The Supreme Court's conservative majority allowed Alabama to use a congressional map that eliminates a majority-Black district, overriding a lower court ruling that found the plan was "tainted by intentional race-based discrimination." This decision signals a significant shift in how the court will handle redistricting cases, particularly those involving claims of racial discrimination under the Voting Rights Act.

The ruling comes after the justices in April overhauled the legal standard for evaluating redistricting claims, requiring plaintiffs to show evidence that lawmakers intentionally set out to disadvantage people based on race. The decision effectively raises the bar for successful challenges to voting maps, making it harder to prove violations of civil rights laws.

Legal experts note the decision reflects the court's desire to limit federal courts' role in policing redistricting, with critics suggesting the ruling essentially nullifies the Voting Rights Act. The practical effect could be declining racial diversity among elected officials in Southern states where Republican lawmakers target districts held by Black Democrats.
