New Jersey Criminal Procedure: From Arrest to Sentencing

New Jersey criminal law is governed primarily by the New Jersey Code of Criminal Justice (Title 2C of the New Jersey Statutes), which was enacted in 1979 and is modeled on the Model Penal Code. The Code classifies offenses into crimes (indictable offenses, equivalent to felonies in other states) and disorderly persons offenses (equivalent to misdemeanors). Crimes are further divided into four degrees:

A New Jersey arrest may occur with or without a warrant. A warrantless arrest is lawful when a police officer has probable cause to believe that a crime has been committed and that the person arrested committed it. Following arrest, the defendant must be brought before a judge for an initial appearance without unnecessary delay — typically within 12 hours for indictable offenses.

At the initial appearance, the judge informs the defendant of the charges, advises them of their rights (including the right to counsel), and makes a bail determination. Under New Jersey's bail reform law (effective 2017), the state has largely eliminated cash bail in favor of a risk-based pretrial detention system. A Pretrial Services officer assesses the defendant using a validated risk instrument, and the judge may release the defendant on conditions, detain them pending a detention hearing, or release them without conditions.

For indictable offenses (crimes of the first through fourth degree), the New Jersey Constitution requires that charges be presented to a grand jury before the defendant can be tried. A grand jury consists of 23 citizens, and a finding of probable cause requires the concurrence of at least 12. Grand jury proceedings are secret — the defendant has no right to be present or to present evidence.

If the grand jury returns a true bill, the defendant is formally indicted and the case proceeds in the Superior Court, Law Division, Criminal Part. If the grand jury returns a no bill, the charges are dismissed (though the prosecutor may re-present to a new grand jury). Disorderly persons offenses are not indictable and are handled entirely in the Municipal Court without grand jury involvement.

After indictment, the defendant is arraigned — formally advised of the indictment and asked to enter a plea. Most defendants plead not guilty at arraignment to preserve their options. The pre-trial period involves extensive discovery (exchange of evidence), and defendants may file motions to suppress evidence obtained in violation of the Fourth Amendment, dismiss the indictment, or change venue.

New Jersey's discovery rules under R. 3:13-3 are broad: the State must disclose all statements of the defendant, co-defendants, and witnesses; the results of all tests and examinations; all prior criminal records; and all exculpatory evidence (Brady material). Failure to disclose Brady material can result in dismissal of charges.

The vast majority of New Jersey criminal cases — approximately 95% — are resolved through plea bargaining rather than trial. A plea agreement typically involves the defendant pleading guilty to a reduced charge or to the original charge in exchange for a sentencing recommendation from the prosecutor. The judge is not bound by the prosecutor's recommendation but must accept or reject the plea agreement in its entirety.

Before accepting a guilty plea, the court must conduct a thorough colloquy to ensure the plea is knowing, voluntary, and intelligent, and that there is a factual basis for the plea. Defendants who plead guilty waive their right to trial, the right to confront witnesses, and the privilege against self-incrimination.

Defendants charged with indictable offenses have the right to a jury trial. A New Jersey criminal jury consists of 12 jurors, and the verdict must be unanimous. The prosecution bears the burden of proving every element of the offense beyond a reasonable doubt — the highest standard of proof in the legal system. The defendant has no obligation to testify or present any evidence.

Other key trial rights include the right to confront and cross-examine witnesses (Confrontation Clause), the right to compulsory process to obtain witnesses in the defendant's favor, and the right to effective assistance of counsel. A defendant who cannot afford an attorney is entitled to a public defender.

New Jersey sentencing is governed by N.J.S.A. 2C:44-1, which requires the court to weigh aggravating and mitigating factors. Aggravating factors include the nature and circumstances of the offense, the defendant's prior criminal record, and the risk of re-offense. Mitigating factors include the absence of a prior record, the defendant's role as a minor participant, and substantial grounds tending to excuse the conduct.

New Jersey has several mandatory minimum sentencing provisions. The No Early Release Act (NERA) (N.J.S.A. 2C:43-7.2) requires defendants convicted of certain violent crimes to serve 85% of their sentence before becoming eligible for parole. The Graves Act (N.J.S.A. 2C:43-6) imposes mandatory minimum sentences for certain firearms offenses.
