Whether promotional advertising by a regulated electric-utility monopoly is commercial speech protected by the First Amendment.
Holding
Yes. Truthful promotional advertising about lawful electric services is protected commercial speech even when the speaker is a regulated monopoly.
Reasoning
Commercial speech serves not only the economic interests of the speaker but also consumers’ and society’s interest in receiving useful market information. The First Amendment rejects the paternalistic premise that government may keep consumers uninformed simply because it doubts the wisdom of the choices they may make with more information.
The utility’s monopoly status did not eliminate the value of its advertising. Electricity competes with substitute fuels, such as oil and natural gas, in markets for home heating and industrial power. Consumers therefore may benefit from information about the relative advantages of electricity and competing energy sources.
Even in a monopoly market, consumers may need information about new services, terms, or ways to use a service. The Court declined to presume that a business would pay for wholly useless advertising, and it found no unusual circumstance here that would remove Central Hudson’s messages from First Amendment protection.
