When the remedy becomes the violation: voting rights & equal protection

For decades, two strands of federal law have pulled in opposite directions when it comes to race and representation in elections. On the one hand, the Voting Rights Act sometimes requires states to consider race when drawing district lines, so that minority communities have a fair shot at electing the candidates they prefer. On the other hand, the Constitution's Equal Protection Clause warns states not to draw district lines based on race. For years the Court assumed those two commands could coexist. In April 2026, the Supreme Court's decision in Louisiana v. Callais resolved that tension by raising the bar for proving a Section 2 violation. How that plays out will depend on how lower courts apply the new rules over the coming election cycles.

What’s contested

The majority calls Callais an “update” to the Voting Rights Act framework (Court opinion, p. 26). The dissent and major civil-rights groups call it an “evisceration” of §2 that will make these cases rarely winnable. This dashboard presents both.

The central legal tension

Two parts of federal law pulling in opposite directions — and the Court's new answer for how to handle that.

Voting Rights Act · Section 2

States have to fix vote dilution

Vote dilution means district lines drawn so a minority community's votes don't count for as much — for example, by spreading those voters thinly across many districts so they can't win in any. When voting in a state breaks sharply along racial lines and minority voters consistently can't elect candidates they prefer, Section 2 of the Voting Rights Act can require the state to fix that — usually by redrawing district lines. Since Congress amended the law in 1982, plaintiffs don't have to prove the state meant to discriminate; they can win by showing the outcomes were discriminatory.

vs.
14th Amendment · Equal Protection

Race can't be the main reason for a district line

The Constitution's Equal Protection Clause says that if race is the dominant factor behind where a district line goes, courts have to give that map their toughest review, and the state has to show an exceptionally strong reason for using race. This is not new: well before Callais, the Supreme Court had already read the Equal Protection Clause to forbid racial gerrymanders (Shaw v. Reno, 1993; Miller v. Johnson, 1995). What Callais changed is the exception — the Court now accepts "compliance with Section 2" as a strong-enough reason only when Section 2, as the Court now reads it, in fact requires race-conscious districting (Court opinion, pp. 23–31); the dissent and the four civil-rights organizations quoted in the Voices section read the new proof requirements as unlikely to be met in most cases.

What Louisiana did — and what the Court undid

Both the majority opinion and the dissent organize their analyses around these four maps (Court opinion, pp. 11–15). Read the four-step chronology below first — it shows how Louisiana added a second majority-Black district under a lower court's order in Robinson v. Ardoin, then had that map struck down by the Supreme Court. The four figures below are reproduced from the Court's opinion at pages 11, 12, 14, and 15.

Before & after the Supreme Court

Louisiana added a second majority-Black district. The Court took it back.

Step 1 · 2013–2022
1 Black district
Louisiana's map before the 2020 census. Of its six districts, only one had a Black majority — District 2, anchored in New Orleans, in the state's southeast.
Step 2 · 2022 — HB1
Still 1 Black district
The 2020 census forced a redraw, but HB1 kept the same setup — still just one majority-Black district (District 2) in the southeast.
Step 3 · 2024 — SB8
2 Black districts
After a federal court found HB1 likely violated Section 2, Louisiana added a second majority-Black district — District 6, a long shape running from Shreveport in the northwest to Baton Rouge in the southeast.
Step 4 · Apr 2026 — SCOTUS
Back to 1 Black district
The Supreme Court struck down SB8, ruling the second district was drawn mainly by race. Louisiana goes back to a map with one majority-Black district.

The whole legal fight: the Supreme Court was reviewing a lower-court ruling that required Louisiana to add the second Black district. The Court reversed direction — saying the remedy itself violated the Constitution.

The four maps as they appear in the Court's published opinion (pp. 11–15)

These are reproduced directly from the Supreme Court's opinion. The bat-shaped District 2 (around New Orleans) and the long, narrow District 6 (cutting across the state) are the focus of the dispute. To orient yourself: on all four maps, New Orleans and Baton Rouge sit toward the southeast, and Shreveport is in the far northwest corner.

HB1 — enacted 2022

After the 2020 census, Louisiana kept its six congressional seats but had to redraw the lines. HB1 looked a lot like the old map — still just one majority-Black district. A federal court ruled in Robinson v. Ardoin that HB1 likely violated Section 2 by "packing" Black voters into District 2 and "cracking" them across the other five districts.

Figure 3 · Court opinion, p. 14
SB8 — the disputed map
Louisiana SB8 map
In response to that ruling, Louisiana drew SB8. It keeps the original majority-Black District 2 and adds a second one — District 6 (in green) — that stretches about 250 miles from Shreveport in the northwest, through Alexandria and Lafayette, all the way to Baton Rouge in the southeast. The Court found that Louisiana drew the line that way to protect three Republican incumbents the state wanted to keep in office: Speaker Mike Johnson, Majority Leader Steve Scalise, and Representative Julia Letlow.

