This case concerns whether an Indian tribe can exercise criminal jurisdiction over a person who is not a member of the tribe, but who is an enrolled member of another Indian tribe.

Facts

This is an appeal from a denial of a petition for a writ of habeas corpus. The petitioner, Russell Means, a member of the Oglala-Sioux Indian Tribe, seeks to prevent the Navajo Nation from criminally prosecuting him in Navajo tribal court for an incident that occurred on the Navajo Reservation.

In December 1997, Means allegedly threatened and battered his then father-in-law, who is an Omaha Indian, and allegedly threatened another man, a Navajo Indian. The offenses are misdemeanors under the Navajo Code, with potential maximum penalties of 90 days in jail and a $250 fine for each threatening, and 180 days in jail and a $500 fine for the battery.

Means moved in the Navajo tribal court to dismiss the tribal proceedings. He argued that because he was not a Navajo, the tribal court had no jurisdiction. Means testified that he is a member of the Oglala-Sioux Tribe of Indians, and a permanent resident of Porcupine, a town in South Dakota on the Pine Ridge Sioux Indian Reservation. Means lived on the Navajo Indian Reservation from 1987 to 1997 when he was married to a woman who was a half-Navajo, half-Omaha Indian. Means moved back to the Sioux reservation that year, and the alleged offenses occurred later when Means was visiting the Navajo reservation.

Means testified that the difference between an Oglala-Sioux and a Navajo is as different as an American and a French person. Although Means lived on the Navajo reservation for a decade while married to his ex-wife, he could never become a member of the Navajo tribe because membership required at least one quarter Navajo blood. Means does not speak Navajo, and as a non-Navajo, he had difficulty obtaining employment because of tribal preferences given to Navajos and restrictions that make it difficult for a non-Navajo to find employment, participate in civic life, and license a business.

The Navajo Nation trial court denied Means’s motion to dismiss for lack of jurisdiction. Means appealed to the Navajo Nation Supreme Court which also denied his motion. The decision of the Navajo Nation Supreme Court explains that the Navajo reservation covers about 25,000 square miles, making it larger than many U.S. states and foreign countries. Over 9,000 Indians of other tribes live within the Navajo Nation, so domestic violence cases involving non-Navajo Indians arise from time to time. The Navajo Supreme Court explained that the considerable amount of violence arising from alcohol, when combined with the size and ethnic inclusiveness of the reservation, generates a “need to exercise criminal jurisdiction over all who enter the Navajo Nation,” not just Navajo Indians. The Navajo Supreme Court decision says that while there are preferences for Navajos in employment and contracting, they are not absolute barriers, and that Means could have qualified for jury service in the Navajo tribal courts had he been registered to vote in Arizona. The Navajo Supreme Court also noted that because Means had married a Navajo, during his residence on the reservation he was a “hadane,” or in-law, connected by rights and obligations to his wife’s clan. As the Navajo Supreme Court notes, however, becoming a “hadane” does not make one a Navajo.

After exhausting his remedies in the Navajo courts, Means petitioned the United States District Court for a writ of habe-as corpus to enjoin the tribal courts from proceeding further in his case. The district court denied Means’s petition, and he appeals.

Analysis

All the questions before us are purely matters of law, and arise on appeal of the district court’s denial of a writ of habeas corpus under 25 U.S.C. § 1303 , so we review de novo.

I. Jurisdiction

Means has exhausted his tribal court remedies regarding jurisdiction, but he has still not been tried for the alleged threats and battery. Nonetheless, Means remains subject to conditions of pretrial release. Means cannot have any contact with his former father-in-law or go within 100 yards of his former father-in-law’s home. Means also must appear as ordered by the Navajo trial court or face rearrest and additional punishment for any failure to appear. The district court therefore concluded that Means was in custody for purposes of habeas jurisdiction under Justices of Boston Municipal Court v. Lyd on and Hensley v. Municipal Court. The parties have not challenged that conclusion before us, and, although we are required to examine jurisdiction sua sponte, we agree with the district court. The charges against Means remain pending in the Navajo Nation trial court, and although the Navajo Nation and Means have stipulated to a stay in the trial court until this appeal is decided, the Navajo Nation states that it fully intends to prosecute Means if jurisdiction is resolved in its favor. Accordingly, we have jurisdiction to consider this appeal.

