The Supreme Court’s recent decision in Louisiana v. Callais marks a major shift in how federal law treats racial gerrymandering. At the center of the ruling is not just the 6–3 majority opinion, but a striking concurrence from Clarence Thomas that signals deep frustration with decades of legal precedent and a desire to go much further than the Court ultimately did.
The case arose from Louisiana’s attempt to redraw its congressional districts after the 2020 census. Initially, the state adopted a map with one majority-Black district. A federal court ruled that map likely violated Section 2 of the Voting Rights Act, which prohibits racial discrimination in voting, and ordered Louisiana to create a second majority-Black district. The state complied, but that new map was challenged by a group of “non-African American” voters who argued it was an unconstitutional racial gerrymander.
A lower court agreed, and the case made its way to the Supreme Court. In a 6–3 decision, the Court upheld the lower court’s ruling and struck down the revised map. Writing for the majority, Samuel Alito concluded that Louisiana had “no compelling interest” in using race to draw the district. While acknowledging that the Voting Rights Act sometimes intersects with redistricting, the Court made clear that race-based map drawing must meet strict constitutional scrutiny and, in this case, did not.
The majority did not eliminate Section 2’s role in redistricting altogether. Instead, it narrowed its application and raised the bar for proving violations. The Court emphasized that claims of racial vote dilution must be carefully distinguished from partisan politics, noting that “a litigant can easily exploit §2 for partisan purposes by repackaging a partisan-gerrymandering claim as a racial-gerrymandering claim.”
That alone would have made the decision significant. But Thomas went further.
In a separate concurrence joined by Neil Gorsuch, Thomas made clear that he believes the Court did not go far enough. “I would go further and hold that §2 of the Voting Rights Act does not regulate districting at all,” he wrote. This was not a new position for him, but the clarity and force of the statement stood out.
Thomas argued that the entire framework of “vote dilution” is built on a misreading of the law. According to him, Section 2 was always intended to address access to voting, such as literacy tests or poll taxes, not how districts are drawn. “The most natural reading of this text is that it addresses barriers to voting… not the drawing of legislative districts,” he wrote.
He went even further in criticizing the Court’s past decisions, particularly those stemming from Thornburg v. Gingles. Those rulings established the legal tests used to evaluate whether district maps dilute minority voting power. Thomas dismissed that entire body of law as lacking any foundation in the statute itself. “The concept of vote dilution is a judicial invention,” he wrote, arguing that it has transformed the Voting Rights Act into something Congress never intended.
What appears to drive Thomas most strongly is a constitutional concern. He argues that the current system effectively forces states to sort voters by race in order to comply with federal law. That, he says, runs directly into the Equal Protection Clause. “The Constitution does not require States to sort voters by race,” he wrote, adding that it is doubtful the Constitution even permits it.
This is where Thomas’s tone becomes especially revealing. He quoted his own earlier writing from 1994, calling the Court’s approach to voting rights a “disastrous misadventure.” That kind of language is rare for a justice known for consistency and restraint. It suggests not just a legal disagreement, but a long-standing frustration that has only grown over time.
If Thomas’s view were to become the majority position, the consequences would be sweeping. Section 2 of the Voting Rights Act would no longer apply to redistricting cases at all. Federal courts would largely step out of the business of evaluating district maps for racial fairness. Challenges to gerrymandering would have to rely on constitutional claims alone, which are significantly harder to prove.
Critics of the decision, particularly the dissenting justices, see this as a dangerous shift. In a sharply worded dissent, Elena Kagan warned that the ruling “renders Section 2 all but dead letter.” She argued that the new legal standards make it nearly impossible for plaintiffs to succeed in vote dilution cases, effectively stripping away a key protection for minority voters.
Kagan emphasized that the Voting Rights Act was one of the most important civil rights laws in American history and that only Congress should decide whether its protections are still needed. “Only Congress can say it is no longer needed,” she wrote, rejecting the majority’s reinterpretation of the law.
The divide between the majority and the dissent reflects a broader philosophical clash about the role of the courts. On one side is a view that federal courts must actively guard against subtle forms of racial discrimination in voting. On the other is Thomas’s view that the courts have overstepped, inserting themselves into inherently political decisions and distorting the law in the process.
What makes this moment stand out is how far Thomas was willing to go in saying so. He did not simply agree with the majority. He used the opportunity to argue for dismantling a major pillar of voting rights jurisprudence altogether. For a justice who has held this position for decades, the concurrence reads less like a new idea and more like a final, emphatic warning.
Whether the Court eventually follows him remains to be seen. But after this decision, it is clear that the debate over gerrymandering and the Voting Rights Act is far from settled.
