The map at the center of Shaw v. Reno was North Carolina’s 1992 congressional District 12: a roughly 160-mile ribbon that followed Interstate 85 across the middle of the state, in places no wider than the highway’s right-of-way. It linked Black neighborhoods in Durham, Greensboro, and Charlotte, cities otherwise far apart, by threading a narrow corridor between and around the communities in between. The Supreme Court’s 5-4 decision in 1993 held that a district drawn so irregularly it can only be explained as an effort to sort voters by race can be challenged under the Equal Protection Clause and must survive strict scrutiny.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
What District 12 Actually Looked Like
The district stretched about 160 miles along the I-85 corridor through north-central North Carolina. It was extraordinarily narrow. In several stretches its boundaries followed nothing but the interstate itself, so the district was no wider than the road. The lines bypassed surrounding neighborhoods to reach specific pockets of Black voters, stitching together urban areas that shared little in common geographically beyond the racial composition of the populations pulled into the district.
The state’s other new majority-Black district, District 1, sat in the northeastern corner of the state and drew less attention for its shape. District 12 was the one that became, in the majority’s phrase, one of the most recognizable maps in modern redistricting litigation.
Why the Map Was Drawn That Way
North Carolina gained a twelfth congressional seat after the 1990 census. Because parts of the state were covered under Section 5 of the Voting Rights Act, any redistricting plan had to go to the U.S. Attorney General for preclearance. The state first submitted a plan with a single majority-Black district. The Attorney General’s office rejected it and suggested a second majority-Black district could be drawn to reflect minority voting strength in the south-central to southeastern part of the state.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
Legislators went back and produced a revised map with two majority-Black districts. But rather than putting the second one where the Justice Department had pointed, they created District 12 along the I-85 corridor in the north-central part of the state, connecting Black neighborhoods in Durham, Greensboro, and Charlotte.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
Why the Shape Mattered Legally
Redistricting has long followed a set of traditional criteria: compactness, contiguity, respect for existing political boundaries like counties and cities, and preservation of communities with genuine common interests.2Constitution Annotated. Amdt14.S1.8.6.6 Racial Vote Dilution and Racial Gerrymandering
District 12 broke almost all of them. A 160-mile corridor is not compact. Slicing through multiple counties to reach specific neighborhoods does not respect political subdivisions. The one factor that consistently explained where the boundary went, and where it did not, was the racial composition of the voters on each side of the line. When a district abandons every traditional criterion and race is the only variable that fits the map, it becomes vulnerable to constitutional attack.
The Lawsuit and What the Plaintiffs Argued
Ruth Shaw and four other North Carolina voters sued, arguing that the map was an unconstitutional racial gerrymander under the Equal Protection Clause of the Fourteenth Amendment. The case carried Janet Reno’s name because she was Attorney General when it reached the Supreme Court, though the original preclearance objection had come from the Justice Department under the prior administration.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
The plaintiffs’ theory was new. They did not claim their votes had been diluted or that they had been prevented from electing candidates of their choice. They argued that a district so bizarrely drawn it could only be understood as racial sorting sends a message that all voters of the same race think alike and share the same political interests. Grouping people by skin color, they said, reinforces a racial stereotype the government has no business endorsing.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
A three-judge district court dismissed the case for failure to state a claim. The plaintiffs appealed directly to the Supreme Court.
What the Supreme Court Held
Justice Sandra Day O’Connor wrote the majority opinion, joined by Chief Justice Rehnquist and Justices Scalia, Kennedy, and Thomas. The Court held that the plaintiffs had stated a valid Equal Protection claim by alleging that the plan was “so irrational on its face that it can be understood only as an effort to segregate voters into separate districts on the basis of race.”1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
Grouping voters of the same race despite their being separated by vast distances and political boundaries, the majority wrote, “bears an uncomfortable resemblance to political apartheid.” It reinforces the assumption that members of a racial group think alike regardless of education, income, or where they live. The Court also warned that legislators elected from a district drawn around one racial group’s perceived interests may come to see themselves as representing only that group.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
The ruling did not strike down District 12. It established a rule: a redistricting plan so irregular on its face that it can only be explained by race must survive strict scrutiny. The state has to prove the district serves a compelling governmental interest and is narrowly tailored to that interest. The case went back to the lower court to apply that test.
