Grand Jury Investigations

A grand jury is a powerful tool that federal prosecutors can use to investigate and gather information about white collar crimes. The grand jury has the power to subpoena witnesses to testify and produce documents for review in an effort to gainformation about an individual’s involvement in a white collar crime and to see if there is enough evidence to indict that person.

Grand jury procedures

In addition to traditional police investigations, federal prosecutors often employ the powers of a grand jury to investigate white collar crimes. The federal prosecutor, generally an Assistant United States Attorney (AUSA), can use the grand jury to gather documents and obtain testimony regarding the crime.

The federal prosecutor acts as the main legal advisor to the grand jury, decides which witnesses will be called (the grand jury can also issue additional subpoenas), questions the witnesses (grand jurors can also ask questions) and exercises control over whether immunity will be granted in a particular situation.

There are three categories of people the prosecutor and grand jury are interested in: witness, subject and target. A witness has information related to the investigation, but is not under any suspicion. A target is someone who will probably be charged. A subject lies between a target and a witness. It is someone who has engaged in suspicious conduct, but the prosecutor is not sure if the commission of a crime can be established so he or she is looking for more information. A witness does not have a constitutional right to have counsel present during the grand jury proceedings.


Federal grand jury subpoenas are issued pursuant to Rule 17 of the Federal Rules of Criminal Procedure. The subpoena will generally command the witness to attend and give testimony before the grand jury at a particular time set by the prosecutor. The subpoena can also demand that the witness produce certain categories of documents.

Generally, if you receive a subpoena to testify before the grand jury, it is because the prosecutor believes that you have information or documents that could be relevant to the ongoing investigation. In many cases, the subpoena requests documents kept in the ordinary course of business, and there is really no reason to believe that you are under investigation. If you receive a grand jury subpoena, it is important to have a lawyer experienced in white collar matters review it and explain it to you. Depending on the circumstances, you may be able to assert one or more privileges, such as the attorney-client privilege, regarding documents that have been subpoenaed.

Advantages of the grand jury

The grand jury has several advantages over normal police investigations, including:

  • The power to subpoena individuals to appear before it or produce documents
  • Lay participation
  • Closed proceedings
  • Grants of immunity to witnesses
  • Secrecy
  • The federal prosecutor’s role in leading the investigation
