“ There can be no doubt that to allow the exercise of state jurisdiction here would undermine the authority of the tribal courts over Reservation affairs and hence would infringe on the right of the Indians to govern themselves. It is immaterial that respondent is not an Indian. ”

No departure from the policies which have been applied to other Indians is apparent in the relationship between the United States and the Navajos. On June 1, 1868, a treaty was signed between General William T. Sherman, for the United States, and numerous chiefs and headmen of the 'Navajo nation or tribe of Indians'. ”

This policy contemplates criminal and civil jurisdiction over Indians by any State ready to assume the burdens that go with it as soon as the educational and economic status of the Indians permits the change without disadvantage to them. ”
