I thought I remembered a Kossack who was part of this lawsuit?
The Supreme Court in a 5-4 decision has determined that if a gov't body makes a "good faith effort" at "inclusion", opening prayers are allowed even if they have a Christian (or I suppose other specific faith) slant.
From the decision
Respondents’ insistence on nonsectarian prayer is not consistent with this tradition. The prayers in Marsh were consistent with the First Amendment not because they espoused only a generic theism but because the Nation’s history and tradition have shown that prayer in this limited context could “coexis[t] with the principles of disestablishment and religious freedom.” 463 U. S., at 786. DiBoth opinions can be found here.
But just for that reason, the not-so-implicit message of
the majority’s opinion—“What’s the big deal, anyway?”—is
mistaken. The content of Greece’s prayers is a big deal, to Christians and non-Christians alike. A person’s response to the doctrine, language, and imagery contained in those invocations reveals a core aspect of identity—who that
person is and how she faces the world. And the responses of different individuals, in Greece and across this country, of course vary. Contrary to the majority’s apparent view, such sectarian prayers are not “part of our expressive idiom” or “part of our heritage and tradition,” assuming the word “our” refers to all Americans. Ante, at 19. They express beliefs that are fundamental to some, foreign to others—and because that is so they carry the ever-present potential to both exclude and divide. The majority, I think, assesses too lightly the significance of these religious differences, and so fears too little the “religiously based divisiveness that the Establishment Clause seeks to avoid.” Van Orden v. Perry, 545 U. S. 677, 704 (2005) (BREYER, J., concurring in judgment).
I would treat more seriously the multiplicity of Americans’ religious commitments, along with the challenge they can pose to the project—the distinctively American project—of creating one from the many, and governing all as united.
