A Practical Guide to California’s Litigation Privilege
Understand how California’s litigation privilege shields communications tied to lawsuits and why it matters in everyday legal practice.
California’s litigation privilege plays a central role in civil practice. It can transform what looks like a strong tort claim into a case that fails at the pleading stage, simply because the challenged conduct is deemed protected by statute and case law.
This guide explains what the litigation privilege is, how courts apply it, where its limits lie, and how it interacts with other doctrines like California’s anti-SLAPP statute. The goal is to give lawyers, litigants, and legal support professionals a working understanding they can apply in day-to-day practice.
1. Statutory Foundation: Civil Code Section 47(b)
California’s litigation privilege is codified at Civil Code § 47(b). The statute declares that certain categories of publications or broadcasts are privileged, including those made in:
- Legislative proceedings
- Judicial proceedings
- Other official proceedings authorized by law
- The initiation or course of other proceedings authorized by law
Although the statutory text is relatively concise, the California Supreme Court and Courts of Appeal have interpreted it broadly, turning it into an expansive immunity that applies far beyond statements made in open court.
1.1 What the statute is designed to protect
The litigation privilege shields qualifying communications from most civil liability. Courts have repeatedly emphasized that it functions as an absolute privilege for covered communications, not a mere evidentiary rule.
Key features include:
- Immunity from suit for damages based on the protected communication, not just exclusion of the communication from evidence
- Application to a wide range of torts, including defamation, interference, and many others, with limited exceptions such as malicious prosecution
- Coverage of prelitigation and ancillary communications that are logically tied to anticipated or ongoing proceedings
2. Core Policy Purposes Behind the Privilege
California courts consistently explain the breadth of the privilege by reference to its underlying policy goals. These purposes help courts interpret the statute in close cases.

| Policy Goal | Practical Effect |
|---|---|
| Ensure access to courts | Participants can litigate without fear of follow-on lawsuits based on what they say in the case. |
| Promote candid communication | Lawyers, parties, and witnesses can speak openly, increasing the chances that courts receive complete and accurate information. |
| Encourage finality | Judgments are less likely to be undermined by collateral tort litigation over statements made in the original case. |
| Avoid chilling advocacy | Attorneys can pursue claims and defenses vigorously, including tough negotiations and demand letters. |
2.1 Why the privilege is “absolute” in nature
In Silberg v. Anderson, the California Supreme Court described the privilege as absolute, meaning it applies regardless of malice, knowledge of falsity, or improper motive, as long as the other elements are satisfied. This can lead to harsh results for litigants harmed by abusive statements, but courts have concluded that the systemic benefits outweigh these concerns.
3. The Four-Part Test from Silberg v. Anderson
The modern formulation of California’s litigation privilege comes from the California Supreme Court’s decision in Silberg v. Anderson, 50 Cal.3d 205 (1990). The Court articulated a four-part test to determine when § 47(b) applies. A communication is privileged if it is:
- Made in a judicial or quasi-judicial proceeding
- By litigants or other participants authorized by law
- To achieve the objects of the litigation
- That has some connection or logical relation to the action
3.1 Judicial or quasi-judicial proceedings
The privilege clearly encompasses traditional court cases, but it also extends to quasi-judicial proceedings such as certain administrative hearings, arbitrations, and other forums with procedural safeguards resembling a court.
Examples that often qualify:
- Civil and criminal trials and appeals
- Administrative hearings before agencies exercising adjudicative functions
- Arbitrations and some forms of contractual dispute resolution
- Depositions and formal discovery proceedings connected to litigation
3.2 Participants authorized by law
The privilege covers a wide set of actors, including:
- Parties and their attorneys
- Witnesses and experts
- Judges and quasi-judicial officers
- Other individuals whose participation is required or permitted by law, such as interpreters or some consultants
The key inquiry is whether the person making the communication is participating in the proceeding in a legally authorized capacity.
