Invoking the lyrics of the pop singer Christopher Cross, a Manhattan judge has ruled that a section of the New York City Administrative Code that prohibits towing aerial advertising banners is unconstitutional.

Criminal Court Judge Arthur M. Schack, who began his decision in People v. Alex Santoriello with the refrain from Mr. Cross’s 1979 hit “Sailing,” found that the ordinance must be struck down because it entirely proscribes behavior permitted by the Federal Aviation Administration (FAA).
