to the inquiry. A textualist may acknowledge that
the common meaning of a term has changed over
time, but the historical antecedents of a phrase do
not control the inquiry, though they may inform it.
In short, the present-day, plain reading of the text
is paramount under this approach. The opinions
of Justice Hugo Black embody this approach in
cases such as Y
OUNGSTOWN SHEET & TUBE V. SAW-
YER, 343 U.S. 579 (1952), and Adamson v. People
of State of California, 332 U.S. 46 (1947).
History provides a second method of consti-
tutional interpretation. The historical method
focuses on the original understanding of a con-
stitutional provision as reflected in speeches or
writings surrounding the provision’s adoption.
The diffi culty with this approach to constitutional
interpretation is that in the absence of a clearer
record of what the framers of the Constitution or
persons voting to adopt it believed, it is diffi cult to
interpret authoritatively the Constitution based on
history alone. For this reason, courts often rely on
history to supplement or refute a particular read-
ing of the Constitution derived at through other
modes of interpretation.
Structural arguments are a third method of
constitutional interpretation. Structuralists derive
constitutional meaning from the structure of the
text and the relationship between particular tex-
tual provisions. The theories of separation of pow-
ers, which concerns the allocation of power among
the three branches of the federal government, and
federalism, which concerns the allocation of
power between federal and state governments—
neither of which is expressly mentioned in the text
of the Constitution—have been derived through
structural arguments. Professor Charles Black, Jr.,
a renowned professor of constitutional law, was
one of structuralism’s greatest champions. Two
criticisms of structuralism are, fi rst, the process
of inferring structural rules to be applied in par-
ticular cases is unprincipled, and second, structur-
alism cannot provide a fi rm basis for construing
personal rights but rather is better suited for con-
struing intergovernmental relationships.
Doctrinalism is the fourth method of consti-
tutional interpretation. Over time, courts hear
constitutional cases involving similar factual pat-
terns. In adjudicating these cases, courts develop
doctrines—rules, principles, and standards—that
govern future decisions pursuant to stare decisis,
or precedent (on how the court decided similar
cases in the past). Doctrinal arguments are most
prevalent in areas of constitutional law where
there is no strong textual foundation. In substan-
tive due process cases, for example, the Court
resolves controversies primarily by considering
precedent, as in cases like E
ISENSTADT V. BAIRD,
405 U.S. 438, 453 (1972). The principal criticism
of the doctrinal modality is that because the con-
stitutional text is itself authoritative, the Constitu-
tion does not authorize courts to convert the text
into judicial doctrines. Nevertheless, because the
Constitution speaks in broad terms, many think
that in order to apply the Constitution in a consis-
tent and transparent manner, courts must create
doctrines that govern future cases.
Prudentialism is the fi fth method. Under this
modality, courts consider policy consequences
in interpreting the Constitution. Prudentialism
is based on the premise that the Constitution is
a practical document, not merely an expression
of political philosophy. Justice Robert H. Jack-
son best expressed this premise in T
ERMINIELLO
V. CITY OF CHICAGO, 337 U.S. 1, 37 (1949), when
he claimed that the Constitution is not “a suicide
pact.” Accordingly, courts must consider the costs
and benefi ts of their constitutional decisions. Pru-
dentialism often gives rise to a highly pragmatic
and economic approach to constitutional interpre-
tation, such as the one endorsed by Judge Richard
Posner. While many worry about the broad dis-
cretion courts exercise in weighing costs and ben-
efi ts, prudentialism is nonetheless an oft-applied
modality that has long been part of constitutional
interpretation.
Ethics is the fi nal modality. Courts interpret
the Constitution under this modality by consult-
ing the cultural values expressed in the Constitu-
tion. The most fundamental constitutional value
is the notion that that the government has lim-
ited powers and that ultimate authority therefore
resides in the individual. Ethical arguments are
thus most common when interpreting the Tenth
Amendment, which guarantees states’ rights, and
constitutional interpretation 165
