Central Hudson v. Public Service Commission (1980): The Case That Set the Standard for Commercial Speech
Are advertisements merely commercial activity, or are they protected by the Constitution as free speech?
Hello! Today I’m introducing a landmark case that defined the scope of protection for commercial speech: Central Hudson Gas & Electric Corp. v. Public Service Commission (1980). Studying this case made me wonder: “Can corporate advertising be seen as part of free speech?” At the time, New York’s Public Service Commission banned electric utilities from advertising in order to conserve energy. The Supreme Court had to determine whether that ban exceeded constitutional limits. The ruling produced the enduring ‘Central Hudson test’.

Background
Amid the energy crisis of the 1970s, New York’s Public Service Commission (PSC) prohibited electric utilities from running ads that encouraged electricity consumption, citing energy conservation and the public interest. Central Hudson Gas & Electric challenged the rule, arguing that it violated the First Amendment’s free speech protections. The case ultimately required the Supreme Court to decide how far commercial speech may be protected under the Constitution.
Issues & Legal Questions
The central questions were whether commercial advertising is protected speech and, if so, what standards allow the government to restrict it.
| Side | Argument | Key Point |
|---|---|---|
| Public Service Commission (PSC) | The ad ban is a justified regulation to promote the public interest and conserve energy. | Government’s regulatory authority |
| Central Hudson | Commercial advertising should also be protected as part of free speech. | Constitutional status of commercial speech |
Decision & Reasoning
The Supreme Court ruled 8–1 that the PSC’s blanket ban on advertising was unconstitutional. However, it emphasized that commercial speech is not protected without limits and requires a specific standard of review. From this, the famous ‘Central Hudson test’ emerged.
- Is the speech about lawful activity and not misleading?
- Is the government’s interest substantial?
- Does the regulation directly advance that interest?
- Is the regulation no more extensive than necessary (a reasonable fit)?
These four steps have since become the core standard for reviewing commercial-speech restrictions in the United States.
Impact
Central Hudson recognized constitutional protection for commercial speech while also placing principled limits on government regulation. The decision clarified that corporate advertising, marketing, and financial product information fall under the First Amendment. At the same time, any regulation must satisfy a substantial public interest and the no-more-extensive-than-necessary principle.
Related Cases
The Central Hudson test has been repeatedly applied in later cases. Here’s a comparison of representative decisions:
| Case | Key Issue | Holding |
|---|---|---|
| Central Hudson v. PSC (1980) | Limits on regulating commercial ads | Unconstitutional — test established |
| Posadas v. Tourism Co. of Puerto Rico (1986) | Restrictions on casino advertising | Upheld — deference to government |
| 44 Liquormart v. Rhode Island (1996) | Ban on advertising liquor prices | Unconstitutional — Central Hudson reinforced |
Modern Significance
The Central Hudson test remains a living standard today. It is frequently applied to new forms of commercial expression—e-cigarette marketing, online ads, and financial product promotions. Still, some scholars and judges criticize the test as vague and too restrictive of government regulation.
- Commercial speech is protected by the Constitution.
- Government restrictions are allowed only for substantial interests and within minimal, necessary bounds.
- A standard applied to emerging issues in the digital age.
- Continues to spark robust legal and academic debate.
FAQ
Whether commercial advertising is protected speech—and the standards for when government may restrict it.
By a vote of 8–1, it struck down New York’s advertising ban as unconstitutional and established the “Central Hudson test” for commercial-speech review.
A four-step standard asking about lawfulness and non-misleading speech, substantial government interest, direct advancement, and whether the restriction is no more extensive than necessary.
Yes. It continues to govern newer disputes about e-cigarette ads, online marketing, and financial product promotions.
It clarified that corporate advertising and marketing receive constitutional protection, expanding businesses’ freedom to communicate.
Some argue the test is vague, makes legitimate regulation too difficult, and overprotects corporate speech at the expense of the public interest.
Conclusion
Today we looked at Central Hudson v. Public Service Commission (1980), a case that squarely addressed the freedom of commercial speech. Studying it deepened my thinking about whether advertising should be protected as free speech—not only because of corporate interests, but also because it affects consumers’ access to information and free communication in a democracy. At the same time, there are clearly situations where advertising can cause social harm and regulation is warranted. Ultimately, this case shows how to balance liberty and regulation.
