A felony in New York generally must be presented to a grand jury for indictment, or waived by superior court information. The grand jury is a one-sided proceeding: the prosecutor presents evidence, gives the legal instructions, and asks for an indictment. There is no judge in the room. There is no defense attorney in the room unless the target chooses to testify.
Under CPL § 190.50, a person who has been arraigned on a felony complaint has the right to testify before the grand jury. The right must be invoked in writing. If the prosecution proceeds without giving the accused notice, the resulting indictment can be dismissed under CPL § 210.35(4). The procedure is technical, the deadlines are short, and the choice to testify is one of the most consequential decisions in a felony case.
The conventional answer is no. The grand jury's standard of proof is low (legally sufficient evidence and reasonable cause), the cross-examination is the prosecutor's, the recorded transcript can be used to impeach you for the rest of the case, and the rate at which testimony actually produces a no-true-bill is low. But there are cases where it makes sense — affirmative-defense cases, mistaken-identity cases, and cases where a target letter has already telegraphed the issues. The decision should be made with counsel after seeing as much of the prosecution evidence as possible.
The accused may also call witnesses before the grand jury. The grand jury, with the prosecutor's permission, decides whether to hear them. Defense witnesses are rare but occasionally pivotal.
A New York grand jury is a body of citizens drawn from the same pool as petit jurors. Under CPL § 190.05, it consists of not fewer than sixteen and not more than twenty-three persons. Sixteen constitute a quorum, and at least twelve must vote affirmatively for the grand jury to act — whether the act is voting an indictment, filing a prosecutor's information, or directing the filing of a charge for a misdemeanor.
The grand jury sits in secret. Only the District Attorney, the witnesses, the stenographer, the grand jurors themselves, and an interpreter or counsel for a testifying witness may be present. The judge is not in the room. The defense lawyer is not in the room unless the target is testifying — and even then, counsel may not address the grand jurors or object.
Only the District Attorney may present evidence to a grand jury. The DA selects the witnesses, frames the questions, and provides the legal instructions. The evidentiary rules are relaxed — hearsay is broadly admissible under CPL § 190.30 — but the prosecutor still has obligations to instruct accurately on the law and to disclose exculpatory matter that would materially influence the grand jury's decision (People v. Lancaster; People v. Pelchat).
The grand jury's standard is not beyond reasonable doubt. It is legally sufficient evidence and reasonable cause to believe that the defendant committed the offense charged (CPL § 190.65). That is a low bar, and it is the reason most presentations end in true bills.
A witness who testifies before a New York grand jury receives transactional immunity by operation of law under CPL § 190.40 — the broadest form of immunity in American practice. The witness cannot be prosecuted for any offense arising from the transaction about which he testified. Targets and certain other witnesses may sign a waiver of immunity under CPL § 190.45, and the waiver must be signed in open court and acknowledged on the record. The waiver covers only the proceeding in which it is given.
Grand-jury proceedings are sealed under CPL § 190.25(4). Disclosure of grand-jury testimony or evidence requires a court order on a showing of "compelling and particularized need." That secrecy cuts both ways — it protects the integrity of the proceeding and the privacy of witnesses, but it also makes it difficult for the defense to evaluate weaknesses in the case before indictment.
The conventional answer is no. The grand jury's standard of proof is low (legally sufficient evidence and reasonable cause), the cross-examination is the prosecutor's, the recorded transcript can be used to impeach you for the rest of the case, and the rate at which testimony actually produces a no-true-bill is low. But there are cases where it makes sense — affirmative-defense cases (justification under PL Article 35, duress, mistake of fact), mistaken-identity cases, and cases where a target letter has already telegraphed the issues. The decision should be made with counsel after seeing as much of the prosecution evidence as possible.
Counsel can be in the room during the target's testimony under CPL § 190.52, but the role is limited — advising the client, not objecting or questioning. The waiver of immunity must be carefully scoped, and prep is everything. A transcript that locks in inconsistent or impeachable testimony is far worse than no testimony at all.
Once an indictment is filed, the defense has a narrow window under CPL § 255.20 to move to dismiss. CPL § 210.20 authorizes dismissal on multiple grounds:
The most common and most productive challenge is the motion to inspect the grand-jury minutes under CPL § 210.30 and to dismiss for legal insufficiency. The judge reviews the transcript in camera, evaluates the prosecutor's legal instructions, and either dismisses, reduces, or sustains the indictment.
Federal grand juries operate under Federal Rule of Criminal Procedure 6. They share the broad structure of New York grand juries — secrecy, prosecutor presentation, low evidentiary threshold — but the practice differs in several important respects. There is no statutory right to testify before a federal grand jury; appearance is by subpoena or by invitation. Federal immunity, when granted, is "use and derivative use" under 18 U.S.C. § 6002 — narrower than New York's transactional immunity. And the federal grand jury's investigative reach — document and testimonial subpoenas, often deployed long before charges are visible — far outstrips state practice. Where a parallel federal investigation is in motion, the federal grand jury usually moves first.
A defendant facing felony charges may waive grand-jury presentation entirely under CPL § 195.10 and proceed by Superior Court Information (SCI). The waiver is in writing, in open court, with counsel, and after the court is satisfied that the defendant understands the right being waived. SCI dispositions usually accompany a pre-negotiated plea deal — the client trades the grand-jury process for a known sentence. The waiver is not available where the indictment would be for a Class A felony or where the People object.
In white-collar and long-investigation cases, the first sign of a grand-jury presentation may be a "target letter" from the District Attorney or U.S. Attorney advising the recipient that he is the subject of an investigation and inviting (or summoning) testimony. The letter is itself a strategic opportunity — it permits a written pre-indictment submission ("declination memo"), proffer discussions, and in some cases a pre-charge resolution. The decision whether to engage, when to engage, and on what terms must be made with counsel before any contact with the prosecutor's office.
After indictment, the case is arraigned in Supreme Court (or County Court outside NYC). Bail is reviewed under CPL Article 510. The discovery clock under CPL Article 245 continues to run, and the 30.30 felony clock — six months from commencement — is recalibrated against time already charged on the felony complaint.
The defense work then shifts to:
