The authorities in South Korea were expecting tens of thousands of protesters to descend on central Seoul on Friday as the nation’s Constitutional Court decides the fate of President Yoon Suk Yeol.
At least 14,000 police had been deployed to the area around the court, closing subway stations and locking down an area near a former royal palace that is popular with tourists and home to major businesses. Drones have been banned from the area, and schools, vendors and businesses have been ordered to close.
The first protests were set to start at 10 a.m. local time, ahead of a possible decision by the court that could come as early as 11 a.m. Mr. Yoon was not expected to attend the reading of the decision, which will determine whether he will be formally removed from office or returned to power.
Millions of South Koreans have protested, mostly peacefully, since Mr. Yoon briefly declared martial law on Dec. 3, plunging the nation into political upheaval and prompting lawmakers to impeach him. Mr. Yoon was detained in January on insurrection charges but released unexpectedly last month after a Seoul court said his detention was procedurally flawed.
Ahead of the Constitutional Court’s decision, which cannot be appealed, there have been growing worries that Mr. Yoon’s supporters will clash with those demanding he be removed from office. After his arrest in January, some of Mr. Yoon’s supporters overran a local court, breaking windows and threatening the judge hearing his case.
The police have created a fortresslike environment outside the Constitutional Court, placing 15-foot-tall metal barriers on either side of the main avenue approaching the complex in an effort to keep the two camps from confronting each other. Between the added security gates, police have parked dozens of buses and put up smaller metal fences to deter people from occupying the area.
The police response is not without precedent. In 2017, thousands of people tried to cross the police barricade near the court after it ruled that the president, Park Geun-hye, should be removed from office. At least four people died during the protests.
On the eve of the Constitutional Court’s ruling this time, South Korea’s interim leader, Han Duck-soo, called on the nation to respect the decision “with calm.”
“The government will not tolerate any illegal or violent acts,” he said on Wednesday, urging politicians not to incite violence. “This is a time to put the stability and fate of our community ahead of political interests.”
