South Korean parliament votes to impeach President Yoon Suk Yeol

South Korea’s parliament has voted to impeach President Yoon Suk Yeol over his short-lived martial law declaration this month.

The National Assembly passed the motion in a 204-85 vote on Saturday.

Mr Yoon’s presidential powers and duties will be suspended after the copies of a document on the impeachment are delivered to him and to the Constitutional Court.

Mr Yoon had previously defended his step as an act of necessary governance and vowed to “fight to the end” in the face of opposition-led efforts to remove him from office.

The court has up to 180 days to determine whether to dismiss Mr Yoon as President or restore his powers.

It was the second National Assembly vote on Mr Yoon’s impeachment motion. Last Saturday, he survived an impeachment vote after most ruling party members boycotted the floor vote.

Some People Power Party legislators had since announced their intentions to vote for Mr Yoon’s impeachment in a second vote, as public protests against the President intensified and his approval rating plummeted.

National Assembly Speaker Woo Won Shik said Mr Yoon’s impeachment was an outcome driven by “the people’s ardent desire for democracy, courage and dedication”.

Hundreds of thousands of people gathered near the parliament roared in jubilation, waved banners and brandished colourful K-pop glow sticks, as a lead activist declared on stage: “We have preserved the constitutional order.”

In a central Seoul plaza, another huge crowd of people supporting Mr Yoon gathered, but they grew subdued after hearing the President had been impeached. Both rallies have largely been peaceful.

Mr Yoon’s martial law imposition, the first of its kind in more than four decades in South Korea, lasted only six hours, but has caused massive political tumult, halted diplomatic activities and rattled financial markets.

After declaring martial law, Mr Yoon sent hundreds of troops and police officers to the parliament to try to impede its vote on the decree before they withdrew after the parliament rejected it. No major violence occurred.

Opposition parties and many experts accuse Mr Yoon of rebellion, citing a law clause that categorises as rebellion the staging of a riot against established state authorities to undermine the constitution.

They also say that by law a president in South Korea is allowed to declare martial law only during wartime or similar emergencies and has no rights to suspend parliament’s operations even under martial law.

The impeachment motion alleged that Mr Yoon “committed rebellion that hurts peace on the Republic of Korea by staging a series of riots”.

It said Mr Yoon’s mobilization of military and police forces threatened the National Assembly and the public and that his martial law decree was aimed at disturbing the Constitution.

In a fiery speech on Thursday, Mr Yoon rejected the rebellion charges, calling his martial law order an act of governance.

“I will fight to the end to prevent the forces and criminal groups that have been responsible for paralysing the country’s government and disrupting the nation’s constitutional order from threatening the future of the Republic of Korea,” Mr Yoon said.

Democratic Party leader Lee Jae-myung called Mr Yoon’s speech a “mad declaration of war” against his own people.

The Democratic Party and five other opposition parties control the 300-member unicameral parliament with a combined 192 seats, but they were eight seats shy of the two-thirds majority needed to pass Mr Yoon’s impeachment motion and needed support from ruling party lawmakers.

The President has been banned from leaving South Korea, as law enforcement authorities are investigating whether he and others involved in the martial law declaration committed rebellion, abuse of power and other crimes.

If convicted, the leader of a rebellion plot can face the death penalty or life imprisonment.

Mr Yoon has the presidential privilege of immunity from criminal prosecution but that does not extend to allegations of rebellion or treason.

Subsequently, Mr Yoon could be investigated, detained, arrested or indicted over his martial law decree, but many observers doubt that authorities will forcefully detain him because of the potential for clashes with his presidential security service.

Mr Yoon’s defence minister, police chief and the head of Seoul’s metropolitan police agency have been arrested over their roles in the martial law case. Other senior military and government officials also face investigations.
