Critical Signs Near Embassy
Philip Powell stands on a public sidewalk 300 feet from a foreign embassy holding a sign that criticizes the embassy's home government. City police cite him under an ordinance that prohibits only signs critical of foreign governments within 500 feet of embassies. The ordinance is enforced against Powell while signs praising the same government remain undisturbed.
Viewpoint Ban on Cross Burning
Paula Pierce burns a cross on a public street corner to express racial hatred. City police arrest her under an ordinance that bans only cross burning and similar symbols when they convey messages of racial or religious animus. The same ordinance leaves untouched other fighting words or symbols expressing different viewpoints on the same public street.

University Funding for Religious Paper
Pamela Phillips, a student editor, submits a religious newspaper for reimbursement from a public university's student activity fund.

The university had opened the fund to a wide range of student groups for expressive purposes.

Common questions
Frequently Asked
4
What kinds of restrictions may the government impose in a public forum?+
The government may impose content-neutral time, place, or manner restrictions that are narrowly tailored to serve a significant governmental interest and leave open ample alternative channels of communication. Content-based restrictions trigger strict scrutiny and are rarely upheld.
How does a designated public forum differ from a traditional public forum?+
A traditional public forum is property that has historically been open to public expression, such as streets and parks. A designated public forum arises when the government intentionally opens property for expressive use by the public or a class of speakers, even if it was not traditionally used that way.
Does viewpoint discrimination remain invalid even in a limited public forum?+
Yes. Even when the government creates a limited public forum for a particular class of speakers or topics, it may not discriminate against speakers based on their viewpoint within the forum's scope.
Are public streets always treated as public forums?+
Public streets are the paradigm of traditional public forums when they remain open to general traffic and expression. Streets that the government has closed or reserved exclusively for non-expressive uses may lose that status.
