Post-conviction relief (PCR) allows a defendant to challenge a conviction even after the time period to file an appeal has passed, provided they can assert certain grounds for doing so. Under New Jersey law, a PCR petition must allege a significant violation of a defendant’s legal or constitutional rights, rather than just an error by a lower court. If a defendant can establish a violation of their rights, the court may order a new trial, modify the sentence, or, if the defendant is incarcerated, order their release. A recent decision by the New Jersey Appellate Division, State v. Cooper, considered a claim for post-conviction review in a driving while intoxicated (DWI) case, based, in part, on a claim of insufficient evidence. Specifically, the defendant’s blood alcohol content (BAC) test results were below the legal limit, and the defendant argued that the remaining evidence did not support a finding of guilt.
New Jersey municipal courts have original jurisdiction over DWI cases, so that is where defendants must file petitions for PCR. Rule 7:10-2 of the New Jersey Rules of Court governs PCR procedures. It identifies several possible grounds for PCR, including any ground that could be raised to challenge a conviction “by habeas corpus or any other common law or statutory remedy.” This catch-all category covers a wide area of law. In Cooper, the defendant challenged the sufficiency of the evidence but did so by alleging that his counsel at trial was ineffective.
Prosecutors can offer evidence that a defendant operated a vehicle while under the influence of drugs or alcohol in several ways. State law defines DWI to include driving with a BAC of 0.08 percent or higher, but the state can also use testimony by police officers who witnessed the defendant’s behavior during and after their arrest, and who have training in identifying signs of alcohol intoxication. Some New Jersey police departments also employ officers trained in recognizing the physical indicators of drug use. The reliability of such testimony, especially with regard to drugs, is often contested at trial.
