A motion to impeach President Yoon Suk Yeol has been reported to a plenary session of the National Assembly.

The motion, proposed by 190 opposition party lawmakers and one independent lawmaker, was reported at 12:48 a.m. Thursday.

The ruling People Power Party, which decided to oppose Yoon’s impeachment, did not attend the session. 

In proposing the motion to parliament, opposition lawmakers said that in declaring martial law, Yoon violated the Constitution and other laws concerning the principles of popular sovereignty and the separation of powers.

They also said his martial law decree infringed on freedom of expression, as it put all media and publishing outlets under the control of the martial law command and banned strikes and protests.

A vote on the motion is likely to take place as early as Friday, or Saturday at the latest, as the law stipulates that a vote must occur between 24 hours and 72 hours after a motion is reported to the plenary session.
