Commercial Speech — Central Hudson Test and Its Erosion

For most of American constitutional history, advertising and other commercial expression received no First Amendment protection whatsoever. Courts treated commercial speech as purely economic conduct — as the Supreme Court declared in 1942, "purely commercial advertising" was outside the constitutional guarantee. That categorical exclusion ended in 1976 with Virginia State Board of Pharmacy v. Virginia Citizens Consumer Council, which held that a Virginia law prohibiting pharmacists from advertising prescription drug prices violated the First Amendment. The Court reasoned that the free flow of commercial information — to consumers, to markets, to the public — serves significant individual and social interests that the First Amendment protects. Four years later, Central Hudson Gas & Electric Corp. v. Public Service Commission (1980) established the governing four-part framework: commercial speech receives First Amendment protection if it concerns lawful activity and is not misleading, and government restrictions must (1) directly advance (2) a substantial governmental interest (3) in a reasonably proportionate way. This intermediate protection — more than nothing, less than strict scrutiny — has been applied to strike down advertising restrictions across industries. But the Central Hudson test has been under sustained pressure from two directions: Justices Thomas, Gorsuch, and others have argued commercial speech should receive the same full First Amendment protection as political speech, and NIFLA v. Becerra (2018) complicated the doctrine by refusing to recognize a lower scrutiny tier for "professional speech," raising questions about when the Central Hudson framework gives way to full strict scrutiny.

Key Mechanics

Commercial speech receives intermediate First Amendment protection under the Central Hudson four-part test (1980): (1) the speech must concern lawful activity and not be misleading; (2) the government interest must be substantial; (3) the regulation must directly advance that interest; and (4) the regulation must be no more extensive than necessary. Steps 3 and 4 are where most restrictions fail — government must show the regulation materially advances the interest, not just that it is "reasonably related." More recent cases suggest step 4 may require "narrow tailoring" akin to heightened scrutiny. Compelled commercial disclosures are judged under the more lenient Zauderer standard: if disclosures are purely factual, non-controversial, and reasonably related to preventing consumer deception, they need only be "reasonably related to the State's interest" — a much lower bar than Central Hudson.

How It Works

The Rise of Commercial Speech Protection: Virginia Board of Pharmacy

The 1976 decision in Virginia State Board of Pharmacy represents a major shift in constitutional law. Virginia prohibited pharmacists from advertising prescription drug prices — ostensibly to protect the "professional image" of pharmacists and prevent a race to the bottom on professional standards. The Court struck down the prohibition.

Justice Blackmun's majority emphasized that commercial speech serves three distinct constitutional interests: the listener's interest in receiving information, the speaker's interest in communicating, and the public's interest in the free flow of information that markets and democracy require. A consumer who cannot get price information from a pharmacist cannot make rational choices about where to buy prescriptions — and in some cases, the inability to find the cheapest prices causes real economic harm to poor consumers who rely on prescription drugs. The First Amendment is not indifferent to these harms.

The majority was careful to leave open significant government power to regulate commercial speech: false, deceptive, or misleading commercial speech can be prohibited; advertising of illegal activities is unprotected; and restrictions on commercial expression need not satisfy the same demanding standards as restrictions on political speech. The First Amendment protection for commercial speech is intermediate — more than zero, less than full.

The Central Hudson Framework

Central Hudson Gas & Electric Corp. v. Public Service Commission (1980) crystallized the doctrinal framework for evaluating commercial speech restrictions. New York's Public Service Commission had ordered utilities to cease promotional advertising during a period of energy conservation concern. Central Hudson, an electric utility, challenged the order.

The Court articulated a four-part analysis:

Step 1 — Is the speech protected? Commercial speech that concerns lawful activity and is not misleading is protected. Advertising of illegal conduct (pyramid schemes, price-fixing agreements) or deceptive advertising receives no First Amendment protection.

Step 2 — Does the government have a substantial interest? The interest the government is advancing must be substantial. Energy conservation is substantial; minor aesthetic concerns may not be. The government must identify the interest concretely, not vaguely.

Step 3 — Does the regulation directly advance the substantial interest? There must be a direct causal connection between the restriction and the interest. A ban on utility advertising to promote conservation must actually reduce energy use; if it doesn't (because advertising has minimal effect on consumption decisions), the interest is not directly advanced.

Step 4 — Is the restriction no more extensive than necessary? The restriction must be reasonably calibrated to the interest — it cannot sweep up more speech than needed. This is not the least restrictive means standard of strict scrutiny, but it does require some fit between means and end.

Central Hudson itself involved a commercial speech restriction that failed step 4: even if some promotional advertising increased energy use, a blanket prohibition on all utility advertising was more extensive than necessary to advance conservation.

Rejecting "Greater Includes the Lesser": 44 Liquormart

One argument for expansive commercial speech regulation is intuitive: if the government may ban an activity entirely, surely it may ban advertising for that activity. Posadas de Puerto Rico (1986) accepted this logic, holding that Puerto Rico could ban casino advertising directed at residents because it could prohibit gambling for residents.

