On August 8, the Seoul Central District Court rejected former Interior Minister Lee Sang-min’s request to overturn his arrest, keeping him in custody while special prosecutors continue investigating his alleged role in former President Yoon Suk Yeol’s short-lived martial law declaration.
The ruling came only hours after the court held a hearing on whether the arrest should remain in effect. According to the court, the case file and the suspect’s questioning did not justify releasing him. Lee had filed the review earlier in the day, after the court issued an arrest warrant the previous week on charges that included insurrection-related conduct, abuse of power and perjury.
The special counsel team led by Cho Eun-suk has argued that Lee did not act to stop Yoon from illegally declaring martial law in December and instead helped sustain the broader effort. Investigators have also said he instructed the police and fire service to cut power and water to media outlets that were critical of the administration, a step that would have increased pressure on news organizations already facing a volatile political moment.
Lee’s detention makes him the latest senior figure to be swept into the widening legal fallout from Yoon’s martial law episode. The source says he is being held at the Seoul Detention Center in Uiwang, just south of the capital. The court’s refusal to set aside the warrant means prosecutors retain the leverage they sought when they argued that Lee could destroy evidence if released.
The case also shows how the December crisis continues to reverberate through South Korea’s political and legal system months later. Yoon’s attempt to impose martial law lasted only a short time, but the investigation around it has expanded into allegations against multiple officials who were close to the former president or tied to the emergency decree in other ways.
Lee’s lawyers have reportedly denied most of the allegations. Even so, the decision to keep him in custody signals that the court saw enough risk in the special counsel’s case to let the detention stand while the investigation continues.
For prosecutors, the ruling preserves momentum in a case that has become one of the most politically sensitive in the country. For Lee, it means the challenge to his arrest failed quickly and decisively, and the legal battle now shifts from whether he should remain detained to the question of what investigators can prove about his conduct during one of the most consequential episodes of Yoon’s presidency.
The rapid ruling also shows how tightly the court is managing the review stage in politically sensitive cases. By moving from hearing to decision within hours, the judges kept the timeline short and signaled that the prosecution’s concerns about evidence and detention would not be treated lightly. That is important because the allegations around Yoon’s martial law episode are not limited to a single act; they extend to the chain of orders, the response of Cabinet members and the conduct of agencies that may have been involved in enforcing the decree.
For Lee, the failed challenge means his defense now has to work from inside detention while the special counsel continues building a case that reaches back to one of the most chaotic moments of Yoon’s presidency. The report’s reference to his alleged instructions involving media outlets adds a separate dimension to the inquiry, because it suggests the case is not just about whether martial law was declared, but also about what steps were taken to tighten control around it.
