An indictment is a formal written accusation issued by a grand jury that charges a person with a serious crime after the jurors review the prosecutor’s evidence and find probable cause to believe the person committed it. The clearest indictment definition in criminal law is this: it is the charging document that opens a felony case, not proof of anything the defendant did. In the federal system, the Fifth Amendment requires one before anyone can be put on trial for a felony.
What an Indictment Means for the Person Charged
Being indicted means a group of citizens, acting on evidence presented by a prosecutor, decided there was enough reason to move the case forward. It does two things at once. It tells the defendant exactly what conduct is alleged and which laws were allegedly broken, and it shifts the case out of investigation and into court.
What it does not do is prove guilt. An indictment carries zero evidentiary weight at trial, and a jury never sees it used to establish that the defendant did anything. The prosecution still has to prove every element of the crime beyond a reasonable doubt. The grand jury’s work is a screening step, not a verdict.
How a Grand Jury Returns an Indictment
A grand jury is a group of 16 to 23 citizens summoned by the court to evaluate whether criminal charges are warranted.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury It sits for a set term and hears multiple matters. Prosecutors present witnesses, documents, and other evidence and explain why they believe a crime occurred and who was responsible.
The proceedings are one-sided by design. Defense attorneys are not allowed in the room, and there is no cross-examination. Only prosecutors, the testifying witness, interpreters, and a court reporter may be present. Sessions are also secret. Jurors, reporters, interpreters, and government attorneys are prohibited from disclosing what happens inside.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Secrecy keeps targets from fleeing or tampering with evidence, lets witnesses speak freely, and protects the reputation of people investigated but never charged.
The Probable Cause Standard
To indict, the grand jury must find probable cause to believe a crime occurred and that the person committed it. That is a far lower bar than the “beyond a reasonable doubt” standard required for conviction. The question is whether there is a reasonable basis to believe the person did it, not whether the jurors are certain.
At least 12 jurors must agree before an indictment can issue.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury When they do, the result is a “true bill” and the case advances. When the evidence falls short, they return a “no bill.” A no bill stops that charge but does not permanently bar the prosecutor from going back with new evidence.
Federal grand juries almost always indict. In fiscal 2016, the most recent year with published data, federal grand juries declined to indict just six people nationwide. Across fiscal 2007 through 2016, they refused an average of only 15 people per year.2Pew Research Center. What to Know About Federal Grand Juries The ratio reflects the structure of the process: the prosecutor controls what the jurors see, no one argues the other side, and the standard is deliberately low.
What the Indictment Document Must Say
Federal Rule of Criminal Procedure 7 sets the contents. The indictment must be a plain, written statement of the essential facts of the alleged offense, specific enough that the defendant knows what conduct is at issue.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information Each count must cite the specific statute allegedly violated. An attorney for the government must sign it, and the grand jury foreperson must sign every indictment and record how many jurors concurred.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury
These specifics do more than give notice. They draw the boundary of what the defendant is being tried for, which keeps the government from later trying the person again for the same conduct.
Indictment, Information, and Complaint
An indictment is one of three charging documents in the federal system, and the differences change what the case can do.
A criminal complaint is the simplest. It is a sworn statement by a law enforcement officer laying out the basic facts to establish probable cause for an arrest. Complaints move fast, which is why they are often used when prosecutors need to make an arrest before a grand jury can convene.
An information looks similar to an indictment on paper. It is a formal charging document that describes the alleged offense and its factual basis, but it comes directly from the prosecutor without a grand jury. A judge reviews it for probable cause. In federal court, misdemeanors and petty offenses can be prosecuted by information, but felonies generally cannot unless the defendant waives the grand jury requirement in open court.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information A felony case cannot go to trial on a complaint alone.
When an Indictment Is Required
In federal court, any offense punishable by death or by more than one year of imprisonment must be prosecuted by indictment. That covers all federal felonies other than criminal contempt. Misdemeanors carrying a year or less can proceed by information.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information
State courts work differently. The Fifth Amendment’s grand jury requirement has never been applied to the states. The Supreme Court held in Hurtado v. California (1884) that states can charge felonies without a grand jury, and that ruling still stands. Roughly 22 states require grand jury indictments to some extent for felony prosecutions. The rest allow prosecutors to file felony charges by information. Whether an indictment is involved depends heavily on where the case is filed.
Sealed and Superseding Indictments
A sealed indictment is a true bill that the court keeps hidden from the public and the defendant until a judge orders it unsealed. It has the same legal force as any other indictment. Prosecutors seek sealed indictments when early disclosure would let a target flee, destroy evidence, or warn co-defendants ahead of coordinated arrests.
A superseding indictment replaces an earlier indictment in the same case. Prosecutors file one to add charges, drop charges, add co-defendants, or correct errors. A grand jury must still approve it. Once the original statute of limitations has run, a superseding indictment can narrow the charges but generally cannot broaden them beyond what the first one covered.
Can an Indictment Be Challenged
Yes. Federal Rule of Criminal Procedure 12 allows a defendant to file pretrial motions attacking the indictment. Common grounds include failure to state an offense, lack of specificity, improper joining of offenses in a single count, charging the same offense in multiple counts, wrong venue, errors in the grand jury proceedings, vindictive or selective prosecution, and speedy trial violations. A motion challenging the court’s jurisdiction can be raised at any point while the case is pending.4Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions
If a dismissal is granted “with prejudice,” the case is over and the government cannot refile. A dismissal “without prejudice” lets the government try again, though the statute of limitations keeps running and can effectively kill a refiled case.
What Happens After the Indictment
The Speedy Trial Act requires that an indictment or information be filed within 30 days of a defendant’s arrest or service of a summons. If no grand jury has been in session during that 30-day window, the deadline extends by another 30 days.5Office of the Law Revision Counsel. 18 USC 3161 – Time Limits and Exclusions Once the indictment is filed, the defendant is arraigned. At arraignment, the court ensures the defendant has a copy of the indictment, reads or explains the charges, and asks for a plea.6Legal Information Institute. Federal Rules of Criminal Procedure Rule 10 – Arraignment
Under the Bail Reform Act of 1984, there is a general presumption that defendants should be released before trial. The government bears the burden at a detention hearing of showing the defendant is a danger to the community or a flight risk.7United States Courts. Pretrial Release and Detention in the Federal Judiciary When release is granted, the court imposes the least restrictive conditions reasonably sufficient to ensure appearance and public safety. For certain serious offenses involving violence, terrorism, or drug trafficking with heavy sentences, a rebuttable presumption of detention shifts the practical burden back onto the defendant.
