U.S. Supreme Court Grants Review on Issue of Implied Consent

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.
