Consider the two tests discussed by the Majority and the dissent in American Legion:
I. Justice Alito's Plurality Opinion: The Lemon test does not apply to the retention of "established, religiously expressive monuments. symbols, and practices." More Alito: "The passage of time gives rise to a strong presumption of constitutionality." p. 1804 & 1805.\
II. Justice Ginsburg's dissent: She applies the Lemon endorsement test and asserts that "a display of a religious symbol" is "presumed to endorse its religious content." p. 1810
Now consider Justice Kavanaugh's concurring opinion on p. 1807-1808:
"[T]he
Court today applies a history and tradition test in examining and
upholding the constitutionality of the Bladensburg Cross....And the
cases together lead to an overarching set of principles: If the
challenged government practice is not coercive and if it (i) is rooted
in history and tradition; or (ii) treats religious people,
organizations, speech, or activity equally to comparable secular
people, organizations, speech, or activity; or (iii) represents
a permissible legislative accommodation or exemption from a
generally applicable law, then there ordinarily is no Establishment
Clause violation. The practice of displaying religious
memorials, particularly religious war memorials, on public land
is not coercive and is rooted in history and tradition. The Bladensburg
Cross does not violate the Establishment Clause. . . ."
So, where does the opinion leave newer displays, ones that are not yet “established” by the passage of time?
How long is long?
What test applies to newer displays?
Suppose the City of Kearney erects a cross monument for local soldiers who died fighting in Iraq or Afghanistan?
Would Lemon apply?
Or some kind of historical traditions test that would uphold the types of displays existing throughout American history?
