Central Hudson Gas & Electric Corp. v. Public Service Commission is the Supreme Court case that created the four-part test for regulating commercial speech under the First Amendment. In Constitutional Law I, it is the main case for how courts judge limits on business advertising.
Central Hudson Gas & Electric Corp. v. Public Service Commission is the Supreme Court case that tells Constitutional Law I students how to analyze government limits on commercial speech, which means advertising and other speech proposing a commercial transaction. The case comes up when the government tries to regulate business messages because it thinks the speech is misleading, harmful, or tied to a public problem.
The dispute started during an energy crisis in the late 1970s. New York’s Public Service Commission barred electric utilities from advertising in order to reduce demand for electricity. Central Hudson, a utility company, challenged the ban, arguing that the state could not just silence truthful advertising because officials wanted people to use less power.
The Court agreed that commercial speech gets First Amendment protection, even though it is not protected as strongly as political speech. That middle position matters a lot in Con Law I. The Court did not say businesses have absolute freedom to advertise, but it also rejected the idea that the government can regulate commercial speech as if it were ordinary conduct.
To decide when regulation is allowed, the Court announced a four-part test. First, ask whether the speech concerns lawful activity and is not misleading. If the answer is no, the government has more room to regulate. If the answer is yes, the court moves to the next steps: does the government claim a substantial interest, does the regulation directly advance that interest, and is the regulation no more extensive than necessary?
That last step does not mean the state must choose the absolute least restrictive option in every case, but the fit between the law and the government’s goal has to make sense. In practice, the Court uses Central Hudson to check whether a speech restriction is a real response to a problem or just a broad ban that sweeps too far.
A good way to remember the case is to see it as a balancing tool. The government can regulate false or harmful commercial messages more easily, but truthful advertising for lawful products still gets constitutional protection. That balance is why Central Hudson appears again and again in First Amendment cases about ads, professional speech, and consumer protection rules.
Central Hudson matters because it gives you the standard court structure for analyzing commercial speech cases in Constitutional Law I. Once you know the four-part test, you can read a fact pattern and ask the same sequence of questions instead of guessing whether the government wins or loses.
It also shows how the First Amendment works differently for different kinds of speech. Political speech usually gets the strongest protection, but advertising gets a more limited one. That distinction comes up when a professor wants you to compare speech categories, explain why a law survives review, or trace how the Court balances expression against public regulation.
The case is also a bridge between doctrine and policy. The energy crisis facts make it easy to see why the state wanted to act, but the Court still worried about overbreadth. That tension shows up in later debates about consumer warnings, professional advertising, and regulations aimed at steering market behavior.
In class discussions and essays, Central Hudson gives you language to talk about fit. Instead of saying a law is just "too much," you can explain whether it directly advances a substantial government interest and whether it reaches farther than necessary. That is exactly the kind of legal reasoning Con Law I asks you to practice.

Central Hudson is the leading case for commercial speech, which is speech that proposes a transaction or advertises a product or service. The case explains why this kind of speech gets First Amendment protection, but not the same level of protection as political speech. If a fact pattern involves ads, pricing rules, or business marketing, this is usually the doctrine you reach for first.
First Amendment
The case lives inside First Amendment doctrine, but it shows that speech protection is not all-or-nothing. Con Law I uses Central Hudson to show how the Court sorts different kinds of expression and gives each a different level of protection. That makes it useful when you compare speech cases involving government regulation, censorship, or consumer protection.
Four-Part Test
The four-part test is the tool the Court created in Central Hudson. You use it step by step to check whether commercial speech can be restricted. In exam-style analysis, this test gives you a clean structure: lawful and non-misleading speech, substantial interest, direct advancement, and a regulation that is not more extensive than necessary.
Compelling Interest Test
Students sometimes confuse Central Hudson with strict scrutiny or the compelling interest test, but they are not the same. Central Hudson is a lower level of review for commercial speech, so the government does not have to meet the same demanding standard used in many other constitutional rights cases. That difference matters when you are comparing how hard it is to uphold a law.
A case-ID or essay prompt will usually ask you to apply Central Hudson to a government restriction on advertising, pricing, or other business speech. Your job is to walk through the four parts in order and decide whether the speech is truthful, whether the state has a substantial interest, and whether the rule fits that goal closely enough. If the problem involves a ban on an entire category of ads, that is a red flag for the third and fourth parts of the test.
In a short answer, name the case, state that it protects commercial speech, and then apply the test to the facts. In a longer essay, explain why the government wants the regulation, then show where the law is too broad or too narrow. Professors often want to see you distinguish commercial speech from political speech and explain why the First Amendment analysis is less protective here.
Central Hudson is often mixed up with strict scrutiny because both ask about government interests and fit. The difference is that Central Hudson is the commercial speech test, while the compelling interest test is a stricter standard used in other constitutional settings. If the speech is commercial, start with Central Hudson instead of jumping straight to strict scrutiny.
Central Hudson Gas & Electric Corp. v. Public Service Commission is the Supreme Court case that created the main test for regulating commercial speech under the First Amendment.
The case says truthful, lawful commercial speech gets constitutional protection, even though it gets less protection than political speech.
The four-part test asks whether the speech is lawful and non-misleading, whether the government has a substantial interest, whether the regulation directly advances that interest, and whether the rule is no more extensive than necessary.
The case is especially useful when a law targets advertising, consumer messages, or business promotion instead of punishing conduct directly.
In Constitutional Law I, Central Hudson is a go-to tool for analyzing how courts balance free speech rights against government regulation of the market.
It is the Supreme Court case that established the four-part test for reviewing government regulations of commercial speech. In Con Law I, it is the standard case for ads, business messaging, and other speech tied to commerce. The Court held that truthful commercial speech is protected, but not as strongly as political speech.
First, ask whether the speech concerns lawful activity and is not misleading. Then ask whether the government has a substantial interest, whether the regulation directly advances that interest, and whether the restriction is no more extensive than necessary. That sequence is the core of the case.
Central Hudson is a lower, more flexible test for commercial speech. Strict scrutiny usually applies when the government burdens highly protected rights, and it asks for a compelling interest and narrow tailoring. Central Hudson still checks the government’s reasons and the fit of the law, but it is not the same demanding standard.
The Court thought New York’s ban went too far by silencing an entire category of truthful advertising during the energy crisis. The state had an interest in conserving electricity, but the restriction was broader than needed to advance that goal. The case shows how a court can reject an overbroad speech regulation even when the government’s goal is legitimate.
