The decision could touch off a scramble by Republicans to redraw majority-minority congressional districts, especially in the South, that could cost many Black Democrats their seats.

The Supreme Court on Wednesday sharply weakened a key provision of the landmark Voting Rights Act, a ruling that limits the consideration of race in drawing voting maps and could usher in Republican gains in the House.

The decision is expected to touch off a scramble by Republicans to redraw majority-minority districts, especially in the South. New districts could shift the balance of power in Congress by imperiling the reelection prospects of some Black Democrats, possibly as soon as November’s midterms in some instances. Minority representatives in state legislatures and local offices could also be redistricted out.

The court’s conservative majority found Louisiana unlawfully discriminated by race when it created a second majority-Black congressional district to comply with the VRA. But the court did not strike down the provision, known as Section 2, as unconstitutional as many voting rights advocates had feared. Still, the court’s liberal justices and voting rights experts said it was effectively gutted.

The ruling carries significant symbolic weight, scaling back the last major pillar of a 60-year-old law long considered one of the marquee achievements of the civil rights era. The Voting Rights Act bans discriminatory voting practices such as literacy tests and poll taxes, and has helped greatly increase minority representation in state and federal offices.

In an ideologically divided 6-3 ruling, the conservative justices created a higher bar for the law’s powerful provision that allows states to use race to draw maps that help minority communities elect candidates of their choice. Section 2, as it is known, is aimed at combating discriminatory gerrymandering that weakens the power of Black, Latino, Native American and Asian voters.

States must walk a careful line when drawing maps for voting districts. The Voting Rights Act directs states to consider race to some degree when redistricting to ensure that racial minority groups have an opportunity to elect representatives who reflect their priorities. Maps explicitly drawn along racial lines, however, violate the equal-protection clause of the 14th Amendment and the 15th Amendment’s ban on racial discrimination in voting practices.

Justice Samuel A. Alito Jr. wrote the opinion for the majority, saying it was time to rework Section 2 given gains in ending racial discrimination, the use of VRA lawsuits for partisan purposes, and advances in technology that have made it easier to draw legislative districts that balance partisan interests and racial balance.

Alito wrote that going forward, plaintiffs would have to show that a state intentionally discriminated against a minority group in drawing a map, rather than simply showing the minority group did not have the opportunity to elect a candidate of their choice when certain circumstances are met.

“Section 2 of the Voting Rights Act … was designed to enforce the Constitution — not collide with it,” he wrote. “Unfortunately, lower courts have sometimes applied this Court’s [Section] 2 precedents in a way that forces States to engage in the very race-based discrimination that the Constitution forbids.”

The decision came over the sharp objections of the court’s three liberals. Justice Elena Kagan delivered the dissent from the bench, signaling strong disagreement. In her opinion, Kagan lamented that in rulings over the last decade, the court’s conservative justices had carried out a “demolition” of the VRA that was now complete. She predicted a precipitous decline in minority representation in political office.

“The consequences are likely to be far-reaching and grave. Today’s decision renders Section 2 all but a dead letter. In the States where that law continues to matter — the States still marked by residential segregation and racially polarized voting — minority voters can now be cracked out of the electoral process,” Kagan said, referring to the process of drawing maps that break up minority voting blocks.

The decision continues a trend by the court’s conservative majority to roll back race-conscious efforts to redress discriminatory practices. It comes two years after another major decision to restrict race-based affirmative action in college admissions.

The ruling lands as a nationwide redistricting war has broken out between Republicans and Democrats, both of which have taken the unusual step of redrawing district lines between censuses to try to secure partisan advantages in this year’s races for Congress. Republicans currently hold a slim majority.

Professor Richard L. Hasen, an election law expert at UCLA, said Section 2 of the Voting Rights Act still stands but is all but eviscerated.

“The opinion weakens application of the Voting Rights Act to make it a much weaker, and potentially toothless, law,” Hasen wrote on his blog. “It is hard to overstate how much this weakens the Voting Rights Act.”

NAACP President Derrick Johnson said in a statement the ruling is a major strike to minority political power.

“Today’s decision is a devastating blow to what remains of the Voting Rights Act, and a license for corrupt politicians who want to rig the system by silencing entire communities,” Johnson said. “The Supreme Court betrayed Black voters, they betrayed America, and they betrayed our democracy. This ruling is a major setback for our nation and threatens to erode the hard-won victories we’ve fought, bled, and died for.”

Louisiana Attorney General Liz Murrill called the ruling “seismic” in a statement.