II. The 1990 Amendments to the Indian Civil Rights Act

In Oliphant v. Suquamish Indian Tribe, the Supreme Court held that Indian tribes do not possess criminal jurisdiction over non-Indians. In Oliphant, the Suquamish Tribe had prosecuted two non-Indians, one for racing down a highway and colliding with a tribal police car, another for assaulting an officer and resisting arrest. The tribe did not claim that Congress had given it authority to exercise jurisdiction, but rather that the tribe had an inherent sovereign authority to exercise criminal jurisdiction over incidents that occurred on its reservation — an authority that Congress had never taken away. The Supreme Court disagreed and held that, although Indian tribes enjoy some sovereign powers, the “domestic, dependent” nature of tribes distinguishes tribal governments from the governments of foreign countries, and that citizens of the United States who are not Indians cannot be subjected to Indian tribal sovereignty for criminal purposes.

Following Oliphant, the Supreme Court suggested in United States v. Wheeler that the inherent sovereignty of a tribe might extend only to its own members. Then, in Duro v. Reina, the Court explicitly held that “the retained sovereignty of the tribe as a political and social organization to govern its own affairs does not include the authority to impose criminal sanctions against a citizen outside its own membership.” Duro reasoned that, as American citizens, Indians were entitled not to be subjected to the criminal authority of sovereignties of which they were not and could not become members.

In 1990 Congress responded to Indian tribes’ concerns about the holding in Duro by amending the Indian Civil Rights Act to say that the “powers of self-government” of Indian tribes “means the inherent power of Indian tribes, hereby recognized and affirmed, to exercise criminal jurisdiction over all Indians.” “All Indians” plainly includes Indians who are not members of the tribe. It is significant for the equal protection discussion below, however, that the 1990 Amendments do not cover anyone who might ethnically be an Indian but who is not an enrolled member of a federally recognized tribe. In addition to extending tribal criminal jurisdiction to “all” Indians, the 1990 Amendments make it plain that the definition of “Indian” is the same as “Indian” in the Major Crimes Act.

The 1990 Amendments define “Indian” as “any person who would be subject to the jurisdiction of the United States as an Indian under section 1153, Title 18, if that person were to commit an offense listed in that section in Indian country to which that section applies.” The statute referred to, 18 U.S.C. § 1153 (the Major Crimes Act), says it applies to “[a]ny Indian,” but has been construed by the Supreme Court in United States v. Antelope to mean only those persons who are enrolled members of a tribe — not persons who are by blood “Indian.” Taken together, the 1990 Amendments, the Major Crimes Act, and Antelope mean that the criminal jurisdiction of tribes over “all Indians” recognized by the 1990 Amendments applies only to Indians who are enrolled members of a recognized tribe, not persons who are merely ethnically Indians.

Means argues that the 1990 Amendments were outside the powers of Congress because they were an unconstitutional delegation of federal governmental authority, and because they went beyond the congressional power authorized under the Indian Commerce and Treaty Clauses. Indian tribes are not bound by the United States Constitution in the exercise of their powers, including their judicial powers, so federal judicial power over nonmembers could not be delegated to them.

Following the 1990 Amendments, Means’s theory was tested in other cases. Double jeopardy cases tested whether the statutory language, “recognizpng] and affirm[ing]” the power of tribes over nonmember Indians rather than “delegating” it, avoided double jeopardy problems when both a tribe and the federal government punished someone for the same conduct. If the tribe was exercising its inherent sovereign authority, an Indian defendant could be punished in both the tribal court as well as in federal district court under the “dual sovereignty” doctrine. If the tribe was exercising delegated federal power, then the federal government would be punishing the Indian twice for the same conduct, which it could not do under the double jeopardy clause. More broadly, after the Supreme Court in Duro had concluded that the tribe had not retained sovereign power over nonmember Indians, the question was whether Congress even had the ability to “recognize” an inherent power.

These questions raised by Means’s statutory argument have, subsequent to the original briefing in this case, been definitively answered by the Supreme Court. United States v. Lara holds that “Congress does possess the constitutional power to lift the restrictions on the tribes’ criminal jurisdiction over nonmember Indians as the statute seeks' to do.” As for whether the tribe’s exercise of criminal jurisdiction was a delegated, or an inherent sovereign power, the Court held, with certain reservations, that “the Constitution permits tribes, as an exercise of their inherent tribal, authority, to prosecute non member Indians.” Thus, except for the questions reserved in Lara, it is settled law that, pursuant to the 1990 amendment to the Indian Civil Rights Act, an Indian tribe may exercise inherent sovereign judicial power in criminal cases against nonmember Indians for crimes committed on the tribe’s reservation.

III. Equal Protection and Due Process

A. Equal Protection

Lara expressly declined to answer the question of whether the tribal criminal prosecution of a nonmember Indian would violate the Due Process and Equal Protection guarantees of the Fifth Amendment. Means argues that by recognizing tribal criminal jurisdiction over nonmember Indians, the 1990 Amendments violate the equal protection guarantees of the Fifth Amendment and the Indian Civil Rights Act because they discriminate against him as an Indian, subjecting him to adverse treatment on account of his race.

