I would point out that while the US Constitution's Bill of Rights does not
apply to the actions of an Indian Tribal Government within its own Indian
Country, the Indian Civil Rights Act of 1968, 26 USC ss 1301, et seq. does.
The ICRA extends most of the provisions of the Bill of Rights to the actions
of Tribal Government. The major exceptions are that the ICWA does not
provide for any right to bear arms (who in the federal government would make
sure that Indians are armed??) and there is no religious "establishment
clause" prohibiting a tribal government from establishing an official tribal
religion (due to the fact that many _traditional_ tribal governments are
spiritually based or operated by the tribal religious leadership, even some
"elective systems" include all or portions of their traditional governmental
system as a part of their tribal government today). That legislation also
provides that any individual detained by a Tribal government may challenge
that detention via a Writ of Habeus Corpus in the Federal District Court.
