If you have a criminal DWI case or criminal DWI test refusal case, and/or civil implied consent driver’s license revocation cases pending, you may have heard of the recent U.S. Supreme Court decision in McNeely v. Missouri issued 4-17-13. In McNeely the U.S. Supreme Court held that Warrantless DWI Tests are illegal without consent or “exigency circumstances.” The U.S. Supreme Court said that Missouri could not take a non-consensual blood test from a driver in a standard DWI case (no accident) without either a warrant OR a showing of special circumstances like an emergency stemming from injured persons in a car accident (i.e. “exigent circumstances”).
