Clear and present danger

Clear and present danger was a doctrine adopted by the Supreme Court of the United States to determine under what circumstances limits can be placed on First Amendment freedoms of speech, press, or assembly. The test was replaced in 1969 with Brandenburg v. Ohios "imminent lawless action" test. History Before the 20th century, most restrictions on free speech issues in the United States were imposed to prevent certain types of speech. Although certain kinds of speech continue to be prohibited in advance, dangerous speech started to be punished after the fact in the early 1900s, at a time when US courts primarily relied on a doctrine known as the bad tendency test. Rooted in English common law, the test permitted speech to be outlawed if it had a tendency to harm public welfare. Antiwar protests during World War I gave rise to several important free speech cases related to sedition and inciting violence. In the 1919 case Schenck v. United States, the Supreme Court held that an antiwar activist did not have a First Amendment right to advocate draft resistance. In his majority opinion, Justice Oliver Wendell Holmes Jr. introduced the clear and present danger test, which would become an important concept in First Amendment law
