Michigan’s Solid Waste Management Act (SWMA) generally prohibited Michigan counties from accepting for disposal solid waste that had been generated outside that county. Fort Gratiot operated a sanitary landfill in St. Clair County, Michigan. The county denied Fort Gratiot permission to bring in solid waste from out of state, and Fort Gratiot sued. This case involves the negative, or dormant, aspect of the Commerce Clause. What is the difference between that aspect and the positive aspect? What is the evil that the dormant aspect is designed to avoid? How would you rule in this case?
