576 U.S. 155 (2015)
Reed v. Town of Gilbert is a foundational modern First Amendment case that crystallizes the rule that subject-matter distinctions in speech regulations are content-based on their face and thus presumptively unconstitutional unless the government can satisfy strict scrutiny.
Is a municipal sign code that imposes different restrictions based on the subject matter or function of the sign content-based on its face such that it must satisfy strict scrutiny under the First Amendment?
A law is content-based if it applies to particular speech because of the topic discussed, the idea, or the message expressed—on its face—regardless of the government's benign motive, content-neutral justification, or lack of animus. Content-based regulations are presumptively unconstitutional and must satisfy strict scrutiny: the government must prove the regulation is narrowly tailored to serve a compelling governmental interest, and that no less restrictive, content-neutral alternative would achieve the government's objectives. Viewpoint discrimination is a subset of content discrimination, but a law can be content-based without being viewpoint-based.
Yes. Gilbert's sign code drew facial distinctions based on the signs' subject matter and purpose, making it a content-based regulation of speech. Applying strict scrutiny, the ordinance was not narrowly tailored to any compelling interest and was therefore unconstitutional.
Reed is the modern touchstone for when content discrimination triggers strict scrutiny. Its clear, facial test reshaped First Amendment doctrine and prompted waves of challenges to subject-matter-based regulations (e.g., panhandling or solicitation bans distinguishing requests for donations from other speech; differential rules for political versus other signs). Municipalities now draft sign codes to avoid content references, relying on content-neutral criteria like size, materials, location, or illumination. Subsequent decisions have clarified Reed's reach. Notably, City of Austin v. Reagan National Advertising (2022) held that on-/off-premises distinctions are location-based, not content-based, signaling that not every rule requiring reading a sign is automatically content-based. Still, Reed's core principle stands: when a law singles out speech by subject matter or message, strict scrutiny applies—and is rarely satisfied.
