A South Korean court has overturned the impeachment of Prime Minister Han Duck-soo, reinstating him as the country's acting leader following the martial law incident. The Constitutional Court's decision, with only one judge voting against it, precedes a similar ruling on President Yoon Suk Yeol's impeachment. This is a significant development as the court addresses issues related to Yoon's short-lived martial law decree, which led to a major constitutional crisis in South Korea. The decision has caused division in the nation, with protesters gathering in Seoul awaiting the outcome of Yoon's impeachment. Han was suspended by lawmakers in December for not appointing new judges to the Constitutional Court to support Yoon's impeachment, and for allegedly being involved in the martial law declaration. The court found Han's conduct to be a legal violation but not enough to warrant his removal from office. Following the court's ruling, South Korea's stock market saw positive gains, and Han will resume his duties as acting president, replacing Finance Minister Choi Sang-mok. Opposition parties in parliament have moved to impeach Choi for delaying the appointment of a court justice approved by the assembly.
