Issue

Does the one-person-one-vote principle of the Equal Protection Clause require states to use voter-eligible population rather than total population when apportioning state legislative districts?

Held

No. The Constitution does not require states to use voter-eligible population as the basis for drawing legislative districts; using total population is permissible and consistent with historical practice and the principle of representative equality.

Exam use

Students should cite Evenwel to argue that a state's choice of total population for redistricting is constitutional. Distinguish cases where a plaintiff argues for voter-eligible population or where a state uses a bizarre or arbitrary base. The case also illustrates the principle that the Court defers to legislative choices regarding the mechanics of representation, as long as there is a rational basis.

Summary

The Supreme Court upheld Texas's use of total population, rather than eligible voters, as the basis for drawing state legislative districts, rejecting a challenge that this violated the one-person-one-vote principle because it diluted votes in districts with higher citizen-voting-age populations. The Court held that states may use total population to ensure equal representation of all residents.

Facts

Texas drew state Senate districts using total population data from the 2010 Census. Appellants, voters in districts with high total populations and relatively low citizen-voting-age populations (meaning fewer eligible voters per representative), argued that this method inflated their voting power compared to voters in districts with low total populations and high CVAP. They claimed Texas should have used a voter-eligible population measure to comply with the one-person-one-vote requirement of the Equal Protection Clause.

Procedural History

A three-judge district court dismissed the complaint, holding that states have discretion to use total population for redistricting. The Supreme Court noted probable jurisdiction and affirmed.

Issue

Does the one-person-one-vote principle of the Equal Protection Clause require states to use voter-eligible population rather than total population when apportioning state legislative districts?

Held

No. The Constitution does not require states to use voter-eligible population as the basis for drawing legislative districts; using total population is permissible and consistent with historical practice and the principle of representative equality.

Ratio Decidendi

The one-person-one-vote principle, derived from Reynolds v. Sims, mandates that legislative districts be substantially equal in population. However, the Constitution leaves states discretion to choose the population base that best reflects their understanding of representation. Total population is a legitimate measure because it ensures that each resident, including non-voters (e.g., children, non-citizens, felons disenfranchised), receives representation in the legislature. The history of apportionment in the United States has consistently used total population, and nothing in the Equal Protection Clause dictates a different rule.

Obiter Dicta

Justice Thomas, concurring, argued that the one-person-one-vote doctrine itself is not constitutionally required and should be reconsidered. Justice Alito, concurring, noted that other measures, such as eligible voters, might be permissible in some circumstances, but states are not required to use them.

Reasoning

The Court emphasized that the text of the Fourteenth Amendment apportions Representatives among the states based on the 'whole number of persons in each state.' Although this applies to federal elections, it informs the understanding of representation in a democratic republic. The Court cited historical evidence that the Framers, the Reconstruction Congress, and states throughout U.S. history have consistently used total population for apportionment. It reasoned that representatives serve all their constituents, not just those who vote, and that using total population ensures that all persons receive 'the benefits of governmental services and representation.' The Court contrasted this with the difficulty of measuring voter-eligible population accurately and the risk of disenfranchising residents who are legally present but not eligible to vote. It concluded that the Constitution grants states flexibility, and total population is a reasonable choice.

Plain-English Explanation

The one-person-one-vote rule says that each person's vote should have equal weight. But who counts as a 'person' when drawing district lines? Some argued that only eligible voters should count, so that each district has the same number of voters. Others, including Texas, counted everyone living in a district—including children, non-citizens, and people who cannot vote. The Supreme Court said both approaches are allowed, but states do not have to use voter-eligible population. The reason is that representatives serve all their constituents, not just voters, and counting everyone ensures that all residents get equal representation for community services and lobbying their representative. This decision preserved the traditional method used since the founding, and it gives states flexibility.

Version 1 of 4

Reference to Evenwel v. Abbott (578 U.S. 54 (2016)) strengthens a Law of Democracy answer because the case reflects the principle that The one-person-one-vote principle, derived from Reynolds v. Sims, mandates that legislative districts be substantially equal in population. However, the Constitution leaves states discretion to choose the population base that best reflects their understanding of representation. Total population is a legitimate measure because it ensures that each resident, including non-voters (e.g., children, non-citizens, felons disenfranchised), receives representation in the legislature. The history of apportionment in the United States has consistently used total population, and nothing in the Equal Protection Clause dictates a different rule. Applied to a problem question, the case should be used after identifying the issue as Does the one-person-one-vote principle of the Equal Protection Clause require states to use voter-eligible population rather than total population when apportioning state legislative districts? 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
  • representative government

Precedents Applied

  • Reynolds v. Sims (377 U.S. 533) – established one-person-one-vote for state legislatures
  • Burns v. Richardson (384 U.S. 73) – allowed Hawaii to use registered voters for redistricting in the 1960s

Later Treatment

  • Abbott v. Perez (585 U.S. ___ (2018)) – applied Evenwel in a racial gerrymandering context

Key Passages

  • Non-voters count as persons for purposes of the one-person-one-vote principle. Representatives serve all residents, not just those who are eligible to vote.

Significance

Evenwel settled a major dispute about the meaning of one-person-one-vote for state and local redistricting. It affirms that states and localities may use total population as the basis for drawing districts, preserving the traditional method. This decision is important because it allows representation to include all residents, which protects communities with large numbers of non-voters. For exam use, students should understand that Equal Protection does not require voter-eligible population; total population is permissible, but the court left open the possibility that other bases might also be constitutional if used consistently.

Exam Tips

Students should cite Evenwel to argue that a state's choice of total population for redistricting is constitutional. Distinguish cases where a plaintiff argues for voter-eligible population or where a state uses a bizarre or arbitrary base. The case also illustrates the principle that the Court defers to legislative choices regarding the mechanics of representation, as long as there is a rational basis.

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 asks whether a state must use citizen voting-age population to draw districts, cite Evenwel to argue that total population is permissible. However, note that the Court did not say other bases are required, so a challenge to total population fails. Use Evenwel defensively for a state that uses total population, and offensively against a claim that the state must use a different metric.

Common Pitfalls

  • Assuming Evenwel requires total population (it only permits it).
  • Confusing Evenwel with the one-person-one-vote requirement for federal congressional districts (which still requires strict population equality).
  • Overlooking the state discretion rationale.
