Acting President Choi Sang-mok's appointment of two Constitutional Court justices, along with his veto of opposition-led special probe bills, further complicated the strategies of the rival parties, political analysts said Wednesday.

The Constitutional Court of Korea, which is tasked with reviewing the impeachment cases of both President Yoon Suk Yeol and acting President and Prime Minister Han Duck-soo, said Monday that a majority of its justices view the National Assembly's impeachment of Han as valid.

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.
