Thornburg v. Gingles (1986)
June 1986What Happened
The Supreme Court interpreted the 1982 Section 2 amendments and laid out a three-part test for vote dilution claims: a minority group must be sufficiently large and compact to form a majority in a district, be politically cohesive, and face white bloc voting that usually defeats its preferred candidates. The case involved North Carolina state legislative districts.
Outcome
Six of seven challenged North Carolina districts were struck down. Plaintiffs across the South began winning Section 2 cases against multimember districts and at-large elections.
The Gingles framework became the workhorse standard for forty years of vote dilution litigation, including Allen v. Milligan and the Mississippi judicial districts case.
Why It's Relevant Today
Callais directly questions whether the Gingles framework, and the race-conscious remedies it implies, can survive under the Fourteenth and Fifteenth Amendments.
