In any court proceeding in which the state seeks to impose penalties on a person for an alleged violation of the law, the defendant has the right to obtain evidence used by the state in the case. The process of obtaining evidence from opposing parties is known as “discovery” in both civil and criminal proceedings. Under New Jersey law, driving while intoxicated (DWI) is considered a traffic offense rather than a criminal offense, but defendants are still entitled to discovery before a case goes to trial. New Jersey courts have held, however, that a defendant’s right to discovery in a DWI case is narrower than in a criminal case. The court reviewed these rights, and the state’s obligations, in February 2016 in State v. Conroy, when it ruled on a defendant’s challenge to the state’s evidence.
New Jersey law enforcement uses a device known as the Alcotest to measure blood alcohol concentration (BAC) in breath samples obtained from DWI suspects. State law requires any law enforcement officer operating an Alcotest device to be certified in accordance with standards established by the New Jersey Attorney General. These standards, which are codified in Title 13, Chapter 51 of the New Jersey Administrative Code (NJAC), require a Breath Test Operator (BTO) to have an “operator’s certificate” that is valid at the time they administer a test to a suspect. The NJAC states that a “replica certificate” with the “facsimile signature of the Superintendent [of the State Police] and the Attorney General” is valid to establish a BTO’s credentials.
The New Jersey Supreme Court’s 2008 decision in State v. Chun established that the state must produce certain documents in any case that relies on breath testing evidence obtained with an Alcotest device. Subsequent decisions from the Appellate Division have identified types of evidence that do not fall under the requirements of Chun. Two decisions, State v. Maricic from 2010 and State v. Carrero from 2012, held that discovery in DWI cases is more limited than in criminal proceedings.