Means’s equal protection argument has real force. He argues that although the 1990 Amendments permit the Navajo tribe to criminally prosecute its own members and members of other Indian tribes, the Navajo cannot constitutionally prosecute whites, blacks, Asians, or any other non-Navajos who are accused of crimes on the reservation. This makes Means’s case different from, say, an Alaskan who threatens and batters his father-in-law in Los Angeles, and then is prosecuted by the State of California. Not only can an Alaskan become a Californian, but the State of California, although “sovereign,” nonetheless is bound by the Due Process and Equal Protection Clauses of the Fourteenth Amendment. Although he is an Indian, Means is nonetheless a citizen of the United States, entitled to the full protection of the United States Constitution. But unlike states, when Indian tribes exercise their sovereign authority they do not have to comply with the United States Constitution. As an Oglala-Sioux, Means can never become a member of the Navajo political community, no matter how long he makes the Navajo reservation his home.

Despite the force of Means’s argument, we nonetheless conclude that the weight of established law requires us to reject Means’s equal protection claim. Morton v. Mancari holds (albeit in the distinguishable context of Indian employment preferences by the federal government) that federal statutory recognition of Indian status is “political rather than racial in nature.” Means argues that Mancari is undermined by Adarand Constructors, Inc. v. Pena, but both the Supreme Court and our court have continued to rely on Mancari, and we are bound to follow it under the doctrine of Agostini v. Felton.

Mancari held that an employment preference for Indians in the Bureau of Indian Affairs was not “invidious racial discrimination in violation of the Due Process Clause of the Fifth Amendment” because “it is not even a ‘racial’ preference.” “[L]egislation that singles out Indians for particular and special treatment” is in a special category because of the historical relationship of the United States with the Indians and the Indian Commerce Clause, and “[a]s long as the special treatment can be tied rationally to the fulfillment of Congress’ unique obligation toward the Indians, such legislative judgments will not be disturbed.” The preference at issue passed this “rational tie” standard, because “the preference is reasonable and rationally designed to further Indian self-government.”

We conclude that a law subjecting nonmember Indians to tribal criminal jurisdiction in “Indian country” passes the “rational tie” standard of Mancari. First, recognizing criminal jurisdiction of tribal courts over nonmember Indians furthers Indian self-government. The Navajo reservation, larger than many states and countries, has to be able to maintain order within its boundaries. The 1990 Amendments to the Indian Civil Rights Act were meant to protect Indians, as well as others who reside in or visit Indian country, against lawlessness by nonmember Indians who might not otherwise be subject to any criminal jurisdiction. As the Navajo Supreme Court notes, because of intermarriage there are a significant number of Indians who are not Navajos but live on the Navajo reservation. It is a matter of ordinary experience that many people are not at their best when their marriages break up, so misdemeanor jurisdiction over nonmember Indians is rationally related to Indian self-government in an area where rapid and effective tribal response may be needed. The Navajo Nation has a sophisticated body of published laws, and an experienced court system in which trained trial and appellate judges adjudicate thousands of cases per year. If Means was not subject to prosecution in the Navajo courts, he would not be prosecuted in any court since the state of Arizona, like the majority of states, does not have jurisdiction to try Indians for offenses committed on a reservation, and there is no federal court jurisdiction since Means’s alleged offenses do not fall within the Major Crimes Act.

Second, the reason Congress can recognize the power of a tribe to exercise criminal jurisdiction over a nonmember Indian like Means — but not over a nonmember, non-Indian who like Means might become involved in a domestic dispute — is the same reason given by the Supreme Court for the employment preference in Man-can: Indian tribal identity is political rather than racial, and the only Indians subjected to tribal court jurisdiction are enrolled members of tribes, not all ethnic Indians.

In United States v. Antelope, Indians who were enrolled members of the Coeur d’Alene Tribe challenged the applicability of federal law to a prosecution for a murder that had taken place on the tribe’s reservation. Had they been of a different race, they argued, a more favorable provision of state law would have applied under the Assimilative Crimes Act, rather than the less favorable federal provision that applied under the Major Crimes Act. But the Supreme Court noted its holding in Mancan that the employment preference was granted to Indians “not as a discrete racial group, but rather, as members of quasi-sovereign political entities,” and extended Mancan, even though the context did not involve Indian self-government. The Court found that the respondents were subjected to federal law “not because they are of the Indian race but because they are enrolled members of the Coeur d’Alene tribe.”

