The constitutional court has overturned the impeachment of South Korean prime minister Han Duck-soo, reinstating him as acting president amid ongoing political upheaval. Han was removed from office after president Yoon Suk Yeol declared martial law late last year, suspending civilian legal processes and triggering a national crisis. After Yoon's suspension by lawmakers on 14 December, Han took over presidential duties - only to be impeached himself less than two weeks later for allegedly undermining the constitution. The opposition Democratic Party accused him of aiding Yoon’s martial law plan and refusing to appoint constitutional court justices or pass a bill investigating First Lady Kim Keon-hee. However, the court found no evidence to support these accusations; only one of eight judges supported the impeachment. Han welcomed the ruling, calling it ‘wise’. The nation now awaits the court’s decision on whether Yoon will be impeached.
