Appellee challenged a Georgia statute providing that "[a]ny person who shall, without provocation, use to or of another, and in his presence . . . opprobrious words or abusive language, tending to cause a breach of the peace . . . shall be guilty of a misdemeanor," and had not been narrowed by the Georgia courts to apply only to "fighting" words "which by their very utterance . . . tend to incite an immediate breach of the peace," was on its face unconstitutionally vague and overbroad under the First and Fourteenth Amendments.
