The United States Supreme Court heard oral arguments this morning in three cases involving the chemical testing of impaired drivers. The question before the court in each case is whether, in the absence of a warrant, a state may make it a crime for a person to refuse to take a chemical test to detect the presence of alcohol in the person’s blood. I’m eager to hear what the high court has to say about this issue and to learn whether it will impact North Carolina’s implied consent laws, which, like the laws in every other state, do provide for warrantless chemical testing, but which do not criminalize refusal to be tested. But we don’t have to wait for the Supreme Court’s opinion to see how our state’s implied consent laws are evolving in a post-Missouri v. McNeely world. The North Carolina Court of Appeals decided a significant case yesterday, ruling in State v. Romano, __ N.C. App. ___ (2016), that the warrantless withdrawal of blood from an unconscious impaired driving suspect violated the Fourth Amendment, notwithstanding a state statute that permits such actions.