The Dissent
Justice White, writing for himself and Justices Blackmun and Stevens, argued the plaintiffs had suffered no real injury. White voters still made up the majority in 10 of North Carolina’s 12 districts. No one had been denied the vote, and no group’s political influence had been reduced. In his view, the majority had built a constitutional claim out of a district’s appearance without any showing of actual harm. Justice Souter argued that without proof of vote dilution the case should not have gone forward. The split reflected a real divide: the majority treated racial sorting itself as the constitutional injury, while the dissenters held that the Constitution reaches redistricting only when it actually weakens a group’s political power.1Justia U.S. Supreme Court Center. Shaw v. Reno, 509 U.S. 630 (1993)
What Happened to the Map
On remand, the lower court upheld the 1992 map, finding North Carolina had a compelling interest in complying with the Voting Rights Act. The Supreme Court reversed in Shaw v. Hunt (1996), rejecting both of the state’s justifications. Creating an additional majority-Black district was not actually required by Section 5. And the district could not remedy a potential Section 2 violation, because Section 2 requires the minority group to be geographically compact, and a 160-mile corridor along a highway is not compact.3Legal Information Institute. Shaw v. Hunt, 517 U.S. 899 (1996)
North Carolina redrew the map. Its 1997 plan kept a reconfigured District 12 with boundaries the legislature said were driven by partisan politics rather than race. That triggered more litigation. In Easley v. Cromartie (2001), the Supreme Court upheld the redrawn district 5-4, holding that the challengers had not proved race rather than political affiliation was the dominant factor. Because race and party registration correlate closely in North Carolina, challengers had to show the legislature could have hit its political targets through an alternative map with significantly greater racial balance.4Justia U.S. Supreme Court Center. Easley v. Cromartie, 532 U.S. 234 (2001)
How the Standard Developed After Shaw
The Shaw opinion leaned heavily on how District 12 looked, which raised an obvious question: does a district have to appear bizarre to be challenged? Two years later, in Miller v. Johnson (1995), the Court answered no. Shape is useful circumstantial evidence, but challengers are “neither confined in their proof to evidence regarding a district’s geometry and makeup nor required to make a threshold showing of bizarreness.”5Justia U.S. Supreme Court Center. Miller v. Johnson, 515 U.S. 900 (1995)
What matters is whether race was the “predominant factor” motivating the legislature’s line-drawing. A challenger has to show the legislature subordinated traditional race-neutral criteria, such as compactness, contiguity, and respect for political subdivisions, to racial considerations. Meet that burden, and strict scrutiny applies.5Justia U.S. Supreme Court Center. Miller v. Johnson, 515 U.S. 900 (1995)
Mapmakers are left with a narrow path. The Voting Rights Act requires them to consider race to avoid diluting minority voting power. The Equal Protection Clause limits how much they can rely on it. Ignore race entirely and a state risks violating the VRA; let race drive the design and the state risks a Shaw-style challenge.2Constitution Annotated. Amdt14.S1.8.6.6 Racial Vote Dilution and Racial Gerrymandering
North Carolina’s District 12 returned to the Supreme Court once more. In Cooper v. Harris (2017), the Court held that race was the predominant factor in the design of both the 1st and 12th congressional districts in the state’s 2011 map. It rejected the argument that the districts had been drawn for partisan advantage rather than racial reasons, finding the evidence supported the lower court’s conclusion that race drove the lines. The Court also clarified that a state cannot escape a racial gerrymandering finding by claiming its ultimate goal was partisan. If the legislature actually used race as the mechanism to sort voters, a partisan objective does not launder the racial method.6Justia U.S. Supreme Court Center. Cooper v. Harris, 581 U.S. ___ (2017)
The 1992 map is gone. The rule it produced governs every redistricting cycle, in every state, whenever legislatures sit down to draw new lines.
