A defendant's tribal enrollment certificate isn't enough to prove he is an "Indian" for purposes of federal law, the 9th Circuit Court of Appeals ruled on Thursday.

Damien Zepeda possesses a "Certificate of Enrollment" from the Gila River Indian Community, a federally recognized tribe in Arizona. It states that he has 1/4 "Pima" and 1/2 "Tohono O’odham" blood.

However, federal prosecutors did not prove that Zepeda's Indian blood comes from a federally-recognized tribe, the court determined by a 2-1 vote. Neither "Pima" nor "Tohono O’Odham" appear on the list of federally recognized tribes, the decision stated.

"The government introduced no evidence that any of these Indian groups are a federally recognized tribe," Judge Richard A. Paez wrote for the majority.

As a result, the court reversed Zepeda's conviction by a jury. He had been found guilty of conspiracy to commit assault, assault with a deadly weapon and use of a firearm during a crime of violence in connection with a shooting incident on the Ak-Chin Indian Community that left a victim severely injured.

Judge Paul J. Watford dissented. He said any "rational" jury could have inferred that Zepeda's "Tohono O’Odham" blood in fact comes from the Tohono O'odham Nation.
