ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE
OF THE NAACP
KAGAN, J., dissenting
the “testimony of government officials,” proof about the
data available to mapmakers, and “expert analysis”—“[a]n
alternative map is merely an evidentiary tool.” Id., at 318–
319. So “neither [a map’s] presence nor its absence can itself resolve a racial gerrymandering claim.” Id., at 319.
The majority cannot evade Cooper’s force by casting today’s holding as an “adverse inference” rule rather than a
simple requirement. First, there is precious little difference
between the two. Given the apparent strength of the majority’s adverse inference, few litigants will feel free to proceed without commissioning alternative maps. The majority’s inference is effectively a requirement, whether or not
it goes by that label. And anyway, Cooper’s reasoning easily
encompasses—which is to say forbids—the majority’s new
inference rule. The point in Cooper was to treat maps
equivalently to—rather than “elevate” them above—other
forms of evidence. Id., at 318. So if the plaintiff ’s non-map
evidence supports a claim, the Court stated, the absence of
a map “does not matter.” Ibid. The Cooper dissent well
understood the point. No less than three times, the dissent
quoted the Court’s “does not matter” line, arguing vociferously that a map’s absence should matter, if not in all cases,
at least in all but “exceptional ones.” Id., at 336; see id., at
329, 359. The dissent lost that battle, but now succeeds in
overturning the essence of Cooper’s map ruling.
The majority-née-dissent’s reasons for elevating maps
above other evidence have not improved since Cooper held
to the contrary. The majority states that maps can serve as
a good way to undermine a State’s “it was all politics” defense. See ante, at 30–31. No argument there: The Cooper
Court also said as much. 581 U. S., at 317. But it went on
to say that maps “are hardly the only means” of attacking
such a defense—as this case well shows. Id., at 318; see
infra, at 15–33. The majority also insists that plaintiffs can
“easily churn out” alternative maps at “little marginal cost.”
Ante, at 30 (quoting, of course, the Cooper dissent). Maybe
