South Korea's Constitutional Court is poised to rule Friday on whether to dismiss or reinstate impeached conservative President Yoon Suk Yeol.

The Constitutional Court will announce on Friday whether Yoon Suk Yeol, who was impeached in December for declaring martial law, will be permanently removed from office or restored to power.

South Korea's interim leader called on the nation on Wednesday to calmly accept the decision from the Constitutional Court on the impeachment of President Yoon Suk Yeol, as police ramped up security around the court ahead of the ruling on April 4.
