Central Hudson Gas & Electric v. Public Service Commission (1980)
The Supreme Court struck down New York's ban on utility advertising promoting electricity use, and established a four-part intermediate scrutiny test for commercial speech. The test requires the government to show a substantial interest, that the regulation directly advances it, and that it is not more extensive than necessary.
The ruling allowed utilities to advertise again and gave courts a framework for weighing speech restrictions against state interests.
The Central Hudson test became the default standard for commercial speech cases, including advertising, professional regulation, and now algorithmic pricing.
Judge Caproni applied the Central Hudson framework to New York's rent-software ban, finding the law likely burdens protected commercial speech more than necessary.
