How this page differs from the national grand jury page
Our federal grand jury page covers how the proceeding works in full, so read it for the general rules. This page covers the California side: which district handles your matter, which prosecutor office makes the charging call, what instructions jurors in a California courtroom would hear, and how a lawyer helps before any indictment exists.
The investigation is federal, but the court is local. Your case would land in one California district, in front of a federal judge based there, and Ninth Circuit rules would apply. Those local facts affect your next steps.
Where a defense lawyer fits in before charges
When a subpoena or target notice arrives from a grand jury, it usually means you must testify, produce records, or accept that investigators are looking at your own conduct. None of that is a charge. It does mean federal investigators know your name, and your choices now can weigh as heavily as anything that follows.
A defense lawyer at this point works in general terms as a buffer, a preserver, and an early reader of the case. The lawyer takes over all communication so agents and prosecutors stop contacting you directly. The lawyer tells you what not to touch. No statements, no deleted messages, no cleanup of books, no calls asking others to stay quiet. The lawyer finds out your status, tests any subpoena for what it really requires, and prepares you for every question or asserts your rights where the law allows. And the lawyer opens a channel with the prosecutor office, because charging decisions belong to prosecutors. Justice Department policy acknowledges the weight of that role by directing that the prosecutor must be scrupulously fair to all witnesses and must do nothing to inflame or otherwise improperly influence the grand jurors. That policy guides the prosecutor. It does not replace your own counsel.
Talk of testifying or cooperating should go through your lawyer, who can check whether an offer is genuine and have the terms put in writing. For the broader map of where these decisions get made, see our California federal courts hub.
The grand jury in brief
Do not picture a trial. A federal grand jury decides only whether prosecutors have enough to bring a federal charge. It meets in secret, you have no lawyer in the room, and you have no defense case to present. Its authority comes from the Fifth Amendment, and a federal felony case generally must pass through a grand jury before trial. The full explanation, including the exact rules and policies, is on our federal grand jury page.
The standard is probable cause, which sits far below the proof needed at trial. Because that bar is low, indictments are common once a case reaches this stage. Much of the defense work therefore happens before anyone testifies.
A panel has between 16 and 23 members, and an indictment takes at least 12 votes, even when some seats are empty. The exact rule language is on the national page.
Secrecy works differently than many people expect. Only the government's lawyers, interpreters if needed, a court reporter or recording operator, and the witness under questioning may be in the room. No judge sits there, and your lawyer waits outside. When jurors deliberate and vote, everyone else leaves, prosecutors included. Jurors and prosecutors must keep quiet, but you, as a witness, are not bound that way. Tell your own lawyer every question and every answer, promptly and fully, so that advice can come while the investigation is still underway.
No defense lawyer is seated in the room, so jurors hear one side. Do not assume anyone has told your side for you. If you have evidence that clears you, your lawyer needs a plan to show it to the prosecutor or the jurors, built before testimony starts. See grand jury subpoenas for how to respond to a demand for testimony or records.
Your status: witness, subject, or target
Prosecutors place people in three groups, and yours affects your options. A witness has information but is not suspected of wrongdoing. A subject's conduct falls within the grand jury's investigation. A target is someone prosecutors hold substantial evidence against and already view as a possible defendant. The exact definitions are quoted on our federal grand jury page.
These categories can shift. Someone who starts as a witness can become a subject, and then a target, as evidence builds, and you may not be told. So get advice even if you think you are merely a witness, and do not guess your status from how a phone call sounded. Have counsel find out where you stand before you say anything.
Justice Department policy calls for a written warning whenever a target or subject is served, and for the prosecutor to restate the warnings on the record before asking questions. In general terms, they tell you that you may decline to answer questions that would incriminate you, that your words can be used against you before the grand jury or later, and that if you have a lawyer you may step outside to consult. Known targets are also told that investigators are looking at them for a possible federal offense. The exact warning language is quoted on our federal grand jury page. If a letter has named you as a target, our target letter page is the next stop.
Policy offers targets one more protection. If you have not testified and have not asked to, prosecutors in suitable cases are encouraged to tell you ahead of time, so you can ask to appear before the grand jury. Prosecutors may not give notice in routine, clear cases, or when giving it could lead to flight, lost evidence, danger to witnesses, or delay. A target letter is often that notice. Treat it as a deadline coming closer, and respond only through counsel.
If you are called to testify. Silence, immunity, and contempt
Your rights are real, but using them safely takes a lawyer's help.
The privilege against self-incrimination. You may decline questions whose truthful answers could expose you to criminal liability, and this reaches documents you may be ordered to produce. It does not reach questions that are merely embarrassing, only those that put you at real risk of prosecution. You must raise it one question at a time, on the record, which takes skill. Refusing outright to be sworn or to enter the room is a different thing and can bring contempt.
Counsel, outside the room. Your lawyer is not allowed to sit with you or object to questions, but you can leave the room to consult as many times as necessary. Rehearse with counsel beforehand: answer only what was asked, pause before each answer, and step out when a question could create criminal risk for you, points toward another investigation, or enters a subject you planned to handle with care.
Immunity. If you invoke the privilege, the court can still order you to testify under 18 U.S.C. section 6002. After that order, you must answer, but your compelled testimony, and anything derived from it, generally cannot be used against you in a criminal case. Exceptions apply if you lie, make a false statement, or defy the order. This is called use immunity. Prosecutors remain free to rely on evidence they obtained independently. Your lawyer should decide with you whether to ask for immunity, take it, or contest it. The statute's wording is quoted on our federal grand jury page.
