Malicious Prosecution

Malicious prosecution is a tort that holds a person liable for setting a criminal or civil proceeding in motion without probable cause and for a purpose other than justice, causing harm to the person accused. Malicious prosecution protects people from having the courts turned into a weapon, since the machinery of a case inflicts real cost long before any verdict. The malicious prosecution definition California courts apply is deliberately narrow, because the law does not want people with arguable claims frightened away from filing them. A malicious prosecution claim therefore succeeds only where the earlier case ended in the accused person’s favor, rested on no tenable grounds, and was driven by an improper motive.

What is Malicious Prosecution?

Malicious prosecution is a wrongful legal action brought without probable cause, pursued with malice, and terminated in favor of the person it targeted. Malicious prosecution requires all three of those conditions, so losing a case does not make the person who filed it liable. The three condition structure is what separates this tort from a simple disagreement about who should have won.

Cedars-Sinai Medical Center v. Superior Court (1988) 206 Cal.App.3d 414 described the tort as initiating or procuring the arrest and prosecution of another under lawful process, from malicious motives and without probable cause. Parrish v. Latham and Watkins (2017) 3 Cal.5th 767 confirmed that malicious prosecution is an intentional tort offering a remedy to someone subjected to a criminal charge or civil action maliciously instituted or maintained.

California courts treat the claim with open suspicion. Sheldon Appel Co. v. Albert and Oliker (1989) 47 Cal.3d 863 called malicious prosecution a disfavored cause of action, and explained that the elements have been carefully circumscribed so litigants with potentially valid claims are not deterred from bringing them by the threat of a later malicious prosecution suit.

Why is Malicious Prosecution considered a Tort?

Malicious prosecution is a tort because it compensates a private person for a private injury caused by another private party’s misuse of the courts. Malicious prosecution sits in California tort law rather than criminal law, which means the injured person files a lawsuit instead of waiting for a prosecutor to act. The remedy reflects that framing, since the recovery is money rather than punishment of the person who filed the earlier case.

Sagonowsky v. More (1998) 64 Cal.App.4th 122 described what the tort is meant to repair, namely out of pocket loss in attorney fees and costs, along with emotional distress and injury to reputation caused by groundless allegations sitting in public court records. The public record point matters, because a dismissed complaint stays searchable long after the case closes.

What are Examples of Malicious Prosecution?

Examples of malicious prosecution share one feature, which is a legal proceeding used as leverage rather than as a genuine attempt to resolve a dispute. Malicious prosecution examples appear in both criminal and civil settings, since California recognizes the tort in each. The six categories below cover the fact patterns California courts see most often.

1. False criminal reports giving police fabricated facts that lead to an arrest and formal charges.
2. Retaliatory lawsuits filed to punish someone for testifying, complaining, or suing first.
3. Untenable claims asserted with no legal basis to force a settlement or drive up costs.
4. Fabricated evidence presented to a grand jury or magistrate to obtain a charge or a warrant.
5. Groundless restraining order petitions used to gain advantage in a custody or property dispute.
6. Baseless liens and cross-complaints recorded or filed to pressure an opponent into concessions.

Untenable claims produced the leading California decision. Sheldon Appel arose from a law firm asserting a lien claim and recording a lis pendens, and the California Supreme Court used the case to fix the objective standard that now governs the probable cause element.

Can Filing False Criminal Charges be Considered Malicious Prosecution?

Yes, filing false criminal charges can be malicious prosecution, provided the charges produced a formal criminal proceeding. False criminal charges reported to police support the claim where the reporter knowingly supplied untrue facts indicating a crime. Sullivan v. County of Los Angeles (1974) 12 Cal.3d 710 held that actions against private persons require the defendant to have at least sought out police or prosecutors and falsely reported facts showing the plaintiff committed a crime.

An arrest alone is not enough. Van Audenhove v. Perry (2017) 11 Cal.App.5th 915 held that a malicious prosecution cause of action cannot rest on an arrest that never produced formal charges, at least where the arrest was made without a warrant.

Are Baseless Civil Lawsuits Considered Malicious Prosecution?

