S. Korea’s Ex-Justice Minister Gets 25 Years for 2024 Martial Law Role

3 min readSources: JURIST

Park Sung-jae sentenced to 25 years for role in 2024 martial law attempt on June 22, 2026.

Why it matters: South Korea’s judiciary affirmed accountability for officials involved in unconstitutional power grabs, setting a precedent for legal and governance risks. Corporate legal teams should note the judicial limits on executive overreach and implications for compliance in politically volatile environments.

  • Park Sung-jae received a 25-year prison sentence on June 22, 2026, for insurrection related to 2024 martial law efforts.
  • The 2024 martial law lasted about six hours before South Korea’s National Assembly nullified it.
  • Former President Yoon Suk Yeol was impeached December 2024, removed April 2025, and sentenced to life plus 30 years for rebellion and related charges.
  • Other officials punished include former Defense Minister Kim Yong-hyun (30 years) and ex-Prime Minister Han Duck-soo (15 years after appeal).

On June 22, 2026, the Seoul Central District Court sentenced former Justice Minister Park Sung-jae to 25 years’ imprisonment for his involvement in the attempted declaration of martial law on December 3, 2024. Park was found guilty of insurrection under South Korea’s criminal code, specifying violations related to unconstitutional seizure of power during a political crisis (AP News) and corroborated by the South Korean Supreme Court’s publicly available rulings.

The martial law declaration stemmed from then-President Yoon Suk Yeol’s unproven allegations of election fraud. The National Assembly swiftly invalidated the six-hour-long martial law imposition. Park was convicted of directing security agencies to prepare mass arrests, travel restrictions, and probes targeting political opposition linked to the unrest (AP News).

Judges criticized Park for violating constitutional duties by enabling an unlawful power grab. Judge Lee Jin-gwan emphasized Park’s deliberate role in undermining democratic processes, while Judge Baek Dae-hyun noted his lack of contrition during proceedings, both factors contributing to a stringent sentence (Korean Judiciary Database).

President Yoon faced impeachment by the National Assembly in December 2024 and was formally removed in April 2025. Subsequently, he was sentenced to life imprisonment plus 30 years for rebellion and aggravating national security tensions (AP News).

Additionally, the former Defense Minister Kim Yong-hyun received a 30-year sentence, and former Prime Minister Han Duck-soo’s original 23-year sentence was reduced to 15 years after appeal. These rulings demonstrate South Korea’s legal system enforcing strict liability on high-level officials involved in unconstitutional actions.

This judicial response provides a precedent for legal professionals monitoring governance risks and compliance standards amid political instability. It underscores the legal boundaries on executive authority and the accountability mechanisms to preserve constitutional order in South Korea and comparable jurisdictions.

By the numbers:

  • 25 years — Prison sentence for ex-Justice Minister Park Sung-jae
  • 6 hours — Duration of declared martial law before legislative nullification
  • 30 years — Sentence for former Defense Minister Kim Yong-hyun

Yes, but: Some legal experts caution that these severe sentences may fuel political divisions and debates on judicial impartiality, especially as appeals proceed in South Korea’s courts.

What's next: Ongoing appeals by convicted officials are expected; courts will clarify interpretations of constitutional offenses regarding insurrection and power abuse.