There is no sound distinction in principle between Antelope and this case. The statute subjects Means to Navajo criminal jurisdiction, not because of his race, but because of his political status as an enrolled member of an Indian tribe, even though it is a different tribe than the one that seeks to assert jurisdiction over him. We need not decide whether the same principle would apply if Means were ethnically Indian but not an enrolled member of any tribe, or if prior to committing the alleged misdemeanors he had formally withdrawn from his tribe, because those hypothetical facts are not claimed in this case.

B. Due Process

Because the criminal proceedings against Means in the Navajo trial court have been stayed pending the out come of his jurisdictional challenge, an “as applied” due process challenge to the Navajo trial proceedings would be premature. Means’s facial due process challenge to the 1990 Amendments has no force. Although the U.S. Constitution does not bind the Navajo tribe in the exercise of its own sovereign powers, the Indian Civil Rights Act confers all the criminal protections on Means that he would receive under the Federal Constitution, except for the right to grand jury-indictment and the right to appointed counsel if he cannot afford an attorney. The right to grand jury indictment would not pertain regardless, because Means is charged with a misdemeanor. The right to appointed counsel is conferred by the Navajo Bill of Rights to any person within its jurisdiction. Thus as a facial matter, Means will not be deprived of any constitutionally protected rights despite being tried by a sovereign not bound by the Constitution.

IV. The Treaty of 1868

The war between the United States and the Navajo Nation, which began in the middle of the U.S. Civil War, ended in 1868 with a treaty, signed on behalf of the United States by General William Tee-umseh Sherman. Means argues that under the terms of this treaty, he may not be criminally prosecuted by the Navajo tribe, but must be turned over to the federal government for trial.

Means bases his argument on the so-called “bad men” clauses of the 1868 Treaty. Indian tribes warred, not only with the federal government, but also with other tribes. Guaranteeing that the Indians would return to a peaceful way of life, therefore, required some means of dealing with the hostile foreign tribes.

One clause in the 1868 Navajo Treaty— which is identical to language used in a number of Indian Treaties of the time— says that

A second clause, speaking expressly about Indians, is analogous:

Means argues that even if the Navajo Nation at one time possessed the sovereign power to assert criminal jurisdiction over nonmember Indians, it relinquished that right by entering into the 1868 Treaty, which requires that the Navajo Tribe deliver the wrongdoer to the United States, to be tried and punished according to federal, not Indian, law. Means also argues that the 1990 Amendments to the Indian Civil Rights Act cannot abrogate the protections to which he is entitled under the 1868 Treaty because Congress has never expressly abrogated the treaty.

The Navajo Nation, however, argues that a discussion between General Sherman and the Navajo Chief Barboncito during the treaty negotiations expresses an understanding that the Navajo were entitled to “drive out” raiders from the Ute and Apache tribes who might molest them, and that the Indian “bad men” clause therefore meant to confer jurisdiction over nonmember Indians, not to remove it. The Navajo Nation also suggests that we are bound to defer to the understanding of the treaty expressed well over a century after its adoption by the Navajo Nation Supreme Court. That court found that the 1868 Treaty provides for criminal jurisdiction over Means because he entered the Navajo Nation, married a Navajo woman, and engaged in business and civic activities while residing on the reservation.

We accept neither argument because the 1868 Treaty does not conflict with, and is easily reconciled with, the language of the 1990 Amendments to the Indian Civil Rights Act that recognizes the inherent sovereign power of the tribe. A common sense understanding of the treaty language would be that the United States was obligating itself to protect the Navajos from “bad men,” of whom the world is never short, and the Navajos were obligating themselves to turn the “bad men” over to the United States when appropriate under the specified conditions. The treaty obligates the United States to arrest and punish offenders against the Navajo, under federal law, but it does not say that the Navajo cannot do so on their own, and there is nothing in the treaty language inconsistent with the concurrent jurisdiction that we have recognized in other contexts.

The remedies provided for by the 1868 treaty do not purport to be exclusive. Under the treaty, Indian offenders are to be delivered to the United States for prosecution under federal law on request. This provision, however, is conditioned on a request from the United States’s agent. The treaty conditions have not been fulfilled in this case, so the rendition provision in the treaty does not apply. The United States has not demanded that the Navajo turn Means over for federal prosecution, and the Navajo have chosen to prosecute Means themselves in tribal court, which the 1990 Amendments to the Indian Civil Rights Act recognize they have the power to do.

Conclusion

The Navajo Nation is empowered, under the 1990 Amendments, to prosecute and punish Indians for misdemeanors, despite their status as nonmembers of the tribe. The denial of Means’s petition for a writ of habeas corpus is
