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 operating-while-intoxicated investigation. A peace officer may instead obtain and execute a search warrant for a bodily specimen, and the governing search-warrant statutes authorize seizure of such specimens. The court also rejected Laub's equal-protection and substantive- and procedural-due-process challenges because the statutory scheme makes no suspect classification, the officer's discretionary investigative choice was not arbitrary discrimination, and a warrant provided constitutionally sufficient process.
