Few powers in American politics are as consequential as redistricting. The Voting Rights Act of 1965 (VRA) has long protected minority voters from racial discrimination in that process, ensuring opportunities to elect candidates of their choice to represent them. Now, one looming Supreme Court case is putting it under threat.

Louisiana v. Callais (2025) began as a challenge to a congressional map that limited Black voters’ power. What started as a state-level dispute has grown into a case that could determine the Voting Rights Act's strength. With the nation already in the midst of aggressive mid-decade redistricting, the Supreme Court’s decision could reshape representation at every level of governance far beyond Louisiana.

What is the Voting Rights Act?

After the Union’s victory in the Civil War, the ratification of constitutional amendments was intended to enshrine African Americans’ civil rights in the highest form of American law. Section 1 of the 14th Amendment, ratified in 1868, guaranteed citizenship to all persons born or naturalized in the United States, and Section 2 required congressional apportionment based on the “whole number of persons in each state,” rectifying the previous three-fifths language that diluted the representation of African Americans. Section 1 of the 15th Amendment, ratified in 1870, prohibited the denial of voting rights based on “race, color, or previous condition of servitude,” extending the franchise to Black men.

Federal troops stationed in the South during Reconstruction upheld Black men’s ability to vote; however, once Reconstruction ended, the 14th and 15th amendments ceased to have any practical effect. Southern states used loopholes in the 15th Amendment to implement “Jim Crow” laws, a range of measures aimed at disenfranchising Black voters without explicitly characterizing them on the basis of race. One such method was the misuse of grandfather clauses, which made men eligible to vote only if they had been able to vote before African-Americans were enfranchised, or if they were the lineal descendants of those voters. Eleven states in the South had a law requiring citizens to pay a poll tax before they could vote, disproportionately impacting Black voters who were largely impoverished after generations of slavery. The literacy test was one of the most insidious methods of suppressing the Black vote, requiring prospective voters to answer a series of questions at the discretion of the voting clerks. This effectively disenfranchised Black voters, as it was illegal in many southern states to teach enslaved people how to read. For many decades, the U.S. Supreme Court upheld these measures. In the 1898 Williams v. Mississippi ruling, the Court upheld the state’s poll tax, disenfranchisement clauses, grandfather clause, and literacy tests on the basis that the new state constitution didn’t “discriminate between the races, and it has been shown that the administration wasn’t evil: only that evil was possible under them.”

In the mid-20th century, popular and congressional momentum started to build for a greater federal role in protecting voter rights. In 1944, the Supreme Court struck down Texas’s all-white primary election system in Smith v. Allwright. NAACP Legal Defense Fund’s leader (and later the first Black Supreme Court justice), Thurgood Marshall, argued that since primaries were a controlling factor in elections, the exclusion of Black voters violated the 14th and 15th Amendments, to which the court agreed in an 8-1 decision. Activists and media also played a large role in garnering public support. The 1965 Selma to Montgomery Marches received widespread media coverage, especially when police forces brutally attacked Black activists and protestors who were marching for their right to vote. The events of “Bloody Sunday,” as it was deemed, brought this momentum to a boiling point, and the VRA was enacted, despite objections from some southern Democrats, 5 months later.

The Voting Rights Act, signed on August 6, 1965, is one of the most successful civil rights measures in history. One of the most revolutionary aspects of the statute is that it was designed to prevent discrimination before it happened by requiring certain jurisdictions with a history of racially discriminatory voting practices to seek federal approval for any changes to their electoral district maps or election policies before implementing them — a process called preclearance. Furthermore, Section 4 prohibits race- or color-based tests or devices in elections at any level of government. The most relevant section of the VRA, currently under reconsideration by the Supreme Court, is Section 2, which prohibits states or political entities from imposing race- or color-based qualifications or prerequisites in any voting standard, practice, or procedure. For the first 17 years of the VRA in action, Section 2 was only used sparingly in connection with redistricting. However, in 1982, Congress passed an amendment with bipartisan support allowing voters to challenge maps and electoral systems based on discriminatory effect, not just intent. For the first time since Reconstruction, communities of color were able to elect their preferred candidates to represent them. It is Section 2 that Louisiana v. Callais centers on, and its repeal could undo decades of civil rights progress.

