In Reynolds v. Sims, 377 U.S. 533 (1964), this Court held that the Equal Protection Clause of the Fourteenth Amendment includes a "one-person, one-vote" principle. This principle requires that, "when members of an elected body are chosen from separate districts, each district must be established on a basis that will insure, as far as is practicable, that equal numbers of voters can vote for proportionally equal numbers of officials." Hadley v. Junior Coll. Dist. Of Metro. Kansas City, Mo., 397 U.S. 50, 56 (1970). In 2013, the Texas Legislature enacted a State Senate map creating districts that, while roughly equal in terms of total population, grossly malapportioned voters. Appellants, who live in Senate districts significantly overpopulated with voters, brought a one-person, one--vote challenge, which the three-judge district court below dismissed for failure to state a claim. The district court held that Appellants' constitutional challenge is a judicially unreviewable political question. The question presented is whether the "one-person, one-vote" principle of the Fourteenth Amendment creates a judicially enforceable right ensuring that the districting process does not deny voters an equal vote.
