Shurtleff v. Boston
The Supreme Court ruled unanimously that Boston violated the First Amendment by refusing to let a religious group fly a Christian flag on a City Hall flagpole while freely allowing secular groups to use the same pole for their own flags.
The decision establishes that when governments open programs or public spaces to a broad range of private speakers without actively controlling the messages those speakers convey, they cannot single out religious voices for exclusion.
How it got here: A federal district court ruled for Boston; the First Circuit affirmed; Shurtleff and Camp Constitution asked the Supreme Court to hear the case, and it agreed.
The Case in Depth
What happened
Harold Shurtleff, director of a group called Camp Constitution, asked Boston for permission to fly a "Christian flag" on a City Hall Plaza flagpole during a public ceremony. Since at least 2005, Boston had routinely approved roughly 284 similar ceremonies for about 50 different private groups, allowing them to fly flags representing other countries, a gay pride celebration, a community bank, and more. A city official refused the Christian flag application, believing it would violate the constitutional requirement to keep government and religion separate.
The question before the Court
Did Boston violate the First Amendment's free speech guarantee by refusing to let a Christian group fly its flag on a City Hall flagpole when the city routinely allowed dozens of other private groups to fly their own flags there?
The Court's answer
Yes — the Court ruled unanimously that Boston's refusal violated the First Amendment's guarantee of free speech. The key threshold question was whether the flags flown by private groups on the City Hall flagpole amounted to "government speech" — messages the government was expressing as its own. If they had, Boston would have been free to pick and choose what flags flew there. The Court found no government speech: Boston exercised almost no editorial control over proposed flags, had no written guidelines, never reviewed flags before approvals, and had approved every single flag request until it turned down Camp Constitution's application.
Because the program functioned as an open public forum for private expression rather than a vehicle for government messaging, Boston was required to apply its rules without discriminating based on viewpoint. Religious speech is a viewpoint. Denying the Christian flag while approving secular flags was therefore unconstitutional viewpoint discrimination that the First Amendment does not permit.

Why it matters
Cities, public universities, and other government bodies that run open-access programs cannot exclude religious groups while welcoming secular ones. Wherever a government lets private parties use its resources without meaningful editorial oversight over the message, religious speakers have the same access rights as everyone else — and governments face real legal risk when they treat religion as a second-class viewpoint.
What changes now
The case goes back to the lower courts, which must enter judgment in favor of Shurtleff and Camp Constitution. Boston can no longer deny flag-raising applications simply because a flag is religious in character. Cities that want to treat a flagpole as a vehicle for government speech — and thereby retain the ability to curate its content — will need to establish genuine, written editorial control over proposed flags, not merely after-the-fact policies crafted during litigation.
What this does not decide
The ruling does not decide whether a city with a genuinely curated, formally controlled flag program could treat its flagpole as government speech and exclude religious flags on that basis. It also does not resolve whether the Establishment Clause could ever justify excluding religious symbols from government property — every justice agreed it provided no justification here.
Concurrences and dissents
Concurrence — Justice Kavanaugh
Justice Kavanaugh agreed with the majority and wrote separately to make a single, pointed observation: the entire dispute arose from Boston's mistaken belief that allowing a religious flag to fly alongside secular ones would violate the Establishment Clause. He stressed that the Establishment Clause does not require the government to exclude religious speakers from public programs — quite the opposite. Treating religious speech as ineligible for equal access itself violates the Constitution, and the government may not treat religious speakers as second-class participants in programs open to the public.
Concurrence — Justice Alito
Justice Alito agreed that Boston violated the First Amendment but rejected the majority's use of the three-factor Walker/Summum framework as a general test for identifying government speech. He argued that factors like 'control' and 'history' can mislead courts — control over private expression is also the definition of censorship, and historical associations with government do not determine whether a specific program expresses a government message. He would have focused the inquiry directly on whether the government was actually communicating its own message, concluding that Boston's flagpole program was obviously a public forum for private speech, not a vehicle for any government message.
Concurrence — Justice Gorsuch
Justice Gorsuch agreed with the result but wrote separately to argue that Boston's deeper error was its misplaced reliance on the 'Lemon test' — a three-part Establishment Clause framework from 1971 that he argued the Court has effectively abandoned. He contended that Lemon, by ignoring history and substituting a malleable 'reasonable observer' inquiry, produced decades of confused results and trapped local officials in an impossible bind, pressuring them to discriminate against religion to avoid a spurious constitutional problem. He called on lower courts and local officials to stop applying the test, arguing it was a doctrinal misadventure that this Court 'long ago interred.'
How the Court got there
The legal reasoning, step by step
- When a government opens a program to private speakers, the first legal question is whether any resulting expression qualifies as 'government speech' — meaning the government is conveying its own message, freeing it to pick and choose what gets said. Only if the flags were government speech could Boston lawfully reject the Christian flag. If the flags were private expression, the First Amendment's strict prohibition on viewpoint discrimination applied.
- To determine whether expression is government speech, the Court examined three types of evidence established in prior cases: the historical role of the means of expression, how the public would likely perceive who is speaking, and the degree to which the government actively shaped or controlled the expression.
- History favored Boston: flags flown at the seat of government have long conveyed official messages, and governments routinely use flags — including other nations' flags — to express their own statements. Public perception was also ambiguous in Boston's favor — a passerby near City Hall might assume any flag near the entrance spoke for the city. These two factors did not resolve the case, however.
- The decisive factor was control. Boston exercised almost none over the content or meaning of the privately chosen flags. The city never previewed proposed flags before approving events, had no written policy about what the flags would communicate, and had approved every single flag request for over a decade until it denied Camp Constitution's application. This thin record of editorial involvement fell far short of the active, substantive control the Court had previously found in cases involving state-designed license plates (*Walker v. Texas Division, Sons of Confederate Veterans*, where Texas 'actively' reviewed and rejected designs) and permanent monuments accepted for public parks (*Pleasant Grove City v. Summum*, where the city curated and permanently displayed donated works as its own).
- Because Boston's minimal involvement could not bring the flag raisings within the definition of government speech, the program was instead a public forum open to private expression. In any public forum, viewpoint neutrality is required — the government cannot allow speech on a topic while blocking the same topic when discussed from a religious angle. Excluding the Christian flag while welcoming secular flags was precisely that kind of viewpoint discrimination, and the First Amendment does not permit it.

Distinguishes Pleasant Grove City v. Summum (555 U.S. 460)
Boston's nearly nonexistent editorial control over flag content fell far short of the curated permanent-monument program that qualified as government speech in Summum.
Distinguishes Walker v. Texas Div., Sons of Confederate Veterans, Inc. (576 U.S. 200)
Boston's passive approval process lacked the active content review that made Texas's specialty license plate designs government speech in Walker.
