Former South Korean justice minister Park Sung-jae has been sentenced to 25 years in prison after being found guilty of involvement in ex-president Yoon Suk-yeol’s declaration of martial law in December 2024. The Seoul Central District Court determined that Park played a significant role in **Yoon's effort to seize power**, which included preparing for the detention of political opponents, according to Channel News Asia, South China Morning Post, and Los Angeles Times.

The martial law declaration, which was in effect for only around **six hours**, triggered chaos and protests across South Korea, ultimately leading to its quick annulment by the National Assembly. Lawmakers swiftly voted it down amid fears over Yoon's rapidly escalating authoritarianism, as detailed by reports from Channel News Asia and South China Morning Post.

During the emergency, Park **directed ministry officials** to assess prison capacity for potential anti-government arrests and pushed for the **mobilization of repression** against opposition figures. He also suggested preparing for travel bans and procedural investigations against those opposing Yoon, undermining constitutional duties, according to the court's findings mentioned in all three sources.

In the political fallout, Yoon was impeached and subsequently removed from office; he has already received **multiple sentences** totaling over 30 years for various offenses, including his attempts to use military drones to manipulate political tensions. The series of convictions against Yoon's cabinet members reflects a broader crackdown on those involved in the martial law enactment as reported by South China Morning Post, Los Angeles Times, and Channel News Asia.
