Jury Duty and the Jury System in New Jersey
New Jersey's jury system forms a foundational component of both civil and criminal procedure in the state, ensuring that fact-finding in contested cases is conducted by a cross-section of the community rather than by judicial officers alone. Jury service is a civic obligation imposed by state law, backed by the New Jersey Judiciary's administrative framework. This reference describes the structure of jury duty, the selection process, juror qualifications and exemptions, and the decision-making standards that govern jury verdicts across different case types.
Definition and scope
Jury duty in New Jersey is the compulsory service of qualified residents as fact-finders in Superior Court proceedings. The constitutional basis appears in Article I, Paragraph 9 of the New Jersey Constitution, which preserves the right to trial by jury in criminal cases, and Article I, Paragraph 8, which addresses the right in civil matters. The New Jersey Superior Court, the trial-level court of general jurisdiction, is the primary venue where jury trials occur.
New Jersey uses two distinct jury classifications:
- Grand juries — Panels convened to determine whether sufficient probable cause exists to indict a defendant in a criminal matter. A grand jury in New Jersey consists of 23 citizens; at least 12 must concur for an indictment to issue (New Jersey Court Rules, R. 3:6).
- Petit juries — Trial juries that hear evidence and return verdicts. Criminal cases require 12 jurors; civil cases require 6 jurors under N.J. Court Rule R. 1:8-2.
The New Jersey Judiciary publishes juror qualification standards under the Juror Selection and Service Act, N.J.S.A. 2B:20-1 et seq. Qualification requires that a prospective juror be a United States citizen, a New Jersey resident, at least 18 years of age, and sufficiently proficient in English to follow proceedings.
Scope boundary: This page addresses jury service within New Jersey state courts. Federal courts operating in New Jersey — including the United States District Court for the District of New Jersey — operate under the federal Jury Selection and Service Act of 1968 (28 U.S.C. §§ 1861–1878) and are not covered here. Municipal courts in New Jersey do not conduct jury trials; those proceedings fall outside this reference.

How it works
Juror selection in New Jersey follows a multi-phase process administered by the Assignment Judge in each vicinage (county-level judicial unit) under the supervision of the New Jersey Supreme Court.
Phase 1 — Source list compilation. Juror source lists are drawn from voter registration rolls, motor vehicle records, and state tax filings. The combination of these sources is intended to produce a fair cross-section of the community, consistent with the requirement under N.J.S.A. 2B:20-4.
Phase 2 — Summons. Randomly selected individuals receive a jury summons by mail. Failure to respond can result in a court order compelling appearance; willful noncompliance may constitute contempt of court under New Jersey law.
Phase 3 — Qualification questionnaire. Summoned individuals complete a qualification form. Those who are disqualified (non-citizens, convicted felons whose civil rights have not been restored, or those with a disqualifying mental or physical condition) are excused at this stage.
Phase 4 — Voir dire. Prospective jurors assembled at the courthouse undergo voir dire — a formal questioning process conducted by the judge and attorneys to identify potential bias. Each side in a criminal case receives a set number of peremptory challenges (20 per side in first-degree cases, under R. 1:8-3), which allow dismissal of a juror without stated cause. Unlimited challenges for cause are also available.
Phase 5 — Empanelment and trial. Once a jury is seated, jurors hear opening statements, witness testimony, documentary evidence, and closing arguments before deliberating in private. In criminal cases, a verdict must be unanimous (N.J.S.A. 2B:23-14). In civil cases, 5 of 6 jurors must agree.
The full regulatory framework governing juror conduct, compensation, and deliberation is maintained by the New Jersey Judiciary.
Common scenarios
Criminal felony trial. In indictable offenses (equivalent to felonies in other states), a 12-person jury is required. The prosecution must prove guilt beyond a reasonable doubt, the highest evidentiary standard in New Jersey law. Jurors in a first-degree murder case, for instance, face deliberations that may extend across multiple days. For broader context on how sentencing follows conviction, see New Jersey criminal sentencing guidelines.
Civil Superior Court trial. A 6-person jury resolves disputed facts in civil litigation — personal injury, contract disputes, and similar matters covered under New Jersey tort law or contract law. The standard of proof is preponderance of the evidence (more likely than not), a materially lower threshold than in criminal proceedings.
Hardship and deferral. A juror with documented financial, medical, or caregiving hardship may request a deferral or excuse. The Assignment Judge or jury manager evaluates such requests on a case-by-case basis. Self-employed individuals, caregivers with no available substitute, and active-duty military personnel are among those who frequently invoke hardship provisions.
Grand jury service. Grand juries in New Jersey typically sit for a term of several months, hearing multiple matters. Grand jurors operate under strict secrecy requirements (R. 3:6-7) and may not disclose deliberations.
Decision boundaries
Understanding the distinctions between jury types and standards governs how outcomes are reached:
| Factor | Criminal petit jury | Civil petit jury | Grand jury |
|---|---|---|---|
| Size | 12 jurors | 6 jurors | 23 members |
| Verdict threshold | Unanimous (12/12) | 5 of 6 agree | 12 concur for indictment |
| Standard of proof | Beyond reasonable doubt | Preponderance of evidence | Probable cause |
| Presiding authority | Superior Court judge | Superior Court judge | Assignment Judge |
Jurors who observe misconduct during deliberations — such as outside research or juror-to-juror intimidation — are expected to report it to the trial judge immediately. Post-verdict juror misconduct that affected deliberations can form the basis of a motion for a new trial, though courts apply a high threshold before disturbing a verdict (see State v. Harvey and related New Jersey Supreme Court precedent).
Jurors are compensated at a rate set by the New Jersey Legislature under N.J.S.A. 2B:20-10. The regulatory context for the New Jersey legal system situates jury service within the broader constitutional and statutory architecture of state law.
Employers in New Jersey are prohibited from penalizing employees for jury service under N.J.S.A. 2B:20-17, which classifies such retaliation as a disorderly persons offense. This protection applies regardless of the length of service.
