The opposition-led National Assembly unilaterally passed a special bill on Thursday to investigate suspicions that the Yoon Suk Yeol administration abused its power to interfere with a probe into the death of a young Marine last year. The bill, which garnered approval from 168 out of 296 members of the National Assembly, aims to look into allegations that the Yoon administration pressured an investigator to drop charges against a division commander in the case of Marine Cpl. Chae Su-geun's death during a search and rescue operation. The ruling People Power Party lawmakers, except one, boycotted the vote, dampening the recent spirit of reconciliation between President Yoon and the opposition parties. Both the presidential office and the ruling party criticized the opposition's move, denouncing it as a political maneuver. In a rare moment of bipartisan cooperation during the same plenary session, the rival parties also passed a revised version of a special investigation bill related to the Itaewon crowd crush disaster. The new bill, supported by 256 out of 259 participating Assembly members, establishes an independent investigation panel to look into the tragedy that claimed 159 lives. This revised bill reflects concessions made by both parties, including the omission of clauses granting the panel access to classified legal documents and a reduction in the panel's size from 11 to 9 members. The panel's term, initially set at one year with a possible extension of three months, also underwent changes from the previous version. These developments follow the first official meeting between President Yoon and the main opposition leader Lee Jae-myung, indicating potential shifts in the dynamics between the ruling and opposition parties.
