State of Iowa v. Colby Davis Laub

Summary

The court held that Iowa's implied-consent procedure is not the exclusive method for obtaining chemical evidence in an OWI investigation. An officer may instead obtain a constitutionally valid search warrant for a bodily specimen, and Iowa's general warrant statute authorizes warrants for collecting evidentiary bodily specimens. The court also rejected equal-protection and due-process challenges to the officer's choice to obtain a warrant rather than invoke implied consent.
