ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE
OF THE NAACP
Opinion of the Court
assessing a legislature’s work, we start with a presumption
that the legislature acted in good faith.
In this case, which features a challenge to South Carolina’s redistricting efforts in the wake of the 2020 census,
the three-judge District Court paid only lip service to these
propositions. That misguided approach infected the District Court’s findings of fact, which were clearly erroneous
under the appropriate legal standard. We therefore reverse
the trial court in part and remand for further proceedings.

Redistricting constitutes a traditional domain of state
legislative authority. See Moore v. Harper, 600 U. S. 1
(2023); see also U. S. Const., Art. I, §4, cl. 1. The Fourteenth
Amendment introduces one constraint by prohibiting a
State from engaging in a racial gerrymander unless it can
satisfy strict scrutiny. But given “the complex interplay of
forces that enter a legislature’s redistricting calculus,” we
have repeatedly emphasized that federal courts must “exercise extraordinary caution in adjudicating claims that a
State has drawn district lines on the basis of race.” Miller
v. Johnson, 515 U. S. 900, 915–916 (1995). Such caution is
necessary because “[f]ederal-court review of districting legislation represents a serious intrusion on the most vital of
local functions.” Id., at 915. To untangle race from other
permissible considerations, we require the plaintiff to show
that race was the “predominant factor motivating the legislature’s decision to place a significant number of voters
within or without a particular district.” Id., at 916.
To make that showing, a plaintiff must prove that the
State “subordinated” race-neutral districting criteria such
as compactness, contiguity, and core preservation to “racial
considerations.” Ibid. Racial considerations predominate
when “[r]ace was the criterion that, in the State’s view,
