Federal Grand Jury — What It Is And How It Works

What is a Federal Grand Jury?

A federal grand jury is an investigative tool used in the United States to determine whether there is probable cause to believe that a crime has been committed and to issue indictments. This stage of the federal criminal process typically follows the initial investigation conducted by law enforcement or other government agencies, such as the FBI or DEA.

Grand juries are convened under Federal Rule of Criminal Procedure 6, which outlines the procedures for their selection, swearing in, and operation. The grand jury stage is an essential part of the federal criminal procedure timeline, coming after the initial investigation but before formal charges can be brought against a defendant.

The Governing Rules

The primary rules governing federal grand juries are found within Federal Rule of Criminal Procedure 6 and Rule 7. Additionally, local court rules may supplement these federal guidelines. Case law also plays a significant role in interpreting the application of these rules.

What Happens Step by Step in Practice?

The process of a federal grand jury investigation typically unfolds as follows:

  1. Investigation and Evidence Gathering: Government agencies gather evidence to support the need for an indictment.
  2. Selection of Grand Jury Members: Potential jurors are selected through random sampling from voter registration lists or driver's license records, adhering to Federal Rule 6(a).
  3. Grand Jury Induction and Oath Swearing: The grand jury members are officially sworn in by a federal judge.
  4. Evidence Presentation: Prosecutors present evidence to the grand jury, often including witness testimony under oath. This phase can last weeks or months.
  5. Voting on Indictments: If there is probable cause that a crime has been committed based on the presented evidence, the grand jury votes to issue an indictment against one or more individuals.
