From the Indigenous Policy Journal’s Winter 2010 issue (link to article here).
The article, titled “The Treaty Basis of Michigan Indian Education,” was authored by Martin Reinhardt and John Tippeconnic, III.
Here’s the abstract:
A socio-historical content analysis of 16 treaties and 3 contemporary American Indian education laws at the federal level revealed that a certain amount of the treaty obligation may yet be unfulfilled regarding tribes currently located within the State of Michigan. Both monetary and non-monetary provisions were analyzed using the United States Supreme Court’s Canons of Treaty Construction. The treaty provisions were further categorized according to certain criteria based on the trust doctrine. The outcomes of the treaty analysis were then compared to the provisions of the Indian Education Act, the Indian Self-Determination & Education Assistance Act, and the Individuals with Disabilities Education Act. Responsibilities of each level of government, implications for school policy and procedures, and recommendations for further study are included.

American Indians shouldn’t have to pay any expenses for their education if the treaties were really upheld by federal court. But the court will probably want to put a deadline on it because who wants to pay “as long as the grass grows, the water flows,”?
