In July 1996, ancient remains of a man were found near Kennewick, Washington. He has been called Kennewick Man or the "Ancient One" (by Native Americans). CTUIR joined with the Nez Perce Tribe, Confederated Tribes and Bands of the Yakama Nation, Confederated Tribes of the Colville Reservation and the Wanapum Band in seeking to have the remains reburied as required by traditional tribal law and according to the 1990 federal Native American Graves Protection and Repatriation Act (NAGPRA). The remains were estimated to be 9,000 years old and scientists wanted to study them. A series of court cases followed; in 2004 the 9th Circuit Court of Appeals ruled to allow more studies before releasing the remains to the tribes. CTUIR decided not to pursue any more legal action but is seeking to strengthen NAGPRA.