Contempt. If you decline to testify or hand over what the court ordered and have no valid legal ground, the court can order you confined. It ends when the proceeding or the grand jury's term ends, if you have not complied sooner, and the statute sets a ceiling of eighteen months. The purpose is to pressure you into complying, not to punish you, and release comes once you comply. Because a valid assertion of privilege and contempt sit so close together, never test the boundary without counsel guiding each refusal.
False declarations and what a California jury would hear
Section 1623 of Title 18 makes it a federal crime to knowingly make a false material declaration in a grand jury or court proceeding, or in a matter tied to one. The maximum penalty is five years in prison, along with a fine. Two words matter. The government must show you knew the statement was false, so an honest mistake or sincere belief is not enough, though proving which it was can be contested. And the statement must be material, meaning it could influence the proceeding, not trivia. Do not count on being able to retract an answer. The safest course is truthful, brief answers after preparing with counsel, or relying on the privilege when it fits.
This is where California matters. If a false declaration charge were ever tried in a California federal courtroom, jurors would be guided by model instructions written for the Ninth Circuit, not a generic national charge. The government must prove four things beyond a reasonable doubt: that you gave sworn testimony connected to a court case or a grand jury investigation; that it was false; that you knew it was false; and that the falsehood was material, meaning it could have influenced the court or the grand jury.
The Ninth Circuit instructions also draw a distinction that could only matter in a case like this. For ordinary perjury under 18 U.S.C. section 1621, the model instruction carries a corroboration paragraph rooted in the old two witness rule. For false declarations under section 1623, the Ninth Circuit comments state plainly: "A paragraph in the instruction concerning corroboration is not required when a defendant is accused of violating 18 U.S.C. § 1623." In plain terms, a section 1623 charge is easier for the government to prove than classic perjury in this one respect. Do not walk into the grand jury room counting on technical defenses you read about online.
If a false declaration conviction reached sentencing, Guideline section 2J1.3 would apply, and its base offense level is 14. It goes higher if the offense involved threats or harm to people or property aimed at procuring perjury, or if the perjury seriously disrupted the administration of justice. Those figures are starting points, not predictions. Facts can change the result a great deal, and guideline ranges are advisory. See federal sentencing for how that process works.
Finding your California district
California has four federal judicial districts, set by statute: Central, Northern, Eastern, and Southern. Your matter generally stays in the district where charges would be filed. A Los Angeles investigation belongs to the Central District, and a Sacramento investigation belongs to the Eastern District. Moving a case between districts is uncommon and requires a specific legal reason, so identify the district on your papers first.
The same statute fixes where each district holds court, so your papers tell you where you would appear:
- Northern District: San Francisco, San Jose, Oakland, and Eureka.
- Eastern District: Sacramento, Fresno, Redding, and Bakersfield.
- Central District: Los Angeles for the Western Division, Santa Ana for the Southern Division, and a site in or near Riverside or San Bernardino for the Eastern Division.
- Southern District: San Diego.
Prosecutors in each district work for that district's own United States Attorney Office, which decides charges for cases built in its area. The Central District office covers seven counties: Ventura, Santa Barbara, San Luis Obispo, Los Angeles, San Bernardino, Riverside, and Orange. The Northern District runs from Del Norte County at its northern end to Monterey County. The Southern District covers Imperial County and San Diego County. The Eastern District covers 34 counties running from the Oregon border to the Bakersfield area. Your lawyer's contact with prosecutors goes to your own district's office rather than to any national headquarters, which is one more reason to pin down your district first.
After the vote: indictment and what follows
The foreperson signs the indictment once at least 12 grand jurors agree there is probable cause, then presents it in open court to a magistrate judge. It can be kept sealed, which is why an arrest can come weeks after a vote with no warning. Once the case is unsealed, the usual steps follow, from arrest or surrender through arraignment, discovery, and motions, and possibly trial. See federal indictment for each step.
If jurors decline to indict, no one announces an acquittal. Prosecutors can keep investigating, bring the evidence back, and another grand jury could reach a different decision. Only the passage of time, plus confirmation from your lawyer, shows the risk has passed. Silence from prosecutors proves nothing.
The numbers on this page are ceilings set by statute, or starting points under the guidelines. They are not predictions for any individual. Five years is the most for a false declaration, and eighteen months is the most for civil confinement of a witness who refuses to testify. Real outcomes depend on what happened, what is charged, what proof exists, and who the judge is, so read each figure as general information only.
Practical steps: do and do not
A grand jury inquiry calls for early, careful action.
Do:
- Before you testify, give up records, or speak with agents, hire a federal defense lawyer.
- Read each subpoena the day it arrives and mark every deadline.
- Keep every record as it is: texts, email, phones, company files, and whatever the subpoena names.
- After each appearance, give your lawyer a full account of the questions and your answers.
- If you are unsure during questioning, step out and consult counsel.
Do not:
- Ignore a subpoena, miss an appearance, or hope it will go away.
- Destroy, hide, or change any record once you know of an investigation.
- Compare notes with other witnesses, match stories, or ask anyone to hold back information.
- Call the prosecutor or agents yourself to argue your way out of target status.
- Post about the case or write down facts for anyone other than your lawyer.
At the grand jury stage, charges are still being weighed and have not yet become a filing. That is when good advice counts most. Bring in counsel now, use the rights described here only through counsel, and do not swap short-term relief for a permanent record.
