On 9 January 2001 the US Supreme Court, in a split vote of 5 to 4, ("Solid Waste Agency, of Skokie, Illinois vs US Army Corps of Engineers") threw out what has been dubbed the migratory bird rule. A case that pitted a consortium of towns around Chicago over isolated wetlands, inhabited or visited by over 100 migratory bird species, against the US Army Corps of Engineers. In this case, Skokie, Illinois, wanted abandoned quarries filled with water, but not connected to another or navigable body of water to serve as a site for a solid waste facility. For the previous 15 years, lower courts had sustained the law in favor of migratory birds, siding with the Army Corps.
