Witness Intimidation in California: Laws, Penalties, and Defenses

Witness intimidation in California is a crime under Penal Code 136.1, which makes it illegal to prevent or try to prevent anyone from reporting a crime, cooperating with prosecutors, or testifying in court. It’s a wobbler: prosecutors can charge it as a misdemeanor carrying up to a year in county jail, or as a felony carrying two, three, or four years in state prison when force, threats, conspiracy, a prior conviction, or payment is involved.¹ The attempt alone is enough. The witness doesn’t have to actually be scared, back out, or even take the threat seriously.

What the Law Prohibits

Penal Code 136.1 covers two kinds of conduct. The first makes it a crime to knowingly and with ill intent prevent or try to prevent a witness or victim from attending or testifying at any trial, hearing, or legal proceeding. The second is broader: it reaches attempts to discourage a crime victim or witness from reporting the crime to police, from seeking prosecution, or from helping bring about an arrest.¹ You don’t need to make an explicit threat. Pressuring someone not to call the police after they’ve seen a crime can fall within the statute.

A detail that trips people up: the attempt itself is the offense. Whether the witness changed their behavior, took you seriously, or even heard you clearly is irrelevant to whether the elements are met.¹

Who Counts as a Witness or Victim

The protected category is wider than most people assume. A “witness” is anyone with knowledge about facts related to a crime, anyone whose sworn statement has been or could be received as evidence, anyone who has reported a crime to law enforcement, or anyone served with a subpoena in state or federal court. A “victim” is anyone there is reason to believe a crime has been committed or attempted against. Formal listing in a case file is not required. Having relevant information is enough.

Misdemeanor or Felony: What Determines the Charge

As a straight charge under subdivisions (a) and (b), witness intimidation is a wobbler. Charged as a misdemeanor, the maximum is one year in county jail, plus a possible fine of up to $1,000 under California’s general misdemeanor fine statute.²

The charge becomes a straight felony under subdivision (c) when any of the following applies:

The act is accompanied by actual force or an express or implied threat of violence against the witness, victim, any third person, or their property.
The act is carried out as part of a conspiracy.
The defendant has a prior conviction for witness intimidation under California law, federal law, or the law of another state.
The defendant acted for money or other consideration at someone else’s request. Everyone involved in that arrangement faces felony charges.

A felony conviction under subdivision (c) carries two, three, or four years in state prison, with three years as the presumptive middle term unless the court finds aggravating or mitigating factors.¹ The court may add a fine of up to $10,000.²

Related Charges You May Also Face

Witness Bribery

Bribery is a separate felony. Penal Code 137 makes it a felony to offer or promise anything of value to a witness in order to influence their testimony or what they tell law enforcement.³ Penal Code 138 adds a companion offense for bribing a witness to skip a trial or hearing entirely, and the witness who accepts the bribe faces felony charges too.⁴

Retaliation After the Fact

Intimidation happens before or during a case. Retaliation happens after. Penal Code 140 targets anyone who uses force or threatens violence against a witness, victim, or their property because that person already cooperated with police or prosecutors. The conduct can include property damage, harassment, or threats against the witness’s family. Retaliation is a wobbler carrying up to one year in county jail as a misdemeanor or two, three, or four years in state prison as a felony.⁵

A separate wobbler under Penal Code 139 applies to credible threats made by someone with a prior qualifying violent felony conviction against witnesses or victims from the case that produced that conviction, with the same two-to-four-year prison range and the possibility of consecutive sentencing for repeated threats.

Defenses That Work (and Ones That Don’t)

The statute builds in a presumption for one common situation. If the defendant is a family member who acted in an effort to protect the witness or victim, the law presumes they acted without the required ill intent.¹ The presumption is rebuttable, but it shifts a meaningful burden to the prosecution. It matters most in domestic violence cases where one family member urges another not to testify out of genuine concern.

Beyond that presumption, the usual defenses go to the elements: whether the defendant actually knew the person was a witness, whether their conduct was really intended to dissuade rather than being part of a difficult conversation, and whether the prosecution can prove the mental state the statute requires. Two arguments the statute explicitly forecloses: that the attempt failed and that no one was physically harmed. Neither matters.¹

Why Silencing a Witness Can Backfire

Defendants who succeed in keeping a witness off the stand often make their trial situation worse. Under California Evidence Code section 1390, if a party intentionally makes a witness unavailable to testify, the court can admit that witness’s prior out-of-court statements, which would normally be excluded as hearsay.⁶ The prosecution must prove by a preponderance of the evidence that the defendant’s wrongdoing caused the unavailability, supported by independent corroboration beyond the unavailable witness’s own statements.

If the threshold is met, the witness’s earlier statements to police or at the preliminary hearing come in, and the defense loses the chance to cross-examine them. The evidence the defendant tried to suppress ends up in front of the jury anyway, without any ability to challenge it live.

Protection for Witnesses and Victims

Once a court knows a witness or victim is being pressured, it has several tools. Under Penal Code 136.2, a judge can issue a Criminal Protective Order requiring the defendant to stay a specified distance away, prohibiting all contact including through third parties, barring any attempt to dissuade the witness from testifying, and requiring the surrender of firearms within 24 hours.⁷ A Criminal Protective Order stays in effect as long as the court has jurisdiction over the case.

For urgent situations, a law enforcement officer can request an Emergency Protective Order from a judge available around the clock. An EPO takes effect immediately and lasts five to seven days, giving the protected person time to seek a longer-term order.⁸

For witnesses facing severe danger, the California Witness Relocation and Assistance Program, administered by the Attorney General’s Office, provides security measures and relocation support. It primarily serves witnesses endangered through their participation in gang, organized crime, human trafficking, or narcotics cases, though other high-risk situations qualify.⁹

Job protection also exists. Under Labor Code section 230, your employer cannot fire you, demote you, or retaliate against you for taking time off to appear in court as a witness in response to a subpoena. Crime victims get the same protection when taking time off to seek a restraining order or other court relief. If an employer violates this, you are entitled to reinstatement and reimbursement for lost wages and benefits.¹⁰ Give reasonable advance notice when you can; if the absence is unscheduled, you can provide documentation afterward.

When the Case Is Federal

Everything above is California law. If the underlying case involves a federal crime or federal court proceeding, witness tampering falls under 18 U.S.C. § 1512 and the exposure is much higher: up to 30 years for using physical force, up to 20 years for threatening it, and up to 20 years for non-violent intimidation or misleading conduct aimed at influencing testimony. The federal statute also reaches corruptly persuading someone to withhold documents, destroy evidence, or evade a subpoena.¹¹

Reporting Intimidation

If you’re being pressured not to testify or report a crime, contact local law enforcement or the prosecutor’s office handling the case. The sooner the court knows, the sooner it can impose or modify a protective order. Provide dates and times, who was involved, what was said or done, and whether anyone else saw or heard it. If any of it happened by text, voicemail, email, or social media, preserve the messages.

The court can act quickly once it hears about intimidation: issue a Criminal Protective Order, revoke or modify the defendant’s bail, or open a new investigation into the intimidation itself. For federal cases, the FBI accepts tips at tips.fbi.gov or through your local field office, and anonymous reporting is available.¹²
