The Fifth Amendment’s Grand Jury Clause bars the federal government from putting you on trial for a serious crime unless a group of ordinary citizens, sitting as a grand jury, first votes to indict you. The clause reads: “No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury.”1Legal Information Institute. Fifth Amendment It’s a screen, not a trial. Sixteen to twenty-three citizens hear the prosecutor’s evidence in secret and decide whether there is enough to justify dragging you into court. The protection applies only in federal cases, and only to serious ones.
Which Crimes Require a Grand Jury
“Capital, or otherwise infamous crime” effectively covers every federal felony. In Ex parte Wilson (1885), the Supreme Court held that any crime for which the statute authorizes imprisonment at hard labor counts as infamous.2Library of Congress. Ex Parte Wilson, 114 US 417 (1885) What matters is the maximum sentence the law allows, not what a judge actually imposes. Because nearly every federal felony carries the possibility of more than a year in prison, the requirement sweeps in almost all serious federal charges.
Federal misdemeanors and petty offenses fall outside the clause. Prosecutors can bring those through an “information,” a charging document the prosecutor files directly, without ever calling a grand jury.
When the Requirement Applies to You
Federal Cases Only
The Grand Jury Clause binds the federal government. It does not bind the states. The Supreme Court decided that in Hurtado v. California (1884), and the ruling still holds, making the grand jury right one of the few Bill of Rights protections never incorporated against the states through the Fourteenth Amendment.3Justia. Hurtado v California, 110 US 516 (1884)4Constitution Annotated. Amdt5.2.2 Grand Jury Clause Doctrine and Practice
State practice varies. Roughly half the states require grand jury indictments for at least some serious crimes under their own constitutions. The rest let prosecutors initiate felony cases by information, sometimes after a preliminary hearing in front of a judge. If you’re facing a state charge, whether a grand jury sees your case depends entirely on that state’s law.
Military Cases
The amendment itself carves out “cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger.”1Legal Information Institute. Fifth Amendment Service members go through the Uniform Code of Military Justice and court-martial proceedings instead.5Office of the Law Revision Counsel. 10 USC Ch 47 – Uniform Code of Military Justice
If You Waive It
A federal defendant can waive the grand jury under Rule 7(b) of the Federal Rules of Criminal Procedure. You have to appear in open court and be advised of the charge and your rights before the waiver takes effect.6Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information This comes up most often in plea deals. A defendant who plans to plead guilty may not want to wait weeks or months for the next grand jury session, especially if they can’t post bail and would spend that time in custody.
How a Federal Grand Jury Works
A federal grand jury has 16 to 23 citizens drawn at random from a fair cross-section of the judicial district.7Office of the Law Revision Counsel. 28 USC Ch 121 – Juries; Trial by Jury The court appoints one juror as foreperson, who swears in witnesses, signs each indictment, and records the vote count.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Jurors typically serve up to 18 months, and a judge can extend that in six-month increments if an investigation is unfinished.9United States Courts. Types of Juries
The proceedings look nothing like a trial. The prosecutor runs the room, presenting witnesses and evidence. No judge sits in. No defense lawyer cross-examines. The accused usually isn’t there at all. The job isn’t to decide guilt; it’s to decide whether probable cause exists to put someone on trial.10United States Courts. Handbook for Federal Grand Jurors
Evidence rules are looser than at trial. In Costello v. United States (1956), the Supreme Court held that the Fifth Amendment doesn’t prescribe what kind of evidence a grand jury may hear. Hearsay, unsworn statements, and other evidence that would be inadmissible at trial can all form the basis of an indictment.11Library of Congress. Costello v United States, 350 US 359 (1956) Prosecutors also have no constitutional duty to present evidence favorable to the accused. The Supreme Court made that clear in United States v. Williams (1992).12Legal Information Institute. United States v Williams, 504 US 36 (1992) The Department of Justice has an internal policy that prosecutors should present substantially exculpatory evidence, but it’s a guideline, not a rule with teeth.13United States Department of Justice. Grand Jury
Everything that happens in the room is secret. Rule 6(e) prohibits jurors, prosecutors, interpreters, and court reporters from disclosing what occurs.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Secrecy protects people who are investigated but never charged, encourages candid testimony, and keeps suspects from fleeing or tampering with evidence before an arrest.
