Supreme Court May Reconsider 
Establishment Clause Jurisprudence in 
Challenge to Cross Display: Part One 
Updated February 12, 2019 
On February 27, i
n American Legion v. American Humanist Association, the Supreme Court is scheduled 
to hear oral argument on the constitutionality of a large cross that was erected as a war memorial in Prince 
George’s County, Maryland. Last year, the U.S. Court of Appeals for the Fourth Circuit (Fourth Circuit) 
held that the cross display violated the First Amendment’s Establishment Clause. The Supreme Court 
agreed to review this decision
, considering not only whether the memorial is unconstitutional, but also 
what test should govern this inquiry. The case thus presents the Court with the opportunity to clarify its 
Establishment Clause jurisprudence—an area of the law th
at scholars and
 judges alike routinely deride for 
lacking clear legal rules. It also offers the first significant opportunity for the newest members of the 
Court, Justices Gorsuch and Kavanaugh, to weigh in on this area of the law. 
This is a two-part Legal Sidebar. This first part briefly reviews existing jurisprudence, explaining the 
various tests that the Court has used to analyze Establishment Clause claims and ending with a focus on 
recent decisions considering the constitutionality of public monuments that contain religious symbols. 
Part Two focuses on 
American Legion, reviewing the lower court decision and the parties’ arguments 
before the Supreme Court. It then discusses ways the Court might resolve the case, as well as the 
significant implications the Court’s decision could have for Congress. 
Various Approaches to the Establishment Clause 
The Establishment Clause
 provides that the government “shall make no law respecting an establishment 
of religion.” This language most obviously prohibits the government from establishing an official national 
religion, and the Court has 
also long understood the Clause to prevent other government aid directed 
toward religion, as well. However, judges—and even th
e Framers of the Constitution—have debated the 
precise scope of this prohibition. While the Supreme Court has ofte
n referred to government “neutrality” 
toward religion as the guiding principle, this neutrality standard has itself been subject to
 divergent 
interpretations. Broadly speaking, scholars have identified two diametric views of the Establishment 
Clause: a separationist view and an accommodationist view. The Cou
rt has embraced both views, at 
various times.

Th
e separationist view stems from the idea that the Establishment 
Clause creates “a wall of separation 
between church and State.” This characterization of the Clause comes from
 Thomas Jefferson, whose 
work served as the basis for the First Amendment’s Religion Clauses. One example of this approach came 
in 
Everson v. Board of Education, decided in 1946, where the Cou
rt said that the government cannot “aid 
one religion, aid all religions, or prefer one religion over another.” However
, a number of
 Justices have 
argued against strict separationism, instead embracing a mor
e accommodationist approach. As Justice 
Kennedy
 said in a 1989 dissent, “[r]ather than requiring government to avoid any action that 
acknowledges or aids religion, the Establishment Clause permits government some latitude in recognizing 
and accommodating the central role religion plays in our society.” Thus, the Court has recognized that the 
Constitution does not “require complete separation of church and state; it affirmatively mandates 
accommodation, not merely tolerance, of all religions, and forbids hostility toward any.” 
The Supreme Court has adopted both separationist and accommodationist positions in its opinions on the 
Establishment Clause. For decades, the Court has applied what has becom
e known as the 
Lemon test—a 
test th
at can be described as separationist. I
n Lemon v. Kurtzman, decided in 1971, the Supreme Court 
outlined a three-part test: to be constitutional, (1) a government action “must have a secular legislative 
purpose;” (2) “its principal or primary effect must be one that neither advances nor inhibits religion;” and 
(3) it “must not foster an excessive government entanglement with religion.” In 
Lynch v. Donnelly, in a 
concurring opinion the Court 
later adopted, Justice O’Conno
r argued that the first and second prongs of 
the 
Lemon test are focused on government “endorsement” of religion: “The purpose prong of 
the 
Lemon test asks whether government’s actual purpose is to endorse or disapprove of religion. The 
effect prong asks whether, irrespective of government’s actual purpose, the practice under review in fact 
conveys a message of endorsement or disapproval.” In later opinions, Justice O’Conno
r clarified that 
courts should ask whether a “
reasonable observer would view a government practice as endorsing 
religion.” Scholars have said that this nonendorsement principle represents a
 more accommodationist test 
than the original articulation of 
Lemon, even if it is ultimately a relatively
 separationist position. 
But the Court h
as not always used the 
Lemon test, or the nonendorsement version of that test, to analyze 
disputed government actions. In particular, judges arguing for a more accommodationist view of the 
Establishment Clause have said that government support for religion should be considered constitutional 
if that government support is grounded in
 historical tradition. Thus, for example, when it considers the 
constitutionality of government-sponsored prayer at certain public events, the Court has primarily 
assessed such practices by reference to historical context, rather than the 
Lemon test, upholding prayers 
that fit within longstanding 
“tradition” and are 
“part of the fabric of our society” so long as the 
government is not
 coercing participation in religion or
 proselytizing. While he was a lower court judge, 
Justice Kavanaugh authored a con
curring opinion in which he analyzed an Establishment Clause claim 
involving “government-sponsored religious speech at” a “public event[]” by reference to “the Nation’s 
history and tradition.” Other Justices have embraced this historical view in broader contexts. For example, 
in a recent
 opinion dissenting from a denial of certiorari, Justice Thomas, joined by Justice Gorsuch, 
argued that the proper approach to evaluating Establishment Clause claims was to “focus on whether a 
government practice is supported by this country’s history and tradition.”  
In the past, Justices Thomas and Scalia took what may be an even more accommodationist view: looking 
to historical understandings of the Establishment Clause, they hav
e argued that the government violates 
that Clause only if it coerces “religious orthodoxy” or “financial support 
by force of law and threat of 
penalty.” Thus, Justice Thomas ha
s argued that “the Framers” understood “establishment” to refer only to 
legal coercion—which is distinct, in the views of Justices Scalia and Thomas, from the 
“psychological 
coercion” that they say the Court has sometimes found to violate the Establishment Clause.

