SEOUL — A South Korean appellate court on Wednesday increased the prison sentence for former President Yoon Suk Yeol from five to seven years on obstruction of justice and related charges stemming from his failed 2024 martial law declaration, according to multiple news reports.
The Seoul High Court, in a live-televised ruling, found Yoon guilty of obstructing investigators from detaining him last year, among other offenses. Special prosecutors had sought a 10-year term.
The ruling was the first by the Seoul High Court's newly-formed insurrection division, a trial body launched in February 2026 to handle cases linked to Yoon's martial law bid, Yonhap News reported.
Coverage comparison
News agencies and media outlets covering the verdict reported the core facts consistently: the sentence increase, the charges, and the context of Yoon's larger legal entanglements. Deutsche Welle (카) and the South China Morning Post (SCMP) both framed the sentence enhancement with a neutral tone, quoting the presiding judge's remark that the defendant sought to obstruct lawful warrants execution and that the consequences were "highly reprehensible." SCMP also noted the judge's observation that the acts were “unacceptable in a society of law and order."
Yonhap, South Korea's national wire service, offered the most granular details on the court's reasoning and the subsequent legal steps. Several of its dispatches noted that the appellate court upheld the lower court's guilty verdict on most charges, but added that it also found Yoon guilty of exercising false official documents—a charge the lower court had acquitted him of—and increased the penalty accordingly. Yonhap also reported that the special counsel's team filed a Supreme Court appeal on Thursday, aiming to reinstate the 10-year sentence they had sought, while Yoon's lawyers on Wednesday immediately vowed to appeal the ruling, calling it "unacceptable."
All sources agreed that the original conviction had found Yoon used presidential security agents to block his arrest in January 2025, which corresponded to the obstruction-of-justice charge.
Key Claims
Across all six articles, the core factual claims were unanimous:
- The Seoul High Court increased Yoon's sentence in the obstruction case from five to seven years, as reported by Reuters (via Deutsche Welle), SCMP, and all Yonhap pieces.
- Yoon was previously found guilty by a lower court in January of using presidential security agents to block his arrest—a finding sustained on appeal.
- The appellate court upheld the lower court's guilty verdict but overturned some acquittals, reducing the prosecutors' recommended sentence from ten to seven years.
- Yoon's total legal jeopardy remains broad: beyond the obstruction case, he faces eight separate trials; most notably, in February 2026 he was sentenced to life imprisonment for leading an insurrection--the charged crime linked directly to his martial law declaration.
- Yoon made his attempt to impose martial law on December 3, 2024, in a surprise late-night televised address; the decree lasted about six hours before lawmakers rushed to the assembly and voted it down in an emergency session.
- Both Yoon and the special counsel have appealed to the Supreme Court—Yoon's attorneys calling the ruling "unacceptable" and the special counsel escaling to contest his acquittal on the trivial charge of exercising a false official document.
Perspectives
The legal saga involving Yoon has several broad angles:
- Legal (court and prosecutors): The court described obstruction as “highly reprehensible,” and the special counsel position was that seven years was insufficient, demanding ten. They filed a direct appeal to the Supreme Court.
- Defense/Defendant: Yoon's legal team called the verdict "unacceptable" and pledged to appeal to the Supreme Court, arguing among the court order that the arrest warrants were based in an "unlawful investigation."
- Public and Domestic: The ruling was covered as a high-profile political and legal event of national interest, with South Korea's public network broadcasting the verdict live, and press photographs showing citizens watching on screens at Seoul Station.
- Wider context: Yoon is also facing separate proceedings on allegations of corruption involving his wife, Kim Keon Hee, who was reported (by Deutsche Welle's covering) to be sentenced for corruption crimes, and trials regarding other accusations within his presidency.
