The Grand Jury: America’s Unique Pre-Trial System

Meta Description: The Grand Jury’s Core Function

The Grand Jury is a fundamental, yet often misunderstood, institution in the U.S. criminal justice system. Unlike a trial jury, its role is not to determine guilt but to act as a crucial preliminary check, assessing whether enough evidence exists to formally charge an individual with a serious crime (issuing an indictment).

The image of a trial jury—a group of citizens weighing evidence to deliver a verdict of guilty or not guilty—is iconic in legal dramas. However, a separate and equally vital body operates largely out of the public eye: the Grand Jury. This institution, enshrined in the Fifth Amendment of the U.S. Constitution, serves as a gatekeeper for the federal criminal justice system and in many state systems, ensuring that prosecutions are not arbitrary or unfounded. Understanding the Grand Jury is essential to grasping the preliminary steps of a criminal case, as it holds the power to launch or halt a serious legal proceeding.

What Exactly is a Grand Jury?

A Grand Jury is a group of ordinary citizens impaneled to investigate potential criminal conduct and determine whether criminal charges should be brought. Its primary function is accusatory and investigatory, not judicial.

Key Distinction: Grand Jury vs. Petit Jury

The Grand Jury (from the French grand, meaning large) typically consists of 16 to 23 members. A petit (trial) jury, by contrast, is smaller and determines guilt or innocence after a trial. The Grand Jury operates solely on the issue of Probable Cause.

The Dual Role: Sword and Shield of Justice

Historically and today, the Grand Jury performs a delicate dual function, often referred to as both the “sword” and the “shield” of justice.

Function	Description
The Sword (Investigative)	It investigates crimes, obtaining evidence and sworn testimonies through its virtually unfettered power to issue Subpoenas for documents and witnesses. It serves as an arm of the court, assisting Government Attorneys in uncovering criminal operations.
The Shield (Protective)	It acts as a buffer between the Government and the people. It protects citizens from unwarranted or oppressive prosecution by requiring its approval before someone can be brought to trial for a serious crime.

The Indictment Process: True Bill vs. No Bill

The Grand Jury’s work culminates in a vote on the evidence presented by the Government Attorney. This is the stage where a formal charge, or the lack thereof, is determined. The standard required for action is Probable Cause, which is a lower standard than the “beyond a reasonable doubt” required for a criminal conviction at trial.

Indictment (“True Bill”): If the Grand Jury determines that there is enough evidence—i.e., probable cause—to believe a crime was committed and the accused committed it, they will vote to issue an indictment. In the federal system, at least 12 of the 16–23 jurors must concur. The filing of this indictment formally initiates the criminal prosecution process.
No Indictment (“No Bill”): If the evidence does not persuade the Grand Jury that probable cause exists, they vote a “no bill” or “not a true bill”. When this occurs, the accused is not required to plead to a criminal charge, and no trial will proceed based on that specific charge.

Tip Box: Grand Jury in the Federal System

Under the Fifth Amendment, a Grand Jury indictment is constitutionally required for a person to be prosecuted for a serious federal crime (a felony), unless the defendant chooses to waive this right. However, states have the freedom to define their own use of Grand Juries, with many utilizing a preliminary hearing before a judge instead.

The Rule of Secrecy and Limitations

A distinctive feature of Grand Jury proceedings is their strict secrecy, which is codified in rules like Federal Rule of Criminal Procedure 6(e).

Why the Secrecy?

The secrecy serves several crucial purposes:

Protecting Reputations: It shields individuals who are investigated but ultimately not charged from public scrutiny and damage to their reputation.
Witness Cooperation: It encourages witnesses to testify more freely and completely without fear of retaliation or intimidation.
Preventing Flight: It keeps the investigation confidential, preventing suspects from fleeing the jurisdiction or tampering with evidence.

Caution: The Ex Parte Nature

Grand Jury proceedings are ex parte, meaning only the Government Attorney presents evidence, and there is no defense presentation or cross-examination. A witness called to testify cannot have their Legal Expert present with them in the federal Grand Jury room during their testimony, though they may consult with a Legal Expert outside the room.

Summary of Grand Jury’s Importance

The Grand Jury serves as a preliminary investigative and charging body, exclusively focused on whether probable cause exists to bring criminal charges, specifically in felony cases at the federal level.
It is comprised of 16 to 23 citizens and operates under strict secrecy to protect the integrity of the investigation and the reputation of the accused.
The Grand Jury’s decision results in either a “True Bill” (indictment) or a “No Bill,” effectively initiating or halting the prosecution of a serious crime.
While its primary function is accusatory, its historical and ongoing role as a “shield” against governmental overreach remains a cornerstone of the Fifth Amendment right.

Card Summary: Grand Jury at a Glance

An essential component of the U.S. Criminal Procedures system, the Grand Jury acts as a non-trial body to scrutinize evidence presented by the Government Attorney. Its function is to check the power of the government by requiring a civilian majority (12 of 16-23 members) to find Probable Cause before an indictment can be filed for a federal felony. It is neither a finding of guilt nor innocence, but a determination of whether the case is strong enough to proceed to trial.

Frequently Asked Questions (FAQ)

Q1: Is a Grand Jury required in all U.S. states?

A: No. While the Fifth Amendment mandates a Grand Jury indictment for federal felonies, the requirement does not apply to states (it has not been incorporated through the Fourteenth Amendment). As a result, roughly half of all states use an indictment, while others primarily use a preliminary hearing or prosecutor’s information to initiate felony charges.

Q2: Can the accused or their Legal Expert present evidence to the Grand Jury?

A: In the federal system, the proceedings are non-adversarial. The accused has no right to attend the proceedings, present evidence, or cross-examine witnesses. The only people present during witness testimony are the Grand Jurors, the Government Attorney, and a court reporter. Some states have different rules, allowing the accused to testify or their Legal Expert to be present in the room for advisory purposes, but this varies significantly by jurisdiction.

Q3: What happens if a Grand Jury votes a “No Bill?”

A: If a “No Bill” is returned, the criminal charge against the person is dismissed, and they are not formally charged with that crime. However, this does not necessarily prevent a government attorney from presenting the same case to a new Grand Jury or pursuing charges through other available legal procedures, depending on the jurisdiction.

Q4: How long do Grand Juries typically serve?

A: The term of service varies. Federal Grand Juries generally serve for 18 months, though a court may grant an extension, up to 24 months in some cases. State Grand Juries may have terms ranging from a few months up to a year, depending on state or local rules.

The Grand Jury remains a uniquely American institution, acting as a historical and operational hinge point in the criminal justice system. Its power—to investigate broadly and to act as a popular check on governmental authority—makes it an indispensable part of how serious crimes are addressed in the United States.
