The National Assembly, led by the opposition, approved a controversial bill on Thursday that requires a special counsel to investigate the Yoon Suk Yeol administration and the military's handling of a young Marine's death last year. Out of 190 participating lawmakers, 189 voted in favor of the bill, while one opposed it. The ruling People Power Party, with the exception of two members, boycotted the vote by leaving before the plenary session. The bill, which demands the establishment of a special counsel to examine allegations of interference by high-ranking Defense Ministry officials and the presidential office in an internal military inquiry into the death of Cpl. Chae Su-geun, was introduced the day before. The opposition's move came after over 180 lawmakers voted to end the ruling party's filibuster, which had lasted for more than 24 hours. As a result of the bill's passage, the opening ceremony for the 22nd parliament, initially scheduled for Friday, has been indefinitely postponed.
