How a case moves here
Essex County follows New Jersey law on arrests, release, and courts. These rules are the same in every county in the state; the full set covers prosecutors, defense, and jails too.
- Who decides release first
A judge makes the first release decision. A person arrested on a complaint-warrant goes to the county jail, and a Superior Court judge or a municipal judge designated by the Chief Justice decides release at a centralized first appearance. People charged on a complaint-summons are released by police with no conditions.

N.J. Ct. R. 3:4-2(a)(1), as described in NJ Courts, Criminal Division Overview- Money bail
Since January 1, 2017, New Jersey's Criminal Justice Reform Act has made release without money the default. A prosecutor may instead ask a judge to hold a person without bail after a detention hearing.

The governor nominates Superior Court judges and the state Senate confirms them for a first term of seven years. A judge who is reappointed has tenure to age 70. Municipal court judges are lawyers with at least five years of practice, appointed by the town for three-year terms with no tenure.

Read from the statutes and court rules cited, 2026-09-30. Some of this is medium confidence and still being checked. Court rule and statute text came through the Judiciary's Criminal Division Overview (2018) rather than the current rule text; justia.com blocked direct reads of N.J.S.A. 2A:158-1 and 2A:162-16. The municipal public defender statute was not opened. No count of sheriff-run versus department-run jails was confirmed.
