Defamation Unified Rule
IF a plaintiff seeks damages for defamatory false statements on matters of public concern, THEN public officials and public figures must prove (1) actual malice by clear and (2) convincing evidence, while private individuals must show (1) at least negligence for actual damages and (2) actual malice for presumed or punitive damages; parody or satire about public figures is protected unless it asserts or implies actual facts. (Sullivan; Butts; Walker; Gertz; Hustler).
Commercial Speech Unified Rule
IF the government restricts truthful, non-misleading commercial advertising about lawful goods or services, THEN the regulation must (1) serve a substantial interest, (2) directly and materially advance that interest with evidence, and (3) achieve it through a reasonably tailored, not overly extensive, means after considering less-restrictive alternatives; blanket bans and paternalistic justifications are presumptively invalid. Non-truthful commercial advertising has no protection. (Virginia Pharmacy; Central Hudson; 44 Liquormart; Lorillard; Thompson).
Obscenity Unified Rule
IF the state regulates material as obscenity, THEN the work is unprotected only if it satisfies the full Miller test— (1) prurient appeal under local community standards, (2) patently offensive depictions defined by law, (3) and no serious literary, artistic, political, or scientific value—recognizing that private possession is protected but distribution and public exhibition may be prohibited. (Roth; Alberts; Miller; Stanley; Reidel; Paris Adult Theatre).
Child Pornography Unified Rule
IF expression depicts real children in sexual conduct or proposes transactions involving such material, THEN it is categorically unprotected regardless of obscenity, while virtual or computer-generated depictions with no real minors involved remain protected unless independently obscene. (Ferber; Ashcroft v. Free Speech Coalition; Williams).
Lewd /indecent Expression Unified Rule
IF the government restricts vulgar, indecent, offensive, or non-obscene (but potentially sensitive) expression, THEN the regulation is invalid unless (1) it is justified by considerations other than mere offensiveness—such as genuine secondary effects or protecting minors through reasonably tailored measures—and (2) it does not substantially reduce adults’ access to protected speech; the state may not “cleanse” public discourse, suppress lawful adult material, ban protected categories on moral or speculative grounds, or force or restrict platforms’ editorial choices. (Young; Reno; Free Speech Coalition v. Paxton; Ashcroft v. ACLU)
Hate Speech + True Threats Unified Rule
IF the government seeks to regulate hate speech, THEN it must (1) avoid both viewpoint discrimination and selective subject-matter bans even within unprotected categories, (2) may punish true threats or enhance criminal penalties only upon proof of intent to intimidate (R.A.V.; Virginia v. Black; Wisconsin v. Mitchell)
New York Times v. Sullivan (1964)
Event: A civil-rights advertisement criticizing Montgomery police contained minor factual inaccuracies that Commissioner Sullivan said defamed him. Challenge: Alabama law allowed liability without proof of fault, which the Times argued chilled criticism of public officials on public matters. Holding/Outcome: The Court reversed because Sullivan, as a public official, failed to prove actual malice—knowledge of falsity or reckless disregard—by clear and convincing evidence, since the record showed only minor errors without serious doubt about truth.
Curtis Publishing v. Butts / AP v. Walker (1967)
Event: National publications accused Butts of fixing a football game and Walker of leading a violent mob during desegregation unrest. Challenge: Both plaintiffs claimed they did not need to satisfy the Sullivan standard because they were not government officials. Holding/Outcome: The Court required public figures to prove actual malice and applied it by finding reckless disregard in Butts due to sloppy sourcing but not in Walker because the reporter’s on-scene observations negated serious doubts about truth.
Gertz v. Robert Welch (1974)
Event: A magazine falsely labeled attorney Elmer Gertz a Communist conspirator involved in framing police. Challenge: The publisher claimed Sullivan’s actual-malice rule applied to all speech on public issues, even against private figures. Holding/Outcome: The Court reversed and remanded because Gertz, as a private figure, needed only to show negligence for actual damages, while presumed/punitive damages required actual malice that the defendant could not establish.
