Grayned v. City of Rockford
Argued January 19, 1972
Decided June 26, 1972
408 U.S. 104
1. Anti-picketing ordinance, virtually identical with one invalidated as violative of equal protection in Police Department of Chicago v. Mosley, ante, p. 408 U. S. 92, is likewise invalid. P. 408 U. S. 107.
2. Anti-noise ordinance prohibiting a person while on grounds adjacent to a building in which a school is in session from willfully making a noise or diversion that disturbs or tends to disturb the peace or good order of the school session is not unconstitutionally vague or overbroad. The ordinance is not vague, since, with fair warning, it prohibits only actual or imminent, and willful, interference with normal school activity, and is not a broad invitation to discriminatory enforcement. Cox v. Louisiana, 379 U. S. 536; Coates v. Cincinnati, 402 U. S. 611, distinguished. The ordinance is not overbroad as unduly interfering with First Amendment rights since expressive activity is prohibited only if it "materially disrupts classwork." Tinker v. Des Moines School District, 393 U. S. 503, 393 U. S. 513. Pp. 408 U. S. 107-121.