What is Louisiana v. Callias?

The origins of this case date back to 2022. The United States conducts a nationwide census once every 10 years, the results of which are used to reapportion congressional seats and guide the distribution of funds. Based on population changes indicated by the Census and the number of apportioned congressional seats each state receives, states are tasked with redrawing their electoral maps. During this process, the Louisiana Legislature drew a congressional map that allowed only one Black opportunity district out of its total six, despite Black voters being a third of the state’s population. In many American states, especially in the deep south, there is strong racially polarized voting — when the political preferences of the majority race diverge from the preferences of minority race(s). In the case of Louisiana, Black voters vote overwhelmingly for Democratic candidates while white voters prefer Republican candidates. Despite Democratic Governor John Bel Edwards vetoing the map, the Republican legislative supermajority overrode his veto to pass it.

Shortly after Louisiana passed the 1-5 map, the NAACP and other parties filed suit challenging the plan under Section 2 of the VRA, in a case then-called Robinson v. Landry. Plaintiffs argued that the map “packed” Black voters into a single majority-minority district and “cracked” the remaining Black voters among the remaining districts, denying them equal opportunity to elect candidates of their choice. After a favorable ruling in the district court, the legislature pivoted to pass a 2-4 map, rectifying the VRA violations of the first map and giving Black voters more representation. However, the victory lap did not last long. A dozen “non-African American” voters filed a suit, Callais v. Landry, challenging the new map’s constitutionality in federal district court. The plaintiffs argued that the 2-4 map was an unconstitutional racial gerrymander that relied on improper racial considerations rather than race-neutral redistricting principles, in accordance with the Supreme Court’s ruling in Shaw v. Reno (1993). A divided panel of 3 judges agreed with the plaintiffs and found the map unconstitutional. The Robinson defendants, who had filed the initial 2022 complaint alongside the State of Louisiana, then appealed to the Supreme Court.

The Supreme Court then agreed to take up the case in March 2025, intending to answer whether state lawmakers had allowed race to unconstitutionally predominate the map-drawing process in their attempt to remedy the VRA violations. In oral arguments, president-director of NAACP Legal Defense Fund, Janai Nelson, challenged the logic that race predominated the Louisiana legislature’s map drawing, since the Supreme Court itself has recognized, since the Shaw v. Reno ruling, that awareness of race is always present when a legislature draws electoral lines. In fact, in Bush v. Vera (1996), the Supreme Court recognized that the decision to create majority-minority districts is not objectionable in and of itself.

In a shocking turn of events, on the last day of the Supreme Court’s term, the Court set Louisiana v. Callais for reargument on the broader question of whether Section 2 of the VRA itself is constitutional. This new framing of the question led the state defendants to abandon their commitment to back up their map, leaving the coalition of Black voters and organizations alone to defend the application of the VRA in the redistricting process. While the original ruling would have implications for Louisiana, the question being decided was narrow and would not have broader implications. By calling into question Section 2 as a whole, the Supreme Court tees up the possibility of gutting the Voting Rights Act, affecting every level of governance nationwide. Arguments in the case were wrapped on October 15, 2025, and now it is a matter of waiting for a decision, which could take until the end of June.

What are the Implications of Louisiana v. Callais?

This is not the first time that the VRA has come under attack from the Supreme Court. In fact, it has already been weakened. In the 2013 landmark case, Shelby County v. Holder, the Court struck down the provision that established a method for determining which jurisdictions had to undergo preclearance to make changes to their voting policies. This decision opened the doors for states to enact restrictive voter laws, which disproportionately made it harder for people of color to vote. On the same day as the decision, Texas officials announced they would enact the nation’s most restrictive voter ID law, which had previously been blocked by the preclearance process. Though this law was later ruled to be racially discriminatory, it was just one example of a wave of restrictive voting policies nationwide. In another example, the city of Pasadena, Texas, rushed through changes to its city council map to convert its two single-member districts to at-large districts. This diluted the growing political influence of Latino voters in the town, and it took four years of litigation to win relief.

