A grand jury is a group of citizens. 
In the United States, a grand jury has 16 to 23 people. They work in secret. They meet behind closed doors. They do not have a judge in the room. Instead, they listen to witnesses. They also look at evidence like papers. They must decide if there is a good reason to charge someone with a crime.
At least 12 members must agree to make a decision. If they agree, they write a paper called an indictment. This is called a "true bill." If they do not find enough proof, the case is dismissed. This is called a "no-bill."
Some places use different systems. In Japan, a group of 11 people reviews cases. They look at cases that leaders chose to drop. This helps make sure things stay fair.
A grand jury is a special group of citizens. They have a very important job in the legal system. This group investigates if a crime might have happened. They decide if there is enough evidence to start a trial. Some people call them a "shield" because they protect people from unfair charges. Others call them a "sword" because they can accuse people of crimes. 
How does a grand jury work? First, they meet in secret behind closed doors. There is no judge in the room during these meetings. Prosecutors lead the way by bringing in witnesses to speak. These witnesses must swear to tell the truth under oath. The jury also looks at physical evidence and important documents. They must decide if there is "probable cause" for a trial. This means they look for a strong reason to believe a crime occurred.
This system has a very long history. It began in England during the Middle Ages. Some say it started with an act in 1166. The name comes from a French word meaning "large." This is because they have more members than a trial jury. A trial jury is called a "petit" jury, which means "small." In the early days of the United States, grand juries did many things. They even helped pass public policy and approve taxes.
In the United States, a federal grand jury has 16 to 23 members. To make a decision, at least 12 jurors must agree. If they agree, they write a document called an indictment. They call this a "true bill." If they do not find enough proof, they write "not a true bill." This is also called being "no-billed." In 1974, a grand jury indicted seven White House aides. In 1998, President Bill Clinton had to testify before one too.
Other countries use systems that are a bit different. In Japan, there is a group called the Prosecutorial Review Commission. It has 11 randomly selected citizens on a six-month term. They look at cases that prosecutors chose to drop. This helps make sure public officials are acting fairly. Liberia also uses grand juries to decide on serious crimes. These different ways show how people all over the world try to make justice work.
A grand jury is a group of citizens empowered by law to conduct legal proceedings. Their primary role is to investigate potential criminal conduct within a specific area. They must determine whether there is enough evidence to bring formal criminal charges against a person. This process is unique because it serves two different purposes. It acts as an investigatory tool to gather facts and an accusatory tool to initiate legal action. Because they represent regular people, grand juries allow the community to participate directly in the administration of justice.

The mechanism of a grand jury involves several specific steps. First, the proceedings are usually started at the request of a government prosecutor. These meetings are held in secret behind closed doors. There is no presiding judge present during these deliberations. Prosecutors are responsible for arranging for witnesses to appear and testify. These witnesses must provide sworn testimony under oath. The grand jury also has the power to subpoena physical evidence or compel people to testify. This allows the jury to review documents and other important evidence to build a complete picture of a situation.
Grand juries function through two distinct modes of accusation. The first is a formal written statement called an indictment. An indictment must describe the specific offense along with the time and circumstances of the act. It must also identify the person being accused with certainty. The second mode is less formal and is known as a presentment. A presentment is often a spontaneous act by the grand jury itself. To move forward with either an indictment or a presentment, at least twelve jurors must agree. If the jury finds the accusation credible, they write "a true bill" on the document. This is then signed by the foreperson and presented to the court publicly. If they do not find the evidence sufficient, they write "not a true bill," which is also called being "no-billed."
The history of the grand jury stretches back to the Middle Ages in England. Some historians trace its origins to the Assize of Clarendon in 1166, an act passed by King Henry II. Others suggest that the concept of a trial jury was brought to England by the Normans. The name "grand jury" comes from the French word "grand," which means large. This distinguishes them from the "petit jury," or small jury, used in standard trials. In the early years of the United States, grand juries held even more power. They were often used to approve public policy, taxes, or government expenditures. In Ireland, grand juries even functioned as local government authorities until 1898.
In the modern United States, the size and rules of grand juries can vary. A federal grand jury typically consists of 16 to 23 members. In the state of Virginia, regular or special grand juries may have fewer members. The Fifth Amendment to the U.S. Constitution requires a grand jury indictment for capital or infamous crimes. While all states have provisions for grand juries, only about half of the states currently employ them. In six states, including Oklahoma and Nevada, citizens can even circulate a petition to impanel a grand jury. This system acts as both a "shield" to protect people from unfair prosecution and a "sword" to accuse those who break the law.

Other nations use similar but different systems to ensure legal fairness. In Japan, the government uses the Prosecutorial Review Commission, or Kensatsu Shinsakai. This system was created in 1948 under the influence of the Allies after World War II. A commission is made up of 11 randomly selected citizens serving six-month terms. Unlike American grand juries, which decide if a case should start, this commission examines cases that prosecutors have already decided to drop. This helps prevent misconduct by public officials. In Liberia, grand juries remain a constitutional requirement for serious crimes, such as capital offenses.
Grand juries connect to broader ideas about government power and civil rights. They serve as a check on the power of the state by involving lay citizens in the legal process. For example, in 1974, a grand jury indicted seven White House aides during the Watergate investigation. In 1998, President Bill Clinton became the first sitting president required to testify before a grand jury. These instances show how the institution can reach even the highest levels of leadership. By requiring a group of citizens to agree on charges, the system attempts to balance the need for law enforcement with the protection of individual rights.