Figure 4 · Court opinion, p. 15
Robinson plaintiffs' illustrative maps
Robinson illustrative maps
These are four example maps the Section 2 plaintiffs in Robinson offered to show that a second majority-Black district was possible. Each version drew a second district running northeast — connecting Black communities in Baton Rouge and Lafayette with rural Black communities to the northeast (not northwest, as in SB8). The Supreme Court rejected these examples on a technicality: because they would have put one of the incumbents Louisiana wanted to protect (Rep. Letlow) into a heavily Democratic district, they didn't meet "all the State's legitimate goals." Under the Court's new rules, that's enough to throw out the example map — and with it, the Section 2 case.
Source: Court opinion, p. 15, Louisiana v. Callais (2026)
Why this matters. Under the new rule, a Section 2 plaintiff's illustrative map must satisfy every political goal the state names — including protection of specific incumbents (Court opinion, pp. 23–25). In Louisiana, the Robinson plaintiffs' four illustrative maps were rejected because one of them would have placed an incumbent the state chose to protect (Rep. Letlow) into a heavily Democratic district. The dissent argues — and the four civil-rights organizations quoted in the Voices section concur — that this dynamic gives states broad latitude to set goals plaintiffs will struggle to meet (Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, p. 3). How often this plays out across states is an empirical question that will be answered as lower courts apply the new rule.

What is Callais — and why people are upset

For thirty years, the Court had ducked one big question: can "we were trying to follow the Voting Rights Act" ever be a good enough reason for a state to consider race when drawing district lines? Callais finally answers — yes, but only when the VRA, as the Court now reads it, actually requires the state to do so. How often that will be is contested. The dissenters call the Court's four tightenings of the Gingles framework an "evisceration" of Section 2 (Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, p. 3); NAACP LDF, the Brennan Center, the Campaign Legal Center, and the National Urban League all predict Section 2 cases will rarely succeed in most of the country going forward. The majority disagrees, casting its changes as an "update" (Court opinion, p. 26). The empirical answer — how often, and where — will come from how lower courts apply Callais over the next several election cycles, and we update this dashboard as that evidence accumulates.

What the Court ruled (the “holding”)
"Because the Voting Rights Act did not require Louisiana to create an additional majority-minority district [a district where most voters belong to a racial minority], no compelling interest justified the State's use of race in creating SB8, and that map is an unconstitutional racial gerrymander [a district whose lines were drawn primarily based on race]."

All six Justices in the majority were appointed by Republican presidents; all three dissenters by Democratic presidents. The 6–3 vote tracks the nominating party of each Justice exactly — readers can weigh how unusual that is relative to recent voting-rights decisions such as Allen v. Milligan (2023, 5–4 with Roberts and Kavanaugh joining the more liberal Justices).

What changed

The Court didn't formally overrule the older voting-rights cases (Thornburg v. Gingles from 1986, or Allen v. Milligan from 2023). Instead, it "updated" how those cases work in four ways. The majority frames these as an update consistent with Section 2's text (Court opinion, p. 26); the dissent and civil-rights organizations quoted below characterize them as tightenings that raise the plaintiff's proof burden at each step (Kagan, J., dissenting, Court opinion, p. 3):

  1. If you're suing, your example map can't use race. Plaintiffs in voting-rights cases usually offer a sample district map to show the state could have done better. That sample now can't take race into account — and has to meet all the state's other goals, like protecting specific incumbents the state chose to protect.
  2. You have to prove the voting split is about race, not just party. It's not enough to show that Black voters mostly vote for Democrats and white voters mostly vote for Republicans. You have to show the racial split is something more than the partisan split.
  3. Old history counts for less. A state's history of voter suppression — and present-day inequalities that trace back to that history — now get "much less weight" than they used to. The Court wants courts focused on whether the state is intentionally discriminating right now.
  4. You essentially have to prove intent. Even though Section 2 was specifically amended in 1982 to remove the intent requirement, the Court now reads it to require strong evidence that the state intentionally drew lines to give minority voters less power because of race.

Court opinion, pp. 23–31. The three dissenting Justices say these changes "eviscerate" Section 2 — see Majority & Dissent below.

Why this is controversial: in their own words

Where the six-Justice majority and the three-Justice dissent disagree most sharply. Each pair below has a quick framing of what's at stake, then the quotes themselves.

Who joined the dissent. Justice Kagan wrote the dissent. Justice Sotomayor — the first Latina to serve on the Court — and Justice Ketanji Brown Jackson — the first Black woman on the Court — joined it in full. Justice Jackson did not write separately; on the page, the dissent speaks for all three.

Is the Court "updating" the law or rewriting it?

The majority describes its changes as merely an update; the dissent says the changes gut the law.

"This interpretation of Section 2 does not require abandonment of the Gingles framework. We need only update the framework so it aligns with the statutory text and reflects important developments since we decided Gingles 40 years ago." Majority opinion, Court opinion, p. 26
"The majority claims only to be 'updat[ing]' our Section 2 law, as though through a few technical tweaks. But in fact, those 'updates' eviscerate the law, so that it will not remedy even the classic example of vote dilution." Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, p. 3

Can race and party really be separated?

The majority says plaintiffs have to prove the racial split is something more than the partisan split. The dissent says that in most of the country today, the two are so intertwined that the requirement is impossible to meet.

"When a State defends a districting scheme on the ground that it was drawn for partisan purposes, plaintiffs have a 'special' burden to overcome. To prevail, the plaintiff must disentangle race from politics by proving that the former drove a district's lines." Majority opinion, Court opinion, p. 25
"[T]he majority's new test, when those two facts coexist — which is almost everywhere Section 2 still has purchase — a plaintiff cannot prevail by showing that a redistricting resulted in the dilution of minority voting power. Rather, a plaintiff will have to show — contrary to Section 2's clear text and design — that the legislators were 'motivated by a discriminatory purpose.' And that, as Section 2's drafters knew, is well-nigh impossible." Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, pp. 3–4

Has the country moved past needing the Voting Rights Act?

