South Korea’s acting President Han Duck-soo has called on the nation to remain calm and respect the rule of law ahead of a pivotal Constitutional Court ruling on the impeachment of President Yoon Suk Yeol, scheduled for April 4.

Speaking at a national safety meeting on Wednesday, Han warned against political provocation and pledged a strong government response to any unlawful behavior.

“No matter the outcome, we must accept the decision peacefully and in accordance with the law,” Han said. “If we unite with wisdom and strength, we can navigate through this period of uncertainty and division.”

The Constitutional Court is set to rule on whether Yoon should be permanently removed from office or reinstated. The president was impeached by the National Assembly on December 14 for allegedly breaching the constitution by declaring martial law without adequate justification. If the court upholds the impeachment, a presidential election must be held within 60 days.

In anticipation of potential unrest, authorities have bolstered security measures around the Constitutional Court. Interim National Police Chief Lee Ho-young said police would establish a high-security perimeter starting at midnight before the decision is announced. Demonstrators on both sides will be separated, and access to the court area will be tightly controlled.

Lee also warned that police would not hesitate to arrest anyone engaging in violence, vandalism, or intimidation of court officials. The security crackdown follows a January incident in which pro-Yoon protesters stormed a court building after his pretrial detention was extended.

Acting President Han has also instructed law enforcement to ensure the safety of the court’s justices in the days leading up to the ruling.

Meanwhile, political tensions continue to escalate. On Wednesday, opposition lawmakers—who hold a parliamentary majority—introduced a motion to impeach Finance Minister Choi Sang-mok. Choi, who previously served as acting president, drew sharp criticism for vetoing legislation and declining to appoint a Constitutional Court justice approved by lawmakers.

The twin impeachment battles have deepened South Korea’s political divide and raised questions about the future direction of its democratic institutions.
