Board of Trustees of State University of New York v. Fox, 492 U.S. 469 (1989), is a United States Supreme Court case in which the Court instructed a lower court to reevaluate the compatibility of a resolution of the State University of New York that prohibited private commercial enterprises from operating in SUNY facilities with the First Amendment. The Court instructed the lower court to use the standard outlined in Central Hudson Gas & Electric Corp. v. Public Service Commission (1980) and determine whether the restriction on speech advanced the state's interest and, if so, whether the state's method was the least restrictive means to that end. This approach ensures a balanced consideration, safeguarding the fundamental right to free speech while addressing the state's concerns in the most efficient and non-restrictive manner possible.
