I think Danno's on the right track, if there is one. Found this on a DOJ site:
II. PRINCIPLES OF INDIAN SOVEREIGNTY AND THE TRUST RESPONSIBILITY
Though generalizations are difficult, a few basic principles provide important guidance in the field of Indian affairs: 1) the Constitution vests Congress with plenary power over Indian affairs; 2) Indian tribes retain important sovereign powers over their members and their territory, subject to the plenary power of Congress; and 3) the United States has a trust responsibility to Indian tribes,which guides and limits the Federal Government in dealings with Indian tribes. Thus, federal and tribal law generally have primacy over Indian affairs in Indian country, except where Congress has provided otherwise.

And in another legal paper:
"In light of the history of treaty-making and with an eye toward restoring the sense of equality between nations that justified the treaty process to begin with, American Indians are -- in concert with indigenous peoples worldwide -- asserting a sense of their own "sovereignty." The United Nations Draft Declaration of the Rights of Indigenous Peoples is at the center of this global struggle for self-determination. The Declaration is the product of twenty years of negotiating among indigenous peoples and U.N. bodies. It's very title draws the line of battle -- rights of indigenous peoples (plural).
^^^^^^^^^^^^^^^^^^what Chief Tipp was saying.
Federal Indian Law:
When we enter into the realm of "federal Indian law," we need to keep in mind that we are traveling in a semantic world created by one group to rule another. "
Was found in AMERICAN INDIAN SOVEREIGNTY:NOW YOU SEE IT, NOW YOU DON'T at http://www.umass.edu/legal/derrico/nowyouseeit.html, which appears to be a pretty comprehensive study.
And I still don't really get it...:confused:
