Bates v. State Bar of Arizona, 433 U.S. 350 (1977), was a United States Supreme Court case in which the Court upheld the right of lawyers to advertise their services.[1] In holding that lawyer advertising was commercial speech entitled to protection under the First Amendment (incorporated against the States through the Fourteenth Amendment), the Court upset the tradition against advertising by lawyers, rejecting it as an antiquated rule of etiquette.
