Immunity Federal sovereign immunity Because of the ease with which the federal government may extinguish aboriginal title, and the fact that it may constitutionally do so without compensation, meritorious claims against the federal government are difficult to construct.
Federal Power Commission v. Tuscarora Indian Nation (1960) held that the Nonintercourse Act did not apply to the federal government. Additionally, the federal government cannot be sued without its consent. The federal government has consented to some compensatory suits under the Indian Claims Commission Act, supra, subject to a statute of limitations. Nor can the states sue the federal government in its capacity as guardian of the tribes. Prior to the ICCA,
private bills waived sovereign immunity for specific tribal complaints. The ICCA, and its amendments, also created a statute of limitations for claims against the federal government. ;State sovereign immunity was unable to sue Idaho to recover
Lake Coeur d'Alene due to state sovereign immunity; The
Eleventh Amendment, and the broader principle of state sovereign immunity derived from the structure of the Constitution, bars most suits against states without their consent. Although states may sue other states, the Supreme Court ruled in
Blatchford v. Native Vill. of Noatak (1991) that tribes—even though they also enjoy sovereign immunity—have no greater ability to sue states than private individuals. There are several exceptions to state sovereign immunity potentially relevant to aboriginal title claimants: the doctrine of
Ex parte Young (1908), Congressional abrogation of state sovereign immunity by statute, and the ability of the federal government itself to sue states. While—under
Ex parte Young—tribes may obtain some prospective, equitable relief in suits nominally against state officials (generally, for treaty rights), the Supreme Court in ''
Idaho v. Coeur d'Alene Tribe (1997) held that state sovereign immunity barred not only quiet title suits but also suits against state officials which would constitute the equivalent of quiet title. Although Coeur d'Alene'' involved sovereign title to a lake bed, this precedent has been applied to bar even suits against states in their capacity as ordinary property owners. There are at least two Congressional statutes which may have contemplated authorizing aboriginal title suits against states: the
Nonintercourse Act and 28 U.S.C. § 1362, providing: "district courts shall have original jurisdiction of all civil actions, brought by any Indian tribe or band with a governing body duly recognized by the Secretary of the Interior, wherein the matter in controversy arises under the Constitution, laws, or treaties of the United States." The Supreme Court rejected the latter in
Blatchford, supra; the
Fifth Circuit rejected the former in 2000. The Supreme Court mooted both in
Seminole Tribe v. Florida (1996)—a suit under the
Indian Gaming Regulatory Act—when it held that Congress could not constitutionally abrogate state sovereign immunity under the
Indian Commerce Clause, the basis for both statutes. This holding has subsequently been expanded to nearly all of Congress's
Article One powers, leaving only the
Reconstruction Amendments as a basis for abrogating state sovereign immunity. Finally, the federal government may bring suits against states on behalf of the tribes in its guardian capacity, as it historically has. Similarly, tribes may
intervene in suits brought by the federal government (or the federal government may intervene in suits brought by the tribes) against states. This exception is rather narrow, and states may assert sovereign immunity where tribes assert different claims, or ask for different relief, than the federal government. State statute of limitations do apply, however, for tribal actions under state law, such as
quiet title, even if based on aboriginal title. Similarly, the Supreme Court in 1907 declared that, for the sake of stability in property law, that it would defer to state court interpretations of Indian treaties.
Laches In
Oneida II, the four dissenting justices would have applied
laches to dismiss the claim. which held that
laches "cannot properly have application to give vitality to a void deed and to bar the rights of Indian wards in lands subject to statutory restrictions." Building on
Sherrill, the
Second Circuit in
Cayuga Indian Nation of N.Y. v. Pataki (2005) held that "these equitable defenses apply to 'disruptive' Indian land claims more generally." Although the
Solicitor General joined the Cayugas' appeal, the Supreme Court denied certiorari. The Second Circuit has also applied
laches to non-possessory contract claims for
unconscionable consideration. This doctrine has been criticized for not requiring the defendant to satisfy the traditional elements of the
laches defense, applying only to Indian land claims, and having the potential to bar nearly all Indian land and treaty claims. No other Circuit has adopted the Second Circuit's expansive view of
Sherrill. The
Third,
Sixth,
Eighth, and
Tenth Circuits, since
Sherrill, have declined to reach the question of the scope of
laches as a defense to ancient tribal claims. The
First Circuit has limited
Sherrill to assertions of sovereignty, in an opinion that was reversed on other grounds. Some
district courts take the First Circuit's view; others the Second Circuit's; others strike a middle ground. ==Relationship to other rights==