The majority frames the lack of present-day intentional discrimination as a success story. The dissent sees the Court's own decisions over the past decade as a steady dismantling of the law.

"'[I]n large part because of the Voting Rights Act, our Nation has made great strides' in eliminating racial discrimination in voting. And if, as a result of this progress, it is hard to find pertinent evidence relating to intentional present-day voting discrimination, that is cause for celebration." Majority opinion, Court opinion, p. 31 (quoting Shelby County)
"Today's ruling is part of a set: For over a decade, this Court has had its sights set on the Voting Rights Act. In 2013, the Court made a nullity of Section 5… In 2021, the Court did half what was needed to raze [Section 2] too. And finally, today, the last piece — Section 2 as applied to redistricting." Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, p. 4

Thomas and Gorsuch would go further

Justice Thomas wrote separately (joined by Justice Gorsuch) to say the Court should have gone all the way. In their view, Section 2 shouldn't apply to district maps at all — ever.

"As I explained more than 30 years ago, I would go further and hold that Section 2 of the Voting Rights Act does not regulate districting at all… no Section 2 challenge to districting should ever succeed." Thomas, J., concurring (joined by Gorsuch, J.), Court opinion, p. 2

The argument about historical evidence

This may be the deepest disagreement in the case. The dissent points to Louisiana's specific history: in 1896, about 130,000 Black Louisianans were registered to vote. By 1904 — just eight years later, after the state put new rules in place — only 1,342 were left on the rolls (Kagan, J., dissenting, Court opinion, p. 8, citing the historian Alex Keyssar). For the dissenters, that history is part of why Section 2 exists and how present-day claims should be judged. The majority's response: "[D]iscrimination that occurred some time ago, as well as present-day disparities that are characterized as the ongoing 'effects of societal discrimination,' are entitled to much less weight" (Court opinion, pp. 30–31). The disagreement about how much weight history should carry is, in important ways, the whole case.

Louisiana registered Black voters, 1896 → 1904
Cited in Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, p. 8 (citing A. Keyssar, The Right to Vote 91). The majority holds such historical data is entitled to "much less weight" in Section 2 analysis.

Reactions from civil-rights and voting-rights organizations

Statements from civil-rights and voting-rights organizations responding to Callais, quoted verbatim from each organization's public statement on or after the April 29, 2026 decision. These organizations opposed the ruling; the Court majority's contrary reasoning is quoted in the paired sections above.

"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. 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." Derrick Johnson, President & CEO, NAACP (Apr. 29, 2026)
"A day of infamy for the Court … a day of devastation for our democracy. The Supreme Court's decision eviscerated Section 2 of the Voting Rights Act, a critical and sacred civil rights protection. Make no mistake: this decision threatens the political power of Black communities." Janai Nelson, President & Director-Counsel, NAACP Legal Defense Fund (Apr. 29, 2026)
"Yesterday's U.S. Supreme Court decision in Louisiana v. Callais is exactly what it is: a power grab that silences Black voters. The decision clears a path for all states, not just Louisiana, to impose new, nearly insurmountable barriers to proving violations of the Voting Rights Act. In short, the Court has effectively told states that they may systematically weaken Black voting strength so long as they avoid leaving behind explicit evidence of intent." Joint statement, National Urban League & Urban League of Louisiana (Apr. 30, 2026)

What are Section 2, Section 3, and the other parts of the VRA?

Five parts of the 1965 law that have shaped voting-rights enforcement. After Shelby County (2013) and now Callais (2026), most of these tools are weaker or unavailable than they were just over a decade ago. (In legal documents you’ll see these written as “§2,” “§3,” etc. The “§” symbol just means “Section.”)

Click any card to see where it’s referenced elsewhere in this dashboard.

Only Congress can bring Section 5 back. The John Lewis Voting Rights Advancement Act would write a new list of states covered by Section 5 — bringing federal sign-off back into use. It passed the House but stalled in the Senate. Courts can't restore Section 5; only a new law can.