“The Supreme Court has ended Louisiana’s long-running nightmare of federal courts coercing the state to draw a racially discriminatory map,” Murrill said.

The complicated dispute over the Louisiana voting district has dragged on for years and had been before the court last term.

The case began in 2022 when Black voters and civil rights groups sued Louisiana under Section 2, saying a new voting map drafted after the 2020 Census shortchanged African American voters. The map had only one Black-majority district out of six. African Americans make up one-third of the state’s population.

A federal court ruled for the plaintiffs and ordered the state to draw a new map with a second Black-majority district. After further legal wrangling, the Louisiana legislature drafted one in 2024.

The new map, which was drawn in part to protect the seats of Republican incumbents, including House Speaker Mike Johnson and House Majority Leader Steve Scalise, created a Black-majority district that meandered across the state from Baton Rouge to Shreveport.

A group of self-described “non-Black voter[s]” sued, arguing the new map was an unconstitutional racial gerrymander that violated the equal protection clause. A federal district court panel ruled for the non-Black plaintiffs and put a hold on the redrawn map.

The Supreme Court eventually allowed the map with two Black-majority districts to go into effect for the 2024 congressional election. Voters chose Cleo Fields, a Black Democrat, for the new district.

The non-Black voters brought their case to the Supreme Court once again. Last term, the justices decided to hold off on a ruling and asked both sides to address whether creation of the second Black-majority district violated the 14th and 15th Amendments, before taking up the case again this term.

During arguments in October, Louisiana Solicitor General Benjamin Aguiñaga told the justices that any “race-based redistricting is fundamentally contradictory to our Constitution.” He also said that Louisiana had changed in recent decades, so the need for Section 2 had been obviated.

“It requires striking enough members of the majority race to sufficiently diminish their voting strength, and it requires drawing in enough members of a minority race to sufficiently augment their voting strength,” Aguiñaga said. “Embedded within these express targets are racial stereotypes that this court has long criticized.”

Kagan asked an attorney for Black voters in Louisiana what impact gutting Section 2 would have.

“The results would be pretty catastrophic,” said Janai Nelson, the president of the NAACP Legal Defense Fund.

“We only have the diversity we see across the South because of litigation” under the voting rights law, Nelson said, adding that it had been “crucial to diversifying leadership” in Louisiana and other states. She said no Black person has been elected to statewide office in Louisiana to date.

The decision follows another by the Supreme Court involving Section 2 in 2023. In that case, the justices ruled Alabama created electoral maps that unlawfully diluted the power of Black residents. That ruling surprised many court watchers because the justices have chipped away at the VRA in recent years.

In the most significant ruling in 2013, the justices struck down Section 5 of the VRA, which required states with a history of discriminating against minority voters to get changes to electoral law approved by the federal government or a judge. Most of the states covered by the provision are in the South.

The latest ruling is likely to contribute to the uncertainty surrounding the nation’s electoral maps, amid the unprecedented wave of mid-decade redistricting. Ordinarily, states redraw their lines at the beginning of each decade after the U.S. Census Bureau alerts states to population shifts.

President Donald Trump, concerned Republicans could lose their fragile House majority, began pressing Republican-led states last summer to draw new lines ahead of the midterm elections. Republicans drew better lines for themselves in Ohio, Missouri, North Carolina and Texas that could give them strong shots at picking up nine more seats.

Florida Republicans are planning to carve up their districts to give their party up to four more districts, and were debating their plan on the floor of the state House when the court released its decision.

In response, voters in California approved a new map that will give Democrats up to five more House seats, and voters in Virginia approved a plan to redraw their map. The Supreme Court turned aside a challenge to the California map in February.

The Supreme Court’s decision probably gives Republicans an opportunity to draw even more districts in their favor.

The deadlines for most states to redraw their maps before the midterms have passed, but it’s possible some states push to change those rules. Either way, the ruling could set Republicans up for advantages in 2028 and beyond. In the wake of the decision, Sen. Marsha Blackburn (R-Tennessee) called on lawmakers in Tennessee to redraw maps to create an extra Republican seat in Memphis.

This Supreme Court term is shaping up as a consequential one for election-related law.

In one major case, the court will decide the constitutionality of counting mail-in ballots that arrive after an election, provided they are postmarked by Election Day. The justices also allowed a lawsuit by a Republican congressman from Illinois who is challenging the state’s mail-in ballot law.

The justices heard arguments in December over whether to lift restrictions on parties spending money in coordination with candidates, which could be the latest chance for the court to curtail campaign finance limits.