3.3 To achieve the objects of the litigation
The requirement that the communication be made to achieve the objects of the litigation is interpreted broadly. Courts ask whether the statement was made to:
- Advance a claim or defense
- Gather evidence or information
- Negotiate settlement or procedural arrangements
- Otherwise further the resolution of the dispute
Even aggressive or poorly founded statements can satisfy this requirement if they are made in the course of pursuing or defending a claim.
3.4 Logical relation to the action
Finally, the communication must have a connection or logical relation to the case. Courts generally construe this requirement generously. Communications are not disqualified merely because they are tangential or involve harsh rhetoric, so long as they can reasonably be tied to issues in the proceeding.
4. Scope: Which Communications Are Protected?
Although the statutory language refers to a “publication or broadcast,” courts have applied the privilege to an extremely wide range of communications.
4.1 Examples commonly covered by the privilege
- Pleadings, motions, and briefs filed in court
- Oral statements made in hearings, conferences, and trial
- Deposition questions, answers, and related exchanges
- Communications between counsel regarding the case, including settlement negotiations
- Prelitigation demand letters sent in serious contemplation of filing suit
- Communications during mediation, arbitration, or administrative adjudication
4.2 Application beyond defamation
The doctrine originated in defamation law, but California courts have extended it to most tort claims arising from privileged communications, including claims for interference with contract, intentional infliction of emotional distress, and many forms of fraud or misrepresentation, among others. Malicious prosecution remains a notable exception and is governed by its own standards.
5. Important Case Law Shaping the Privilege
Several key decisions illustrate how California courts apply and expand the litigation privilege.
5.1 Silberg v. Anderson (California Supreme Court)
Silberg is the landmark decision establishing the modern four-part test and emphasizing the privilege’s absolute, policy-driven character. The Court stressed that the privilege should be interpreted broadly to protect access to the courts and prevent derivative lawsuits over communications made in litigation.
5.2 Rubin v. Green (California Supreme Court)
In Rubin v. Green, the California Supreme Court held that the privilege reaches initial communications leading up to the filing of a lawsuit, not only those made after a complaint is on file. This confirmed that attorneys and parties typically cannot be sued for torts based on communications that are logically tied to the decision to bring a case.
5.3 Breadth reaffirmed in later decisions
Subsequent cases have reiterated the privilege’s extraordinary reach. Courts have held that it can:
- Apply even where the conduct is alleged to be fraudulent, unethical, or illegal, if it is fundamentally communicative and tied to litigation
- Extend to some criminal contexts where the civil litigation privilege is implicated in related proceedings
- Cover communications in insurance and business disputes with a concrete link to anticipated or pending suits
6. Recognized Limits and Exceptions
Despite its breadth, California’s litigation privilege is not boundless. Understanding its limits is essential both for plaintiffs evaluating potential claims and for defendants asserting the privilege as a defense.
6.1 Malicious prosecution as a key exception
Malicious prosecution actions are expressly not barred by the litigation privilege. This cause of action serves as a narrow check on abuse of the judicial process, but its high elements (favorable termination, lack of probable cause, and malice) make it difficult to prove.
6.2 Statutory overrides of the privilege
Occasionally, the Legislature enacts statutes that implicitly or explicitly conflict with the litigation privilege. Courts generally preserve these statutes when:
- The statute is more specific than the litigation privilege; and
- Applying the privilege would render the statute largely inoperative
This analysis has led to limited, statute-specific exceptions in areas where the Legislature has clearly indicated a different policy choice.
6.3 Conduct that is not “communicative” in nature
The privilege is focused on acts that are communicative at their core. In some cases, courts distinguish between communicative acts (e.g., filing a pleading) and noncommunicative acts (e.g., wrongful seizure of property under a writ). Only the former are typically covered.
However, courts will look carefully at the essence of the conduct; many actions undertaken in litigation are closely tied to communications or are part of the communicative process, and thus fall within the privilege’s reach.
