Wisconsin v. Illinois, 278 U.S. 367 (1929), also referred to as the Chicago Sanitary District Case, is an opinion of the Supreme Court of the United States which held that the equitable power of the United States can be used to impose positive action on one state in a situation in which nonaction would result in damage to the interests of other states.^[1] Pursuant to Article Three of the United States Constitution, the case was heard under the Supreme Court's original jurisdiction (i.e. it did not come to the Supreme Court from a lower court) because it involved a controversy between two states, Illinois and Wisconsin. Chief Justice William Howard Taft wrote the opinion for a unanimous Court.
