Here are the materials in Columbe v. Rosebud Sioux Tribe (D. S.D.):
Colombe now asks this Court to rule on the sole remaining issue from this Court’s September 23, 2011 Opinion and Order: Whether the Tribal Court had jurisdiction to hold that the oral modification to the NIGC-approved management contract was void. Colombe argues that the NIGC has the sole, exclusive authority to determine whether modifications to NIGC-approved management contracts can have any legal effect. Doc. 49 at 6-7. Colombe also argues that Defendants’ Tribal Court suit is prohibited because IGRA does not authorize a private cause of action. Doc. 49 at 8. Defendants counter that the Rosebud Sioux Tribal Supreme Court had jurisdiction to rule on the legal validity of the oral, unapproved modification to the approved management contract after Colombe raised the modification as a defense in the Tribe’s underlying contract suit. Doc. 59; Doc. 60. Defendants also assert that its Tribal Court suit is not for a “claimed IGRA violation” and therefore does not need to be authorized by the IGRA. Doc. 57 at 19.