1965
The Voting Rights Act becomes law
A landmark federal law to end racial discrimination in voting. Combines two tools: Section 2 (rules against discrimination, enforceable in court anywhere in the country) and Section 5 (requires certain states with histories of voter suppression to get federal sign-off before changing voting rules).
[ click to expand ]
The march from Selma to Montgomery — and the violence on "Bloody Sunday" — pushed Congress to pass the law. The pairing of Section 2 and Section 5 was meant to be a one-two punch: Section 5 to stop bad laws before they took effect, and Section 2 to fight discrimination wherever it appeared.
1980
City of Mobile v. Bolden
The Supreme Court reads Section 2 to require plaintiffs to prove the state was deliberately discriminating. That's a very hard thing to prove — and the ruling made voting-rights cases very hard to win.
[ click to expand ]
Two years later, Congress responded by changing the law itself.
1982
Congress strengthens Section 2
Congress amends Section 2 to say plaintiffs no longer have to prove the state meant to discriminate — they can win by showing the outcomes were discriminatory. A direct response to the 1980 Mobile ruling.
[ click to expand ]
The updated text says a violation happens when, looking at the whole picture, the political process isn't equally open to members of a protected racial group — they have less opportunity than others to participate and elect candidates they prefer.
1986
Thornburg v. Gingles
The Supreme Court spells out a three-part test for Section 2 cases. This is the framework courts used for the next 40 years — until Callais.
[ click to expand ]
The three parts: (1) the minority community has to be large and clustered enough to form a majority in some realistic district; (2) members of the community generally vote the same way; (3) the white majority generally votes against the minority's preferred candidates often enough to defeat them. If those three are met, courts look at the broader picture too.
1993
Shaw v. Reno
The Supreme Court rules that if race is the main reason behind a district's lines, courts have to give that map their toughest review. This is the rule that would later make race-conscious VRA remedies risky.
[ click to expand ]
The seed of the tension Callais would later resolve: Section 2 sometimes pushes states to consider race in drawing maps, while the Equal Protection Clause warns states not to.
2009
Northwest Austin Municipal Util. Dist. v. Holder
Chief Justice Roberts signals that the list of states covered by Section 5 is outdated — a warning of what was coming.
[ click to expand ]
The Court doesn't strike down the Section 5 list in this case, but it puts down a marker: "things have changed in the South." That framing returned four years later in Shelby County.
2013
Shelby County v. Holder
The Court strikes down the list of states covered by Section 5. This effectively shuts down federal pre-approval of voting changes. From here on, almost all VRA enforcement has to happen through Section 2 lawsuits.
[ click to expand ]
Justice Ginsburg's dissent in this case (often quoted in Justice Kagan's Callais dissent) warned that gutting Section 5 would lead to a wave of restrictive voting laws.
2021
Brnovich v. Democratic National Committee
The Court narrows Section 2 for laws that restrict how people can vote (early voting rules, ID requirements, etc.). The Callais dissent calls this "half what was needed to raze" Section 2.
[ click to expand ]
According to a legal scholar cited in the Callais dissent, since Brnovich, no Section 2 lawsuit challenging a voting restriction has succeeded — no matter how discriminatory the law was in practice.
2023
Allen v. Milligan
The Court upholds the older Gingles framework and orders Alabama to draw a second majority-Black district. After a decade of rulings narrowing the VRA, this was a surprise — Section 2 still had real force.
[ click to expand ]
Alabama had argued for a new approach the Court called too "single-minded." Three years later, the Callais majority would treat Allen as a narrow case that didn't decide today's questions.
2026
Louisiana v. Callais
The Court resolves the long-pending tension between Section 2 and the Equal Protection Clause — and in doing so, makes Section 2 much harder to win. Louisiana's new map is struck down as a racial gerrymander; the Court rules Section 2 didn't require Louisiana to draw it in the first place.
[ click to expand ]
Six Justices in the majority: Alito wrote the opinion; Roberts, Thomas, Gorsuch, Kavanaugh, and Barrett joined. Thomas (with Gorsuch) wrote separately saying Section 2 shouldn't apply to districting at all. Three Justices dissented: Kagan, Sotomayor, and Jackson — calling the decision the "now-completed demolition of the Voting Rights Act."

The Gingles test, then and now

For 40 years, voting-rights cases have followed a three-step test from Thornburg v. Gingles (1986). Callais doesn't throw out that test — the Court explicitly retains the Gingles framework (Court opinion, p. 26) — but it raises the evidentiary bar at each step (Court opinion, pp. 23–31). Whether that change shifts case outcomes substantially or modestly is the contested question between majority and dissent.

Step 1: Could the state have drawn a different map?

Before Callais

Show an example map with an additional majority-minority district

  • To prove a Section 2 case, you offer an example map showing the state could have drawn one more district where minority voters would be the majority.
  • That example map could take race into account.

After Callais

Your example map can't use race — and has to satisfy every goal the state names

  • The map you offer can't take race into account at all.
  • It also has to meet every goal the state lists — including which specific incumbents the state wants to keep in their current seats.
  • If your map fails on either count, the Court won't even consider it.

Steps 2 and 3 ask different questions — one about how minority voters vote, one about how the white majority votes — but both rely on the same kind of evidence: a statistical look at how different racial groups voted across many elections.

Step 2: Are minority voters politically cohesive?

Before Callais

Show minority voters tend to prefer the same candidates

  • Shown through a statistical analysis of voting patterns across many elections.
  • General-election patterns — e.g., Black voters predominantly supporting one party's candidates — were generally accepted as evidence of minority political cohesion (Thornburg v. Gingles, 478 U.S. 30, 56 (1986)).

After Callais

Show that cohesion is racial, not just partisan

  • Same statistical question, but the analysis must now distinguish racial cohesion from partisan cohesion.
  • Showing minority voters consistently support one party is no longer sufficient if the pattern can be explained as party preference rather than racial group preference (Court opinion, p. 30).

Step 3: Does white bloc voting usually defeat the minority’s candidate?

Before Callais

Show the white majority votes as a bloc against the minority’s choice

  • Demonstrate the white majority votes sufficiently as a bloc to usually defeat the minority’s preferred candidate. Some cross-racial voting is fine, as long as the minority’s candidate still usually loses.
  • Showing that white voters predominantly supported the opposite party’s candidates in general elections was generally accepted as evidence of white bloc voting (Thornburg v. Gingles, 478 U.S. 30, 56 (1986); Ansolabehere, Persily & Stewart, 123 Harv. L. Rev. 1385 (2010)).

