People v. Altman
Paul Altman was charged with violating a Town of Hempstead ordinance prohibiting seaplanes from landing or taking off in the channel system. Altman admitted to two violations in Reynolds Channel. He argued that federal law preempted local governments from regulating airways and seaplane ways, and that the ordinance unconstitutionally burdened interstate commerce. The court found that the ordinance was in harmony with federal law and a proper exercise of the Town's police power, noting a strong presumption of constitutionality for legislative enactments. The court found the defendant guilty.
