South Korea’s opposition-controlled National Assembly voted Friday to impeach acting President Han Duck-soo despite vehement protests by governing party lawmakers, further deepening the country’s political crisis set off by President Yoon Suk Yeol’s stunning imposition of martial law and ensuing impeachment.

Han’s impeachment means he will be stripped of the powers and duties of the president until the Constitutional Court decides whether to dismiss or reinstate him. The court is already reviewing whether to uphold Yoon's earlier impeachment. The impeachments of the country’s top two officials has worsened its political turmoil, deepened economic uncertainties and hurt its international image.

The single-chamber National Assembly passed Han’s impeachment motion with a 192-0 vote. Lawmakers with the governing People Power Party boycotted the vote and surrounded the podium where assembly Speaker Woo Won Shik was seated, shouting that the vote was "invalid" and demanding Woo's resignation. No violence or injuries were reported.

The PPP lawmakers protested after Woo called for a vote on Han’s impeachment motion after announcing its passage required a simple majority in the 300-member assembly, not a two-thirds majority as claimed by the PPP. Most South Korean officials can be impeached by the National Assembly with a simple majority vote, but a president’s impeachment needs the support of two-thirds. There are no specific laws on the impeachment of an acting president.

In a statement, Han called his impeachment "regrettable" but said he respects the assembly's decision and will suspend his duties to "not add to additional confusion and uncertainty." He said he will wait for "a swift, wise decision" by the Constitutional Court.

Han’s powers were officially suspended after copies of his impeachment document were delivered to him and the Constitutional Court. The deputy prime minister and finance minister, Choi Sang-mok, took over.

Later Friday, Choi's office said he instructed the military to boost its readiness to help prevent North Korea from miscalculating the situation and launching provocations. He also told the foreign ministry to inform the U.S., Japan and other major partners that South Korea's foreign policies remain unchanged.

Han, who was appointed prime minister by Yoon, became acting president after Yoon, a conservative, was impeached by the National Assembly about two weeks ago over his short-lived Dec. 3 imposition of martial law. Han quickly clashed with the main liberal opposition Democratic Party as he pushed back against opposition-led efforts to fill three vacant seats on the Constitutional Court, establish an independent investigation into Yoon’s martial law decree and legislate pro-farmer bills.

At the heart of the fighting is the Democratic Party’s demand that Han approve the assembly's nominations of three new Constitutional Court justices to restore its full nine-member bench ahead of its ruling on Yoon’s impeachment. That’s a politically sensitive issue because a court decision to dismiss Yoon as president needs support from at least six justices, and adding more justices will likely increase the prospects for Yoon’s ouster. Yoon’s political allies in the governing party oppose the appointment of the three justices, saying Han shouldn’t exercise the presidential authority to make the appointments while Yoon has yet to be formally removed from office.

On Thursday, Han said he wouldn’t appoint the justices without bipartisan consent. Later in the day, the Democratic Party, which holds a majority in the assembly, submitted an impeachment motion against Han and passed bills calling for the appointment of three justices.

South Korean investigative agencies are probing whether Yoon committed rebellion and abuse of power with his marital law decree. Yoon has repeatedly ignored requests by authorities to appear for face-to-face questioning,

His defense minister, police chief and several other senior military commanders have already been arrested over the deployment of troops and police officers to the National Assembly, which prompted a dramatic standoff that ended when lawmakers managed to enter the chamber and voted unanimously to overrule Yoon’s decree.

South Korean media reported that prosecutors indicted former Defense Minister Kim Yong Hyun for allegedly playing a key role in Yoon's rebellion plot and committing abuse of power and obstruction. The reports said Kim, a close associate of Yoon, became the first person to be formally charged over the martial law decree. Calls to a Seoul prosecutors' office were unanswered.

Han's impeachment motion accuses him of collaborating and abetting Yoon's declaration of martial law. It also accuses Han of attempting to obstruct the restoration of the Constructional Court's full membership and of delaying investigations into Yoon's alleged rebellion by not appointing independent counsels.

The martial law enactment, the first of its kind in more than 40 years in South Korea, lasted only six hours but it caused political turmoil in South Korea, triggered alarms from its neighbors and rattled markets. Yoon has defended his decree as an act of governance, saying it was a warning to the Democratic Party which he said has been using its parliamentary majority to obstruct his agenda.