Yes, baseless civil lawsuits can support malicious prosecution, which California juries decide under CACI No. 1501 on wrongful use of civil proceedings. Baseless civil lawsuits reach the same three core requirements as criminal cases, so the earlier suit must have ended in the target’s favor, lacked probable cause, and been filed with malice. The civil version is the more common one in practice, since business disputes generate far more filings than private criminal referrals.

Losing the earlier case proves little. Jarrow Formulas, Inc. v. LaMarche (2003) 31 Cal.4th 728 held that obtaining summary judgment against a claim does not establish that the claim lacked probable cause or was filed with malice, because cases fail for many reasons connected to the evidence rather than to the merits of filing.

What are the Elements Required to Prove Malicious Prosecution?

The elements required to prove malicious prosecution are initiation of the earlier proceeding, favorable termination, lack of probable cause, malice, and resulting damages. CACI No. 1500 breaks the criminal version into six findings and CACI No. 1501 does the same for the civil version. The five elements below are what a California plaintiff has to establish.

1. Initiation of proceedings means the defendant was actively involved in commencing the earlier case, or in causing it to continue.
2. Favorable termination means the earlier case ended in the plaintiff’s favor in a way that reflected on the merits.
3. Lack of probable cause means no reasonable person in the defendant’s position would have believed there were grounds to proceed.
4. Malice means the defendant acted primarily for a purpose other than bringing the plaintiff to justice.
5. Damages means the plaintiff suffered actual harm, which the defendant’s conduct was a substantial factor in causing.

Every element has to hold, and favorable termination defeats more claims than people expect. Sagonowsky v. More (1998) 64 Cal.App.4th 122 held that a termination is not favorable just because the party prevailed, since it must relate to the merits by reflecting on the plaintiff’s innocence or lack of responsibility. Cote v. Henderson (1990) 218 Cal.App.3d 796 applied that rule to a nolo contendere plea, which negates favorable termination because its legal effect matches a guilty plea.

Judges and juries split the work. Probable cause and favorable termination are questions for the court, while the jury resolves any factual disputes the court needs answered first, and Sierra Club Foundation v. Graham (1999) 72 Cal.App.4th 1135 confirms that favorable termination is ultimately the court’s call.

How do Courts Determine Malice in a Prosecution Case?

Courts determine malice by asking whether the defendant acted primarily for a purpose other than bringing the plaintiff to justice or resolving a genuine dispute. Malice in a malicious prosecution case is a subjective question of fact for the jury, unlike probable cause. Greene v. Bank of America (2013) 216 Cal.App.4th 454 held that malice is not limited to actual hostility or ill will toward the plaintiff.

Inference does much of the work. Greene explained that a defendant who had no substantial grounds for believing in the plaintiff’s guilt yet instigated proceedings anyway invites the logical inference of an improper motive. Verdier v. Verdier (1957) 152 Cal.App.2d 348 set the limit on that reasoning, holding that malice may be inferred from want of probable cause but want of probable cause can never be inferred from malice.

Is Malicious Prosecution a Civil or Criminal Claim?

Malicious prosecution is a civil claim, even when the underlying proceeding was a criminal case. The civil character means the injured person files a complaint in superior court and carries the burden of proof on the ordinary civil standard rather than the criminal one. Malicious prosecution can arise from a criminal prosecution under CACI No. 1500, a civil action under CACI No. 1501, or an administrative proceeding under CACI No. 1502. The label describes what the defendant did in the earlier case, not the nature of the claim being brought now.

Is Malicious Prosecution a Crime?

No, malicious prosecution is not itself a crime in California, because it exists only as a civil cause of action. Conduct that produces a malicious prosecution claim can separately become a criminal offense under other statutes. Penal Code section 148.5 makes it a misdemeanor to report a criminal offense to a peace officer knowing the report is false, and Penal Code section 118 covers perjury. A prosecution under those statutes is brought by the district attorney and does not replace the injured person’s civil suit.

How is Probable Cause Evaluated in Malicious Prosecution Claims?

Probable cause is evaluated objectively, by asking whether the earlier claim was legally tenable on the facts known to the defendant at the time of filing. Probable cause means reasonable grounds to pursue a case, judged without regard to how the case later turned out. Sheldon Appel Co. v. Albert and Oliker (1989) 47 Cal.3d 863 held that a claim carries probable cause if any reasonable attorney would have thought it tenable, and that a claimant lacks probable cause only where any reasonable attorney would agree the claim was totally and completely without merit. The standard is a legal question for the trial court rather than a jury question.

