South Korean Court Sentences Former President Yoon to Seven Years for Obstruction of Justice

SEOUL, South Korea — A South Korean appeals court on Wednesday sentenced former President Yoon Suk Yeol to seven years in prison for obstruction of justice and procedural violations related to his brief imposition of martial law in December 2024.

The Seoul High Court found that Yoon bypassed legally required Cabinet procedures before declaring martial law and later resisted lawful attempts to arrest him. The conviction comes on top of a life sentence Yoon already received on rebellion charges stemming from what prosecutors described as an attempted self-coup that triggered South Korea’s most serious democratic crisis in decades.

Judge Yoon Sung-sik specifically cited the former president’s failure to convene a proper Cabinet meeting before the martial law declaration, falsifying documents to conceal this omission, and deploying presidential security forces “like a private army” to resist arrest following his impeachment.

“The defendant violated the constitutional rights of nine Cabinet members by either failing to notify them or simulating a formal meeting with only select officials,” Judge Yoon stated during the verdict reading. The former president remained silent throughout the proceedings.

Yoo Jeong-hwa, one of Yoon’s legal representatives, expressed disappointment with the ruling and confirmed the team would appeal to the South Korea’s Supreme Court. Yoon has also appealed his life sentence.

The appeals court ruling overturned a partial acquittal from a lower court, which had sentenced Yoon to five years in January but cleared him of some abuse-of-power charges related to the Cabinet meeting. The Seoul High Court found him guilty on all counts, increasing his sentence to seven years.

The December 3, 2024 martial law declaration, though brief, plunged South Korea into political turmoil, disrupting diplomatic relations and sending financial markets into volatility. The crisis only subsided after liberal leader Lee Jae Myung won a special presidential election in June 2025.

Yoon’s political downfall began when the liberal-controlled National Assembly impeached him on December 14, 2024. His formal removal from office came four months later when the Constitutional Court upheld the impeachment in April 2025.

The obstruction of justice charges stem from a tense standoff that occurred in January 2025, when Yoon refused to comply with a Seoul court’s detention warrant. Dozens of investigators who arrived at the presidential residence were blocked by security forces and vehicle barricades. Authorities eventually detained him later that month, though a court ordered his temporary release in March. He was re-arrested in July 2025 and has remained in custody since then.

The ruling against the former president came just one day after the same court increased his wife Kim Keon Hee’s sentence to four years on separate charges. Kim was convicted of accepting luxury gifts from the Unification Church, which prosecutors said sought political favors from Yoon’s administration, and involvement in a stock price manipulation scheme.

Legal troubles continue to mount for the former leader. Last week, prosecutors in yet another trial requested a 30-year prison term for Yoon over allegations that he deliberately escalated tensions with North Korea by ordering drone flights over Pyongyang in 2024, allegedly to create conditions that would justify imposing martial law domestically.

The series of criminal cases against Yoon marks an extraordinary reversal for a president who took office in 2022 as a former top prosecutor who had promised to uphold the rule of law. His fall from power adds to South Korea’s troubled history with presidential transitions – multiple former South Korean presidents have faced legal consequences after leaving office, though none under such dramatic circumstances.

Political analysts note that the case has deepened polarization in South Korean society, with Yoon’s supporters staging regular demonstrations outside courthouses during his trials, believing the charges to be politically motivated. Meanwhile, government officials under President Lee have emphasized that the proceedings represent the proper functioning of judicial checks on executive power.