Central Hudson v. PSC (1980)
Event: New York banned all promotional advertising by electric utilities to conserve energy. Challenge: Central Hudson argued the ban suppressed truthful speech far beyond what was necessary. Holding/Outcome: The Court invalidated the ban because although conservation was substantial, the state offered no evidence of direct advancement and adopted an overbroad prohibition failing the reasonable-fit requirement.
44 Liquormart v. Rhode Island (1996)
Event:
Rhode Island enacted a comprehensive ban on advertising retail liquor prices, preventing sellers from disseminating truthful, non-misleading price information in any medium.
Challenge:
Retailers argued the ban violated the First Amendment because it suppressed accurate commercial information solely to influence consumer behavior, and the State lacked evidence that obscuring prices actually promoted temperance under the Central Hudson test.
Holding/Outcome:
The Court invalidated the ban. Applying Central Hudson, it held
Step 1 — Lawful & Truthful?
Liquor price advertising concerns a lawful product and is truthful / nonmisleading → Passes Step 1.
Step 2 — Substantial Government Interest?
Rhode Island asserts temperance (reducing alcohol consumption) → Assume substantial → Passes Step 2.
Step 3 — Direct Advancement?
Rhode Island presented no evidence that banning price ads reduces consumption; the District Court found zero measurable effect → Fails Step 3 (no material advancement).
Step 4 — Not More Extensive Than Necessary?
State had obvious non-speech alternatives (raise taxes, regulate minimum prices, ration sales, public education). A total ban on truthful information is far broader than necessary → Fails Step 4.
Roth v. United States (1957)
Event: Roth ran a mail-order business selling sexually explicit publications and was convicted under a federal ban on mailing obscene materials.
Challenge: He argued the statute violated the First Amendment by criminalizing the distribution of sexual expression.
Holding/Outcome: The Court upheld his conviction, holding that obscenity is categorically unprotected speech and defining it as material that, taken as a whole, appeals to the prurient interest and is utterly without redeeming social importance
Miller v. California (1973)
Event (1 sentence):
Miller mailed unsolicited brochures containing explicit sexual images, triggering prosecution under a California law prohibiting the distribution of obscene materials.
Challenge (1 sentence):
He argued the statute was unconstitutionally vague and overbroad because earlier standards gave inadequate notice of what sexual expression could be criminalized.
Holding / Application (1 sentence):
The Court created the three-part Miller test for obscenity and vacated Miller’s conviction because the jury had been instructed under outdated standards, requiring the state on remand to apply the new prurience, patent offensiveness, and serious-value prongs before imposing liability
Stanley v. Georgia (1969)
Event: Police found obscene films in Stanley’s home during a search unrelated to obscenity. Challenge: Stanley argued the state could not criminalize mere private possession. Holding/Outcome: The Court reversed because even though obscenity is unprotected, private possession in the home is constitutionally protected by the First Amendment and the privacy right.
New York v. Ferber (1982)
Event: Ferber sold films showing real minors engaged in sexual conduct. Challenge: He argued the material was non-obscene and thus protected under Miller. Holding/Outcome: The Court affirmed because the films satisfied all Ferber elements—real children, sexual conduct, inherent exploitation harm, and a compelling state interest—making them categorically unprotected regardless of obscenity.
Ashcroft v. Free Speech Coalition (2002)
Event: Congress criminalized “virtual” child pornography that did not use real children. Challenge: Plaintiffs argued the law outlawed protected speech with no actual victims. Holding/Outcome: The Court struck down the law because virtual images failed the Ferber criteria—no real children and no exploitation—and thus could be restricted only if obscene under Miller, which many were not.
United States v. Williams (2008)
Event: Williams, in an undercover sting, offered an agent “good” child-pornography images and was charged under 18 U.S.C. § 2252A(a)(3)(B), which bars knowingly advertising or soliciting material in a way that signals it depicts real minors in sexually explicit conduct.