After Callais

Show the bloc voting is racial, not just partisan

  • You have to prove the white-majority pattern can’t be explained simply by which party white voters support.
  • The Court flatly says that a Black-Democrat / white-Republican split, on its own, “proves nothing” (Court opinion, p. 30).
  • The kind of evidence that still works: showing different racial groups vote differently even within the same party’s primary — isolating race from party.

The big-picture test: looking at all the evidence together

Before Callais

Courts weighed history, social conditions, and current patterns together

  • Courts looked at the full picture: the state's history of discrimination in voting, ongoing economic and educational inequalities tied to that history, racially polarized voting today, lack of minority electoral success, and other factors.

After Callais

Focus on whether the state is intentionally discriminating right now

  • A state's history of voter suppression — and the inequalities that history left behind — now get "much less weight."
  • What matters is current data and current evidence pointing to present-day intentional discrimination by the state.

In plain terms: the majority says a map breaks Section 2 only when there is strong proof the state drew the lines to disadvantage minority voters because of their race — not merely that the lines ended up hurting them.

"Section 2 imposes liability only when the evidence supports a strong inference that the State intentionally drew its districts to afford minority voters less opportunity because of their race." Majority opinion, Court opinion, p. 26

The dissent's bottom line: under the old rule, plaintiffs could win by showing a map resulted in weakened minority voting power; the dissent warns the new rule lets a state dilute that power without consequence.

"Under that revised version, a person has a good Section 2 claim if the challenged state action, in the 'totality of circumstances,' 'results in' an electoral system 'not equally open' to members of his racial group… But no longer. Under the Court's new view of Section 2, a State can, without legal consequence, systematically dilute minority citizens' voting power." Kagan, J., dissenting (joined by Sotomayor & Jackson, JJ.), Court opinion, pp. 2–3

Evidence and methods: where social science does the work

Historically, voting-rights cases have relied on empirical evidence developed and tested in an adversarial courtroom — opposing experts, cross-examination, and a judge acting as gatekeeper — rather than through academic peer review. Courts leaning on this kind of research is nothing new: in Brown v. Board of Education (1954), the Justices pointed to social-science studies on the harm segregation did to Black children, and the Section 2 test at the heart of Callais — from Thornburg v. Gingles (1986) — was itself built on expert analysis of how people actually vote. After Callais, the burden of proof attached to that evidence has shifted, reshaping which empirical claims plaintiffs can realistically pursue. (The specific step-by-step changes are detailed in the Decision section's "What changed" cards and the Gingles, Then and Now comparison.)

Proving voters are split along racial lines (“racially polarized voting”)

This is the part of a Section 2 case where social scientists do the work. Racially polarized voting means voters of different races consistently prefer different candidates — the pattern plaintiffs have to prove. Since no one records each voter's race, experts estimate how each racial group voted by running statistical methods on precinct-level results (King 1997; Greiner & Quinn 2009). Those methods involve judgment calls — which elections to count, how to handle small numbers — that can change the answer. And after Callais, experts have to go one step further: show that the divide is really about race, not just party (Court opinion, p. 25). That takes more detailed data, such as results from primaries where every candidate is from the same party.

How courts decide which expert testimony to trust

Before a jury or judge ever hears from an expert, the judge plays "gatekeeper" and decides whether that expert's evidence is solid enough to come in at all — using a test the Supreme Court set in 1993 (Daubert v. Merrell Dow Pharmaceuticals). To clear that bar, the evidence should be:

  • Based on a theory or method that can actually be tested
  • Published or reviewed by other experts
  • Have a known rate of error
  • Accepted by the relevant scientific community
The gap between court evidence and academic evidence. Even with the Daubert standard, courts don't require things academic journals would: pre-registering what analyses you'll run, sharing your data and code, replication, or disclosing alternative models you tried. The only real check is the other side's expert pushing back on cross-examination — not peer review.

Source list with scholarly works and government reports cited above is consolidated in the Sources section at the bottom of this dashboard, organized by topic (Doctrine & the Court; Racially polarized voting & methods; History of voting suppression; Representation → outcomes; Section 3 bail-in & remedies; Local elections & school boards).

Does this affect your community? From state legislatures to school boards

A Supreme Court ruling about Louisiana's congressional map sounds far away from a local school board. It isn't. Callais's new rules apply to Section 2 challenges at every level — state legislatures, county commissions, city councils, and school boards. Many states and counties drew race-conscious maps under the older Gingles framework; those maps now face higher justification requirements under Callais (Court opinion, pp. 23–31). Whether they get redrawn legislatively, challenged in court, or left in place will resolve case-by-case. The Brennan Center is tracking which states' maps are most likely to be relitigated.

Section 2 wins, from Congress to the school board

One real Section 2 win at each level of government. The school-board card includes two additional examples (Uvalde and Chamberlain) as foundational and recent context.

