In New Jersey, the path depends first on what kind of offense is charged. A crime prosecuted in Superior Court generally requires a grand-jury indictment, unless the defendant knowingly waives that right and proceeds on an accusation. Municipal Court matters follow a different constitutional and procedural track.
The Six-Month Line Is the Key
New Jersey law draws the basic constitutional line by looking at the maximum jail or prison term the Legislature has authorized for the offense. N.J.S.A. 2C:1-4(a)(1) provides that an offense for which imprisonment in excess of six months is authorized is a “crime” within the meaning of the New Jersey Constitution. Crimes are then graded as first, second, third, or fourth degree.
That makes the 180-day line important. A disorderly persons offense carries no more than six months of incarceration, and a petty disorderly persons offense carries no more than 30 days. By contrast, even the lowest degree crime, a fourth-degree crime, authorizes up to 18 months of imprisonment. Third-, second-, and first-degree crimes carry still greater exposure.
Why That Triggers the Grand-Jury Right
Article I, paragraph 8 of the New Jersey Constitution provides that no person may be held to answer for a criminal offense without a grand-jury presentment or indictment, subject to the Constitution’s limited exceptions. Because N.J.S.A. 2C:1-4 defines an offense carrying more than six months of authorized imprisonment as a constitutional “crime,” an indictable degree crime ordinarily must pass through a grand jury before the State can prosecute it to judgment in Superior Court.
The defendant may knowingly waive indictment and proceed on an accusation under Rule 3:7-2, but absent a valid waiver the indictment requirement is a constitutional protection. In New Jersey state prosecutions, that protection comes from the New Jersey Constitution, not from the federal Fifth Amendment’s Grand Jury Clause.
Why Disorderly Persons Cases Do Not Require Indictment
N.J.S.A. 2C:1-4(b) places disorderly persons and petty disorderly persons offenses on the other side of that line. It expressly calls them “petty offenses,” says they are not crimes within the meaning of the New Jersey Constitution, and provides that there is no right to grand-jury indictment or trial by jury for those offenses. A disorderly persons offense is punishable by no more than six months; a petty disorderly persons offense by no more than 30 days.
Those matters are ordinarily tried in Municipal Court, along with most motor-vehicle and traffic offenses, ordinance violations, and other matters within Municipal Court jurisdiction. There is no grand-jury stage because the charge is not a constitutional “crime” requiring indictment.
Why More Than Six Months Also Matters to the Jury Right
The jury-trial right reaches the same practical dividing line from a different constitutional direction. Article I, paragraphs 9 and 10 of the New Jersey Constitution protect trial by jury in criminal prosecutions, and the Sixth Amendment, applied to the States through the Fourteenth Amendment, requires a jury for a “serious” criminal offense.
The United States Supreme Court has adopted a bright-line rule for incarceration: an offense authorizing more than six months of imprisonment cannot be treated as a petty offense for jury-trial purposes. The New Jersey Supreme Court applied that rule in State v. Denelsbeck, 225 N.J. 103 (2016). When the authorized term is six months or less, the offense is presumed petty, although unusually severe additional statutory penalties can be considered in deciding whether that presumption has been overcome.
That is why a fourth-degree crime, with exposure up to 18 months, carries the constitutional protections associated with a criminal prosecution, while an ordinary disorderly persons offense capped at six months does not carry a jury or grand-jury right. DWI provides a familiar Municipal Court example: even a 180-day maximum term has been held insufficient, without more, to create a jury-trial right because DWI remains a motor-vehicle offense and the total statutory scheme did not make it constitutionally “serious.”
If the Case Is Indictable: What the Grand Jury Does
The grand jury decides whether the State has presented enough evidence for an indictable charge to move forward. It does not decide whether the defendant is guilty beyond a reasonable doubt.
The New Jersey Constitution protects the right to grand-jury indictment for criminal offenses within its scope. Court Rules 3:6 and 3:7 govern grand-jury procedure and the form and return of indictments.
The Proceeding Is Not a Trial
Grand-jury practice is one-sided by design. The prosecutor presents evidence to the grand jurors. The defendant and defense attorney ordinarily are not present to cross-examine witnesses or present the defense case. The Rules of Evidence also do not operate in the same way they do at a criminal trial.
That is why a person should not read too much into the fact that an indictment was returned. A grand jury may indict based on evidence that later becomes subject to suppression, impeachment, exclusion, or a competing factual explanation at trial.
How Many Grand Jurors Have to Agree?
A grand jury does not have to be unanimous. Rule 3:6-8 provides that an indictment may be found only if 12 or more grand jurors concur.
People sometimes describe that as a majority vote because a New Jersey grand jury may be organized with up to 23 members. But “simple majority” is not the precise legal rule. The governing rule is a fixed requirement of at least 12 concurring grand jurors. If fewer than 23 members are participating, the State still needs 12 votes.
How Much Evidence Is Needed?
The State’s burden before the grand jury is far lower than its burden at trial. The presentation must support a prima facie basis for the charge. In practical terms, the State must present evidence from which the grand jury can reasonably find probable cause to believe the offense was committed and the accused committed it.
State v. Hogan, 144 N.J. 216 (1996), is a leading New Jersey case on grand-jury practice. It explains both the limited nature of the proceeding and the prosecutor’s responsibility not to mislead the grand jury.
Must the Prosecutor Present Evidence That Helps the Defense?
Not every piece of favorable evidence must be presented to the grand jury. Hogan imposed a limited duty: the prosecutor must present evidence that is both clearly exculpatory and directly negates guilt.
The Supreme Court later emphasized the narrowness of that rule in State v. Hyppolite, 236 N.J. 154 (2018). Evidence that merely creates a credibility dispute or supports an alternative interpretation is not automatically evidence the prosecutor must present to the grand jury.
Can an Indictment Be Challenged?
Yes, but dismissal of an indictment is not routine. A defense motion can challenge an indictment that is legally defective, unsupported by a prima facie case, based on materially misleading instructions, or affected by serious grand-jury irregularity. Courts generally give indictments substantial deference because the grand jury is a charging body, not the final factfinder.
A successful motion may result in dismissal of some or all counts. Depending on the reason for dismissal, the State may sometimes be permitted to present the matter again to a grand jury.
What Happens After Indictment?
The indictment becomes the formal charging document in Superior Court. The case then moves into post-indictment proceedings that include arraignment, completion and review of discovery, motion practice, plea discussions, and trial preparation.
At this point, the defense can compare the actual indictment with the discovery and ask a much more focused question: can the State prove every element of every count it chose to indict?
