right, empowering citizens to partake in the pro-
cess of self-government.
Pioneering this principle in an 8-1 decision
in Gray v. Sanders, 372 U.S. 368 (1963), the
Supreme Court assuredly equated the concept of
political equality to one person, one vote. The case
involved Georgia’s notorious county unit system
of nominating candidates to statewide offi ces in
which each county was assigned a unit vote that
had little relation to its population. Invalidating
Georgia’s congressional districts on the grounds
of population inequality, the Court declared that
“[t]he conception of political equality from the
Declaration of Independence, to Lincoln’s
Gettysburg Address, to the Fifteenth, Seven-
teenth, and Nineteenth Amendments can
mean only one thing—one person, one vote.” Said
the Court, “Once the geographical unit for which
a representative is to be chosen is designated, all
who participate in the election are to have an equal
vote—whatever their race, whatever their sex,
whatever their occupation, whatever their income,
and wherever their home may be in the geographi-
cal unit. This is required by the Equal Protection
Clause of the Fourteenth Amendment.” While
the case dealt with the weight of a person’s vote
within a previously designated geographical unit,
the principle of “one person, one vote” announced
would later be extended to subsequent cases exam-
ining constitutional challenges of congressional
redistricting (Wesberry, 1964) and congressional
and state legislative redistricting (Reynolds, 1964).
In these two cases, the Court established defi ni-
tively that the United States Constitution imposed
a fundamental requirement on those charged with
congressional and state legislative redistricting to
approximate their population as “practicable” or
make them as “substantially” equal relative to the
population as possible.
Wesberry v. Sanders, 376 U.S. 1 (1964), was
the next case in the Court’s development of the
one person, one vote criterion. It involved a con-
gressional redistricting in the state of Georgia.
Citing the principle articulated a year before in
Gray as authority in a 6-3 decision, the Court
ordered that districts in Georgia be redrawn more
evenly. Holding that gross disparities in Georgia’s
congressional districts were a violation of the U.S.
Constitution, the Court concluded that “Article I,
Section 2 of the Constitution requires that rep-
resentatives shall be chosen by the people of the
several states” and be “apportioned among the
several States . . . according to their respective
Numbers.” Although in this case the Court recog-
nized the impossibility of drawing congressional
districts with mathematical precision, its dictum
revealed the expectation that “as nearly as is prac-
ticable one man’s vote in a congressional election
is to be worth as much as another’s.” Emphasiz-
ing the importance for a universally fair system of
election that incorporates the respect due and the
responsibilities owed to each citizen, the Court
observed further that “no right is more precious
in a free country than that of having a voice in the
election of those who make the laws under which,
as good citizens, we must live.” Other rights, even
the most basic, the Court added, “are illusory if
the right to vote is undermined.”
In Reynolds v. Sims (1964), a related case
decided four months after Wesberry but this time
focusing on state legislative districts alone, the
Supreme Court held that both houses of a state
legislature must be apportioned on the basis of
population equality and that “population” will
hence be the controlling factor in the construc-
tion of legislative districts. Upholding a lower
court decision invalidating Alabama’s legislative
apportionment, the Court observed that the equal
protection clause of the Fourteenth Amendment
requires that a state make an honest and good-
faith effort to construct districts, in both houses
of its legislature, as nearly equal in population as is
practicable. Put differently, the apportionment of
seats and boundary for legislative districts for both
houses of state legislatures had to be arranged so
that the number of inhabitants per legislator in
any one district is substantially equal or roughly
equal to the number of inhabitants per legislator
in any other district in the same state. Indeed, in
Baker v. Carr (1960), a case that in hindsight set
the stage for the development of the concept of
one person, one vote, the Supreme Court also held
that issues relative to state legislative apportion-
ment were appropriate for judicial review.
