Healy v. James
408 U.S. 169 (1972)
In the fall of 1969, officials at Central Connecticut State College refused to recognize a radical student group as an official student organization. The students sued, claiming that the school's action violated their First Amendment rights.
In siding with the students, the U.S. Supreme Court noted that "the college classroom and its surrounding environs is peculiarly the 'marketplace of ideas.'"
Its own precedents, the Court said, "leave no room for the view that, because of the acknowledged need for order, First Amendment protections should apply with less force on college campuses than in the community at large. Quite to the contrary, the vigilant protection of constitutional freedoms is nowhere more vital than in the community of American schools."
