SEOUL - South Korea's parliament on Wednesday reported an impeachment motion against former acting President Choi Sang-mok, deputy prime minister for economic affairs, over his refusal to appoint a justice of the constitutional court during his acting presidency.

The motion to impeach Choi was reported during the National Assembly's plenary session after the main opposition Democratic Party and four other minor parties submitted it on March 21.

Following the impeachment of both President Yoon Suk-yeol and Prime Minister Han Duck-soo last December, Choi had served as acting president for about three months until March 24 after Han was reinstated as prime minister and acting president.

The impeachment motion against Choi was submitted for four reasons, including Choi's alleged involvement in the impeached President Yoon's botched martial law imposition and his refusal to appoint a constitutional court justice.

The nine-member constitutional court currently has eight justices as one has yet to be appointed by the acting president.

The constitutional court planned to decide whether to remove Yoon from office on Friday.

Yoon declared an emergency martial law on the night of Dec 3 last year, but it was revoked by the opposition-led National Assembly hours later.
