Alabama cannot use a new Republican-friendly map in this year’s midterm elections because it was drawn to intentionally discriminate against Black voters, a panel of three federal judges ruled on Tuesday.

The decision blocks Alabama from using a congressional map lawmakers passed in 2023 but never went into effect because the same court found it was drawn with intent to discriminate. Alabama was eventually ordered to adopt a map with two majority-Black districts that both elected Democrats. After the US supreme court gutted a major provision of the Voting Rights Act in a case called Louisiana v Callais in April, Alabama took the extraordinary step of moving its imminent congressional primary and sought to use the 2023 congressional map this year.

The state will probably appeal to the US supreme court.
