On April 13, 2026, a highly anticipated appearance unfolded at the Seoul Central District Court, where Kim Geon-hee, the wife of former South Korean President Yoon Seok-youl, took the stand as a witness in the trial of former Justice Minister Park Sung-jae. The case, rooted in allegations surrounding involvement in the controversial December 3 emergency martial law incident, has gripped the nation’s attention for months. The courtroom was abuzz as Kim, known for her reserved public persona, entered the spotlight amid heavy media coverage and public scrutiny.
Kim Geon-hee’s entrance was notable not just for her status, but for the circumstances that followed. According to Channel A, she arrived at the courthouse wearing a white mask and black horn-rimmed glasses, escorted by correctional officers. This was hardly unusual in South Korea, where masks have remained commonplace in public life. However, the courtroom has its own rules. Presiding judge Lee Jin-gwan, overseeing the criminal division 33, addressed Kim before her testimony began, stating, “A witness may not wear a mask unless there is a reason such as an infectious disease. You must not wear a mask.” The judge’s tone was firm but not unkind, reflecting the seriousness of the proceedings and the need for transparency in a trial being broadcast to the public.
Kim hesitated for a moment, visibly uncomfortable. “I have a severe cold,” she explained, her voice wavering. The judge acknowledged her response but maintained the requirement. After a brief pause, Kim relented: “Yes, I’ll take it off.” She removed her mask, signaling her willingness to comply with the court’s expectations despite her obvious discomfort. This small exchange, captured by the press, quickly became a talking point, highlighting the tension between personal health concerns and the legal system’s demand for openness, especially in high-profile cases.
Once seated, Kim Geon-hee took the witness oath, declaring, “I swear to tell the truth without concealment or addition, and if I lie, I will accept the punishment for perjury.” This formal promise set the stage for a testimony that many hoped would shed light on the circumstances surrounding the December 3 martial law controversy—a political scandal that has raised difficult questions about the boundaries of executive power and the responsibilities of those in high office.
The heart of the inquiry focused on whether Kim Geon-hee had any prior knowledge of plans to declare emergency martial law, or if she had been involved in the appointment of Park Sung-jae as Justice Minister. According to both Channel A and other major outlets, Kim’s answers were unequivocal. When asked by the presiding judge, “Did former President Yoon ever speak to you about declaring emergency martial law?” Kim responded simply, “No.” The judge pressed further, “Was there any mention of it before or after the event?” Kim replied, “Not at all.” Her tone was described as calm but resolute, leaving little room for ambiguity.
The prosecution and the public alike had speculated about the extent of Kim’s knowledge or involvement, given her proximity to the former president and the gravity of the accusations against Park Sung-jae. Yet, Kim repeatedly denied any awareness or participation. “Did you have any involvement or hear anything when Park Sung-jae was appointed as Justice Minister?” the judge inquired. Kim answered, “No.” The clarity of her responses, delivered under oath, appeared to settle at least some of the swirling rumors, though critics and supporters alike continue to debate her credibility and the broader implications for the Yoon administration.
Adding to the courtroom’s drama, Judge Lee Jin-gwan reminded all present that the proceedings were being broadcast, underscoring the case’s significance and the public’s right to witness justice in action. The testimony itself lasted about 30 minutes, a relatively brief but intense session that left observers parsing every word and gesture. According to The Hankyoreh, Kim has often worn a mask during previous court appearances, but this was the first time she was publicly instructed to remove it, a move that some saw as symbolic of the transparency demanded in such a high-stakes trial.
Kim’s appearance was not just a legal formality—it was a moment of rare public visibility for a figure often shielded from direct scrutiny. Her testimony marked the first time she addressed, in a public forum, her knowledge of the events leading up to the December 3 martial law declaration. The timing was also significant: as reported by Channel A, she is scheduled to appear as a witness in the trial of her husband, former President Yoon Seok-youl, the following day. This marks their first court reunion in about nine months, ever since Yoon’s re-arrest in July 2025. The anticipation surrounding this meeting is palpable, with both supporters and critics eager to see how their testimonies might intersect or diverge as the legal process unfolds.
Throughout the proceedings, Kim maintained a subdued demeanor, speaking softly and choosing her words carefully. According to multiple reports, she appeared to be under significant stress but did not waver in her denials. The courtroom atmosphere was tense, with every exchange scrutinized by the press and legal teams alike. The judge’s insistence on mask removal, while rooted in legal protocol, also served as a metaphor for the broader demand for transparency and accountability in the ongoing investigation.
The December 3 emergency martial law case has become a touchstone for debates about the limits of executive authority in South Korea. Park Sung-jae, the former Justice Minister at the center of the trial, faces charges of participating in a plot to impose martial law—an act that, if proven, would represent a grave abuse of power. The investigation has cast a long shadow over the Yoon administration, prompting renewed calls for institutional reforms and greater oversight of high-ranking officials.
For many South Koreans, the sight of Kim Geon-hee on the witness stand—mask off, answering questions about one of the most consequential political scandals in recent memory—was a powerful reminder of the stakes involved. The case is far from resolved, and as the trials continue, the nation watches closely, aware that the outcomes could shape public trust in government and the rule of law for years to come.
As the legal drama continues, all eyes turn to the upcoming testimony of former President Yoon Seok-youl himself. The next chapter in this unfolding saga promises to be just as consequential, as the courts seek answers and the public demands accountability from those who once held the nation’s highest offices.
