Branzburg v. Hayes is a landmark decision in which the U.S. Supreme Court rejects First Amendment protection for reporters called before a grand jury to reveal confidential information or sources. Reporters argued that if they were forced to identify their sources, their informants would be reluctant to provide information in the future. The Court decides reporters are obliged to cooperate with grand juries just as average citizens are. The justices do allow a small exception for grand jury investigations that are not conducted or initiated in good faith.