The Vote
After hearing the evidence, the grand jurors deliberate alone. If at least 12 of them find probable cause to believe a crime was committed and the accused committed it, they return a “true bill,” which is the formal indictment.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Probable cause is a much lower bar than the “beyond a reasonable doubt” standard used at trial. If the vote falls short, the grand jury returns a “no bill” and no charges are filed. A no bill isn’t final: double jeopardy doesn’t attach until trial begins, so prosecutors can bring the same case to a new grand jury with more evidence.10United States Courts. Handbook for Federal Grand Jurors
If You’re Called as a Witness
Grand juries have broad subpoena power. They can compel testimony and demand documents, records, and other physical evidence, and their subpoenas reach anywhere in the United States.13United States Department of Justice. Grand Jury Ignoring a subpoena without a valid legal excuse can lead to contempt.
Your Fifth Amendment right against self-incrimination goes with you into the grand jury room. You can refuse to answer any question if a truthful answer could expose you to criminal liability. What you don’t get is your lawyer beside you. Counsel waits in the hallway, and you can step out to consult, but inside the room you decide question by question on your own.10United States Courts. Handbook for Federal Grand Jurors
The privilege can also cover the act of producing documents, when handing them over would itself reveal something incriminating, such as confirming that the records exist or that you control them. It generally does not cover corporate records or business documents voluntarily created.
Immunity
The government can strip your right to refuse by getting a court order granting immunity under 18 U.S.C. § 6002. Once the order issues, you must answer, and in exchange the government cannot use your compelled testimony, or anything derived from it, against you in a later criminal case except for perjury or contempt.14Office of the Law Revision Counsel. 18 USC 6002 – Immunity Generally This is “use and derivative use” immunity. In Kastigar v. United States (1972), the Supreme Court held that it’s a sufficient substitute for the Fifth Amendment privilege, even though it’s narrower than “transactional” immunity, which would block any prosecution for the underlying offense.15Justia. Kastigar v United States, 406 US 441 (1972) If the government later prosecutes you, it has to prove every piece of its evidence came from sources independent of your compelled testimony.
Immunity isn’t routine. A U.S. attorney must get approval from the Attorney General, Deputy Attorney General, or a designated senior official before requesting the order.16Office of the Law Revision Counsel. 18 USC 6003 – Court and Grand Jury Proceedings
Refusing After Immunity
If you still refuse to testify after being granted immunity, a court can hold you in civil contempt and jail you until you comply. Under 28 U.S.C. § 1826, that confinement is capped at 18 months or the remaining life of the grand jury, whichever is shorter.17Office of the Law Revision Counsel. 28 USC 1826 – Recalcitrant Witnesses The point is to coerce compliance, not to punish, and the government has no way to extend the coercion past the statutory limit.
If You’re Being Investigated
Federal prosecutors sort the people connected to an investigation into three categories. A witness has information but isn’t suspected of wrongdoing. A subject’s conduct is within the scope of the investigation but hasn’t been pinned as likely criminal. A target is someone the prosecutor believes has committed a crime based on substantial evidence.13United States Department of Justice. Grand Jury
If you’re a target, you may receive a “target letter” naming your status and the suspected offense. A target letter is a warning sign that the grand jury may be close to a vote on indictment, and it’s the point at which people who don’t yet have a criminal defense attorney typically need one. These labels aren’t fixed: a witness can become a subject or a target as the facts develop. Prosecutors can subpoena a target to testify, but they need internal approval, and the target keeps the full Fifth Amendment privilege.13United States Department of Justice. Grand Jury
Challenging an Indictment
Getting a federal indictment dismissed is hard. The viable challenges focus on how the grand jury was constituted or how the prosecutor behaved, not on whether the evidence was strong.
- Jury composition. Under the Jury Selection and Service Act, a defendant can attack the indictment by showing that the grand jury wasn’t drawn from a fair cross-section of the community, typically by proving systematic exclusion of a recognizable group.7Office of the Law Revision Counsel. 28 USC Ch 121 – Juries; Trial by Jury
- Prosecutorial misconduct. Knowingly presenting false testimony or improperly pressuring witnesses can support dismissal, though the defendant usually has to show the misconduct was willful and caused real prejudice.
- Defective indictment. An indictment that fails to state an offense, or is so vague you can’t prepare a defense, can be challenged on its face.
What courts will not do is second-guess the quality of the evidence the grand jury heard. Arguing that the case rested on hearsay, or that the evidence was thin, will not get an indictment thrown out as long as the grand jury was properly constituted and the process wasn’t corrupted.
