Chilling effect is a concept referring to deterrence in the exercise of the speech and association rights protected by the First Amendment as a result of government laws or actions that appear to target expression. It is closely related to the overbreadth doctrine, which prohibits the government from casting too wide a net when regulating activities related to speech and expression.
The Supreme Court developed and explained the chilling effect doctrine in several opinions issued during the McCarthy era involving legislation and regulations aimed at suspected communists and so-called subversives. In Baggett v. Bullitt (1964), the Court struck down loyalty oaths requiring Washington state employees to affirm that they were not members of alleged subversive organizations and requiring teachers to swear to promote “undivided allegiance to the government of the United States.” In ruling that these provisions violated the First Amendment rights of employees, who would be unable to determine what they were swearing to, the Court asserted that “the threat of sanctions may deter . . . almost as potently as the actual application of sanctions.”
In Lamont v. Postmaster General (1965), the Court struck down a postal regulation requiring individuals who wished to receive communist literature to sign up at the post office. Although the program included no sanctions against recipients, the Court said it would chill individuals who wanted the material but were afraid to make their wishes known to the government. The chilling effect of such governmental requirements was exacerbated by widespread knowledge that under the guidance of Director J. Edgar Hoover the FBI had gathered dossiers recording the political beliefs and associations of millions of Americans suspected of “un-American” views and activities.
The chilling effect doctrine reached its zenith in Dombrowski v. Pfister (1965), a case involving the Louisiana Subversive Activities and Communist Control Law and Communist Propaganda Control Law, which the state was using to require civil rights groups to register as communist-front organizations. In a groundbreaking opinion written by Justice William J. Brennan Jr., the Court ruled that not only was the Louisiana law unconstitutional, but that the federal courts could enjoin the state of Louisiana from bringing prosecutions under it. The Court rejected the notion that injunctions were unavailable in situations involving criminal prosecution because defendants always had the right of appeal if convicted under unconstitutional statutes. Although an appeal might provide adequate protection for the rights of the criminal defendants, Brennan wrote that such an appeal would not protect the First Amendment rights of third parties who might be deterred from speaking out in the interim.
Chilling effect as an independent reason for challenging government action suffered a devastating setback in Laird v. Tatum (1972), in which a new Supreme Court majority dismissed a case brought by civil rights and anti-war activists seeking an injunction against the army’s Domestic Intelligence Program, which had compiled dossiers on political protesters, including the plaintiffs. The Court ruled 5-4 that the plaintiffs could not base a challenge to government policy on the chilling effect it would have on third parties and that the plaintiffs themselves were obviously not chilled since they had been willing to identify themselves publicly by filing suit.Send Feedback on this article
