BAKER v. CARR. 186 189' Opinion of the Court. periods of making the enumeration, be apportioned among the several counties or districts, according to the number of qualified voters in each; and shall not exceed seventy-five, until the population of the State ,shall be one million and a half, and shall never exceed ninety-nine; Provided, that any county having twothirds of the ratio shall be entitled to one member. "Sec. 6. Apportionment of senators.-The number of Senators shall, at the several periods of making the enumeration, be apportioned among the several counties or districts according to the number of qualified electors in each, and shall not exceed one-third the number of representatives. In apportioning the Senators among the different counties, the fraction that may be lost by any county or counties, in the apportionment of members to the House of Representatives, shall be made up to such county or counties in the Senate, as near as may be practicable. When a district is composed of two or more counties, they shall be adjoining; and no county shall be divided in forming a district." Thus, Tennessee's standard for allocating legislative representation among her counties is the total number of qualified voters resident in the respective counties, subject only to minor qualifications.' Decennial reapportionment 4 A county having less than, but at least two-thirds of, the population required to choose a Representative is allocated one Representative. See also Tenn. Const., Art. II, § 6. A common and much more substantial departure from the number-of-voters or total-population standard is the guaranty of at least one seat to each county. See, e. g., Kansas Const., Art. 2, § 2; N. J. Const., Art. 4, § 3, 1. While the Tennessee Constitution speaks of the number of "qualified voters," the exhibits attached to the complaint use figures based on the number of persons 21 years of age and over. This basis seems to have been employed by the General Assembly in apportioning legislative seats from the outset. The 1870 statute providing for the first enumeration, Acts of 1870 (1st Sess.), c. 107, directed the courts of

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.
