South Korea's opposition parties filed Wednesday a motion to impeach President Yoon Suk Yeol, accusing him of overreach after he briefly imposed martial law, prompting troops to surround parliament before lawmakers voted to revoke it.
Impeaching Yoon would require the support of two-thirds of parliament for the motion and then the backing of at least six Constitutional Court justices.
The motion submitted Wednesday could be put to a vote as early as Friday, Democratic Party lawmaker Kim Yong-min said.
Yoon’s senior advisers and secretaries offered to resign collectively and his Cabinet members, including Defense Minister Kim Yong Hyun, were also facing calls to step down, as the nation struggled to make sense of what appeared to be a poorly thought-out stunt.
In the capital, tourists and residents walked around, traffic and construction were heard and other than crowds of police holding shields, it seemed like a normal sunny, cold December morning.
On Tuesday night, Yoon abruptly imposed an emergency martial law, vowing to eliminate "anti-state" forces after he struggled to push forward his agenda in the opposition-dominated parliament.
However, his martial law was effective for only about six hours, as the National Assembly voted to overrule the president. The declaration was formally lifted around 4:30 a.m. during a Cabinet meeting.
The liberal opposition Democratic Party, which holds a majority in the 300-seat parliament, said Wednesday that its lawmakers decided to call on Yoon to quit immediately or they would take steps to impeach him.
"President Yoon Suk Yeol’s martial law declaration was a clear violation of the constitution. It didn’t abide by any requirements to declare it," the Democratic Party said in a statement.
"His martial law declaration was originally invalid and a grave violation of the constitution. It was a grave act of rebellion and provides perfect grounds for his impeachment," it added.
Impeaching him would require support from two-thirds of the parliament, or 200 of its 300 members. The Democratic Party and other small opposition parties together have 192 seats.
However, when the parliament rejected Yoon’s martial law declaration in a 190-0 vote, 18 lawmakers from Yoon’s ruling People Power Party cast ballots supporting the rejection, according to officials.
The leader of the People Power Party, Han Dong-hun, who has long ties with Yoon dating to their days as prosecutors, criticized Yoon’s martial law declaration as "unconstitutional."
If Yoon is impeached, he’ll be stripped of his constitutional powers until the Constitutional Court can rule on his fate. Prime Minister Han Duck-soo, the No. 2 position in the South Korean government, would take over his presidential responsibilities.
As calls mounted for Yoon’s Cabinet to resign, Han issued a public message pleading for patience and calling for Cabinet members to "fulfill your duties even after this moment."
Yoon’s martial law declaration, the first of its kind in more than 40 years, harkened to South Korea’s past military-backed governments when authorities occasionally proclaimed martial law and other decrees that allowed them to station combat soldiers, tanks and armored vehicles on streets or at public places like schools to prevent anti-government demonstrations. Such scenes of military intervention had not been seen since South Korea achieved a genuine democracy in the late 1980s until Tuesday night.
After Yoon’s declaration, troops carrying full battle gear, including assault rifles, tried to keep protesters away from the National Assembly as military helicopters flew overhead and landed nearby. One soldier pointed his assault rifle at a woman who was among protesters outside the building demanding that the martial law be lifted.
No major violence
It wasn’t clear how the 190 lawmakers were able to enter a parliamentary hall to vote down Yoon’s martial law decree. Opposition leader Lee Jae-myung livestreamed himself climbing over the wall, and while troops and police officers blocked some from entering they didn’t aggressively restrain or use force against others.
No major violence has been reported. The troops and police personnel were later seen leaving the grounds of the National Assembly after the parliamentary vote to lift the martial law. National Assembly Speaker Woo Won Shik said: "Even with our unfortunate memories of military coups, our citizens have surely observed the events of today and saw the maturity of our military."
Han, the People Power Party leader, demanded that Yoon explain his decision and fire Defense Minister Kim Yong Hyun, who he said recommended the martial law decree to Yoon. The Defense Ministry has not commented.
Under South Korea’s constitution, the president can declare martial law during "wartime, war-like situations or other comparable national emergency states" that require the use of military force to restrict the freedom of press, assembly and other rights to maintain order. Many observers question whether South Korea is currently in such a state.
The constitution also states that the president must oblige when the National Assembly demands the lifting of martial law with a majority vote.
Some experts say Yoon clearly violated the constitution in how he imposed martial law. While martial law allows "special measures" to restrict individual freedoms and the authority of agencies and courts, the constitution does not permit the functions of parliament to be restricted. But in following Yoon’s declaration on Tuesday, South Korea’s military proclaimed parliamentary activities were suspended and deployed troops to try to block lawmakers from entering the National Assembly.
Park Chan-dae, the Democratic Party’s floor leader, called for Yoon to be immediately investigated on charges of rebellion over the way he deployed troops to the parliament. While the president mostly enjoys immunity from prosecution while in office, the protection does not extend to alleged rebellion or treason.
In Washington, the White House said the U.S. was "seriously concerned" by the events in Seoul. A spokesperson for the National Security Council said President Joe Biden’s administration was not notified in advance of the martial law announcement and was in contact with the South Korean government.
Pentagon spokesman Maj. Gen. Pat Ryder said there was no effect on the more than 27,000 U.S. service members based in South Korea.
Tourist Stephen Rowan, from Brisbane, Australia, who was touring Gyeongbokgung Palace, said he was not concerned at all.
"But then again, I don’t understand too much about the political status in Korea," he said. "But I hear they are now calling for the current president’s resignation, so ... apparently there’s going to be a lot of demonstrations. ... I would have been concerned if martial law had stayed enforced."
Yoon’s government and ruling party have been embroiled in an impasse with the Democratic Party over next year’s budget bill and a Democratic Party-led attempt to to impeach three top prosecutors.
During his televised announcement, Yoon also described the opposition as "shameless pro-North Korean anti-state forces who are plundering the freedom and happiness of our citizens." He did not elaborate. North Korea had no immediate comments.
Natalia Slavney, research analyst at the Stimson Center’s 38 North website that focuses on Korean affairs, said Yoon’s imposition of martial law was "a serious backslide of democracy" that followed a "worrying trend of abuse" since he took office in 2022.
South Korea "has a robust history of political pluralism and is no stranger to mass protests and swift impeachments," Slavney said, citing the example of former President Park Geun-hye, who was ousted from office and imprisoned for bribery and other crimes in 2017. She was later pardoned.
