ORDER AND JUDGMENT TACHA, Chief Judge. After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. Plaintiff Edson Gardner appeals the dismissal of his lawsuit against various Ute tribal entities and representatives. Because plaintiff has not shown federal court jurisdiction over his claims, we affirm. Plaintiff filed a series of pleadings in the district court.
In February 2000, he attempted to file documents entitled “Extraordinary Writ and Mandamus” and “Amendment Extraordinary Writ and Mandamus.” In these documents, plaintiff alleged that he, a mixed-blood Uintah Indian, holds a possessory interest in the Uin-tah Valley in Utah based on an 1861 treaty, and that the Ute Tribe was wrongfully possessing and transferring the land. These pleadings were not filed, however, because plaintiff failed to pay the filing fee.
On September 7, 2000, plaintiff paid the filing fee and filed a document entitled “Petition for Writ of Habeas Corpus and Evidentiary Hearing Requested.” In his petition, plaintiff alleged that he was in the custody of the Ute tribal court based on the court’s letters admonishing him against the unauthorized practice of law and forbidding him from practicing in the tribal court because he lacked a law license and was not a member of a federally recognized tribe. Plaintiffs February pleadings were also deemed filed at this time.
After reviewing plaintiffs pleadings, the district court concluded they failed to state a claim. Plaintiff was directed to file an amended complaint clearly setting forth his claims and the facts underlying the claims. Plaintiff responded by filing a pleading containing new claims under
section 2 of the Voting Rights Act of 1965. Plaintiffs amended complaint alleged that the Ute Tribe’s system of election improperly disenfranchised mixed-blood Uintah Indians, and sought declaratory and in-junctive relief. Defendants moved for dismissal on both jurisdictional and procedural grounds. After reviewing plaintiffs amended complaint, the district court granted defendants’ motions to dismiss.
On appeal, plaintiff argues that the district court erred in dismissing his “habeas” action because he raised a federal question regarding his possessory rights to the Uin-tah Valley, and a constitutional question regarding his inability to practice in the tribal court. He also argues for the first time on appeal that the Tribe subjected him to employment discrimination. We do not consider this issue, however, because it was not presented to the district court. Crow v. Shalala, 40 F.3d 323, 324 (10th Cir.1994). We begin by examining our jurisdiction, as we are required to do. Bender v. Williamsport Area Sch.
Dist., 475 U.S. 534, 541, 106 S.Ct. 1326, 89 L.Ed.2d 501 (1986) (holding “every federal appellate court has a special obligation to satisfy itself ... of its own jurisdiction”) (quotation omitted). We have jurisdiction under 28 U.S.C. § 1291 to review the district court’s conclusion that it lacked subject matter jurisdiction. See Robinson v. Union Pac. R.R., 245 F.3d 1188, 1190 (10th Cir.2001). We review the district court’s dismissal de novo. E.F.W. v. St. Stephen’s Indian High Sch., 264 F.3d 1297, 1303 (10th Cir.2001).
Plaintiff has the burden of demonstrating the existence of subject matter jurisdiction by a preponderance of the evidence. Robinson, 245 F.3d at 1191. The Ute Indian Tribe is a sovereign entity which may not be sued in federal court unless its immunity has been clearly waived either by the Tribe or by Congress. Id. at 1304. Plaintiff has not shown such a waiver for any of his claims. Moreover, as plaintiff is not in “custody” as that word is defined in habeas case law, there is no jurisdiction over his habeas claim. See Maleng v.
Cook, 490 U.S. 488, 490-91, 109 S.Ct. 1923, 104 L.Ed.2d 540 (1989) (noting that federal court has habeas jurisdiction “only” when person requesting relief is in custody). Finally,
section 2 of the Voting Rights Act, by its terms, does not apply. See 42 U.S.C.1973(a) (limiting provisions of statute to States and their political subdivisions). The judgment of the United States District Court for the District of Utah is AFFIRMED. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. The court generally disfavors the citation of orders and judgments; nevertheless, an order and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
