The defendant was stopped by the police for a violation of a city ordinance prohibiting “unnecessary noise” (a loud car stereo).  The defendant argued that the stop, which resulted in drug charges, was not justified by probable cause because the “unnecessary noise” ordinance is “unconstitutionally vague.” The Fourth Department determined the ordinance was not unconstitutionally vague because it is tailored to the context of what can be heard more than 50 feet from a vehicle on a public highway and is sufficiently definite to put defendant on notice his conduct was forbidden:

Municipal ordinances “enjoy an exceedingly strong presumption of constitutionality’ ” …, and such legislative enactments “are to be construed so as to avoid constitutional issues if such a construction is fairly possible”… . “The void-for-vagueness doctrine embodies a rough idea of fairness’ ” …, and “an impermissibly vague ordinance is a violation of the due process of law” … . In addressing such a challenge, courts first “must determine whether the statute in question is sufficiently definite to give a person of ordinary intelligence fair notice that his [or her] contemplated conduct is forbidden by the statute” … . “Second, the court must determine whether the enactment provides officials with clear standards for enforcement”

* * * … [T]he City Ordinance is not unconstitutionally vague because the section under which defendant was convicted was tailored to a specific context—the creation of “unnecessary noise” beyond 50 feet of a motor vehicle on a public highway (City Ordinance § 40-16 [b]). In our view, “[w]hat is usual noise in the operation of a car [radio or other sound production device] has become common knowledge . . . and any ordinary motorist should have no difficulty in ascertaining” whether the noise in question violates the applicable standard … . Based on the foregoing, we conclude that the ordinance in question was “sufficiently definite” to put defendant on notice that his conduct was forbidden, and that it provided the police “with clear standards for enforcement” … .