StateAllen v. Milligan 599 U.S. 1 (2023) · Alabama congressional & state-legislative redistricting
Alabama drew a 2021 congressional map with one majority-Black district despite Black residents making up roughly a quarter of the state's population. Section 2 plaintiffs (Milligan, Caster, and Singleton) showed a second majority-Black district could reasonably be drawn. The Supreme Court — in a 5–4 ruling written by Chief Justice Roberts and joined by Justice Kavanaugh — upheld the Gingles framework and ordered Alabama to add a second majority-Black district. Milligan held the §2 line for three years, until Callais changed the rules.
CountyUnited States v. Charleston County 365 F.3d 341 (4th Cir. 2004) · South Carolina county council
The U.S. Department of Justice sued Charleston County, South Carolina, arguing the county's at-large method for electing the County Council diluted Black voting strength under Section 2. After trial, the district court found the at-large system gave Black voters less opportunity to elect candidates they preferred; the Fourth Circuit affirmed. The county was ordered to adopt a single-member-district plan.
CityMontes v. City of Yakima 40 F. Supp. 3d 1377 (E.D. Wash. 2014) · Washington city council
Latino voters — represented by the ACLU — sued the City of Yakima over its at-large city-council elections. Despite Latinos being roughly 40% of the city's population, no Latino candidate had ever been elected to the council since the at-large system was adopted in the 1970s. The court found the system violated Section 2 and ordered Yakima to switch to single-member districts. In the first district-based election in 2015, three Latino candidates were elected to the council — the first Latino representation in the city's history.
School BoardClerveaux v. East Ramapo CSD 984 F.3d 213 (2d Cir. 2021) · New York
Black and Latino residents — represented by the NAACP and NYCLU — sued East Ramapo over its at-large school-board elections. The trial court found the at-large system meant Black and Latino voters' preferred candidates consistently lost; the Second Circuit affirmed. The case noted a stark divide: 92% of public-school students were Black or Latino, while 98% of private-school students were white, and the board was favoring private over public schools. The court ordered the district to switch to nine wards, three majority Black and Latino.
Other school-board Section 2 cases worth knowing

United States v. Uvalde CISD (625 F.2d 547, 5th Cir. 1980, Texas) — foundational case establishing Section 2 reaches school boards. Roughly half of Uvalde's population was Mexican-American, but only one Mexican-American had ever been elected to the seven-member board; the Fifth Circuit found the at-large system was diluting Mexican-American voting strength.

United States v. Chamberlain SD (D.S.D. 2020, South Dakota) — DOJ challenged the at-large school-board elections for diluting American Indian voting strength; settled June 2020 with a new election method.

Two downstream effects to watch

Effect 1

The "only one in the room" problem

When only one or two minority lawmakers serve in a state legislature, county commission, city council, or school board, they face a structural problem: it is much harder to build the kind of coalitions needed to get issues onto the agenda, sustain attention through multiple sessions, or get hearings on bills that matter to underrepresented communities.

This isn't about symbolism. It changes which policy ideas actually make it into law — and which never get heard at all.

Effect 2

What this actually affects in daily life

The bodies whose elections Callais reaches make the decisions that touch people every day. When the racial composition of those bodies shifts, the decisions tend to shift too. Research has documented this across three levels:

  • School boards decide school funding, school closures, what gets taught, and how schools are held accountable. (Kogan, Lavertu & Peskowitz 2021)
  • State legislatures decide Medicaid expansion, voting-law design, judicial selection, and how schools are funded. (Hajnal 2010; Grumbach 2022)
  • County and city government decide law-enforcement oversight, public-defender funding, and what prosecutors prioritize. (Benjamin 2017; Anzia 2014)

How strongly representation shapes these outcomes varies by institution, by community, and by the specific decision in question. The open research question is not whether the link exists, but how strong it is and under what conditions — see Open Questions > Empirical for the substantive discussion.

The reach of Section 2 is broad. The Justice Department's own description: Section 2 cases have been brought against states, counties, cities, school districts, and special districts. They've challenged at-large systems, district-based systems, and mixed systems. The Supreme Court's 1991 ruling in Chisom v. Roemer added that Section 2 also reaches judicial elections. Callais doesn't change which bodies Section 2 applies to — but it makes winning a case against any of them much harder.

Section 3 bail-in: the tool still on the table

← See Section 3 in the VRA Sections grid

Section 3 (often called “Section 3 bail-in”) lets a federal court, after finding a state intentionally discriminated in voting, put that state under federal review for a set period — meaning the state has to get federal approval before changing voting rules. It's the same kind of oversight Section 5 used to provide automatically before the Supreme Court shut Section 5 down in Shelby County (2013), but applied case-by-case. With Section 5 inoperative and the Section 2 bar raised by Callais, Section 3 is now the strongest remaining tool that can be used through the courts. Travis Crum's 2010 Yale Law Journal article first argued for treating Section 3 as an underused tool; Callais revives that question (Crum, "The Voting Rights Act's Secret Weapon," 119 Yale L.J. 1992 (2010)).

What happens next, and what’s being done

Options and approaches that researchers, policymakers, and educators are weighing, grouped by audience. These describe avenues under discussion in the field — not positions or recommendations of this dashboard.

