Answer:
Texas v. Johnson
Explanation:
In Texas v. Johnson, 491 U.S. 397 (1989), the Supreme Court struck down on First Amendment grounds a Texas flag desecration law. The 5-4 decision has served as the center point of a continuing debate regarding the value of free speech as exercised through the burning of the U.S. flag as a form of political protest. The first amendment covers "no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." - https://constitution.congress.gov/
