A South Korean appeals court on Wednesday sentenced ousted President Yoon Suk Yeol to seven years in prison for obstruction of justice and related charges tied to his resisting arrest and the Cabinet process before his brief martial law declaration in December 2024.
Judge Yoon Sung-sik of the Seoul High Court said Yoon bypassed a legally required full Cabinet meeting before declaring martial law, falsified documents to conceal that lapse, and used security officials “like a private army” to resist law enforcement efforts to arrest him after his impeachment. Yoon stood quietly as the verdict was delivered and made no comment.
Yoo Jeong-hwa, one of Yoon’s lawyers, called the ruling “very disappointing” and said the legal team would appeal to the Supreme Court.
A lower court in January sentenced Yoon to five years in prison, but partly acquitted him of abuse-of-power charges tied to the Cabinet meeting, ruling he was not responsible for the absence of two invited members.
The Seoul High Court reversed that acquittal, finding him guilty on all counts. It ruled that he violated the rights of those two members and seven others who were not notified by convening only a limited group to resemble a formal meeting.
Yoon’s Dec. 3, 2024, martial law decree triggered a political crisis that disrupted domestic politics, senior-level diplomacy, and financial markets. He was suspended from office on Dec. 14, 2024, after the liberal-led legislature impeached him, and the Constitutional Court removed him from office in April 2025. The political turmoil eased after liberal rival Lee Jae Myung won an early presidential election in June.
After his suspension, Yoon refused to comply with a Seoul court warrant for questioning. In early January 2025, dozens of investigators who went to the presidential residence were blocked by presidential security forces and vehicle barricades. He was detained later that month, released by another court in March, and re-arrested in July.
He remained in custody as multiple criminal trials continued.
The ruling came a day after the same court increased to four years the sentence for Yoon’s wife, Kim Keon Hee, on charges including accepting luxury gifts from the Unification Church, which sought political favors from Yoon’s government, and involvement in a stock price manipulation scheme.
In a separate trial last week, prosecutors requested a 30-year prison term for Yoon over allegations that he tried to escalate tensions with North Korea in 2024 by ordering drone flights over Pyongyang to create conditions for martial law at home.