44 Liquormart, Inc. v. Rhode Island (1996) explicitly repudiated Posadas on this point. Rhode Island prohibited retailers from advertising retail liquor prices anywhere except within their own stores. The state argued that because it could ban liquor sales entirely, it could certainly ban price advertising — the greater power includes the lesser.

The Court unanimously rejected this reasoning. The First Amendment protects commercial speech as a constitutional right, not merely as a government grace. The government's power to regulate an activity does not translate into power to restrict truthful speech about that activity. If governments could ban advertising for anything they could ban, the First Amendment's protection for truthful commercial information would be systematically circumvented — legislators could use advertising bans to restrict information flow without facing the constitutional scrutiny that direct prohibitions would face. The 44 Liquormart Court emphasized that direct restrictions on truthful information about lawful activities are particularly suspect because they manipulate consumers by keeping them in the dark rather than trusting them to make informed choices.

Heightened Scrutiny and Sorrell

Sorrell v. IMS Health Inc. (2011) applied heightened scrutiny to a Vermont law that prohibited pharmacies from selling prescriber-identifying information (which drugs a given doctor prescribes) to data companies and pharmaceutical marketers. Vermont argued the restriction protected prescriber privacy and prevented pharmaceutical companies from using data to influence prescribers toward brand-name drugs.

The Court struck down the law. The majority (per Justice Kennedy) emphasized that the Vermont law was both content-based (it applied only to pharmaceutical marketing, not other uses of prescriber data) and speaker-based (it prohibited data companies and pharmaceutical marketers but not others). Content- and speaker-based restrictions on speech receive heightened scrutiny — regardless of whether the speech is commercial.

Sorrell has been read as indicating a possible convergence between commercial speech doctrine and standard First Amendment analysis. If a content- or speaker-based restriction on commercial speech triggers heightened scrutiny equivalent to what political speech would receive, the Central Hudson intermediate framework may apply only to genuinely content-neutral regulations of commercial expression. Justices Thomas and Gorsuch have argued that commercial speech should receive full First Amendment protection — the lesser protection is premised on a categorical distinction that lacks principled justification.

Compelled Commercial Disclosures: Zauderer and NIFLA

A separate commercial speech doctrine governs government-mandated disclosures — requirements that commercial speakers include specific information in their advertising. These are compelled speech, but of a special kind: government often has strong interests in requiring businesses to disclose factual information (ingredients, side effects, prices, terms) to prevent consumer deception.

Zauderer v. Office of Disciplinary Counsel (1985) allowed states to require lawyers to include factual, non-deceptive disclosures in their advertising when reasonably necessary to prevent consumer deception. The Court applied a lower scrutiny standard: the required disclosure must be (1) purely factual, (2) uncontroversial, and (3) not unduly burdensome. Under this standard, required "contingency fee" disclosures, ingredient lists, nutrition facts, and similar factual disclosures survive.

NIFLA v. Becerra (2018) complicated this framework by refusing to recognize "professional speech" as a category receiving lower scrutiny. California's requirement that pregnancy centers disclose abortion services information was not merely a factual disclosure — it was ideologically charged advocacy that professionals opposed. NIFLA suggests that Zauderer's lower scrutiny applies only to genuinely factual, uncontroversial disclosures, not to government-mandated messages that professionals find objectionable.

The result is a spectrum: purely factual commercial disclosures (nutrition labels, price disclosures, licensure status) receive Zauderer's lower scrutiny; ideologically charged or controversial compelled disclosures receive higher scrutiny; outright restrictions on truthful commercial advertising receive Central Hudson or Sorrell heightened scrutiny.

How It Affects You

If you are an advertiser, marketer, or business subject to advertising restrictions: The Central Hudson framework gives you significant but not unlimited protection for truthful advertising of lawful products and services. Government restrictions on your truthful advertising must be directly related to a substantial interest and reasonably calibrated to that interest. If a regulator bans truthful price advertising, prohibits you from listing your services' benefits, or restricts comparative advertising, assess the restriction under Central Hudson: Does the government have a substantial interest? Does the advertising restriction directly advance that interest? Is it narrowly drawn? Many restrictions fail step 3 or 4. The 44 Liquormart rule means that even regulated industries — alcohol, firearms, tobacco, pharmaceuticals — have First Amendment rights to truthful advertising about legal products. Content- or speaker-specific advertising restrictions receive heightened scrutiny under Sorrell.

If you are a regulated professional (doctor, pharmacist, lawyer, financial advisor): You have First Amendment rights in your commercial speech — advertising your services, communicating with clients about lawful options, and resisting government-mandated communications that you find objectionable. Government disclosure requirements in your professional advertising must satisfy Zauderer: they must require only purely factual, uncontroversial disclosures. Compelled endorsements of competing services, required confessions of ideological positions, or mandated communications that misrepresent your actual services are more likely unconstitutional after NIFLA. Consult First Amendment counsel before complying with disclosure mandates that require you to communicate government-chosen messages you find objectionable.

