The Supreme Court’s landmark decision in Louisiana v. Callais may dramatically alter congressional districts in Southern states. Writing for a 6-3 majority, Justice Samuel Alito unraveled decades of confusing and misguided caselaw construing the 1965 Voting Rights Act (VRA) to hold that states may not engage in racial gerrymandering—or be forced to do so by federal courts—when drawing congressional districts. The Constitution’s Equal Protection Clause forbids race-based discrimination, Alito pointedly declared, preventing Section 2 of the VRA from being interpreted to require the creation of “majority-black” districts to comply with the VRA.
