A First Amendment framework that classifies government property by the degree of speech protection afforded, treating traditional public forums such as streets and parks as sites where content-based restrictions trigger strict scrutiny.
Paul Peterson stands on a public sidewalk within the restricted zone holding a sign condemning a foreign government's policies. Officers arrest him under a local ordinance that prohibits only such critical messages. The court invalidates the ordinance because the restriction singles out political content in a traditional public forum and fails strict scrutiny.
Pearl Porter erects a cross on the capitol square during the holiday season after the state board denies her permit. The board had allowed other private holiday displays.

Pavel Petrov applies to register a trademark containing a disparaging term for his band. The patent office rejects the application on dignity grounds. The court holds that the denial constitutes viewpoint discrimination against private speech and cannot be justified under the public forum or government-speech doctrines.
Strict scrutiny applies. The government must show that the restriction is narrowly tailored to serve a compelling interest. Primary authorities illustrate that selective bans on political signs or picketing fail this test when they target particular messages.
Traditional public forums are streets and parks that have historically been open for speech. Designated public forums arise when the government intentionally opens property for expressive activity by certain groups. Both receive heightened protection against content discrimination.
Yes, provided the restrictions are content neutral, narrowly tailored to a significant government interest, and leave open ample alternative channels. A ban on focused residential picketing satisfies these criteria when it protects home privacy without regard to message.
The university creates a designated public forum and may not exclude groups based on the religious content of their speech. Such exclusion constitutes impermissible content discrimination under the First Amendment.
