BAKER v. CARR. 186 Opinion of the Court. An unbroken line of our precedents sustains the federal courts' jurisdiction of the subject matter of federal constitutional claims of this nature. The first cases involved the redistricting of States for the purpose of electing Representatives to the Federal Congress. When the Ohio Supreme Court sustained Ohio legislation against an attack for repugnancy to Art. I, § 4, of the Federal Constitution, we affirmed on the merits and expressly refused to dismiss for want of jurisdiction "In view . . . of the subject-matter of the controversy and the Federal characteristics which inhere in it . . . ." 'Ohio ex rel. Davis v. Hildebrant, 241 U. S. 565, 570. When the Minnesota Supreme Court affirmed the dismissal of a suit to .enjoin the Secretary of State of Minnesota from acting under Minnesota redistricting legislation, we reviewed the constitutional merits of the legislation and reversed the State Supreme Court. Smiley v. .Holm, 285 U. S. 355. And see companion cases from the New York Court of Appeals and the Missouri Supreme Court, Koenig v. Flynn, 285 U. S. 375; Carroll v. Becker, 285 U. S. 380. When a three-judge District Court, exercising jurisdiction under the predecessor of 28 U. S. C. § 1343 (3), permanently enjoined officers of the State of Mississippi from conducting an election of Representatives under a Mississippi redistricting act, -we reviewed the federal questions on the merits and reversed the District Court. Wood v. Broom, 287 U. S. 1, reversing 1 F. Supp. 134. A similar decree of a District Court, exercising jurisdiction under the same statute, concerning a Kentucky redistricting act, was Amendment.

Baker v. Carr

Judgment

Question Presented: Whether a claim alleging that a state's legislative apportionment scheme violates the Equal Protection Clause of the Fourteenth Amendment — by diluting the voting power of citizens in overpopulated districts — presents a justiciable controversy or is a non-justiciable "political question" that federal courts lack authority to adjudicate. This issue required the Court to revisit and overturn the precedent of Colegrove v. Green, 328 U.S. 549 (1946), which had held that federal courts should not intervene in reapportionment disputes.

Alleged Acts: Tennessee had not reapportioned its state legislative districts since 1901, despite a constitutional requirement to do so every ten years and despite dramatic population shifts over the intervening decades. By the 1960s, the state's legislative districts were severely malapportioned: some districts had populations over ten times larger than others, meaning rural voters were vastly overrepresented while urban voters were underrepresented. For example, a voter in a rural district had roughly ten times the voting power of a voter in an urban district like Memphis or Nashville. A group of Tennessee voters, led by Charles Baker (a Republican voter from Shelby County), sued Joe Carr, the Tennessee Secretary of State, in federal court. Baker alleged that the failure to reapportion violated the Equal Protection Clause of the Fourteenth Amendment by diluting the votes of urban residents. The suit sought to have the apportionment declared unconstitutional and to compel the state to reapportion.

Procedural history: The district court dismissed the complaint, holding that reapportionment was a non-justiciable political question beyond the authority of federal courts.

Summary: Baker v. Carr is one of the most consequential constitutional law decisions of the twentieth century. The Supreme Court held for the first time that challenges to state legislative apportionment under the Equal Protection Clause are justiciable — they do not present non-justiciable political questions. By ruling that federal courts have the authority to review and remedy malapportionment, the Court overturned the prior precedent of Colegrove v. Green (1946) and opened the door to the "reapportionment revolution" of the 1960s. The decision established that the Equal Protection Clause provides judicially manageable standards for evaluating vote dilution claims, and that voters whose votes are diluted by malapportioned districts have standing to sue. The case laid the constitutional foundation for the "one person, one vote" doctrine, which was formally articulated two years later in Reynolds v. Sims (1964). Together, Baker and Reynolds transformed American democracy by requiring legislative districts to be drawn based on substantially equal population, ending the rural-dominated legislatures that had persisted for decades despite massive urban population growth.

Conclusion: In a 6–2 decision, the Supreme Court reversed the district court's dismissal and held that legislative apportionment challenges under the Equal Protection Clause are justiciable — they do not present non-justiciable political questions. The Court held that the Equal Protection Clause provides a judicially manageable standard for evaluating apportionment claims, distinguishing them from cases involving the Guaranty Clause (Article IV, § 4), which had been held non-justiciable in Luther v. Borden. The Court explained that unlike the Guaranty Clause — which involves questions of republican government that lack judicially manageable standards — Equal Protection claims are governed by familiar and well-developed legal standards. The Court identified six characteristics of political questions (textual commitment to another branch, lack of judicially manageable standards, inability to decide without a policy determination, etc.) and concluded that none applied to Equal Protection apportionment claims. The Court emphasized that the claim was not based on the Guaranty Clause but on the Fourteenth Amendment, which provides an independent constitutional basis for judicial review.
