the prime minister’s constitutional duty to curb unlawful presidential actions, noting Han “abandoned the grave responsibilities arising from the authority and position entrusted to him.” The court cited Han’s long service as a mitigating factor. Han denied all charges except perjury, asserting he “regretted not being able to stop Yoon” but “never agreed to it or tried to help.” Yoon, while denying wrongdoing, apologized for the “frustration and hardship” caused by the martial-law decree and affirmed the “sincerity and purpose” of his actions.
Criticism & Judicial Observations
The judgment highlighted Han’s failure to oppose Yoon despite prior exposure to authoritarian martial-law episodes in the 1970s-80s, describing this lapse as a “grave” breach of duty. Simultaneously, the court acknowledged limited evidence of Han’s active conspiracy, influencing the sentence reduction.
Verbatim Quotes
- “The defendant, as prime minister, had the responsibility to curb and control the president's wrongful execution of his power and help him legally exercise his authority,” — Judge Lee Seung-cheol
- “But he abandoned the enormous duty and joined the side participating in insurrection .... He committed crimes afterwards to cover up his guilt, so his crime is grave.” — Judge Lee Seung-cheol
- “We sentence the defendant to 15 years in prison.” — Judge Lee Seung-cheol
- “never agreed to it or tried to help.” — Han Duck-soo, in court filings
Implications for Rule of Law
The reduction underscores South Korea’s balancing act between holding senior officials accountable and recognizing mitigating personal histories. It also signals judicial willingness to scrutinize executive overreach while navigating political sensitivities surrounding the nation’s recent democratic backsliding.
Conflicting Reports & Gaps
All sources agree on the sentence reduction and the court’s rationale. Minor variations exist in phrasing of the judge’s comments, but no substantive contradictions are present. Details on the specific evidence linking Han to the safety minister’s plan to cut utilities remain limited.
What’s Next
Han’s legal team has announced a further appeal. Yoon continues to face multiple trials, including recent sentencing adjustments for obstruction of justice and related corruption charges against his wife, Kim Keon-hee. The outcomes will shape South Korea’s ongoing reckoning with the 2024 insurrection.