7. Relationship to California’s Anti-SLAPP Statute
California’s anti-SLAPP statute (Code of Civil Procedure § 425.16) provides a procedural mechanism to strike lawsuits arising from acts in furtherance of free speech or petition rights, including many litigation-related communications. The litigation privilege and anti-SLAPP law frequently intersect.
7.1 Substantive immunity vs. procedural screen
While they often point in the same direction, the two doctrines serve different functions:
- Litigation privilege: A substantive immunity that bars liability for covered communications under Civil Code § 47(b).
- Anti-SLAPP statute: A procedural tool allowing early dismissal of certain suits and potential fee shifting where protected activity is targeted.
A defendant may invoke both doctrines: the privilege as a substantive defense and anti-SLAPP as a way to dispose of the case quickly and seek attorneys’ fees.
7.2 Overlapping but not identical coverage
Not every communication protected by the litigation privilege necessarily qualifies as anti-SLAPP “protected activity,” and not every SLAPP claim is barred by the privilege. However, there is substantial overlap, especially where the conduct at issue involves statements in or in connection with judicial proceedings.
8. Practical Guidance for Legal Practitioners
For attorneys, paralegals, and legal support professionals in California, incorporating the litigation privilege into case analysis is critical at multiple stages.
8.1 Evaluating potential claims
Before filing a complaint based on harmful statements, counsel should:
- Identify whether the statements occurred in or closely around litigation or a quasi-judicial proceeding.
- Analyze whether the Silberg four-part test would likely be satisfied.
- Consider whether any recognized exceptions or overriding statutes might apply.
- Explain to clients that the privilege may bar even meritorious-feeling claims arising from litigation conduct.
8.2 Asserting the privilege as a defense
For defendants, the litigation privilege can be a powerful tool at the pleading stage. Common steps include:
- Raising the privilege in a demurrer, motion to strike, or motion for judgment on the pleadings.
- Pairing a privilege-based argument with an anti-SLAPP motion where appropriate.
- Framing the challenged conduct as fundamentally communicative and logically linked to litigation objectives.
8.3 Ethical and strategic considerations
Even though the privilege offers broad protection, it is not a license for unethical behavior. Professional responsibility rules, court sanctions, and reputational consequences continue to constrain what lawyers and parties can responsibly say in and around litigation.
Best practices include:
- Maintaining accuracy and integrity in pleadings and oral statements
- Avoiding gratuitous attacks or irrelevant accusations
- Documenting legitimate litigation purposes for sensitive communications
- Advising clients about both the existence and the limits of protection
9. Frequently Asked Questions (FAQs)
Q1: Does the litigation privilege protect knowingly false statements?
Yes, in many cases. The privilege is generally absolute if the Silberg elements are met. Courts have applied it even when statements are alleged to be false, malicious, or made with improper motives, because the focus is on the context and purpose of the communication, not its truthfulness.
Q2: Does the privilege apply before a lawsuit is filed?
Often, yes. Prelitigation communications, such as demand letters, may be protected if made in serious and good-faith contemplation of a lawsuit and sufficiently connected to potential litigation.
Q3: Can I still sue for defamation if I was harmed by statements made in court?
Typically no. Most defamation claims based on statements in judicial or quasi-judicial proceedings are barred by Civil Code § 47(b). Remedies may instead lie in sanctions, disciplinary complaints, or (in extreme cases) malicious prosecution, rather than a direct defamation suit.
Q4: Does the privilege apply to criminal cases?
It can. Although developed primarily in the civil context, California courts have recognized that the privilege may apply broadly to communications in any judicial proceeding, including some criminal matters, depending on the facts and the nature of the claim.
Q5: How is the litigation privilege different from attorney–client privilege or work product protection?
They serve different functions. Litigation privilege is a statutory immunity from liability for certain communications, while attorney–client privilege and work product doctrines govern confidentiality and discovery. A communication may be immune under § 47(b) even if it is not confidential, and vice versa.
