An opposition-led bill on a special counsel investigation to look into last week’s martial law incident has passed a parliamentary subcommittee.

The bill, approved by the subcommittee of the National Assembly’s Legislation and Judiciary Committee, mandates the appointment of a special prosecutor to look into all allegations surrounding President Yoon Suk Yeol’s December 3 martial law decree.

The Assembly has been excluded from the process of recommending a special prosecutor, with the heads of the National Court Administration, the Korean Bar Association and the Korea Law Professors Association each tasked with recommending a candidate.

The president is mandated to appoint one of the candidates.

The main opposition Democratic Party intends to push for the bill’s passage at a plenary session on Saturday, along with a motion seeking Yoon’s impeachment.

Amid a boycott by the ruling People Power Party, the opposition also pushed a bill through the subcommittee to launch a special counsel investigation into allegations surrounding first lady Kim Keon-hee, the opposition’s fourth such bill after three presidential vetoes.

The opposition party plans to handle the Kim Keon-hee bill during a plenary session on Thursday.
