In Central Hudson Gas & Electric Corp. v. Public Service Commission of New York, 447 U.S. 557 (1980), the Court determined the validity of government restrictions on commercial speech by applying a four-part test that asks: (1) whether the regulated commercial speech concerns lawful activity in a manner that is not misleading; (2) whether the restriction seeks to implement a substantial governmental interest; (3) whether it directly advances that interest; (4) whether it reaches no further than necessary to accomplish the given objective.
