In Bates v. State Bar of Arizona, 433 U. S. 350 (1977), this Court held that truthful advertising of "routine" legal services is protected by the First and Fourteenth Amendments against *449 blanket prohibition by a State. The Court expressly reserved the question of the permissible scope of regulation of "in-person solicitation of clients—at the hospital room or the accident site, or in any other situation that breeds undue influence—by attorneys or their agents or `runners.'" Id., at 366. Today we answer part of the question so reserved, and hold that the State—or the Bar acting with state authorization— constitutionally may discipline a lawyer for soliciting clients in person, for pecuniary gain, under circumstances likely to pose dangers that the State has a right to prevent.
