The nature of the federal government's obligation to the Indian tribes goes beyond just honoring treaties and laws. Its more in the nature of a guardianship/trustee relationship: http://www.nihb.org/tribal_resources/indian_health_101.php. The government is not obligated to believe the Indian version of facts, but federal agencies responsible for Indian affairs are not and cannot be neutral parties when others make claims that affect Indian interests.