For Researchers
  • Press for stronger methods in court. What would the expert evidence in voting-rights cases look like if it had to meet the standards a journal uses — registering analysis decisions in advance, sharing data and code, allowing replication, listing the alternative methods you tried?
  • Define what "current conditions" should mean. Courts now insist on present-day evidence of discrimination, but no one has settled what that means in practice. Produce a defensible standard.
  • Strengthen the representation–resources literature. Existing work (Hajnal 2010 on city politics; Kogan, Lavertu & Peskowitz 2021 on school boards) documents conditional effects, but causal identification is hard and findings vary by institution and outcome measured. Newer designs — close-election RDDs, panel data on local resource allocation — could clarify where the link is strongest and where it is contingent.
  • Build a model Section 3 case file. What kind of historical and current evidence would meet the higher "intentional discrimination" bar that Section 3 requires — and the more demanding proof Section 2 now requires after Callais? Develop the template.
  • Study the "onliness" effect. Compare how legislative bodies function with one or two minority members versus those with a critical mass.
For Policymakers
  • Restoring Section 5 through Congress. Many legal scholars and civil-rights groups have proposed restoring federal preclearance; the John Lewis Voting Rights Advancement Act would do so by writing a new coverage formula. Only Congress can take that step; courts cannot.
  • State-level voting-rights laws. States can pass their own voting-rights acts that go beyond the federal floor. California, New York, Virginia, Connecticut, Oregon, and others already have. These state laws aren't affected by Callais.
  • Independent redistricting commissions. In states that use commissions instead of letting the legislature draw the maps, who's on the commission and how transparent the process is matters a lot. There's room for reform here that doesn't depend on Congress or the courts.
  • Section 3 requests in litigation. Some advocates argue that including a Section 3 federal sign-off request in the relief sought should become routine rather than exceptional.
  • Auditing local at-large election systems. Catalog the school boards, county commissions, and special districts in your area that still use at-large elections. Whether any specific system would lose a Section 2 case on the merits is a factual question that depends on the local record (see Clerveaux v. East Ramapo, 2d Cir. 2021; United States v. Chamberlain SD, D.S.D. 2020 for examples of at-large systems that were successfully challenged). One consistent practitioner observation in this area is that capacity to bring cases — not the substantive merits — often determines whether at-large systems are challenged (NAACP LDF, case briefings).
For Educators
  • Trace the ripple effect to local school boards. Section 2 reaches school boards too — East Ramapo, Chamberlain, and Uvalde are accessible entry points for showing how a Supreme Court ruling about a Louisiana congressional map ends up shaping local control.
  • Use the Court's actual maps as a primary source. The four figures in this dashboard are the images the Justices were studying. Pair them with the Section 2 doctrine to make the case concrete.
  • Show how statistics decide these cases. Whether voters of different races back different candidates is proven with data analysis by expert witnesses — and courts weigh that evidence under their own gatekeeping rules, not academic peer review. A concrete hook for civics, statistics, and research-methods classes.
  • Bring the “only one in the room” problem to life. When only one or two members of any underrepresented group serve in a body, they face greater difficulty building coalitions, pushing items onto the agenda, or sustaining attention across meetings — even when they're talented and well-prepared. Students see the same dynamic in student government, club leadership, faculty senates, and other small bodies. Use those settings as a starting point, then connect to what it means for a state legislature or city council.

Open questions

Where the law is unsettled and worth watching. We've framed these as questions to investigate, not answers.

Timing
How does the rule against last-minute election changes interact with Callais?
The Purcell doctrine (Purcell v. Gonzalez, 549 U.S. 1 (2006)) directs federal courts to avoid changing election rules close to an election. The Court has not articulated a specific cutoff date. As lower courts apply Callais's new rules to pending cases, the interaction between the two doctrines will be tested in litigation; scholars and practitioners have flagged this as a likely area of dispute.
Compliance
Is there a safe way to comply with Section 2 after Callais?
Race-conscious districting is permitted only when Section 2 — read narrowly — requires it. With proof requirements tightened at every step, what does a "safe" map look like in a state where race and party track tightly?
Methods
What evidentiary standard should social-science work in Section 2 cases meet?
Courts now require analyses that separate race from party and prove present-day intent. No agreed-on method exists. Who sets the standard — courts, professional associations, or peer-reviewed journals?
Empirical
How much does representation actually shape resources?
A substantial political-science literature finds that minority descriptive representation is associated with policy outcomes — but the magnitude depends on institution, scale, and outcome measured (Hajnal 2010; Kogan et al. 2021). Identification is hard because districts that elect minority representatives often differ on many other dimensions. The open question is not whether a link exists, but how strong, under what conditions, and for which outcomes (descriptive engagement vs. material resource allocation).
Institutional
Court, Congress, or states — whose view of "fixing discrimination" wins?
The dissent says Congress already settled this when it amended Section 2 in 1982; as it puts it, "Only [Congress has] the right to say [the VRA] is no longer needed — not the Members of this Court." The majority holds that courts must read Section 2 to stay within the limits the Constitution sets. Which institution has the final word is the open question.
Strategy
How should advocates rebalance Section 2, state laws, Section 3, and other tools?
Federal Section 2 is harder; state VRAs are stronger in some places; Section 3 is underused; state legislative reform is slow but real. The strategic question is which to invest in, where, and why.

Glossary

Plain-language definitions for the legal terms used throughout this dashboard. Type to search.

