The court concluded its hearings on February 25, during which President Yoon defended his December declaration of temporary martial law, asserting that it was necessary to eliminate “anti-state” elements, though he emphasized that he did not intend to impose full emergency military rule.

Kim Min-seok, a member of the Democratic Party, expressed concern, stating, “The country and the people are nearing a breaking point,” and called for a prompt and responsible decision from the court. He further remarked that any additional delay would be “irresponsible.” For context, former President Park Geun-hye was removed from office just 11 days after the final arguments in her 2017 impeachment trial.

Mass protests have occurred in Seoul, with many citizens demanding Yoon’s removal and expressing frustration with the delay, which has contributed to confusion and uncertainty.

Yoon was impeached by the Democratic Party-controlled parliament in December, charged with violating his constitutional duties and posing a significant threat to the rule of law. He is also facing a separate criminal trial for allegedly leading an insurrection, an offense punishable by death or life imprisonment.

The fallout from Yoon’s martial law declaration has deepened political rifts between conservatives and liberals, further dividing public opinion and placing significant strain on governmental institutions. Several senior military officials have been relieved of their duties and are facing criminal charges in connection with the martial law decree. The trial of former Defense Minister Kim Yong-hyun on insurrection charges is set to commence on Monday.

In the wake of Yoon’s impeachment and suspension on December 14, Prime Minister Han Duck-soo briefly assumed the role of acting president but has since also been impeached. Currently, Finance Minister Choi Sang-mok is leading the country.

Yoon was transported from the Seoul Detention Center to the court in a justice ministry motorcade, with police buses stationed outside the courthouse to maintain security. Prosecutors pushed for a swift trial due to the seriousness of the case, but Yoon’s defense team requested more time to review the evidence.

One of Yoon’s lawyers argued that he had no intention to disrupt the country, claiming the martial law declaration was meant to alert the public to the “legislative dictatorship” of the powerful opposition party. If convicted, Yoon could face a lengthy prison sentence for his decree, which alarmed the nation and sought to restrict political and parliamentary activities as well as control the media.

The declaration led to political chaos in South Korea, Asia’s fourth-largest economy and a key U.S. ally, with the prime minister also impeached and suspended, and high-ranking military officials indicted for their roles in the situation.

Yoon’s lawyers also requested the cancellation of his detention, arguing the investigation had been unlawful and that there was no threat of Yoon tampering with evidence. The court has not yet decided on the detention request but scheduled the next hearing for March 24.

In addition to his criminal trial, Yoon participated in a separate impeachment trial before the Constitutional Court in the afternoon, which is now in its final stages. Prime Minister Han Duck-soo, who has also been impeached, testified at the court. Han expressed his deep concern about the divisiveness caused by the extreme political climate surrounding the martial law period.

The Constitutional Court is reviewing the impeachment decision made by parliament on December 14 and will determine whether Yoon should be permanently removed from office or reinstated. Yoon and his legal team argue that his martial law decree was not meant to be fully implemented but was intended only as a warning to break the political deadlock. If Yoon is removed, a new presidential election will be held within 60 days.

Yoon, who had been holed up at his private residence on a hillside in Seoul, had managed to avoid arrest earlier this month when his security team successfully blocked an attempted operation by authorities. However, after nearly two weeks of mounting pressure and heightened tensions, the 63-year-old former leader finally surrendered to investigators from the Corruption Investigation Office for High-ranking Officials (CIO), which is spearheading the inquiry.

In a statement issued just before his voluntary surrender, Yoon described the investigation as “illegal” but acknowledged his decision to cooperate, saying it was made to avoid “unsavoury bloodshed.” His remark reflects the polarized political climate in South Korea, where tensions over his presidency have been running high since his controversial martial law declaration.

Yoon’s impeachment stems from his announcement of martial law in December, a move that critics said sought to extend his grip on power after losing a key legislative battle. The declaration, which was seen by many as a step toward an unconstitutional attempt to retain office, prompted the swift intervention of the South Korean legislature. In the aftermath, Yoon was stripped of his duties, and the national crisis deepened as investigations into his actions began.

Since the impeachment, Yoon has been in a state of partial political limbo, refusing to vacate his residence despite the stripping of his presidential powers. Throughout this period, he was guarded by a sizable team of security personnel who ensured his physical safety and kept authorities at bay. The standoff reached its climax on Wednesday when more than 3,000 police officers were deployed to his home to execute his arrest.

In an almost cinematic sequence, Yoon turned himself in early Wednesday morning, escorted by a prosecutor from his luxurious residence in the upscale district often referred to as “Seoul’s Beverly Hills.” The president, in a bid to avoid media attention, entered the CIO offices through a back entrance while police surrounded the building. As he was being interrogated inside, the country’s attention was diverted by a separate, harrowing incident.

While Yoon was under questioning, an unidentified man in his 60s set himself on fire near the CIO offices. Fire services reported that the man was severely burned and unconscious upon being found. Authorities have not confirmed the man’s identity or whether he had any direct connection to the unfolding events surrounding Yoon’s arrest, but the act of self-immolation adds a tragic layer to an already volatile political situation.

Yoon’s arrest marks a significant moment in South Korea’s political history, where the line between democratic governance and authoritarian tactics has been fiercely contested. The impeachment, along with the subsequent arrest, exposes the deep divisions in South Korean society and government, raising questions about the future direction of the country’s leadership.

As the investigation into Yoon continues, the political atmosphere remains tense. Analysts suggest that Yoon’s arrest may trigger more protests or civil unrest, especially if the public perceives the investigation as politically motivated. Meanwhile, calls for greater accountability and transparency in government are growing louder, with many questioning the strength of South Korea’s democratic institutions in the face of such unprecedented turmoil.

With Yoon’s arrest and interrogation underway, the eyes of the nation and the international community are fixed on the developments in Seoul. How South Korea navigates the aftermath of this unprecedented political crisis will have lasting implications not only for its governance but also for its standing on the global stage.

However, one thing is clear: the political landscape in South Korea has been irrevocably altered, and the consequences of his actions will echo for years to come.