Timing is the detail people miss. Courts assess the evidence available when the case was filed, so information that surfaced later cannot make an originally reasonable filing unreasonable. Greene v. Bank of America (2013) 216 Cal.App.4th 454 framed the criminal version of the question as whether it was objectively reasonable for the defendant to suspect the plaintiff had committed a crime.

Some findings in the earlier case carry forward. Williams v. Hartford Ins. Co. (1983) 147 Cal.App.3d 893 held that a grand jury indictment creates a prima facie case of probable cause the plaintiff must rebut, though proof that the indictment rested on false or fraudulent testimony can accomplish that rebuttal.

Is Actual Malice Required to Prove Malicious Prosecution?

No, malicious prosecution does not require the defamation standard, though it does require malice in its own distinct sense. Malicious prosecution malice means the defendant acted primarily for a purpose other than bringing the plaintiff to justice, which Greene confirms does not demand hostility or ill will. The defamation term actual malice means something different, namely knowledge of falsity or reckless indifference to whether a statement was true. Confusing the two standards is a common error, and it matters because the malicious prosecution version can be satisfied by an improper motive alone.

What is the Difference Between Negligence and Malice?

The difference between negligence and malice is that negligence falls short of the care a reasonable person would use while malice reflects an improper purpose or a conscious disregard of the risk. Negligence sets the lowest fault standard in California civil law, and malice sets one of the highest. Negligence in law asks what a reasonable person would have done, so an honest mistake can create liability. Malice asks why the defendant acted, which no amount of carelessness answers.

Malice demands more than carelessness. A lawyer who filed a weak case after sloppy research has been careless, and Sheldon Appel held that inadequate legal research cannot by itself establish a lack of probable cause. That distinction is why most malicious prosecution claims fail, since the plaintiff must show an improper purpose rather than a poor job.

How does Malicious Prosecution Apply in Civil Lawsuits?

Malicious prosecution applies in civil lawsuits whenever a party or an attorney files or continues a claim that no reasonable attorney would think tenable, for a purpose other than resolving the dispute. Malicious prosecution in civil cases is governed by CACI No. 1501, which mirrors the criminal instruction while replacing arrest with the filing of an action. The civil setting generates most California claims, since a business dispute can produce years of filings and fees.

Continued litigation counts as much as the original filing. A party who learns mid case that the claim has no basis and presses forward anyway may face the tort for maintaining the action, which is why the element speaks of causing the continuation of proceedings.

Defendants have a powerful early tool. Jarrow Formulas, Inc. v. LaMarche (2003) 31 Cal.4th 728 held that a malicious prosecution action is subject to the anti-SLAPP statute at Code of Civil Procedure section 425.16, because the claim arises from petitioning activity. A malicious prosecution plaintiff therefore has to substantiate the whole claim with evidence within weeks of filing, while discovery is stayed.

Can Someone be Sued for Filing a False Police Report?

Filing a false police report is generally privileged in California, and malicious prosecution is the narrow exception. False police reports fall under the absolute litigation privilege in Civil Code section 47(b), and Hagberg v. California Federal Bank (2004) 32 Cal.4th 350 applied that privilege to a bank’s report of suspected criminal activity, defeating claims for false imprisonment and related torts. The privilege does not bar a malicious prosecution claim, which is the one theory the courts have carved out.

Independent investigation cuts off most claims. Cox v. Griffin (2019) 34 Cal.App.5th 440 held that a person who merely alerts law enforcement to a possible crime is generally not liable where law enforcement independently investigates and decides on its own to prosecute.

Can you Sue for Wrongful Prosecution?

Yes, you can sue for wrongful prosecution through a malicious prosecution action, and sometimes through a federal civil rights claim as well. Wrongful prosecution as a phrase covers the same ground the tort addresses, so a California plaintiff pleads malicious prosecution rather than a claim by that name. The state claim requires favorable termination, absence of probable cause, and malice.

Federal law offers a parallel route. A claim under 42 U.S.C. section 1983 for unreasonable seizure pursuant to legal process tracks the tort elements, requiring that the criminal proceeding began without probable cause, served a purpose other than bringing the defendant to justice, and ended in the defendant’s favor.

