DWI Defendant Asserts Necessity Defense in New Jersey Court
The state has the burden of proving a defendant’s guilt beyond a reasonable doubt in New Jersey criminal cases, as well as cases involving motor vehicle offenses like driving while intoxicated (DWI). Some defenses that a defendant can raise shift the burden of proof, requiring the defendant to produce evidence in support of their defense. These are known as affirmative defenses. The defendant’s burden of proof for an affirmative defense is a preponderance of the evidence, which is lower than the state’s burden. The affirmative defense of necessity, or justification, requires proof by a preponderance of the evidence that their commission of the charged offense was necessary, under the circumstances, to prevent an even greater harm. The New Jersey Appellate Division recently considered how this applies in DWI cases in State v. Han.
New Jersey defines the necessity defense in broad, rather unhelpfully technical terms, stating that an act that might constitute a criminal offense could be “justifiable by reason of necessity to the extent permitted by law.” Court rulings have crafted more practical guidelines for the justification defense, but they do not necessarily apply in DWI cases. As the court notes in Han, DWI is a motor vehicle offense, but the statute defining the necessity defense is found in the New Jersey Code of Criminal Justice. Not all protections afforded in criminal cases are available in motor vehicle cases.
