Challengers to Alabama’s latest redistricting push urged the Supreme Court on Monday not to let the state use a congressional map in this fall’s elections that a lower court found likely discriminated against Black voters.

The groups, including voters and Democratic officials in the state, argued the justices should keep the state’s congressional lines used in the 2024 elections. That map was implemented by a three-judge court after it found the state’s first two congressional maps likely discriminated against Black voters.

Last week, the same three-judge court blocked a legislature-approved map Alabama officials want to use in this fall’s elections, known as the 2023 plan, finding it still violated the Constitution. State officials asked the Supreme Court to allow them to use the 2023 plan.

Monday’s filings come amid fast-moving litigation following a Supreme Court decision tossing out a Louisiana congressional map that prompted Alabama and other Southern states to redraw their districts.

One filing from a group of voters in the state, led by Marcus Caster, argued that Alabama has for years attempted to draw congressional maps that discriminate against Black voters. The filing argued that didn’t change because of the Supreme Court’s decision in an unrelated case that tossed out a Louisiana congressional map with two minority opportunity districts.

The Supreme Court’s Louisiana decision “did not invite legislatures to immunize discriminatory maps by concocting pretextual and inviolable criteria that lock in an illegitimate scheme,” the filing said.

A filing from Democratic state Sen. Bobby Singleton and voters in the state said Alabama officials sought now to implement a congressional plan that would undermine the power of Black voters.

“Entering a stay so that Alabama can at the last minute replace a lawful plan with an unlawful and unconstitutional one would create chaos and would reward Applicants for their repeated false statements to this Court,” the response said.

The Singleton filing also pointed out that state officials had already said it would be “impossible” to implement the 2023 plan map as late as this week.

“Now May 27 has passed; instead of a week, there are only hours to reassign voters. Accordingly, the evidence in the record shows that Alabama cannot administer its special primary election under the 2023 Plan, even with a stay entered today, June 1,” the filing said.

The National Republican Congressional Committee weighed in as well in its own filing siding with Alabama, emphasizing the impact the lower-court ruling would have on ongoing campaigns. The brief argued the court-ordered map used in 2024 amounted to “court-ordered racial gerrymandering.”

Separately, the Trump administration filed a brief urging the justices to side with Alabama.

The state held a primary in the unchanged districts on May 19. Republican Gov. Kay Ivey announced an August primary for where the lines would change under the 2023 plan.
