Despite receiving an invitation from the Democratic Party, the Green Justice Party declined to participate in the electoral alliance due to their stance against the formation of satellite parties.[4]
Lee Sang-heon, the MP for Buk, Ulsan, announced his withdrawal from the Democratic Party following the Democratic Alliance's decision to support for Yoon Jong-oh, a member of the Progressive Party as well as the former MP for the constituency.[14][15][16]
On 14 February 2024, the Democratic Alliance rejected the nomination of Lim Tae-hoon, former chair and founder of the Military Human Rights Commission, for a spot on the proportional representation list. The reason given by the Democratic Party was that Lim had been arrested in the early 2000s for evading military conscription, which is required by law for all men in South Korea. Lim, who is openly gay, would also have been the Democratic Party's first sexual minority in a national election. Some members of the Democratic Party hold social conservative opinions.[17] The Democratic Party also rejected an appeal from Lim, despite conscientious objection being legalized in 2018. Lim was pardoned by President Roh in 2005 and thus founded the Military Human Rights Commission in 2009.
Hours after the announcement of the rejection of candidate Lim, the civil society and human rights groups within the electoral alliance threatened to withdraw their support and candidates from the electoral alliance on 14 February 2024.[18]