Challenge: He claimed the statute was facially overbroad under Free Speech Coalition because it punished speech about non-existent images and mere “pandering,” sweeping in protected offers or boasts unrelated to actual child pornography.
Holding/Outcome: The Court upheld the law and his conviction because § 2252A(a)(3)(B) regulates unprotected offers and solicitations to transact in illegal child pornography, requiring the defendant to knowingly propose a deal he believes—or intends others to believe—involves real-minor depictions, even if no actual images or minors exist.
Free Speech Coalition v. Paxton (2025)
Event: Texas enacted H.B. 1181 requiring age verification for access to commercial websites containing sexual material harmful to minors. Challenge: Plaintiffs argued the law burdened adult access to protected speech and imposed unconstitutional identification requirements. Holding/Outcome: The Court upheld the law under intermediate scrutiny because it targeted only material harmful to minors, allowed adults continued access after minimal verification, and was reasonably tailored in light of less-restrictive but insufficient alternatives.
Reno v. ACLU (1997)
Event: Congress criminalized transmitting “indecent” or “patently offensive” internet content accessible to minors. Challenge: Plaintiffs argued the law suppressed vast amounts of lawful adult speech. Holding/Outcome: The Court invalidated the CDA because it fail its vague, sweeping categories burdened protected adult speech and less-restrictive alternatives like filters existed.n
Young v. American Mini Theatres (1976)
Event: Detroit zoned adult theaters away from each other and residential areas. Challenge: Owners argued the ordinance discriminated based on content. Holding/Outcome: The Court upheld the ordinance because it satisfied the secondary-effects test by targeting crime and blight and preserving reasonable alternative avenues for adult expression.
R.A.V. v. City of St. Paul (1992)
Event: A juvenile burned a cross on an African-American family’s lawn and was charged under a St. Paul ordinance that criminalized symbols—like burning crosses or swastikas—that one knows will arouse anger or alarm on the basis of race, color, creed, religion, or gender.
Challenge: He argued the ordinance was unconstitutional because it selectively prohibited only race-, religion-, or gender-based fighting words while leaving all other fighting words outside the statute’s scope.
Holding/Outcome: The Court reversed because the ordinance impermissibly discriminated by viewpoint within an unprotected category, punishing only bias-based fighting words while permitting other fighting words, thus violating
the First Amendment’s requirement of content and viewpoint neutrality.
Virginia v. Black (2003)
Virginia charged defendants under a statute that made it a felony to burn a cross “with intent to intimidate,” and that further declared any cross-burning to be prima facie evidence of that intent.
Challenge:
Defendants argued the law was unconstitutional because the prima facie provision allowed the state to infer intimidating intent automatically from the act itself—sweeping in expressive or ideological cross-burnings and effectively eliminating the constitutionally required showing that the defendant intended to make a true threat.
Holding/Outcome:
The Court held that a state may prohibit cross-burning undertaken with a proven intent to intimidate, since such conduct qualifies as a true threat. But it struck down Virginia’s prima facie clause as unconstitutional because it presupposed the intent element and removed the state’s burden to prove intimidation. As applied, the Court vacated the conviction of one defendant and remanded the others’ cases, explaining that while a properly narrowed intimidation-based prohibition could be valid, the statute could not be enforced through an automatic presumption of intent.
Wisconsin v. Mitchell (1993)
Event:
Mitchell participated in a group assault on a white teenager, and his sentence was enhanced under Wisconsin’s hate-crime statute because he selected the victim on the basis of race.
Challenge:
Mitchell argued the enhancement violated the First Amendment by effectively punishing him for his thoughts, beliefs, or prior statements reflecting racial bias.
Holding/Outcome:
The Court unanimously upheld the enhancement. It explained that the First Amendment does not prevent the state from imposing a harsher penalty for an assault aggravated by a bias motive, because the statute punishes conduct—a violent crime—whose motive makes it more harmful, not the defendant’s abstract beliefs or protected expression.
