Avery v. Midland County
The Supreme Court ruled that the one-person, one-vote rule it applied to state legislatures in Reynolds v. Sims also applies to local government bodies with broad, general powers, striking down Midland County, Texas's wildly unequal commissioner districts.
The decision extends constitutional equal-population requirements to tens of thousands of county, city, and town governing boards across the country, reshaping how local elections must be structured whenever a body has general governing authority over its whole area.
How it got here: A Texas trial court ruled for the voter under the state constitution; the Texas Court of Civil Appeals reversed; the Texas Supreme Court sided with the voter but rejected a strict population standard, and he sought review here.
The Case in Depth
What happened
A Midland County, Texas taxpayer and voter challenged how the county's five-member Commissioners Court was elected. Four commissioners were chosen from single-member districts with wildly unequal populations—one district held nearly the entire city of Midland with over 67,000 people, while three rural districts each had fewer than 900 residents. He argued this gave rural voters far more influence per person than urban voters.
The question before the Court
Does the Constitution require that a county's governing board be elected from districts with roughly equal populations, the same way state legislative districts must be?
The Court's answer
Yes — the Court ruled that the Fourteenth Amendment's equal protection guarantee extends the one-person, one-vote principle from state legislatures to local governments that hold general governing power over their entire area. Because Midland County's Commissioners Court set tax rates, built roads, ran welfare programs, and made budget decisions affecting every resident, it had to be elected from districts with substantially equal populations, just like a state legislature.
The Court rejected labeling the body as merely "administrative" to escape the rule, since most local governments mix legislative, executive, and judicial functions. It left open, however, whether local bodies with narrow, special-purpose functions affecting only some residents must follow the same strict population rule, reserving that question for a future case.

Why it matters
Millions of residents of counties, cities, and towns nationwide gained a constitutional guarantee that their vote for local governing boards carries roughly the same weight as their neighbors' votes. Local governments with broad powers—over budgets, taxes, roads, and welfare—now must redraw districts to reflect population, not historical or geographic boundaries that favored rural or established areas.
What changes now
The case was sent back for further proceedings consistent with the Court's ruling, meaning Midland County had to redraw its commissioner districts to comply with the equal-population requirement. This was a final merits decision establishing a nationwide constitutional rule for local governments with general powers, though the Court left open how the rule applies to special-purpose local bodies whose functions affect only some residents more than others.
What this does not decide
The Court expressly limited its holding to local governments with general powers over their entire area, and did not decide whether special-purpose units of government—those serving only a subset of constituents or a narrow function—must also be apportioned strictly by population.
Concurrences and dissents
Dissent — Justice Harlan
Justice Harlan argued the Court lacked jurisdiction because the Texas judgment rested on an adequate state constitutional ground and was not yet final. On the merits, he argued extending Reynolds v. Sims to roughly 80,000 local governments was unjustified because no 'practical necessity' like failed political correction existed at the local level, and that rigid population-based apportionment ignores the specialized, varied functions of local governments.
Dissent — Justice Fortas
“It is like insisting that each stockholder of a corporation have only one vote even though the stake of some may be $1 and the stake of others $1,000.”Fortas's analogy criticizing a rigid population-only rule for a county with specialized rural functions.
Justice Fortas would have dismissed the case as improvidently granted to let Texas complete its own redistricting first. On the merits, he argued equal protection should account for the reality that Midland County's Commissioners Court served mainly rural interests, so a rigid one-person-one-vote formula would flip the imbalance and silence rural voters who depend most on the county government.
Dissent — Justice Stewart
Justice Stewart joined Harlan and Fortas in believing the writ should be dismissed as improvidently granted, and largely agreed with Fortas's reasoning on the merits, except that he continued to reject the underlying doctrine of Reynolds v. Sims itself, believing legislative apportionment is too complex to be resolved by simple population arithmetic.
How the Court got there
The legal reasoning, step by step
- The Court started from Reynolds v. Sims, which held that the Equal Protection Clause requires state legislative districts to have substantially equal populations because every voter has a right to a ballot of equal weight.
- It reasoned that the Equal Protection Clause binds all exercises of state power, including power delegated to local governments, because cities and counties act as arms of the state when they govern.
- The Court rejected the argument that only bodies performing clearly 'legislative' functions must be equally apportioned, noting that Midland County's Commissioners Court blended legislative, executive, and judicial functions, like most American local governments, so labels alone could not decide the case.
- It found that because the Commissioners Court exercised broad, general governmental powers—setting tax rates, adopting budgets, building roads, running welfare programs—affecting all county residents regardless of where they lived, it counted as a general-purpose unit of local government subject to the equal-population rule.
- The Court distinguished this case from bodies with narrow, special-purpose functions that affect only a defined subset of constituents, reserving judgment on whether such special-purpose units must also be apportioned by population.
- Applying this rule, the Court concluded that Midland County's districts, with population disparities as extreme as 67,906 to 414 residents, could not be justified by non-population factors like land area or voter registration, so the districting scheme violated the Equal Protection Clause.
