An indictment is a formal written accusation issued by a grand jury, stating that enough evidence exists to put a person on trial for a serious crime. In the federal system, the Fifth Amendment requires a grand jury indictment before anyone can be prosecuted for a felony.1Congress.gov. U.S. Constitution – Fifth Amendment It is not a finding of guilt. It means a panel of citizens reviewed the government’s evidence and agreed there was probable cause to move forward.
When an Indictment Is Required
The Fifth Amendment says no person shall be “held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury.”1Congress.gov. U.S. Constitution – Fifth Amendment Courts have read “infamous crime” to cover all federal felonies. A federal prosecutor cannot bring a felony case to trial on their own authority — a grand jury has to agree first. Members of the military facing charges under the military justice system are the exception.
For federal misdemeanors, prosecutors can file charges directly through a document called an “information,” which skips the grand jury entirely.2United States Department of Justice. Charging A defendant can also waive the right to a grand jury on a felony, which sometimes happens as part of a plea agreement, allowing the government to proceed by information in that case too.
State practice varies. The Supreme Court has held that the Fifth Amendment’s grand jury requirement applies only to the federal government, not to state prosecutions. Some states use grand juries for all felonies, others let prosecutors file felony charges by information after a preliminary hearing before a judge, and some permit either method.
What an Indictment Contains
Federal Rule of Criminal Procedure 7 governs what the document must say. It has to be a plain, concise written statement of the facts that make up the alleged crime.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information The description tells the defendant which actions led to the charges, in enough detail to prepare a defense.
Each count must cite the specific statute the defendant allegedly violated.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information A mail fraud count would reference 18 U.S.C. § 1341; a drug distribution count would cite 21 U.S.C. § 841. Those citations define the elements the government has to prove at trial.
Two signatures make the indictment valid. An attorney for the government signs it under Rule 7,3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information and the grand jury foreperson signs under Rule 6 to confirm the grand jury voted to bring the charges.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury The foreperson also records how many jurors agreed, but that tally stays sealed unless a court orders it disclosed.
How a Grand Jury Decides
A federal grand jury has 16 to 23 citizens.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury It is not the kind of jury that decides guilt or innocence. It hears only the government’s side. There is no judge in the room, no defense attorney cross-examining, and no defendant presenting evidence. Prosecutors call the witnesses, show the documents, and explain the law.
The proceedings are secret. Grand jurors, interpreters, court reporters, and government attorneys are all barred from disclosing what happens inside the room, and violations can be punished as contempt.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Secrecy encourages witnesses to testify candidly and protects the reputation of people who are investigated but never charged.
The question before the grand jury is whether there is probable cause to believe a crime was committed and that the defendant committed it.5United States District Court Middle District of Florida. Handbook for Federal Grand Jurors Probable cause is a far lower bar than the “beyond a reasonable doubt” standard used at trial. The grand jury is not supposed to weigh credibility or resolve conflicting testimony. It is a screening step: is there enough here to justify a trial?
At least 12 jurors must agree before an indictment can issue.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury If they reach that number, they return a “true bill” and the indictment is filed with the court. If not, they return a “no bill,” meaning no charges from that grand jury. A no bill does not necessarily end the investigation; prosecutors can go back later with more evidence to the same or a different grand jury.6United States District Court Eastern District of Missouri. Handbook for Federal Grand Jurors Because the standard is low and the defense has no role, indictment rates in federal cases are very high. That is one reason an indictment should never be read as a conviction.
Sealed Indictments
Not every indictment becomes public right away. A judge can order one kept under seal until the defendant is arrested or appears in court. While it is sealed, the clerk locks it away and no one may reveal its existence except as needed to carry out an arrest warrant.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury
Sealed indictments are common when the government is concerned a defendant might flee, destroy evidence, or intimidate witnesses if they learned about the charges. They also appear in large conspiracy cases where multiple people need to be arrested at the same time. Once the defendant is in custody or has surrendered, the seal is usually lifted and the indictment becomes a public court record.
What Happens After the Indictment Is Filed
After filing, the court issues either an arrest warrant or a summons.7Legal Information Institute. Federal Rules of Criminal Procedure Rule 9 – Arrest Warrant or Summons on an Indictment or Information A warrant lets law enforcement take the person into custody. A summons orders the defendant to appear by a set date. Ignore a summons and the court will issue a warrant.
The first court appearance is the arraignment. The court makes sure the defendant has a copy of the indictment, reads or summarizes the charges, and asks for a plea — typically guilty, not guilty, or no contest.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 10 – Arraignment Most defendants plead not guilty at this stage, even when plea negotiations are already underway.
The court also decides whether to release the defendant pending trial or hold them in custody. Under federal law, the judge weighs the seriousness of the charges, the weight of the evidence, the defendant’s ties to the community, criminal history, employment, and whether the defendant poses a danger to others.9Office of the Law Revision Counsel. 18 U.S.C. 3142 – Release or Detention of a Defendant Pending Trial Release often comes with conditions: travel restrictions, electronic monitoring, drug testing, or regular check-ins with a pretrial services officer. If no set of conditions can ensure the defendant’s appearance or protect the community, the defendant is detained until trial.
How Long the Government Has to Indict
The government cannot wait indefinitely. For most federal crimes, an indictment must be filed within five years of the alleged offense.10Office of the Law Revision Counsel. 18 U.S.C. 3282 – Offenses Not Capital Some financial fraud offenses carry a ten-year window, and capital crimes like murder have no time limit at all. If the deadline passes without an indictment, the defendant can move to have the charges dismissed.
For ongoing conduct like a long-running conspiracy, the clock generally does not start until the last criminal act in the scheme. A conspiracy that stretched over a decade can still be charged if the indictment is filed within five years of the final act.
Challenging an Indictment
An indictment is not bulletproof. Defendants can move to dismiss on several grounds. A statute-of-limitations challenge is the most direct: if the indictment was filed too late, the case is dismissed regardless of the evidence. A defendant can also argue the indictment fails to state a federal offense, meaning the facts alleged, even if entirely true, would not actually violate the statute cited.
Other challenges target the grand jury itself. If the panel was improperly composed, if jurors were biased against the defendant, or if the prosecutor engaged in misconduct during the proceedings, those issues can support a dismissal motion. Courts take grand jury integrity seriously, but the secrecy of the proceedings makes these challenges hard to win; the defense rarely has access to transcripts or to evidence of what happened inside the room.
Prosecutors also have the option of returning to a grand jury for a “superseding indictment” that replaces the original. Superseding indictments are used to add new charges, drop weak ones, or add newly identified defendants. Once the original statute-of-limitations period has run, a superseding indictment can narrow the charges but not expand them beyond what the original covered.
