United States v. Eichman, 496 U.S. 310 (1990) was a United States Supreme Court case that invalidated a federal law against flag desecration as violating of free speech under the First Amendment.
 It was argued together with the case "United States v. Haggerty".
 It built on the opinion handed down in the Court's decision the prior year in "Texas v. Johnson" (1989), which invalidated on First Amendment grounds a Texas state statute banning flag-burning.
Davis v. Federal Election Commission, 554 U.S. 724 (2008), is a decision by the United States Supreme Court, which held that Sections 319(a) and (b) of the Bipartisan Campaign Reform Act of 2002 (popularly known as the McCain-Feingold Act) unconstitutionally infringed on a candidate's First Amendment rights.
Gitlow v. New York, 268 U.S. 652 (1925) , was a decision by the Supreme Court of the United States holding that the Fourteenth Amendment to the United States Constitution had extended the reach of certain limitations on federal government authority set forth in the First Amendment—specifically the provisions protecting freedom of speech and freedom of the press—to the governments of the individual states.
 It was one of a series of Supreme Court cases that defined the scope of the First Amendment's protection of free speech and established the standard to which a state or the federal government would be held when it criminalized speech or writing.
Davis v. Beason, 133 U.S. 333 (1890), was a United States Supreme Court case affirming, by a 9-0 vote, that federal laws against polygamy did not conflict with the free exercise clause of the First Amendment to the United States Constitution.
Borough of Duryea v. Guarnieri, 564 U.S. 379 (2011) , was a case in which the Supreme Court of the United States held the public concern test limits Petition Clause claims by public employees.
 More specifically state and local government employees may not sue their employers for retaliation under the Petition Clause of the First Amendment when they petition the government on matters of private concern.
 To show that an employer interfered with rights under the Free Speech Clause of the First Amendment, an employee must show that his speech related to a matter of public concern.
 The court held that this test also applies when the employee invokes the Petition Clause.
 The case is significant under the Petition Clause because 1.)
 it recognized that lawsuits are “Petitions” under the First Amendment and 2.)
 it explains that the Petition Clause and Speech Clause are not always coextensive, and leaves open the possibility that here may be additional claims under the Petition Clause which plaintiffs may invoke consistent with the purpose of that Clause.
Brandenburg v. Ohio, 395 U.S. 444 (1969) , was a landmark United States Supreme Court case based on the First Amendment to the U.S. Constitution.
 The Court held that government cannot punish inflammatory speech unless that speech is "directed to inciting or producing imminent lawless action and is likely to incite or produce such action."
 Specifically, it struck down Ohio's criminal syndicalism statute, because that statute broadly prohibited the mere advocacy of violence.
 In the process, "Whitney v. California" (1927) was explicitly overruled, and doubt was cast on "Schenck v. United States" (1919), "Abrams v. United States" (1919), "Gitlow v. New York" (1925), and "Dennis v. United States" (1951).
The Dixon School Case (Zellers v. Huff) was a lawsuit started in 1948 in New Mexico contesting the use of nuns, religious brothers and priests as teachers in publicly supported schools under the First Amendment to the United States Constitution.
 The case involved thirty schools in eleven New Mexico counties, twenty-eight plaintiffs, two hundred defendants, and public expenditures to the schools of over $600,000 annually.
 Following on the heels of the U.S. Supreme Court's decision in "Everson v. Board of Education", which applied First Amendment freedoms to state as well as federal law, the Dixon School Case was the first state case to implement separation of church and state in public schools, and was watched with interest nationally.
Osborne v. Ohio, 495 U.S. 103 (1990) , is a U.S. Supreme Court case in which the Court held that the First Amendment allows states to outlaw the mere possession, as distinct from the distribution, of child pornography.
 In so doing, the Court extended the holding of "New York v. Ferber", 458 U.S. 747 (1982) , which had upheld laws banning the distribution of child pornography against a similar First Amendment challenge, and distinguished "Stanley v. Georgia", 394 U.S. 557 (1969) , which had struck down a Georgia law forbidding the possession of pornography by adults in their own homes.
 The Court also determined that the Ohio law at issue was not overbroad, relying on a narrowing interpretation of the law the Ohio Supreme Court had adopted in prior proceedings in the case.
 However, because it was unclear whether the State had proved all the elements of the crime, the Court ordered a new trial.
Friedrichs v. California Teachers Association, 578 U.S. ___ (2016), is a United States labor law case that came before the Supreme Court of the United States.
 At issue in the case was whether "Abood v. Detroit Board of Education" should be overruled, with public-sector "agency shop" arrangements invalidated under the First Amendment, and whether it violates the First Amendment to require that public employees affirmatively object to subsidizing nonchargeable speech by public-sector unions, rather than requiring employees to consent affirmatively to subsidizing such speech.
 Specifically, the case concerned public sector collective bargaining by the California Teachers Association, an affiliate of the National Education Association.
Freedom for the Thought That We Hate: A Biography of the First Amendment is a 2007 non-fiction book by journalist Anthony Lewis about freedom of speech, freedom of the press, freedom of thought, and the First Amendment to the United States Constitution.
 The book starts by quoting the First Amendment, which prohibits the U.S. Congress from creating legislation which limits free speech or freedom of the press.
 Lewis traces the evolution of civil liberties in the U.S. through key historical events.
 He provides an overview of important free speech case law, including U.S. Supreme Court opinions in "Schenck v. United States" (1919), "Whitney v. California" (1927), "United States v. Schwimmer" (1929), "New York Times Co. v. Sullivan" (1964), and "New York Times Co. v. United States" (1971).
