South Korea's acting President Choi Sang-mok said on Tuesday he would immediately move to fill vacancies on the Constitutional Court in a effort to restore stability after the impeachment of two of his predecessors this month triggered political turmoil.

Finance Minister Choi became acting leader on Friday after the impeachment of Prime Minister Han Duck-soo, who had been acting president since Dec. 14 when Yoon Suk Yeol was suspended from power after a short-lived attempt to impose martial law on Dec. 3.

Choi said he would appoint two Constitutional Court justices immediately, and a third when ruling and opposition parties can agree on nominating a candidate.
