The People of the State of Colorado, Plaintiff-Appellant v. William Paul Simpson, Defendant-Appellee

Summary

The court held that Simpson's decision to drive in Colorado constituted prior consent to a blood test under the state's expressed-consent statute when an officer had probable cause to suspect impaired driving. That statutory consent satisfied the Fourth Amendment consent exception and made it unnecessary to determine whether Simpson's later consent at the hospital was voluntary, so the suppression order was reversed. Justice Eid, joined by Chief Justice Rice and Justice Coats, concurred only in the judgment for the reasons stated in a related opinion.
