Shaw v. Reno
The Supreme Court ruled that white North Carolina voters could sue over a oddly shaped congressional district that stretched 160 miles along an interstate highway to link distant pockets of Black voters, because a district drawn in such an extreme, race-based shape can itself violate the Constitution.
The decision created a new kind of legal claim: even without proof that anyone's voting power was diluted, a district so bizarre it can only be explained by race triggers the toughest constitutional test, reshaping how states can use race when they redraw election maps.
“Put differently, we believe that reapportionment is one area in which appearances do matter.”
Explaining why an extremely irregular district shape can itself raise constitutional concerns.
How it got here: A three-judge federal district court dismissed the voters' complaint against both state and federal officials, and the voters appealed directly to the Supreme Court.
The Case in Depth
What happened
After the 1990 census gave North Carolina a new congressional seat, the state legislature drew a map with one majority-Black district. The U.S. Attorney General objected under the Voting Rights Act, so the legislature created a second, extremely narrow and winding majority-Black district running along Interstate 85. Five white Durham County voters sued, arguing the map amounted to an unconstitutional racial gerrymander that segregated voters by race.
The question before the Court
Could white voters sue North Carolina for drawing a bizarrely shaped, snake-like congressional district that packed together Black voters spread across a huge area?
The Court's answer
Yes — the Court ruled that white voters could bring a lawsuit challenging North Carolina's oddly shaped majority-Black congressional district, even without showing that the map actually weakened anyone's voting power. The Court held that a redistricting plan so bizarre in shape that it rationally can be explained only as an effort to separate voters by race states a valid claim under the Equal Protection Clause, distinct from traditional vote-dilution claims.
This did not mean the map was necessarily unconstitutional. The Court sent the case back to the lower court to determine whether North Carolina could show the district was narrowly tailored to a strong enough government interest, such as complying with the Voting Rights Act, to survive the toughest level of judicial review.

Why it matters
State legislatures across the country that draw election districts partly to satisfy the Voting Rights Act now have to worry that unusually shaped, race-driven districts can be challenged in court even if no group's voting power is actually weakened. This pushed states toward more careful, evidence-based justifications whenever race plays a large role in map-drawing.
What changes now
The Supreme Court did not decide whether North Carolina's map is actually unconstitutional. It sent the case back to the district court to determine, if the voters' allegations hold up, whether the state's plan was narrowly tailored to a compelling interest, such as complying with the Voting Rights Act. The underlying legal fight over the shape of District 12 and similar maps continued in later litigation.
What this does not decide
The Court did not decide whether North Carolina's district was actually unconstitutional, whether a more compact majority-Black district elsewhere would have been lawful, or whether race-conscious districting in general is prohibited. It stressed its holding applies only to the narrow category of districts so bizarre they can only be explained by race.
Concurrences and dissents
Dissent — Justice White
“The Court today chooses not to overrule, but rather to sidestep, UJO.”White's central objection that the majority avoided directly confronting existing precedent.
Justice White argued the voters had no valid claim because they never showed the district actually reduced their political influence — the only kind of harm the Court's precedents had ever recognized. He viewed the case as functionally identical to United Jewish Organizations v. Carey, which upheld similar race-based districting, and accused the majority of manufacturing a new, unworkable cause of action based on a district's appearance rather than its real-world effect.
Dissent — Justice Blackmun
Justice Blackmun joined Justice White's dissent and added that it was ironic the Court chose this case — a challenge by white voters to a plan that finally sent Black representatives to Congress from North Carolina since Reconstruction — to recognize a new constitutional claim.
Dissent — Justice Stevens
Justice Stevens argued there is no constitutional requirement that districts be compact or contiguous, and that drawing lines to help an underrepresented group win elections is not unconstitutional just because the group is defined by race. He said allowing districts favoring rural voters, unions, or religious groups but not racial minorities was an inconsistent and perverse result.
Dissent — Justice Souter
Justice Souter argued that electoral districting should be treated differently from other race-conscious government decisions because considering race is often unavoidable and necessary to comply with the Voting Rights Act, and because simply assigning someone to one district instead of another does not deny anyone a benefit. He would have kept requiring proof of actual vote dilution rather than applying strict scrutiny based on a district's shape.
How the Court got there
The legal reasoning, step by step
- The Court explained that laws explicitly sorting people by race are presumptively suspect and normally must satisfy strict scrutiny — the toughest constitutional test, requiring a very strong government reason and a law narrowly tailored to that reason.
- Relying on earlier voting-rights cases like Gomillion v. Lightfoot (a 1960 case where a town's boundary was redrawn to exclude Black voters) and Wright v. Rockefeller, the Court reasoned that even a race-neutral-looking map can be treated as a race-based law if its shape is so bizarre it 'rationally cannot be understood as anything other than an effort to segregate voters' by race.
- The Court distinguished this claim from ordinary vote-dilution claims, which require proof that a district actually weakened a group's voting power. It held that an extremely irregular, race-driven district can cause a separate constitutional harm — reinforcing racial stereotypes and signaling to officials that they represent one racial group rather than everyone — even without diluting anyone's vote.
- The Court concluded that United Jewish Organizations v. Carey, the main precedent the lower court relied on, addressed only vote-dilution claims and did not bar this newly recognized 'analytically distinct' claim about bizarre, race-based shapes.
- Applying this framework to District 12's extreme, snake-like shape spanning 160 miles with little regard for county or community lines, the Court found the allegations sufficient to state a claim that could trigger strict scrutiny on remand.

Cases affected by this decision
Distinguishes United Jewish Organizations of Williamsburgh, Inc. v. Carey (430 U.S. 144)
The Court said UJO only addressed vote-dilution claims and does not block this new type of bizarre-shape racial gerrymander claim.
Reaffirms Gomillion v. Lightfoot (364 U.S. 339)
The Court relied on Gomillion as supporting the idea that oddly drawn boundaries segregating voters by race can be challenged.
