Reviewed by William A. Proetta, Esq. · Updated October 2026

Possessing a firearm with the purpose of using it unlawfully against another person or their property is a second-degree crime under N.J.S.A. 2C:39-4(a)(1), with a range of five to ten years and a mandatory Graves Act parole bar. Lesser versions cover knives and other weapons (third degree) and imitation firearms (fourth degree). In Jersey City, these charges are prosecuted in the Hudson County Superior Court at the Frank J. Guarini Justice Complex near Journal Square.

The Four Elements of an Unlawful Purpose Charge

This statute is about intent, not just possession. To convict, the State must prove four things beyond a reasonable doubt:

1. The object was a weapon (or, under subsection (a), a firearm).
2. You possessed it.
3. Your purpose in possessing it was to use it against the person or property of another.
4. That purpose was unlawful.

The purpose must exist while you have the weapon. Jurors are asked to infer it from the surrounding facts, such as statements made, how the weapon was displayed and what happened afterward. A person can lawfully own a firearm and still be charged under this statute, and a person can possess a gun illegally without having any unlawful purpose at all. Those are separate questions, and separating them is often the core of the defense.

Firearms, Community Guns, Other Weapons and Imitations

Subsection (a)(1) is the main firearm offense. It is second degree and is listed in the Graves Act.

Subsection (a)(2), known as the community gun provision, is also second degree, and it carries its own parole bar of the greater of one-half of the sentence or three years.

Subsection (d) covers knives, bats, clubs and any other weapon possessed with an unlawful purpose. It is third degree, with a range of three to five years and a fine of up to $15,000, and it is not a Graves offense.

Subsection (e) applies to an imitation firearm possessed under circumstances that would lead an observer to believe it was meant for an unlawful purpose. It is fourth degree, with up to 18 months and a fine of up to $10,000.

Sentencing and the Diaz Merger Rule

A conviction under (a)(1) carries five to ten years, a fine of up to $150,000 and a Graves Act parole bar equal to the greater of one-half of the term or 42 months. Because this charge is so often paired with a substantive crime, merger is a central sentencing question. Under State v. Diaz, 144 N.J. 628 (1996), a conviction for possessing a weapon for an unlawful purpose generally merges into the substantive offense when the only unlawful purpose shown was to commit that offense. A separate sentence is permitted only when the record shows a broader unlawful purpose than the crime itself. Merger can remove a count, and with it a separate Graves term, from the final judgment.

Graves Waiver, Plea Strategy and PTI

In many cases the realistic goal is to eliminate the unlawful purpose count or to restructure the plea. Resolving the case on a non-Graves count, or with a 2C:43-6.2 waiver, can change the parole math; a plea to a (b)(1) handgun count carries the same Graves bar. Where a firearm count remains, a prosecutor’s motion under N.J.S.A. 2C:43-6.2 can reduce the parole bar to one year or allow probation; see our Hudson County weapons offenses guide for how that motion works. Because an (a)(1) charge carries a mandatory parole bar, PTI requires the prosecutor’s consent before an application can be considered. A subsection (d) knife case, by contrast, is not subject to the Graves Act, which leaves more room for a probationary or diversionary outcome.

Unlawful Purpose Weapons Charges in Jersey City

In Jersey City, these charges frequently accompany an assault, robbery or threat allegation, for example after a street confrontation where a witness says someone displayed a gun or a knife. A case can also begin when officers find a weapon after a 911 call describing a dispute, and the charging decision is based on what was said rather than what was done. Similar cases arise in Bayonne, Union City and Kearny. The count is reviewed by the prosecutor’s office and, if indicted, tried in Superior Court near Journal Square. See our Jersey City gun charges page and our court guides for Jersey City, Hoboken, Kearny, Union City and Bayonne.

Arrest and Pretrial Release

When an unlawful purpose count is filed with a violent offense, the prosecutor is likely to argue for detention based on danger to the community. The defense response focuses on the actual evidence of purpose, which may be thinner than the complaint suggests, and on release conditions such as no contact with the alleged victim. See our pretrial release and detention guide and our page on Central Judicial Processing in Hudson County.

Immigration Consequences

The immigration analysis for this charge depends on the weapon and the accompanying offense. A firearm count can create deportability as a firearms offense, while a conviction tied to a violent crime raises separate concerns, so the plea should be structured with both in mind. We review the immigration side before any plea; see our immigration consequences and immigration-safe plea strategy pages.

Defenses to Possession for an Unlawful Purpose

• No unlawful purpose. Carrying a weapon, even illegally, is not the same as intending to use it unlawfully against someone. The State must prove the purpose.
• Protective purpose. When the evidence shows the weapon was held to protect yourself rather than to harm another person, the unlawful purpose element may not be met.
• Witness credibility. Many of these cases depend on one witness’s account of a threat or display, which can be tested on cross-examination.
• Merger. Even after a conviction, Diaz can eliminate the separate sentence.
• Not a real firearm. If the object was an imitation, the charge belongs under subsection (e) at most, not (a).