If you are a federal or state regulator restricting commercial speech: Central Hudson provides meaningful but not unlimited authority. You must identify a substantial governmental interest with specificity, demonstrate that your restriction directly advances that interest (with evidence, not speculation — the restriction must actually reduce the harm), and show that the restriction is not more extensive than necessary. Restrictions that can be replaced with disclosure requirements (letting consumers choose rather than restricting their information) typically fail the no more extensive than necessary prong. If your restriction is content- or speaker-based — targeting specific advertisers or specific messages rather than the manner or time of commercial speech — you face heightened scrutiny under Sorrell. Design regulations to be as content-neutral as possible.

If you are a consumer advocate or public health organization: Commercial speech doctrine constrains tobacco advertising restrictions, pharmaceutical marketing limits, alcohol advertising rules, and other restrictions designed to protect consumers from harmful products. Under Central Hudson, these restrictions can survive if they directly advance substantial interests in a non-excessive way. The prohibition on cigarette advertising on television (47 U.S.C. § 317, FCC rules) and the requirement of health warnings have survived challenge. But expansive restrictions — banning all alcohol price advertising, prohibiting pharmaceutical manufacturers from discussing off-label uses with physicians — have been struck down or constrained. Design public health advertising regulations narrowly around documented empirical links between the advertising and the harm.

State Variations

Commercial speech protection under the First Amendment is a federal constitutional floor that applies to all government actors. States interact with the doctrine primarily through:

State consumer protection law: Most state consumer protection laws regulate deceptive, misleading, or unfair commercial speech with specificity. These regulations are generally constitutional because deceptive commercial speech is unprotected under the first prong of Central Hudson. FTC Act § 5 and state analogues prohibit unfair or deceptive trade practices; these generally do not present First Amendment problems because the unprotected category includes deceptive speech.

State professional speech regulations: States regulate the commercial speech of licensed professionals — attorneys' advertising (governed by state bar rules), physicians' communications with patients, financial advisors' client communications. Post-NIFLA, state professional disclosure requirements face heightened First Amendment scrutiny if they require professionals to communicate government-chosen messages rather than purely factual disclosures.

State tobacco, alcohol, and cannabis advertising: State restrictions on advertising regulated commodities (tobacco, alcohol, cannabis, firearms) face Central Hudson scrutiny. State cannabis advertising regulations are particularly active — states that have legalized cannabis face the anomaly of a state-lawful product that is federally illegal, creating unclear commercial speech protections. Some state cannabis advertising restrictions have been challenged on Central Hudson grounds.

California and stricter disclosure requirements: California has historically imposed stricter commercial disclosure requirements than federal law — requiring warning labels for carcinogens under Proposition 65, disclosure of chemicals in consumer products, and nutritional information beyond federal mandates. Post-NIFLA, some California disclosure requirements may face heightened First Amendment scrutiny if they are not purely factual or impose substantial burdens.

Pending Legislation

• Pharmaceutical marketing restrictions: Federal legislation periodically proposed to restrict direct-to-consumer pharmaceutical advertising, particularly for opioids and other high-risk drugs; such restrictions face Central Hudson scrutiny and must demonstrate direct advancement of public health interests.
• Social media advertising disclosure: Federal legislation requiring disclosure of paid political advertising and sponsored content on social media raises commercial speech questions about mandated disclosures; must satisfy Zauderer for purely factual disclosures or Central Hudson for restrictions.
• Cannabis advertising regulation: As more states legalize cannabis, pressure on Congress to develop federal cannabis advertising standards has grown; the interplay between federal prohibition and state commercialization creates unusual First Amendment complications.

Recent Developments

• 2018 — NIFLA v. Becerra: Rejected "professional speech" lower scrutiny category; compelled professional speech disclosures must be purely factual to receive Zauderer's deferential treatment. Reshaped state disclosure requirements for licensed professionals.
• 2020 — AMG Capital Management v. FTC: FTC Act § 13(b) does not authorize the FTC to seek equitable monetary relief (disgorgement) in federal court — limiting FTC enforcement against deceptive advertising; Congress has considered legislation to restore FTC monetary remedy authority.
• 2023 — National Pork Producers Council v. Ross: California's Proposition 12 requiring that pork products sold in California come from pigs with certain living conditions upheld against dormant Commerce Clause challenge; case is commercial regulation not speech, but illustrates the reach of state commercial regulation.
• 2024–2026 — AI and algorithmic speech: Whether algorithmic curation, AI-generated advertising, and synthetic content receive commercial speech protection or some other First Amendment treatment is an emerging and unresolved question; courts have not yet settled whether Central Hudson or full strict scrutiny applies to AI-generated commercial content.
