What important Supreme Court case involved the Oklahoma Indian Welfare Act?

The Supreme Court case that involved the Oklahoma Indian Welfare Act is significant because it directly addressed issues pertaining to Native American self-governance and the rights of tribes. The Oklahoma Indian Welfare Act was enacted in 1936 to restore a measure of self-governance and economic self-sufficiency to Native American tribes in Oklahoma after years of federal assimilation policies.

United States v. John Johnson specifically examined the implications of the Oklahoma Indian Welfare Act regarding tribal membership and governance. The case dealt with the effort to reaffirm the rights of tribes to control their own affairs, including who qualifies for membership, which is a crucial aspect of tribal sovereignty. The ruling affirmed the importance of tribal authority and the federal government's commitment to supporting Native American communities in regaining control over their governance structures.

The other cases listed do not pertain to Native American rights or the specific provisions of the Oklahoma Indian Welfare Act, focusing instead on different legal and constitutional issues.
