SEOUL, South Korea — South Korea’s parliament impeached President Yoon Suk Yeol on Saturday over his stunning and short-lived martial law decree, a move that ended days of political paralysis but set up an intense debate over Yoon’s fate, as jubilant crowds roared to celebrate another defiant moment in the country’s resilient democracy.

The National Assembly passed the motion 204-85.

Yoon’s presidential powers and duties were subsequently suspended and Prime Minister Han Duck-soo, the country’s No. 2 official, took over presidential powers.

The Constitutional Court has 180 days to determine whether to dismiss Yoon as president or restore his powers. If he’s thrown out of office, a national election to choose his successor must be held within 60 days.

It was the second National Assembly vote on Yoon’s impeachment after ruling party lawmakers boycotted the first floor vote last Saturday. Some People Power Party lawmakers had since said they would vote for Yoon’s impeachment as public protests intensified and his approval rating plummeted.

National Assembly Speaker Woo Won Shik said 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 as a lead activist shouted on stage, “We have preserved the constitutional order!”

In a central Seoul plaza, another huge crowd supporting Yoon grew subdued after hearing he had been impeached.

Yoon issued a statement saying he would “never give up” and calling for officials to maintain stability in government functions during what he described as a “temporary” pause of his presidency.

“I will carry with me all the criticisms, encouragement and support directed toward me, and I will continue to do my utmost for the country until the very last moment,” Yoon said.

Yoon’s Dec. 3 imposition of martial law, 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. Yoon was forced to lift his decree after parliament unanimously voted to overturn it.

Han, the acting leader, ordered the military to bolster its security posture to prevent North Korea from launching provocations by miscalculation. Han asked the foreign minister to inform other countries that South Korea’s major external policies remain unchanged, and the finance minister to work to minimize potential negative impacts on the economy by the political turmoil, according to Han’s office.

“I earnestly ask public servants this. At this moment, we have the critical task of ensuring normal and stable operations of state affairs ... I ask you to carry out your duties without any neglect to ensure that the government is operated without being shaken,” Han said in a televised statement.

South Korea’s executive power is concentrated with the president, but the prime minister leads the country if the president becomes incapacitated. Han is a seasoned official and has previously held a string of top government posts such as trade minister and finance minister. He also served as a prime minister from 2007-2008.

After declaring martial law, 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 Yoon’s decree. No major violence occurred.

Opposition parties accuse Yoon of rebellion, citing a law that categorizes as rebellion the staging of a riot against established state authorities to undermine the constitution. They also say that a president in South Korea is allowed to declare martial law only during wartime or similar emergencies and has no right to suspend parliament’s operations even under martial law.

The impeachment motion alleged that Yoon “committed rebellion that hurt peace in the Republic of Korea by staging a series of riots.” It said 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 Thursday, Yoon rejected the rebellion charges, calling his martial law introduction an act of governance. The conservative Yoon said he aimed to issue a warning to the main liberal opposition Democratic Party, calling it “a monster” harboring “anti- state forces” that he argued has flexed its legislative muscle to impeach many top officials and undermine the government’s budget bill for next year. He claimed the troop deployment was meant to maintain order rather than disrupt it.

Observers say Yoon’s speech suggested a focus on legal preparations to defend his martial law decree at the Constitutional Court, even as opinion surveys showed more than 70% of South Koreans supported his impeachment. A survey released Friday put Yoon’s approval rating at 11%, the lowest since he took office in 2022.

Yoon has been banned from leaving South Korea. Yoon’s defense minister and police chief and two other high-level figures have been arrested over the martial law enforcement.

He has the presidential privilege of immunity from criminal prosecution but that doesn’t extend to allegations of rebellion or treason. But observers doubt that authorities will forcefully detain him because of the potential for clashes with his presidential security service.
