In the United States legal system, the concept of a jury is fundamental, but it manifests in different forms, each with distinct responsibilities. While many are familiar with the petit jury, also known as a trial jury, another crucial body exists within the judicial process: the grand jury. This article delves into the specifics of a grand jury, clarifying its purpose, composition, and how it differs from its petit jury counterpart.
A grand jury is essentially a group of citizens empowered to investigate potential criminal conduct and determine whether there is sufficient evidence to bring criminal charges against an individual. Unlike a petit jury, which decides guilt or innocence at trial, a grand jury’s role is investigatory and accusatory. They do not determine guilt or innocence; instead, they decide if there is probable cause to believe that a crime has been committed and that a specific person committed it.
If a grand jury finds probable cause, it issues an indictment, which is a formal accusation that allows the case to proceed to trial. Without an indictment from a grand jury in many federal felony cases, the accused cannot be formally charged with a crime and proceed to trial.
Grand juries possess several unique characteristics:
-
Size and Composition: Grand juries are larger than petit juries, consisting of 16 to 23 citizens. These individuals are drawn from the community and represent a cross-section of society.
-
Private Proceedings: Grand jury proceedings are conducted in secrecy. This confidentiality is crucial to protect the reputations of those under investigation, to encourage witnesses to testify freely, and to prevent potential suspects from fleeing or tampering with evidence. Only the prosecutors, witnesses, and grand jurors are present; judges and defense attorneys are not typically allowed in the grand jury room.
-
Term of Service: Grand jurors typically serve for a longer period than petit jurors, often serving for 18 months, and in some cases, up to 24 months with a judge’s extension. This extended term allows them to consider multiple cases and investigations.
-
Scope of Review: Unlike petit juries who are empaneled for a single trial, grand juries review numerous cases during their service. They meet intermittently, not daily, depending on the caseload in their district. A grand jury in a busier district might meet several days a week, while one in a less active district might meet only a few days a month.
In summary, the grand jury is a critical component of the US criminal justice system. It acts as a check on prosecutorial power, ensuring that there is a basis for criminal charges before an individual is subjected to the ordeal of a criminal trial. While it does not decide guilt or innocence, the grand jury’s determination of probable cause is a vital step in the process of bringing serious criminal cases to court.
