South Korea's former Justice Minister Park Sung-jae was sentenced to 25 years in prison on Monday, 22 June after the Seoul Central District Court found him guilty of playing a key role in an insurrection linked to former President Yoon Suk Yeol's short-lived martial law declaration. The sentence exceeded the 20-year term sought by the special counsel's team and was followed by Park's immediate detention, with the court citing concerns over potential evidence destruction.

What the Court Found

The court convicted Park on two charges: playing a key role in an insurrection and abusing his power. Prosecutors argued that Park had convened a senior ministry officials' meeting in the immediate aftermath of Yoon's 3 December 2024 martial law declaration — a meeting allegedly aimed at reviewing the dispatch of prosecutors to a martial law-supporting body and assessing the capacity of correctional facilities, reportedly to accommodate politicians and key figures expected to be arrested.

Park was also found to have ordered ministry officials responsible for imposing travel bans to report for duty during the crisis period.

The Court's Verdict in Its Own Words

'The defendant ultimately turned his back on his duty of upholding the Constitution at the idea that the insurrection could succeed, choosing to instead take part in it,' the court stated in its ruling.

Where Park Fits in the Broader Convictions

Park's sentencing adds to a growing list of senior officials convicted in connection with Yoon's martial law bid. Former Prime Minister Han Duck-soo and former Defence Minister Kim Yong-hyun have also been found guilty of playing a key role in the insurrection. In February, Yoon himself was sentenced to life imprisonment for leading the insurrection; he has since appealed that ruling.

Notably, this is the first time in South Korea's modern democratic history that a sitting president's martial law declaration has triggered cascading criminal convictions across an entire Cabinet tier — a constitutional rupture with few precedents in the region.

Charges Dismissed and Pending Matters

The court dismissed additional charges against Park for allegedly violating the anti-graft law, ruling that the matter fell outside the special counsel's investigation mandate. A separate set of charges — that Park gave inappropriate orders to subordinates at the request of Yoon's wife, Kim Keon Hee, in May 2024, to check details of a prosecution inquiry into her corruption allegations — had also been part of the indictment but were addressed separately.

What Comes Next

With Park now in custody and Yoon's appeal pending, South Korea's courts face continued pressure to resolve the full legal fallout of the December 2024 martial law episode. The special counsel's investigation remains active, and further proceedings involving other officials connected to the incident are expected in the months ahead.
