On 3 June 2025 South Korea held a snap presidential election after Yoon’s removal. NEC certified Lee Jae-myung of the Democratic Party with 49.42 percent (about 17.29 million votes) against Kim Moon-soo’s 41.15 percent; turnout was about 79.4 percent, the highest presidential turnout since 1997.

Context

Constitutional Court removal of Yoon on 4 April 2025 sat as parent. Neighbouring 4 June oath is a child. He did not sit as NEC. A snap win is still ordinary democratic succession after a vacancy.

Martial-law 3 December 2024 is a parent civic shock Yoon authored. Inauguration 4 June is a child. Article 84 stay is a neighbouring legal child, not this ballot.

The President of the Republic of Korea is head of state and of the executive, appoints the prime minister with National Assembly consent, and commands the armed forces. The National Assembly enacts statutes. The Bank of Korea sets the policy rate. Courts, including the Supreme Court and Constitutional Court, judge. Chaebol boards, US Forces Korea, and provincial governments share later series. A Seongnam mayoral youth dividend or debt moratorium is not a 2025 statute. A criminal case must be stored with exact charge and judgment status — an allegation, indictment, first-instance finding, appellate acquittal, Supreme Court remand, or Article 84 stay is not a completed conviction if appealed, overturned, or pending. He did not author Yoon Suk Yeol’s 3 December 2024 martial-law decree.

Why it matters

The path is democratic resilience: a completed high-turnout snap rotation after an impeachment vacancy.

Evidence

The sources behind this fact and its verification state.

Verified2 sources on file

  2. 2.Lee Jae-myung elected President in the 21st Presidential ElectionNational Election Commission of South Korea · High credibility · verified
What the sources establish

National Election Commission of South Korea carries the official instrument or communique. Reuters records the same dated act independently.

Established: 3 June 2025 NEC 49.42 percent certification, independently reported.

Not established: a unique later CPI coefficient from that Tuesday, or that the remanded election-law file was thereby erased.

He was the candidate. Voters chose. Kim Moon-soo conceded. Yoon’s removal was the parent vacancy.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies NEC certifies Lee winner of the 21st presidential election with 49.42 percent, not a later speech about NEC certifies Lee winner of the 21st presidential election with 49.42 percent.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to NEC certified. He was the candidate. Voters chose. Kim Moon-soo conceded. Yoon’s removal was the parent vacancy. That limit is the alternative to treating office-holding as authorship of every later series.
