 "Durousseau v. United States", 10 U.S. 307 (1810) held that Congress's affirmative description of certain judicial powers implied a negation of all other powers.Creating such legislation was legitimate under the authority granted them by the United States Constitution.By repealing the act that granted the Supreme Court authority to hear the case, Congress made a clear statement that they were using this Constitutional authority to remove the Supreme Court's jurisdiction.
