New Jersey Appellate Court Considers Warrantless Blood Draw and Credibility Questions in DWI Case
A defendant in a New Jersey driving while intoxicated (DWI) case can appeal a negative outcome, but appellate courts are limited in their authority to review some lower court actions. A recent decision by the New Jersey Superior Court, Appellate Division illustrates two important issues in a DWI defense. The defendant in State v. Hernandez challenged the evidence that she was intoxicated, arguing that police had her blood drawn without a warrant in violation of her Fourth Amendment rights. She also, at one point in the appeal, challenged the trial court’s findings regarding the credibility of her testimony as compared to several police officers’ testimony. Limitations on the appellate court’s ability to review factual findings, as well as the timeliness of the defendant’s objections, largely determined the court’s ruling.
The “exigent circumstances” exception to the Fourth Amendment’s warrant requirement allows police to conduct a warrantless search if they reasonably believe that there is a substantial risk of the loss or destruction of evidence. Police have used this exception to justify drawing blood from a DWI suspect without a warrant. In 2013, however, the U.S. Supreme Court ruled in Missouri v. McNeely that the human body’s natural process of metabolizing alcohol is not an “exigent circumstance” justifying a warrantless blood draw. Police can still establish legitimate justifications for warrantless blood draws, but McNeely set a much higher standard than before.
