In California, a grand jury is a legal process common in federal and serious state felony cases whereby a jury of citizens from the community convenes to evaluate whether there is sufficient evidence to charge or indict you for a criminal offense. 1
Grand juries are different from the jury (technically known as the “petit jury”) at a criminal jury trial. Whereas the petit jury decides whether you are guilty or innocent—the grand jury’s job is just to determine whether there is probable cause to believe that you may have committed the crime. 2

In California law, the grand jury is an independent body made up of a specified number of citizens of a particular county, whose job is to perform the following functions:
In short, grand juries are an arm of the court. In this article, we will focus on the first of these tasks—the criminal function of grand juries, not their civil function.
In some California counties (such as Placer County 4 ), the same jury focuses on both criminal and civil matters. Though most large counties (such as Contra Costa County, 5 Los Angeles County, 6 and San Francisco County 7 ) divide the two functions between different groups. 8
California prosecutors must bring felony charges in one of two ways:
Unlike a preliminary hearing, grand juries are held before you appear for an arraignment (the first step in the California criminal court process).
In California, the vast majority of felony charges are brought through the preliminary hearing/information process—not through grand juries and criminal indictments. 11
District attorneys are more likely to use the grand jury indictment process if any of the following are true:
In contrast to California, where most criminal charges do not originate in the indictment process—the majority of federal felony charges are brought after an indictment.
This is because the Fifth Amendment to the United States Constitution requires that all prosecutions for “infamous” crimes come through grand juries. 13
However, federal misdemeanors can be charged through an information—they do not require a jury to issue an indictment. 14
Also, federal felonies may be charged without an indictment proceeding if you waive the right to be prosecuted in this way. 15
In theory, grand juries are supposed to make an objective determination of whether there is enough evidence to try you for a crime.
They are supposed to be not just a “sword” to help the government prosecute criminals—but also a “shield” protecting you from unjustified criminal charges. 16
In reality, it does not always work this way. The jury hears only one side of the story—the prosecutor’s side. Under these circumstances, there is a real danger that it will function only as a sword, not as a shield—and will vote to bring criminal charges that never should have been brought. 17
Unlike the juries in criminal or civil trials, which serve only for that one trial, grand juries are often formed to sit for a period of time rather than a particular matter. During this period of time, they may hear a number of indictment cases. 18
California grand juries must have at least the following number of members:
Criminal grand juries in California are selected at random from the list of people eligible to serve on a “regular” jury (“petit jury”) in a criminal or civil trial. 20 Grand jurors should represent a cross-section of the population that is eligible to serve on a jury at a jury trial. 21
In order to be eligible for grand jury service, a person must meet the following requirements:
In addition, each grand juror must meet the following “negative qualifications”:
Indictment proceedings are very different from ordinary criminal trials in three ways:
If—after weighing all the evidence presented to it—the jurors believe that the evidence would warrant your criminal conviction by a trial jury, it may issue an indictment against you. 28
The vote of the jurors does not need to be unanimous for an indictment to be issued. Instead, the following numbers of votes are needed:
In a typical proceeding, the district attorney will present evidence to the jurors, to show that you are guilty of the crime. This evidence may include:
The California evidence rules that apply to California criminal trials also apply to California grand juries 31 –with one major exception.
Specifically, the hearsay rule does not apply in indictment proceedings to the sworn testimony of a law enforcement officer about a statement someone else made out of court, as long as the law enforcement officer either:
The jurors are not required to hear any evidence in your favor. Though if they have reason to believe that there is evidence available that tends to prove you are not guilty, it can order that evidence to be produced. 33
As you can see from the discussion above, your rights as the potential defendant in a criminal grand jury proceeding are very limited. Though that does not mean that they are nonexistent.
The most important right that you enjoy is set out in Penal Code 939.71 PC. This law provides that the prosecutors must disclose any evidence they are aware of that tends to prove that you are innocent (this is known as “exculpatory evidence”). 34
If the prosecutor does not fulfill this obligation at your proceeding, then you may be able to get the charges against you dismissed through a Penal Code 995 motion. 35
Federal grand juries must have sixteen (16) to twenty-three (23) members. 36 At least twelve (12) of the jurors must vote to issue an indictment. 37
The members of federal grand juries are also supposed to represent a fair cross-section of the community where the proceeding will take place. Therefore, like California grand juries, they are selected at random from federal jury lists. 38
Only the following people may be present at the proceeding:
As with California grand juries, you are not typically present at the proceeding—and the proceeding takes place in secret. 40
If you receive a subpoena to testify before a grand jury as a witness, there are a few important things to keep in mind.
