Facts
- Charles Kovacs drove through Trenton, New Jersey, using a truck-mounted sound amplifier to broadcast music and speech on public streets.
- A patrolman heard amplified music and a man’s voice; Kovacs admitted operating the amplifier and speaking through it.
- Kovacs was charged under Trenton Ordinance No. 430 § 4, which prohibited operating on public streets any vehicle-attached device that emits “loud and raucous noises,” including sound trucks and loudspeakers, “for advertising purposes, or for any other purpose whatsoever.”
- The record suggested Kovacs may have been commenting on a labor dispute, but the police court record did not formally establish his purpose.
- Kovacs was convicted in the Trenton Police Court; the New Jersey Supreme Court upheld the conviction; the New Jersey Court of Errors and Appeals affirmed by an equally divided court.
Issues
- Whether applying Trenton Ordinance No. 430 § 4 to prohibit operation of a sound truck emitting “loud and raucous noises” on public streets violates the First Amendment, as applied to the states through the Fourteenth Amendment.
- Whether the ordinance is void for vagueness under the Due Process Clause because the phrase “loud and raucous noises” fails to provide adequate notice or enforcement standards.
Decision
- The U.S. Supreme Court affirmed the state-court judgment in a 5–4 decision, upholding Kovacs’s conviction.
- The Court held that, as applied to Kovacs, the ordinance did not violate the First Amendment.
- The Court rejected the vagueness challenge, concluding that “loud and raucous noises” provided a sufficiently definite standard in the context of vehicle-mounted amplifying devices.
- A plurality emphasized governmental authority to regulate the time, place, and manner of expression to protect public peace and comfort.
- Concurring opinions agreed that the special intrusiveness of amplified sound from vehicles justified stronger regulation and that the ordinance regulated noise rather than suppressing ideas.
Legal Principles
- First Amendment protections, though fundamental, are not absolute; government may regulate the hours, place, and manner of public expression.
- A municipality may impose a content-neutral restriction aimed at preventing intrusive street noise and protecting community tranquility, even in traditional public forums, when the restriction targets the method of communication rather than particular ideas.
- The availability of alternative channels of communication supports the reasonableness of a manner restriction (e.g., unamplified speech and printed materials remain available).
- A noise-control standard such as “loud and raucous” may satisfy due process when applied to identifiable conduct (vehicle-mounted amplifiers producing disruptive noise) and when it provides reasonable notice and workable enforcement guidance.
- A generally applicable prohibition grounded in noise control differs from schemes that vest officials with broad discretionary power to permit or forbid expressive sound.
Conclusion
The Court upheld Trenton’s prohibition on sound trucks emitting “loud and raucous” noise on public streets, treating it as a content-neutral regulation of an intrusive mode of expression consistent with the First and Fourteenth Amendments and not unconstitutionally vague as applied.
