The National Assembly on Saturday failed to vote on the impeachment of President Yoon Suk Yeol as all but three People Power Party legislators boycotted the vote.

Voting came to a close at 9:20 p.m. with the motion automatically rejected, as the number of lawmakers who cast ballots did not reach the quorum of 200.

Passing a presidential impeachment motion requires the approval of at least two-thirds of all sitting lawmakers, equivalent to 200 votes.

The failed attempt to impeach Yoon came four days after Yoon sparked a political firestorm by declaring emergency martial law late Tuesday night, only to revoke it six hours later under parliamentary pressure.
