Former President Yoon Suk-yeol remains in custody following his February 2026 life sentence for insurrection and abuse of power related to the December 2024 martial law declaration. Multiple parallel appeals, including the insurrection case with final arguments scheduled through early November 2026 and separate proceedings on drone operations and election law violations, continue without any rulings or procedural developments that would trigger release. Prosecutors have pressed for upheld 30-year terms in the drone case and dismissal of Yoon's appeals elsewhere, while courts have advanced proceedings under statutory timelines but shown no movement toward bail, acquittal, or sentence suspension. These factors sustain trader consensus that custody will extend past 2026.