Establishment Clause Evaluation of Religious Displays 
The Court’s divisions on the Establishment Clause have been especially apparent in cases evaluating the 
constitutionality of government monuments that contain religious symbols. Perhaps most notably, in 
2005, a majority of the Court in
 Van Orden v. Perry could not agree on a single rationale for rejecting a 
challenge to 
a Ten Commandments display on the grounds of the Texas State Capitol. The State Capitol 
grounds included other historical monuments, and the Ten Commandments display itself contained 
imagery besides the text of the commandments. In an opinion joined by three other Justices, Chief Justice 
Rehnqu
ist concluded that the 
Lemon test was “not useful in dealing with the sort of passive monument 
that Texas has erected on its Capitol grounds.” “Instead,” the plurality
 said, its decision to approve the 
display was “driven both by the nature of the monument and by our Nation’s history.” Justice Breyer 
provided the fifth vote to uphold the monument. In h
is concurrence, he expressed his belief that in the 
“fact-intensive” application of the Establishment Clause, there could be “no test-related substitute for the 
exercise of legal judgment.” In h
is view, the facts “surrounding the display’s placement on the capitol 
grounds and its physical setting,” along with the history of the public’s reception of that monument, 
suggested that the purpose and effect of the display were secular rather than religious. Justice Breyer also 
expressed concern that a “contrary conclusion” in that case would “exhibit a hostility toward religion” 
that could “create the very kind of religiously based divisiveness that the Establishment Clause seeks to 
avoid.” 
But in
 McCreary County v. ACLU, issued the same day as 
Van Orden, a majority of the Court (the 
Van 
Orden dissenters, joined by Justice Breyer) did apply 
Lemon to hold that a different Ten Commandments 
display—in which two counties posted stand-alone displays of the Ten Commandments on the walls of 
their courthouses—violated the Establishment Clause. In striking down the 
McCreary County displays, 
the Cou
rt emphasized that the “clearly religious” text of the Commandments “stood alone,” not as part of 
any secular display or “traditionally symbolic representation.” In addition, the Court believed that the 
circumstances surrounding the posting of the commandments and subsequent iterations of the displays 
emphasized the religious character of the display.  
Perhaps in light of the 
“mixed messages” the Supreme Court has sent, lower courts have resolved 
Establishment Clause challenges by attempting to draw factual analogies to previously decided cases 
rather than engaging in the more theoretical debate described above. Looking to prior cases in which the 
Supreme Court has reviewed public monum
ents, lower courts have applied the 
Lemon test while also 
following Justice Breyer’s opinion in 
Van Orden, viewing religious display inquiries as 
“context-specific 
and fact-intensive.”  
Roberts Court Era 
As described above, Justice O’Connor played a significant role in the modern debate over the meaning of 
the Establishment Clause. The Roberts Court has decided
 relatively few cases concerning the scope of the 
Establishment Clause since the retirement of Justice O’Connor in 2005, giving little insight into how the 
new Justices who have joined the Court since then view these issues. In one case interpreting the First 
Amendment’s Free Exercise Clause
, Trinity Lutheran Church of Columbia, Inc., v. Comer, Chief Justice 
Roberts wrote an opinion for the Court holding that a state policy excluding churches from a grant 
program impermissibly discriminated “against religious exercise.” Justice Sotomayor
 dissented from this 
opinion, joined by Justice Ginsburg, saying that in her view, it would violate the Establishment Clause for 
a state to “directly fund religious exercise.” 
Trinity Lutheran thus suggests that the Roberts Court may 
hold a more accommodationist view of the Religion Clauses as a whole. 
Likely the most significant Establishment Clause case decided in recent years w
as Town of Greece v. 
Galloway, in which the Court held that a town did not violate the Establishment Clause by opening its 
board meetings with a prayer. Justice Kennedy wrote the opinion of the Cour
t, assessing the practice’s

 constitutionality by referring to the “tradition” of prayers that the Court had previously upheld and by 
looking to historical practice. In a portion of his opinion that was joined only by Chief Justice Roberts and 
Justice Alito, Justice Kennedy
 also ruled that the prayers were not impermissibly coercive, again by 
looking to historical practice, saying that a “reasonable observer” would be “acquainted with this 
tradition” of legislative prayer and would understand that the purpose of the prayers was to acknowledge 
religion, not to proselytize.  
American Legion will present the Court with the opportunity to clarify whether the 
Lemon test 
remains good law, or whether instead lower courts should be analyzing more Establishment 
Clause claims under the “history and tradition” analysis followed in cases like 
Town of Greece. 
Part Two of this Sidebar discusses 
American Legion in more detail.
