But they say CU investigators guilty of academic misconductChurchill claims the blood quantum standard is similar to codes adopted by the Nazis to define Jews. Such a code is also controversial, because tribes claim they--not the federal government--have the right to determine their membership.

Churchill says the blood quantum standard is in an 1887 law that imposed private ownership of land on Indians in place of the traditional communal ownership by the tribe.

But legal scholars have said the 1887 law, called the General Allotment Act, contains no reference to blood quantum. The CU investigative committee upheld that view.
