Overview
- The Supreme Court finalized the seven-year sentence on Thursday, July 9, 2026, dismissing appeals by both Yoon and prosecutors and making the obstruction conviction final.
- Justices affirmed findings that Yoon revised and destroyed the martial law proclamation and denied required Cabinet deliberation rights before the Dec. 3, 2024 declaration.
- The court upheld that the Corruption Investigation Office lawfully pursued insurrection-related allegations uncovered during its abuse-of-power probe, supporting the legality of its arrest effort.
- Courts found that presidential security forces blocked a January 2025 attempt to detain Yoon at the presidential residence, a fact central to the obstruction charge, and Yoon has been in custody since July 2025.
- Yoon’s lawyers said they will seek constitutional review and he remains subject to other major trials and appeals, including a separate life sentence for insurrection and a 30-year drone-related case, so legal and political fallout is ongoing.
