The United States Supreme Court granted certiorari a few weeks ago to consider whether a state statute authorizing the withdrawal of blood from an unconscious driver suspected of impaired driving provides an exception to the Fourth Amendment warrant requirement. The case, Mitchell v. Wisconsin, arose in Wisconsin, but the issue may sound familiar to practitioners in North Carolina. Our state supreme court held in State v. Romano, 369 N.C. 678 (2017) (discussed here) that the warrantless withdrawal of blood from an unconscious DWI suspect pursuant to state statute when there was no exigency violated the Fourth Amendment. The Supreme Court of Wisconsin reached a different conclusion in Mitchell. The case provides the United States Supreme Court with an opportunity to tie up the ends it left loose in Birchfield v.

The U.S. Supreme Court waded into the murky waters of implied consent law this term in Birchfield v. North Dakota.

Here’s what we know after Birchfield:
- Warrantless breath testing of impaired driving suspects is permissible under the Fourth Amendment as a search incident to arrest. A person who refuses to submit to such testing may be subjected to sanctions ranging from license revocation to criminal prosecution.
- Warrantless blood testing of impaired driving suspects is not permissible under the Fourth Amendment as a search incident to arrest. Thus, a warrant or a suspect’s consent is required to conduct such testing. A person who refuses to submit to such testing may not be criminally prosecuted for that refusal.