Are Prosecutors Immune from Malicious Prosecution Claims?

Yes, prosecutors and other public employees are immune from malicious prosecution claims under Government Code section 821.6. Section 821.6 states that a public employee is not liable for injury caused by instituting or prosecuting a judicial or administrative proceeding within the scope of employment, even where the employee acted maliciously and without probable cause. CACI No. 1503 gives that immunity to the jury as an affirmative defense.

Leon v. County of Riverside (2023) 14 Cal.5th 910 fixed the boundaries of that immunity. The California Supreme Court held that section 821.6 applies only where the injury causing conduct was the institution or prosecution of an official proceeding. That holding rejected a line of appellate decisions reading the statute to cover any harmful act during an investigation. Leon narrows the immunity considerably for investigation conduct while leaving it firmly in place for the prosecution decision itself.

Can Private Individuals be Liable for Criminal Accusations?

Yes, private individuals can be liable for criminal accusations where they knowingly fed false facts to police or prosecutors. Private individuals face the claim without having personally signed the criminal complaint, and Zucchet v. Galardi (2014) 229 Cal.App.4th 1466 confirmed that a person may be civilly liable for malicious prosecution without signing the document that started the case. CACI No. 1504 explains what active involvement means for that purpose.

Continuing a prosecution counts too. A private person who takes an active part in procuring the continuation of criminal proceedings started by someone else faces the same liability as one who initiated them. Supplying false testimony at a later stage can therefore support the claim.

What Damages can be Recovered in Malicious Prosecution Cases?

Damages in malicious prosecution cases are built around the money spent defending the earlier case plus the personal harm the accusation caused. Courts calculate compensation by starting with documented out of pocket loss and then valuing the reputational and emotional injury the public filing produced. The five categories below follow Sagonowsky v. More (1998) 64 Cal.App.4th 122.

1. Attorney fees and costs incurred defending the earlier criminal or civil proceeding.
2. Lost earnings covering missed work, lost clients, and business the accusation cost the plaintiff.
3. Emotional distress damages for the anxiety, humiliation, and disruption the proceeding caused.
4. Reputational harm flowing from groundless allegations that remain in public court records.
5. Punitive damages where the plaintiff proves malice, oppression, or fraud by clear and convincing evidence.

Attorney fees behave unusually here. Fees from the earlier case are compensatory damages rather than a costs award, so a plaintiff proves them with invoices and testimony the same way any other economic loss is proven.

Is Emotional Distress Compensable in Malicious Prosecution Claims?

Yes, mental suffering is compensable in a malicious prosecution claim without any separate cause of action for it. Mental suffering damages sit inside the tort itself rather than beside it. Damages for emotional distress appear in Sagonowsky v. More (1998) 64 Cal.App.4th 122 alongside attorney fees and reputational injury, as harm the remedy exists to repair. The distress does not have to be severe in the way a standalone infliction claim requires.

Proof still matters. Testimony from the plaintiff, family members, and coworkers carries most of these claims, and treatment records for anxiety, insomnia, or depression strengthen the number a jury will accept.

Are Punitive Damages Available for Malicious Prosecution?

Yes, exemplary awards are available for malicious prosecution where the plaintiff proves malice, oppression, or fraud by clear and convincing evidence. Exemplary awards rest on Civil Code section 3294, and the improper purpose already at the center of the tort often supports that showing. A claim for punitive damages therefore travels with most malicious prosecution counts as routine pleading. Sheldon Appel itself came to the California Supreme Court on a verdict that included $82,000 in compensatory damages and $1 million in punitive damages.

One feature makes the exposure personal. Liability insurance generally cannot indemnify a malicious prosecution judgment in California, because Insurance Code section 533 bars coverage for a wilful act, which means a defendant may face punitive exposure out of pocket.

What Defenses are Available Against Malicious Prosecution Claims?

Defenses against malicious prosecution claims work by removing one of the five elements or by ending the case before discovery begins. Defenses are unusually strong here, since the tort is disfavored and the plaintiff has to prove every element. The six defenses below are the ones California defendants raise most often.

