Louisiana v. Callais · ¶74

The same is true with respect to the drawing of districts to achieve partisan advantage. Disapproval of partisan gerrymandering dates back to the founding. See Rucho v. Common Cause, 588 U. S. 684, 696–697 (2019). But partisan gerrymandering claims are not justiciable in federal court. Id., at 718. “Federal judges have no license to reallocate political power between the two major political parties, with no plausible grant of authority in the Constitution, and no legal standards to limit and direct their decisions.” Ibid. Thus, in considering the constitutionality of a districting scheme, courts must treat partisan advantage like any other race-neutral aim: a constitutionally permissible criterion that States may rely on as desired.
