Supreme Court narrows Voting Rights Act path for race-conscious redistricting

The Supreme Court’s 6-3 decision in Louisiana v. Callais significantly narrows how section 2 of the Voting Rights Act can be used to defend race-conscious redistricting, adding new uncertainty to congressional mapmaking ahead of the midterms, reports Politico.

Writing for the conservative majority, Justice Samuel Alito concluded that Louisiana was not required by the Voting Rights Act to create a second majority-Black congressional district. Because that legal obligation was absent, he wrote, the state lacked the compelling interest needed to justify using race so directly in its map. The Court held that prior evidence must support a “strong inference” of racial discrimination before race-conscious remedies may be justified.

The ruling does not formally strike down section 2, but it changes the practical terrain. Since Congress amended the Voting Rights Act in 1982, plaintiffs have been able to challenge election rules and maps based on discriminatory effects, not only provable discriminatory intent. That amendment responded to the reality that public officials rarely admit racial motives. The Court’s leading Section 2 framework, Thornburg v. Gingles, has long required proof that a minority group is large and compact enough to form a district, politically cohesive, and usually defeated by bloc voting from the majority.

Alito’s opinion reflects the Court’s continuing effort to separate racial discrimination claims from partisan gerrymandering claims. That distinction became more important after Rucho v. Common Cause, when the Court held that partisan-gerrymandering disputes are generally beyond the reach of federal courts. Alito warned that plaintiffs could repackage partisan disputes as racial vote-dilution claims.

Justice Elena Kagan, joined by the Court’s two other liberal justices, said the majority had effectively gutted Congress’ 1982 amendment. In her view, the decision permits states to dilute minority voting strength while avoiding liability unless challengers meet a newly demanding evidentiary threshold.

The decision continues a broader Roberts Court trend of limiting federal voting-rights protections after Shelby County v. Holder weakened preclearance and Brnovich v. Democratic National Committee narrowed challenges to voting rules. For states, the ruling may reduce legal pressure to draw majority-minority districts. For voters, it means Section 2 remains alive—but harder to enforce.
