US Supreme Court Decision Weakens Voting Rights Act, Sparks Southern Redistricting Battles

On April 29, the U.S. Supreme Court ruled in Louisiana v. Callais that Louisiana’s congressional map containing two majority‑Black districts violated the Constitution, effectively striking down the portion of Section 2 of the Voting Rights Act that safeguards against vote‑dilution. The decision raises the burden for challengers, requiring proof of intentional discrimination rather than showing discriminatory effects.

Civil‑rights groups warn that the ruling makes it harder to contest future district maps and could diminish the voting power of Black, Latino and AAPI communities across the South. Lawmakers in several Southern states have already begun discussing emergency redistricting sessions. Mitchell Brown of the Southern Leadership for Voter Engagement Network said, “It makes it harder to challenge maps … and … harder for voters of color to let their voices be heard in our communities.” Some political scholars also argue that expanding the size of Congress could improve minority representation as an additional remedy.
