Yoon is also on trial on a criminal charge of insurrection, although he was freed from detention last week.
His martial law imposition and its fallout have widened deep social rifts between conservatives and liberals and put pressure on institutions and the military, which had found itself in a quandary over whether to enforce martial law.
Pro- and anti-Yoon demonstrators have been taking to the streets in their hundreds of thousands, week after week, since the crisis.
“Last week, I thought that the Constitutional Court would rule, but it didn’t. Then Yoon was released, making me incredibly frustrated,” said Song Young-sun, a 48-year-old protester. “So this week I came here, hoping that the Constitutional Court will rule on the impeachment case next week.”
In a Gallup Korea poll published on Friday, 58 per cent supported Yoon‘s impeachment, while 37 per cent opposed it.
“I hope that the judges of the Constitutional Court will make a precise judgment and dismiss the case,” said Kim Hyung-joon, a 70-year-old pro-Yoon protester.
