On January 6, a 3-judge U.S. District Court struck down the South Carolina U.S. House boundaries for the First District as a violation of the Voting Rights Act. South Carolina Conference of the NAACP v Alexander, 3:21cv-3302. Here is the decision. The court asks the legislature to draw new boundaries by March 31, 2023. If the legislature does not do that, presumably the court will appoint a special master to draw new boundaries.
The decision is from Judge Toby Heytens (a Biden appointee), Mary Geiger Lewis (Obama), and Richard M. Gergel (Obama). Thanks to ElectionLawBlog for the link.
