A three-judge panel has struck down Alabama’s congressional map on Tuesday, after GOP state lawmakers refused a court mandate to draw a second majority-Black district.

The federal judges wrote that they were “deeply troubled” that the state legislature declined to draw two majority Black districts. The same court ruled last year that it should draw a second majority-Black district to comply with the Voting Rights Act. The Supreme Court affirmed the ruling from the lower court earlier this year.

An independent court-appointed expert will now draw Alabama’s congressional map for the 2024 election. Republicans in the state are expected to appeal the decision, which could eventually make its way to the Supreme Court again.
