Heading: Congress's Abrogation of the Tribe's Rights

Text: 56 If the district court determines that the 1867 Treaty or subsequent congressional acts have invested the Tribe with the authority to regulate electric services on the Reservation, the district court should then determine whether later congressional action has abrogated that authority. The district court should keep in mind that Congress can abrogate the Tribe's treaty rights, but must do so explicitly. See South Dakota v. Bourland, --- U.S. ----, ---- - ----, 113 S.Ct. 2309, 2315-16, 124 L.Ed.2d 606 (1993); cf. Montana v. United States, 450 U.S. 544, 560-61, 101 S.Ct. 1245, 1256, 67 L.Ed.2d 493 (1981) (examining effect of subsequent alienation of land on exclusive use language of prior treaty).
