Can the federal government intervene in the affairs of native americans on reservations? if so, when and to what extent?

Although Native Americans have been held to have both inherent rights and rights guaranteed, either explicitly or implicitly, by treaties with the federal government, the government retains the ultimate power and authority to either abrogate or protect Native American rights. This power stems from several legal sources. One is the power that the Constitution gives to Congress to make regulations governing the territory belonging to the United States (Art. IV, Sec. 3, Cl. 2), and another is the president's constitutional power to make treaties (Art. II, Sec. 2, Cl. 2). A more commonly cited source of federal power over Native American affairs is the COMMERCE CLAUSE of the U.S. Constitution, which provides that "Congress shall have the Power … to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes" (Art. I, Sec. 8, Cl. 3). This clause has resulted in what is known as Congress's "plenary power" over Indian affairs, which means that Congress has the ultimate right to pass legislation governing Native Americans, even when that legislation conflicts with or abrogates Indian treaties. The most well-known case supporting this congressional right is Lone Wolf v. Hitchcock, 187 U.S. 553, 23 S. Ct. 216, 47 L. Ed. 299 (1903), in which Congress broke a treaty provision that had guaranteed that no more cessions of land would be made without the consent of three-fourths of the adult males from the Kiowa and Comanche tribes. In justifying this abrogation, Justice EDWARD D. WHITE declared that when "treaties were entered into between the United States and a tribe of Indians it was never doubted that the power to abrogate existed in Congress, and that in a contingency such power might be availed of from considerations of governmental policy."
