Belonging in Native nations, which was historically a matter of kinship, has become increasingly legalistic. More than 80 of the 567 federally recognized tribes, in 17 states, have deployed the practice, typically for political or financial reasons. While tribal leaders assert that disenrollments are meant to correct tribal rolls and protect the integrity of the tribe, empirical data shows they are politically and economically motivated.
Article 9 of the UN Declaration on the Rights of Indigenous Peoples states: "Indigenous peoples and individuals have the right to belong to an indigenous community or nation, in accordance with the traditions and customs of the community or nation concerned. No discrimination of any kind may arise from the exercise of such a right. Article 33 of that UN states that "Indigenous peoples have the right to determine their own identity or membership in accordance with their customs and traditions." Individual and tribal rights clash in the disenrollment context.
In the United States, it is entirely up to the tribes to determine the criteria and procedures that an individual must meet and undergo to be considered for tribal membership.  Most tribes do so pursuant to artificial tribal membership standards meted out by the U.S. Congress pursuant to the Indian Reorganization Act of 1934, most notably blood quantum.
An increasing number of Native American associations urge tribes to reconsider disenrollment, or to at least ensure that any such process comports with fundamental notions of due process at law. The Association of American Indian Physicians has decried disenrollment because it "perpetuates historical trauma", resulting in "health risks", including "suicide, homicide, accidental deaths, domestic violence, child abuse and alcoholism, as well as other social problems". The National Native American Bar Association has declared it "immoral and unethical" for "any lawyer" to help tribes remove people from their rolls without an adequate process to address the rights of the individuals.