Vote dilution
When the way district lines are drawn weakens the political power of a minority community as a whole. Even if every individual still gets to vote, the lines can be drawn so the community can't elect candidates it prefers. Classic methods: "packing" voters into one district, or "cracking" them across many.
Results test (effects test)
The rule, added by Congress in 1982, that you can win a Section 2 voting-rights case by showing the outcomes were discriminatory — without having to prove the state was deliberately trying to discriminate. Congress added this after the Supreme Court ruled in Mobile v. Bolden (1980) that intent had to be proven, which made cases nearly impossible to win.
Gingles framework
The three-part test the Supreme Court created in 1986 (in Thornburg v. Gingles) for Section 2 voting-rights cases. You have to show: (1) the minority community is large and geographically clustered enough to make a majority in some realistic district; (2) members of the community generally vote the same way; (3) the white majority generally votes the other way, often enough to defeat the minority's preferred candidates. Callais tightens what counts as proof at each step.
Racial gerrymander
A district whose lines were drawn primarily based on race. The Constitution's Equal Protection Clause forbids this unless the state has an exceptionally strong reason. This is a different kind of legal claim from a Section 2 vote-dilution case — but the two interact directly, since the state may say "we drew lines based on race because Section 2 required us to."
Strict scrutiny
The toughest level of constitutional review courts apply. When a state uses race in making a decision, courts demand the state show an exceptionally strong reason and a tight fit between that reason and what the state did. The Supreme Court has accepted only two reasons as strong enough: preventing riots in prisons, and fixing specific identified past discrimination. Callais adds a narrow third: complying with Section 2, but only when Section 2 really does require the state to consider race.
Preclearance (Section 5)
From 1965 until 2013, certain states with a history of voter suppression had to get the federal government's approval before changing any voting rules. The Supreme Court shut this down in 2013 by striking the list of covered states (Section 4(b)) in Shelby County v. Holder.
Coverage formula (Section 4(b))
The list — written into the 1965 law — of which states had to get federal pre-approval under Section 5. The Supreme Court struck this list down in 2013, which is what shut down Section 5 in practice. Only Congress can write a new list.
Bail-in (Section 3)
A still-usable part of the Voting Rights Act. If a court rules that a state intentionally discriminated in voting, the court can put that state under federal pre-approval (like Section 5 used to do) for a set period of time. Rarely used, but still on the books.
Racially polarized voting
When voters of different races consistently support different candidates. Demonstrating this is one of the things plaintiffs have to do in Section 2 cases. Done with statistical methods (the technical names are "ecological regression" and "ecological inference"). After Callais, the analysis also has to separate the racial pattern from the partisan pattern.
Senate Factors
A list of nine factors from the 1982 Senate report on the Voting Rights Act — things like the state's history of voting discrimination, racially polarized voting, gaps in education and employment, and lack of minority electoral success — that courts have used to weigh whether voting in a state is truly fair. After Callais, the history-based factors get much less weight than they used to.
Daubert standard
The test federal judges use to decide whether to let an expert witness testify. Comes from a 1993 Supreme Court case (Daubert v. Merrell Dow Pharmaceuticals). It asks whether the expert's method is testable, has been reviewed by other experts, has a known error rate, and is generally accepted in the relevant field. How well it works for social-science evidence in voting cases is uneven and depends on the judge.
Packing & cracking
The two main ways to dilute a community's voting power through how district lines are drawn. Packing: jamming a community into one district, so all their extra votes there are "wasted" — they can't influence the rest. Cracking: splitting a community across many districts, so they're a small minority in every one and can't elect anyone. The words come from 19th- and 20th-century American political slang for partisan gerrymandering tactics. After Congress amended Section 2 in 1982, courts began using the terms to describe how the same techniques are used to dilute racial-minority voting power. Both are recognized harms under Section 2.
"Onliness" dynamic
A pattern that shows up when there's only one or two members of a minority group in a legislative body. They lack the critical mass needed to build coalitions, get items onto the agenda, sustain attention across sessions, or chair committees on the issues that matter most to their communities. This is structural — about how legislative bodies function — not a comment on the individual lawmaker.
Purcell principle
A rule the Supreme Court announced in Purcell v. Gonzalez (2006): federal courts should usually avoid changing election rules close to an election, because last-minute changes can confuse voters and disrupt how elections are run. The Court has never said exactly how close is too close — that's left to lower courts, case by case.
State Voting Rights Act
A state law that mirrors or expands on the federal Voting Rights Act. California, New York, Virginia, Connecticut, Oregon, and others have passed these. Because they're state laws, they aren't affected by Supreme Court rulings narrowing the federal VRA — so they're an enforcement path that's still open even after Callais.
Ripple effect / federalism cascade
How a federal ruling on a congressional map eventually changes local decisions. Federal districts shape state legislatures; state legislatures shape what counties and school boards have to work with; those bodies make the everyday decisions about schools, services, and policy. The path from a Supreme Court opinion to a school-board decision is real, even if it's long.
Majority-minority district
A district where a racial or ethnic minority group makes up the majority of voting-age residents — so that group has a realistic chance of electing the candidates it prefers.
Chisom v. Roemer (1991)
A Supreme Court ruling that Section 2 of the Voting Rights Act applies to judicial elections — and, by extension, confirmed that Section 2 reaches school-board elections as well. The same three-part Gingles test governs.
At-large election
An election system where every voter in a town, school district, or county votes for every seat on a board — rather than the area being divided into districts that each elect their own representative. At-large systems are common in school-board, county-commission, and city-council races. They can dilute minority voting power when voting is racially polarized, because the majority can win every seat.
