A former president of South Korea, Yoon Suk Yeol, has been sentenced to five years in prison by a court in Seoul for his involvement in obstructing authorities from arresting him after his failed attempt to impose martial law in December 2024. The court found Yoon guilty of using the presidential security service to impede the execution of an arrest warrant issued to investigate his martial law declaration. In addition to this, he was also convicted of fabricating official documents and failing to follow the legal procedures related to martial law.
This ruling marks the first legal outcome in the criminal case against Yoon concerning his botched martial law declaration. The presiding judge on the panel criticized Yoon for misusing his presidential influence to prevent the execution of lawful warrants by using officials from the Security Service for personal gain.
Yoon’s supporters gathered outside the court after the verdict was announced. His lawyer, Yoo Jung-hwa, stated that they would appeal the decision, expressing disappointment over what they perceived as a politicized judgment. In a separate trial, Yoon faces the possibility of the death penalty for allegedly orchestrating an insurrection by declaring martial law without valid justification.
Yoon has maintained that his declaration of martial law was a legitimate exercise of his presidential authority to highlight government obstruction by opposition parties. In a separate incident, Yoon barricaded himself inside his residence last year, leading to further obstruction charges, though he denied these accusations. He was eventually arrested in a subsequent attempt involving a large police presence, marking the first time a sitting president in South Korea had been detained.
Following his arrest, the South Korean parliament swiftly moved to overturn Yoon’s martial law decree and subsequently impeached him, stripping him of his powers. The Constitutional Court later removed Yoon from office in April 2025, citing violations of his presidential duties. Despite lasting only a few hours, Yoon’s attempt to impose martial law significantly impacted South Korea, a major Asian economy and a key U.S. ally known for its robust democratic system.
