South Korean court overturns impeachment of Prime Minister Han Duck-soo, reinstating him as acting president

South Korea's Constitutional Court on Monday overturned the impeachment of Prime Minister Han Duck-soo, reinstating the nation's No. 2 official as acting leader, while not yet ruling on the separate impeachment of President Yoon Suk Yeol.

Many observers said Monday's ruling doesn't signal much on the upcoming verdict on Yoon, as Han wasn't a key figure in Yoon's martial law imposition. But it could still embolden Yoon's staunch supporters and ramp up their political offensive on the opposition.

Han became acting president after Yoon, a conservative, was impeached by the liberal opposition-controlled National Assembly over his Dec. 3 imposition of martial law that triggered a massive political crisis. But Han was impeached by the assembly as well in late December following political strife with opposition lawmakers.
