South Korea’s Constitutional Court could soon rule on whether to dismiss or reinstate impeached President Yoon Suk Yeol. The court has been deliberating whether to formally end Yoon’s presidency since the liberal opposition-controlled National Assembly in December voted to suspend him. Yoon is also facing a separate criminal trial after his arrest and indictment by prosecutors in January for alleged rebellion in connection with his martial law decree. If the court rules against him, he will be officially thrown out of office and a national election will be held for a successor within two months. If it rules for Yoon, he would return to presidential duties, but it was earlier unclear whether or how soon he might return to office. The biggest issue is why Yoon sent hundreds of troops and police to the parliament after declaring martial law. The Constitutional Court’s endorsement of Yoon’s impeachment would confirm his violation of the constitution and could help increase prospects for his conviction of rebellion, said Park SungBae, a lawyer specializing in criminal law. But a rejection would mean that the Constitutional Court believed Yoon wasn’t serious enough to warrant dismissal, or maybe it burdensome’s alleged rebellion at criminal trial, Park said.
