South Korea's constitutional court is reviewing the impeachment of President Yoon Suk-yeol after parliament voted to oust him for a controversial martial law order. The court has six months to decide on his removal or reinstatement. Following the martial law announcement, protests erupted in Seoul, leading to political instability and the resignation of PPP chair Han Dong-hun. The court's decision is critical, as it requires a unanimous ruling to uphold the impeachment, while Prime Minister Han Duck-soo temporarily leads the country.