1. Probable cause defeats the claim where the earlier action was objectively tenable on the facts then known.
2. Absence of favorable termination defeats it where the earlier case ended on procedural grounds unrelated to the merits.
3. Reliance on counsel protects a party who disclosed the facts to a lawyer and acted on that advice, under CACI No. 1510.
4. Attorney reliance on client information protects a lawyer who reasonably relied on what the client reported, under CACI No. 1511.
5. Public employee immunity bars claims against prosecutors and other public employees under Government Code section 821.6.
6. Statute of limitations bars a claim filed more than two years after the earlier case terminated.

Probable cause is the defense that ends the most cases, and it does so early. A trial court decides the question as a matter of law, so a defendant with a colorable basis for the earlier filing can often resolve the claim on an anti-SLAPP motion rather than at trial.

How do you File a Malicious Prosecution Lawsuit?

Filing a malicious prosecution lawsuit starts after the earlier case has fully terminated in your favor, never while it is still pending. The sequencing is mandatory, since favorable termination is an element and no claim exists until the earlier proceeding ends. A plaintiff then files a complaint in the superior court for the county where the defendant resides or where the earlier case was brought.

Preparation matters more here than in most torts. An anti-SLAPP motion will likely follow the complaint within 60 days, discovery stays while it is pending, and the plaintiff must substantiate the entire claim with admissible evidence at that hearing. Claims against a public entity carry an additional step, since the Government Claims Act requires a written claim to be presented to the entity before any lawsuit is filed.

What Evidence is Required to Prove Malicious Prosecution?

Proving malicious prosecution requires the complete record of the earlier case plus evidence of what the defendant knew when the case began. The evidence is documentary first, because probable cause turns on facts known at filing and favorable termination turns on how the case ended. The six categories below support the individual elements.

1. Court records including the docket, the dismissal or acquittal order, and any statement of reasons.
2. The underlying pleadings showing what was alleged and how the allegations changed over time.
3. Communications including emails, demand letters, and recorded statements revealing the defendant’s purpose.
4. Witness testimony from investigators, prosecutors, or counsel about what the defendant reported.
5. Fee invoices documenting every dollar spent defending the earlier proceeding.
6. Medical and employment records supporting emotional distress and lost earnings.

Communications carry the most weight on the malice element. Malice is subjective, so a message revealing that the defendant wanted to punish rather than resolve often decides the case where the documents alone would look ambiguous.

How long does a Malicious Prosecution Case Take?

A malicious prosecution case in California usually takes one to three years, and the anti-SLAPP stage sets the pace. The timeline splits into two phases, since the special motion to strike is normally filed within 60 days of service and heard within about 30 days after that. An order granting or denying that motion is immediately appealable, and an appeal can add a year or more before the case returns to the trial court.

Cases that clear the motion move on ordinary tracks. Discovery, witness preparation, and trial setting then follow the same schedule as other intentional tort cases, which in most California counties means a trial date 12 to 24 months out.

What does a Malicious Prosecution Lawyer do?

A malicious prosecution lawyer evaluates whether all five elements exist, assembles the earlier case record, and carries the claim through the anti-SLAPP stage. The evaluation comes first because most claims fail at probable cause or favorable termination, and a candid answer early saves a client years. A lawyer then obtains the complete file from the earlier proceeding, reconstructs what the defendant knew at filing, and documents every dollar of defense cost.

Strategy shapes the outcome more than in ordinary tort work. Counsel decides whether to plead abuse of process under CACI No. 1520 alongside the malicious prosecution count, whether to name the opposing lawyer as well as the client, and how to preserve the record for the appeal that frequently follows an anti-SLAPP ruling.

Can a Personal Injury Attorney Handle Malicious Prosecution Cases?

Yes, some personal injury attorneys handle malicious prosecution cases, because the damages and the two year deadline match ordinary tort practice. Emotional distress, lost earnings, and reputational harm are injuries a personal injury practice values routinely. A personal injury attorney with real litigation experience in this area can also assess the probable cause question a judge will decide, the anti-SLAPP exposure, and whether Escamilla v. Vannucci (2025) 17 Cal.5th 571 keeps a claim against opposing counsel alive. Those questions sit outside the ordinary collision and premises caseload, so asking a firm how many malicious prosecution matters it has litigated is worthwhile. A free case review is the usual starting point for a California malicious prosecution claim.
