Justice
William O. Douglas delivered the opinion of the Court, writing: We hold that 3 of this ordinance is unconstitutional on its face, for it establishes a previous restraint on the [334 U.S. 558, 560] right of free speech in violation of the First Amendment which is protected by the Fourteenth Amendment against State action. To use a loud- speaker or amplifier one has to get a permit from the Chief of Police. There are no standards prescribed for the exercise of his discretion. The statute is not narrowly drawn to regulate the hours or places of use of loud-speakers, or the volume of sound (the decibels) to which they must be adjusted. The ordinance therefore has all the vices of the ones which we struck down in Cantwell v. Connecticut, 310 U.S. 296, 128 A.L.R. 1352; Lovell v. Griffin, 303 U.S. 444; and Hague v. C.I.O., 307 U.S. 496. ==See also==
