33 Joint Memorandum in Support of Plea Agreement
36 Magistrate Minute Order: “This Court does not have jurisdiction over the charge in the proposed Plea Agreement. . . .”
An excerpt:
The Major Crimes Act represents one way in which Congress has permitted federal courts to exercise jurisdiction over crimes occurring on tribal lands which otherwise would be subject to the exclusive jurisdiction of the tribal courts. Now codified at 18 U.S.C. § 1153, the Act gives federal courts exclusive federal jurisdiction over certain enumerated felonies occurring between Indians in Indian Country, including, specifically, “a felony assault under section 113.” 18 U.S.C.A. § 1153(a). See also United States v. Burch, 169 F.3d 666, 669 (10th Cir. 1999). Prosecution of crimes not expressly designated in section 1153, including, specifically, simple assault – is reserved to the tribal courts, in recognition of their inherent sovereignty over such matters. United States v. Antelope, 430 U.S. 641, 643 n.1, 97 S.Ct. 1395, 1397 n.1, 51 L.Ed.2d 701 (1977); United States v. Quiver, 241 U.S. 602, 700-01, 36 S.Ct. 699, 605-06, 60 L.Ed. 1196 (1916); United States v. Burch, 169 F.3d 666, 668-69 (10thCir. 1999). See also United States v. Lara, 541 U.S. 193, 199, 124 S.Ct. 1628, 1632-33, 158 L.Ed.2d 420 (2004) (“[25 U.S.C. § 1301] says that it ‘recognize[s] and affirm[s]’ in each tribe the ‘inherent’ tribal power … to prosecute nonmember Indians for misdemeanors.”).