As the Pasadena example demonstrates, the biggest impacts of Louisiana v. Callais would be at the local level. Half of all Section 2 cases have involved city councils, school boards, and non-partisan local bodies. Not only would the overturning of Section 2 clear the way for a 5-1, or even a 6-0, map to be implemented in Louisiana, but it would also open the floodgates for politicians, especially in the South, where racially polarized voting is prevalent, to replace local redistricting plans with multi-representative or at-large districts that curtail the collective power of Black voters. Minority-majority (and predominantly Democratic) districts at the congressional, legislative, and local levels in states such as Alabama, Florida, Georgia, Texas, and Mississippi would be at risk of being completely erased from the map.

What Does Callais Mean for Mid-Decade Redistricting?

In the Greek parable, The Sword of Damocles, a courtier switches places with King Dionysius, only to discover he has been forced to sit underneath a sword hanging by a single horsehair. Likewise, states across the nation are awaiting the Callais decision with bated breath, a modern Sword of Damocles ready to drop at any moment. The decision is coming amid a nationwide mid-decade redistricting battle. In July of 2025, President Donald Trump directed the Texas Legislature to undertake passing a new congressional map during a special legislative session. After a personally embarrassing 2018 Midterm performance during his first term, in which Democrats won back the House in a massive “blue wave,” Trump is determined to win big in the 2026 Midterms. In his conversations with Texas legislative leaders, he directed them to “find him” five more Republican Congressional districts. Despite more than 50 Democrats leaving the state to stall the gerrymander's passage, the +5 map was signed into law in August. The Supreme Court ruled in December that the new Republican-drawn map was permissible for the 2026 elections, overturning a lower court decision that found it discriminatory against minorities.

The situation in Texas set off a chain reaction across the country, with both Democratic and Republican states scrambling to redraw their Congressional maps in a race for the upper hand in the 2026 midterms. California voters approved Proposition 50, allowing for the temporary suspension of the state’s independent redistricting commission to counter Texas’s partisan gerrymander with one of their own, adding 5 new Democratic Congressional seats. As of early 2026, six states have already implemented new Congressional maps: California, Texas, Missouri, North Carolina, Ohio, and Utah, and Florida is starting its redistricting process. Four states have introduced legislation proposing or authorizing new maps: Maryland, South Carolina, Virginia, and Washington; and lastly, four states are currently caught in litigation: Alabama, Louisiana, North Dakota, and Wisconsin.

A Louisiana v. Callais decision before the 2026 Midterms would throw gasoline on the current redistricting fire, opening the floodgates for Republican legislators to draw more extreme maps that erase majority-minority Democratic districts. However, they are running out of time. The Supreme Court typically does not release its most contentious decisions until the end of its term in June. States typically require maps to be finalized at least six weeks before primary elections. The Court’s timing will determine whether the impacts of this case are felt immediately in the 2026 midterms or pushed to later election cycles.

Conclusion

Louisiana v. Callais is about more than a single map; it is about whether minority communities will continue to have meaningful political representation. Section 2 of the VRA has been a crucial safeguard against racial vote dilution for decades. To strike it down would be to weaken one of the last remaining major federal protections for voting rights.

This case does not arise in isolation: In recent years, key civil rights protections have steadily been narrowed, from the weakening of preclearance in Shelby County v. Holder to the expansion of restrictive voting laws across the country. A decision gutting Section 2 would mark another step in this broader retreat from federal civil rights enforcement. In a time of escalating redistricting battles, removing this safeguard could accelerate the erosion of minority-majority districts nationwide. The Court’s ruling will not only affect the 2026 elections but also signal how far the nation is willing to withdraw from its commitment to equal representation under the law.
