State of Arizona, Appellee v. Patrick McLeod Nissley, Appellant

Summary

The court held that Arizona's medical blood draw exception requires the State to prove probable cause, exigent circumstances, a medically motivated blood draw, and compliance with the suspect's right to direct medical treatment. That right is satisfied by express or implied consent, or when medical personnel treat a suspect who is incapable of providing consent. The court vacated the court of appeals' decision and remanded for fact-finding on whether Nissley was capable of directing his treatment and whether the treatment violated that right.
