Detroit Timber & Lumber Co., 200 U. S. 321, 337. SUPREME COURT OF THE UNITED STATES Syllabus ALEXANDER, PRESIDENT OF THE SOUTH CAROLINA SENATE, ET AL. v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP ET AL. APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF SOUTH CAROLINA No. 22–807. Argued October 11, 2023—Decided May 23, 2024 The Constitution entrusts state legislatures with the primary responsibility for drawing congressional districts, and legislative redistricting is an inescapably political enterprise. Claims that a map is unconstitutional because it was drawn to achieve a partisan end are not justiciable in federal court. By contrast, if a legislature gives race a predominant role in redistricting decisions, the resulting map is subjected to strict scrutiny and may be held unconstitutional. These doctrinal lines collide when race and partisan preference are highly correlated. This Court has endorsed two related propositions when navigating this tension. First, a party challenging a map’s constitutionality must disentangle race and politics to show that race was the legislature’s “predominant” motivating factor. Miller v. Johnson, 515 U. S. 900, 916. Second, the Court starts with a presumption that the legislature acted in good faith. To disentangle race from other permissible considerations, plaintiffs may employ some combination of direct and circumstantial evidence. Cooper v. Harris, 581 U. S. 285, 291. Where race and politics are highly correlated, a map that has been gerrymandered to achieve a partisan end can look very similar to a racially gerrymandered map. Thus, in Easley v. Cromartie, 532 U. S. 234, the Court held that the plaintiffs failed to meet the high bar for a racial-gerrymandering claim when they failed to produce an alternative map showing that a rational legislature sincerely driven by its professed partisan goals would have drawn a different map with greater racial balance. Id., at 258. Without an alternative map, the Court also found it difficult for plaintiffs to defeat the starting presumption that the legislature acted in good faith.
