Seoul High Court Raises Yoon’s Obstruction Sentence to Seven Years
On 29 April 2026 the Seoul High Court increased former President Yoon Suk-yeol’s obstruction-of-justice term from five to seven years, finding him guilty of using the presidential security service to block investigators, fabricating documents and convening an illegal cabinet meeting before his brief December 2024 martial-law decree. The televised ruling by a special martial-law division adds to Yoon’s life sentence for leading an insurrection tied to the same episode.
Background: Martial Law Attempt and Ongoing Trials
In December 2024 Yoon declared a six-hour emergency martial law, citing “anti-state” threats after his People Power Party lost its majority. Lawmakers revoked the decree within hours, leading to his impeachment on 14 December and removal in April 2025. Since July 2025 Yoon has faced eight trials, including the life-sentence case and the obstruction appeal.
Key Legal Actors
Presiding judge Yoon Sung-sik led the panel that set the seven-year term. Prosecutors asked for ten years, accusing Yoon of betraying trust and undermining constitutional order. Yoo Jung-hwa and Yoo Jeong-hwa called the verdict “incomprehensible” and “very disappointing,” and will appeal to the Supreme Court. Former first lady Kim Keon-hee received a four-year sentence for corruption-related offences.
Official Statements & Responses
The Seoul High Court said Yoon’s use of force to block an arrest warrant violated the law. Prosecutors called the judgment a deterrent against state abuse. Yoon’s lawyers argue the court applied “rigid legal principles” to political acts and will seek Supreme Court review. Yoon denies wrongdoing.
Criticism & Opposition
Defense attorneys labeled the ruling “incomprehensible” and “very disappointing,” saying the court ignored new evidence. Legal scholar Kim Gwang-sam warned that overturning acquittals creates “legal principles that contradict existing Supreme Court precedents.” Critics note the prosecution’s failure to secure ten-year term it sought.
Conflicting Reports & Gaps
Prosecutors sought a ten-year term, but the court imposed seven years, showing a gap between expectations and the ruling. The panel reversed two acquittals while keeping a not-guilty verdict on forged documents, leaving the scope of Yoon’s document-related offenses unclear. The Corruption Investigation Office for High-Ranking Officials has not issued comment.
