Issue

Whether the Equal Protection Clause requires that seats in both houses of a bicameral state legislature be apportioned on a population basis.

Held

Yes. The Equal Protection Clause requires that both houses of a state legislature be apportioned substantially on a population basis, ensuring that each person's vote carries equal weight.

Exam use

When a problem question involves state legislative districts with unequal populations, cite Reynolds for the one person, one vote standard. Note that the standard applies to both houses of a state legislature. For congressional districts, use Wesberry v. Sanders. Be aware that minor deviations (under 10%) are presumptively constitutional, but larger deviations require strict scrutiny. Discuss the rational basis for any deviation.

Summary

The Supreme Court held that the Equal Protection Clause requires state legislative districts to be apportioned on a population basis, establishing the 'one person, one vote' principle. Both houses of a bicameral state legislature must be apportioned substantially equally by population, rejecting the federal analogy for state legislatures.

Facts

Alabama had not reapportioned its state legislature since 1901, leading to severe population disparities. For example, a rural district with 6,700 residents had the same representation as an urban district with 634,000 residents. Plaintiffs, including B.A. Reynolds, sued, arguing that the malapportionment violated the Equal Protection Clause.

Procedural History

A three-judge district court held the apportionment unconstitutional and ordered reapportionment. The Supreme Court affirmed, establishing the one person, one vote standard.

Issue

Whether the Equal Protection Clause requires that seats in both houses of a bicameral state legislature be apportioned on a population basis.

Held

Yes. The Equal Protection Clause requires that both houses of a state legislature be apportioned substantially on a population basis, ensuring that each person's vote carries equal weight.

Ratio Decidendi

The fundamental principle of representative government is equal representation for equal numbers of people. The federal analogy (Senate based on states, House on population) does not apply to state legislatures because the Constitution does not require states to mirror the federal structure. Deviations from population equality must be justified by a rational state policy, but the burden is on the state to show that the deviation is necessary to achieve a legitimate goal.

Obiter Dicta

Justice Harlan dissented, arguing that the Equal Protection Clause was not intended to mandate population-based apportionment and that the Court was usurping legislative function.

Reasoning

The Court reasoned that the right to vote is fundamental and that any dilution of that right through malapportionment violates equal protection. It rejected the argument that states could model one house on geography (like the U.S. Senate), because the Constitution does not impose the federal model on states. The Court held that 'legislators represent people, not trees or acres.' It established that population must be the controlling criterion for both houses, though minor deviations may be permissible if based on rational state policy (e.g., respecting political subdivisions). The Court emphasized that the Equal Protection Clause requires that each citizen have an equally effective voice in the election of state legislators.

Plain-English Explanation

This case said that when states draw districts for their legislatures, each district must have roughly the same number of people. Otherwise, some people's votes count more than others. For example, if one district has 10,000 people and another has 100,000, the person in the smaller district has more power. The Court said that is unfair and violates the Constitution.

Version 1 of 4

Reference to Reynolds v. Sims (377 U.S. 533 (1964)) strengthens a Law of Democracy answer because the case reflects the principle that The fundamental principle of representative government is equal representation for equal numbers of people. The federal analogy (Senate based on states, House on population) does not apply to state legislatures because the Constitution does not require states to mirror the federal structure. Deviations from population equality must be justified by a rational state policy, but the burden is on the state to show that the deviation is necessary to achieve a legitimate goal. Applied to a problem question, the case should be used after identifying the issue as Whether the Equal Protection Clause requires that seats in both houses of a bicameral state legislature be apportioned on a population basis. The stronger essay move is to connect the material facts to the court's holding, then explain whether the present facts support the same conclusion or justify distinguishing the authority.

Underlying Concepts

  • one person one vote
  • equal protection
  • apportionment
  • vote dilution
  • justiciability

Precedents Applied

  • Baker v. Carr (1962) – apportionment claims justiciable
  • Wesberry v. Sanders (1964) – one person one vote for Congress

Later Treatment

  • Evenwel v. Abbott (2016) – states may use total population for districting
  • Harris v. Arizona Independent Redistricting Commission (2016) – minor deviations allowed

Key Passages

  • Legislators represent people, not trees or acres. Legislators are elected by voters, not farms or cities or economic interests.

Significance

Reynolds v. Sims is a cornerstone of voting rights law, establishing the one person, one vote principle for state legislatures. It led to widespread reapportionment across the United States, shifting power from rural to urban areas. The case is essential for understanding equal protection in voting, the justiciability of apportionment claims (following Baker v. Carr), and the limits of state discretion in districting. Students should apply it to any challenge involving population disparities in legislative districts.

Exam Tips

When a problem question involves state legislative districts with unequal populations, cite Reynolds for the one person, one vote standard. Note that the standard applies to both houses of a state legislature. For congressional districts, use Wesberry v. Sanders. Be aware that minor deviations (under 10%) are presumptively constitutional, but larger deviations require strict scrutiny. Discuss the rational basis for any deviation.

Revision Checklist

  • Name the issue before discussing facts so the marker sees the legal question immediately.
  • State the holding in one sentence, then use the ratio to explain why the court reached that result.
  • Use the citation and jurisdiction to show why this authority matters for the problem you are answering.
  • Pair this case with one supporting or contrasting authority if the question tests limits, policy, or exceptions.

Problem Question Use

If a problem question describes a state with districts of vastly different populations, use Reynolds to argue that the plan violates equal protection. Calculate the maximum deviation and discuss whether it is justified by a rational state policy (e.g., preserving county boundaries). For congressional districts, apply Wesberry instead.

Common Pitfalls

  • Applying the federal analogy to state legislatures
  • Assuming any population deviation is unconstitutional
  • Confusing Reynolds with cases on racial gerrymandering
