As part of the court case, Alexander vs. South Carolina State Conference of the NAACP, the NAACP challenged the legality of the legislative districts enacted by the South Carolina state legislature for the 2022 South Carolina House of Representatives Election by calling the enacted legislative map a racial gerrymander in violation of the Equal Protection Clause of the 14th Amendment. In order to settle the state legislative portion of the case, both parties agreed to a settlement map which was used for the first time in the 2024 South Carolina House of Representatives Election.
