Fort Gratiot Sanitary Landfill, Inc. v. Michigan Department of Natural Resources

In Philadelphia v. New Jersey, 437 U. S. 617, 618 (1978), we held that a New Jersey law prohibiting the importation of most “ ‘solid or liquid waste which originated or was collected outside the territorial limits of the State’” violated the Commerce Clause of the United States Constitution. In this case petitioner challenges a Michigan law that prohibits private landfill operators from accepting solid waste that originates outside the county in which their facilities are located. Adhering to our holding in the New Jersey case, we conclude that this Michigan statute is also unconstitutional.
