New York Grand Jury Process: How Indictments Work

The grand jury occupies a constitutionally protected position in New York's felony prosecution framework, serving as the primary mechanism by which the state formally accuses individuals of serious crimes. Governed by Article 190 of the New York Criminal Procedure Law (CPL), the grand jury process determines whether sufficient evidence exists to compel a defendant to stand trial. Understanding this process is essential for legal professionals, journalists, and researchers tracking criminal proceedings across the state's unified court structure.

Definition and scope

A grand jury in New York is a body of 23 citizens empaneled under New York Criminal Procedure Law § 190.05 to examine evidence in criminal matters and decide whether a formal charge — an indictment — should issue. The institution derives its authority from Article I, Section 6 of the New York State Constitution, which preserves the right to grand jury review for felony offenses prosecuted in Supreme Court or County Court.

Grand juries in New York operate at the county level, convened by the Supreme Court or County Court of the relevant jurisdiction. They function independently of the trial jury (petit jury) and are not tasked with determining guilt. Their sole mandate is to assess whether probable cause supports charging a specific individual with a specific crime.

This process applies exclusively to felony-level charges within the New York State court system. Misdemeanor prosecutions, which proceed by information or complaint rather than indictment, fall outside grand jury jurisdiction. For a broader orientation to criminal charging procedures, see the New York Criminal Procedure Overview.

Scope limitations: This page addresses grand jury procedure under New York State law as codified in CPL Article 190. Federal grand jury proceedings — governed by Rule 6 of the Federal Rules of Criminal Procedure and convened in the Southern District, Eastern District, Northern District, or Western District of New York — operate under a separate legal framework and are not covered here. For federal court jurisdiction in New York, see Federal Courts in New York.

How it works

The New York grand jury process follows a defined procedural sequence established by CPL Article 190.

  1. Empaneling the grand jury. A grand jury consists of 23 jurors drawn from the same pool used for trial juries. At least 16 must be present to constitute a quorum under CPL § 190.25.

  2. Presentation by the prosecutor. The District Attorney's office presents evidence — witness testimony, documentary exhibits, physical evidence — directly to the grand jury. Defense counsel is generally excluded from this proceeding, though a defendant may request the opportunity to testify under CPL § 190.50.

  3. Legal instructions from the court. A judge instructs the grand jury on the legal standards applicable to the charges under consideration. These instructions are recorded and form part of the grand jury minutes.

  4. Deliberation in secrecy. Grand jury deliberations are strictly confidential under CPL § 190.25(4). No unauthorized person may be present during deliberations. Violations of grand jury secrecy can result in criminal contempt charges.

  5. The vote. A minimum of 12 of the 23 grand jurors must vote to indict (CPL § 190.25(1)). This threshold reflects probable cause, a standard substantially lower than the "beyond a reasonable doubt" burden at trial.

  6. Filing the indictment or declining to indict. If 12 or more jurors vote to indict, the grand jury files a true bill. If fewer than 12 vote to indict, the grand jury files a no bill, and the prosecution cannot proceed on that charge by that route without new evidence or a new grand jury presentation.

Witnesses who testify before a grand jury receive immunity protection under certain conditions. Transactional immunity, which bars prosecution for any offense related to the testimony, differs from use immunity, which bars only the use of the testimony itself in a subsequent prosecution. New York's scheme under CPL § 190.40 confers transactional immunity on witnesses compelled to testify.

Common scenarios

Felony arrests requiring grand jury action. When a defendant is arraigned in local criminal court on a felony complaint, the prosecution must present the case to a grand jury within 45 days if the defendant is held in custody, or within a longer period if the defendant is at liberty (CPL § 190.80). Failure to meet this deadline can result in the reduction or dismissal of charges.

Defendant elects to testify. Under CPL § 190.50, a defendant who has been arraigned on a felony complaint has a statutory right to testify before the grand jury if proper written notice is given before the grand jury votes. This is a significant strategic decision, as grand jury testimony can later be used for impeachment at trial.

Sealed indictments. A grand jury indictment may be sealed by court order under CPL § 190.25(4)(a) when disclosure would compromise an ongoing investigation or endanger a witness. Sealed indictments remain inactive until the defendant is taken into custody.

Superseding indictments. A prosecutor may convene a second grand jury to obtain a superseding indictment — one that modifies or expands the charges — even after an initial indictment has been filed. This mechanism is distinct from reindictment after a no bill, which requires a showing of new or additional evidence.

Decision boundaries

The central decision issued by a grand jury — to indict or not to indict — rests on probable cause, defined under New York law as reasonable cause to believe the accused committed the charged offense. This standard is codified at CPL § 70.10(2).

Grand jury vs. preliminary hearing. New York does not conduct preliminary hearings as a substitute for grand jury review in felony cases. This contrasts with federal practice and the practice of states such as California, where a defendant may elect a preliminary hearing in lieu of grand jury indictment. In New York, the grand jury is the constitutionally mandated route for felony prosecution initiated in Supreme Court or County Court.

Grand jury vs. superior court information. Under CPL § 195.10, a defendant who has been held for action of the grand jury may, with the court's approval and the People's consent, waive indictment and be prosecuted by superior court information. This waiver mechanism allows cases to move forward without a full grand jury presentation — but only with the defendant's affirmative, written consent. A defendant cannot be compelled to waive indictment.

Challenging the indictment. A defendant may move to dismiss an indictment under CPL § 210.20 on grounds that include legally insufficient evidence before the grand jury, defective grand jury proceedings, or the prosecutor's failure to instruct the jury on applicable defenses. Courts review grand jury minutes in camera when such motions are filed.

The grand jury's role intersects with bail determinations, arraignment procedures, and subsequent pretrial litigation.
