Definition and Purpose of a Grand Jury

A grand jury is a group of citizens. They investigate potential crimes and decide if charges should be brought. A trial jury decides guilt or innocence. In contrast, a grand jury assesses if there is probable cause to believe a crime was committed.

Overview of Grand Jury Proceedings

Grand jury proceedings are typically conducted secretly and are led by a prosecutor. The grand jury reviews evidence and hears witness testimony. They do this before deciding whether to issue an indictment, also known as a “true bill.””

The Role of the Grand Jury

Investigative Function

The grand jury has a significant investigative role. It can gather evidence and compel testimony.

Gathering Evidence

The grand jury can subpoena documents, records, and other physical evidence. This power helps uncover the facts surrounding potential criminal activity.

Issuing Subpoenas

Subpoenas are legal orders requiring someone to testify or produce evidence. The grand jury uses them to ensure key witnesses and documents are presented.

Determining Probable Cause

The grand jury must decide if there is probable cause to charge someone with a crime. This doesn’t mean proving guilt, just that there is enough evidence for the case to proceed.

Legal Standards

Probable cause is a lower standard. It’s lower than the “beyond a reasonable doubt” requirement in trials. It means there’s a reasonable basis to believe a crime occurred and the accused may have committed it.

The Indictment Process

If the grand jury finds probable cause, it issues an indictment. This formal accusation starts the criminal trial process. If not, the case is dismissed without charges.

The Structure of a Grand Jury

Composition of the Grand Jury

Grand juries vary in size and composition.

Number of Jurors

Typically, a grand jury consists of 16 to 23 members. The exact number can vary by jurisdiction.

Selection Process

Jurors are usually selected from the same pool as trial jurors. They are picked randomly. But, they must meet specific rules. For example, they must be residents of the area and have no criminal record.

Duration of Service

Grand juries serve for a set period, which can vary.

Term Length

Terms can last a few months to a year. Jurors review many cases during their service.

Frequency of Meetings

Grand juries may meet weekly, every other week, or monthly. The schedule depends on the caseload and jurisdiction. This schedule ensures they can handle ongoing investigations efficiently.

The Grand Jury Process

Initiation of Proceedings

Grand jury proceedings begin when prosecutors refer a case.

Case Referral by Prosecutors

Prosecutors present cases to the grand jury. They believe there is enough evidence for further investigation. They outline the case and the alleged crimes.

Initial Review of Evidence

The grand jury reviews the early evidence. They do this to get the basic facts and context of the case. This preliminary review sets the stage for deeper investigation.

Presentation of Evidence

Evidence is key in grand jury proceedings. The prosecutor presents it.

Role of the Prosecutor

The prosecutor guides the grand jury, presenting evidence and questioning witnesses. The goal is to build a strong case for probable cause.

Types of Evidence Presented

Documents, physical objects, and digital records can be evidence. The prosecutor may also present summaries of police reports and other investigative materials.

Witness Testimonies

Witnesses play a crucial role in grand jury proceedings.

Subpoenaed Witnesses

Witnesses can be compelled to testify through subpoenas. This ensures crucial information is provided to the grand jury.

Immunity and Testimony

Witnesses may be granted immunity, protecting them from prosecution based on their testimony. This encourages honest and complete disclosure of information.

Secrecy in Grand Jury Proceedings

Reasons for Confidentiality

Secrecy is a hallmark of grand jury proceedings. It serves several important purposes.

Protecting Witnesses

Confidentiality protects witnesses from intimidation or retaliation. It encourages them to speak freely and truthfully.

Preventing Tampering with Evidence

Keeping proceedings secret helps prevent the destruction or tampering of evidence. This ensures the integrity of the investigation.

Legal Requirements

Strict rules govern the secrecy of grand jury proceedings.

Secrecy Rules

Jurors, prosecutors, and other participants are legally bound to keep proceedings’ details confidential. Breaching this secrecy is a serious offense.

Consequences of Breaching Secrecy

Violating grand jury secrecy can lead to legal penalties, including fines and imprisonment. It undermines the integrity of the justice system.

Standing tall with rights: individuals in grand jury proceedings are protected by legal rights that help ensure a fair and just process.

Rights of Individuals in Grand Jury Proceedings

Rights of the Accused

The rights of the accused at grand juries differ a lot from at trials.

Lack of Representation

Unlike in a trial, the accused has no right to have an attorney in the grand jury room. The prosecutor runs the show. The defense attorney can only advise the accused outside the room.

No Right to Present Evidence

The accused generally cannot present evidence or witnesses. The grand jury only hears what the prosecutor presents, making it a one-sided process.

Rights of Witnesses

Witnesses have their own set of rights and protections during grand jury proceedings.

Legal Representation

Witnesses are allowed to have an attorney. Yet, like the accused, the attorney cannot be present in the grand jury room. Instead, the witness can step out to consult their lawyer.

Protection Against Self-Incrimination

Witnesses can use the Fifth Amendment to avoid answering incriminating questions. This right ensures they aren’t forced to provide evidence against themselves.

Paths diverge: grand jury proceedings conclude with one of two outcomes – an indictment, leading to a criminal trial, or a “no bill” decision, meaning insufficient evidence to proceed with charges.

Outcomes of Grand Jury Proceedings


The grand jury’s primary decision is whether to indict the accused.

True Bill

If the grand jury finds probable cause, they issue an indictment or “true bill.” This formal charge means the case can go to trial.

No Bill

If the grand jury doesn’t find enough evidence, they issue a “no bill.” This means no charges are filed, and the case is dismissed.

Post-Indictment Procedures

Once an indictment is issued, several steps follow before a trial can begin.


The accused appears in court to hear the charges formally read. They enter a plea of guilty, not guilty, or no contest.

Pre-Trial Motions

Before the trial, both sides may file motions. These include requests to dismiss charges. Or, to suppress evidence. Or, to compel specific actions from the other side.

Differences Between Grand Juries and Trial Juries

Grand Jury vs. Petit Jury

It is understanding the distinction between grand and trial juries (petit juries).

Purpose and Function

  • Grand Jury: Decides if there’s enough evidence for a trial. They don’t decide guilt or innocence.

  • Petit Jury: Determines the guilt or innocence of the accused at trial.

Proceedings and Deliberations

  • Grand Jury: Proceedings are secret, led by the prosecutor, and the defense has limited involvement.

  • Petit Jury: Proceedings are public, with both the prosecution and defense presenting their cases. Deliberations are based on the trial’s evidence.

A system under scrutiny: the grand jury process has faced criticism and controversy, with concerns ranging from lack of transparency to potential bias, leading some to call for reforms or alternatives.

Criticisms and Controversies

Potential for Prosecutorial Overreach

The grand jury system has faced criticism for various reasons.

Lack of Defense Representation

Without defense attorneys present, the process can heavily favor the prosecution. This imbalance can lead to biased outcomes.

Influence of the Prosecutor

Prosecutors have significant control over what evidence is presented. This influence can sometimes lead to an indictment, even with weak evidence.

Calls for Reform

Reforms have been proposed to address these criticisms.

Transparency Issues

Critics argue for more transparency in grand jury proceedings. Some suggest allowing defense attorneys to be present. Or, they could publicize parts of the proceedings.

Proposed Changes

Proposals for change include:

  • Allowing the defense to present evidence

  • Implementing independent oversight of grand jury processes

  • Providing more explicit guidelines on grand jury instructions
