Some limits on expression were contemplated by the framers and have been read into the Constitution by the Supreme Court. In 1942, Justice Frank Murphysummarized the case law: "There are certain well-defined and limited classes of speech, the prevention and punishment of which have never been thought to raise a Constitutional problem. These include the lewd and obscene, the profane, the libelous and the insulting or 'fighting' words – those which by their very utterances inflict injury or tend to incite an immediate breach of the peace."[79]
