The New Jersey Supreme Court has agreed to decide whether a U.S. Supreme Court ruling on the necessity of warrants for blood draws in drunken-driving cases only reaches future matters.

The court granted a petition for certification in a case hinging on the retroactivity of Missouri v. McNeely, 133 S.Ct. 152 (2013), where the justices said a blood draw amounts to a search and dissipation of alcohol in the bloodstream by itself does not qualify as an exigent circumstance to skirt the warrant requirement.
