On 10 April 2024 the Democratic Party and allies won a commanding National Assembly majority while Lee Jae-myung was party leader in opposition to President Yoon.

Context

The Busan stabbing sat as parent weather. Neighbouring martial-law 2024 is a later civic shock Yoon authored. He did not sit as NEC. An Assembly majority is still ordinary legislative contest.

Stabbing 2 January 2024 is a parent. Martial-law 3 December 2024 is a later neighbour Yoon authored. The 2025 presidency is a child after Yoon’s removal.

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 opposition-leader legislative majority that later constrained Yoon.

What the sources establish

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

Established: 10 April 2024 DP-led Assembly majority under Lee as party leader, independently reported.

Not established: that the presidency was thereby already his, or a unique later martial-law authorship coefficient.

Voters chose. NEC certified. Yoon remained president until 2025.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies The Democratic Party under Lee wins the 2024 National Assembly election, not a later speech about The Democratic Party under Lee wins the 2024 National Assembly election.

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 He led the DP. Voters chose. NEC certified. Yoon remained president until 2025. That limit is the alternative to treating office-holding as authorship of every later series.
