California anti-SLAPP motions — defending against weaponized litigation.

What anti-SLAPP is and how CCP §425.16 works#

California's anti-SLAPP statute (Code of Civil Procedure §425.16) was enacted in 1992 to address Strategic Lawsuits Against Public Participation — lawsuits filed primarily to silence or intimidate defendants who exercised constitutionally protected rights, particularly free-speech and petition rights. The statute provides defendants a special motion to strike that, if granted, dismisses the claim early in litigation with fee-shifting in favor of the prevailing defendant.

The procedural mechanics are unusual within California civil litigation. An anti-SLAPP motion can be filed within 60 days of service of the complaint. Discovery is automatically stayed once the motion is filed (CCP §425.16(g)). The court must rule on the motion before the case proceeds. An order denying the motion is immediately appealable (CCP §425.16(i)); an order granting it produces immediate dismissal of the affected claims. The fee-shifting under §425.16(c) is mandatory in favor of the prevailing defendant — though discretionary in favor of plaintiff against a frivolous motion.

The combined effect: anti-SLAPP can resolve a case within months, with fees recovered. For defendants facing weaponized litigation grounded in protected activity, the statute is one of the most powerful tools in California civil procedure. For plaintiffs whose claims even arguably touch protected activity, anti-SLAPP exposure shapes the entire litigation strategy from the outset.

The two-step test#

Anti-SLAPP analysis follows a sequential two-step framework. The defendant carries the burden at step one; if step one is satisfied, the burden shifts to the plaintiff at step two.

Step one: protected activity#

The defendant must demonstrate that the plaintiff's claim arises from conduct within one of the four categories of protected activity defined by §425.16(e):

(e)(1): statements in legislative, executive, or judicial proceedings. Anything said in a court filing, a deposition, a legislative hearing, an administrative proceeding, or similar official proceeding.

(e)(2): statements in connection with issues under consideration in such proceedings. Statements outside the official proceeding but related to ongoing or anticipated proceedings — communications with witnesses, settlement negotiations, statements to government agencies about regulated conduct.

(e)(3): statements made in a public forum in connection with an issue of public interest. Internet posts, newspaper letters, public speeches, statements at public meetings on matters of public concern. The 'public interest' framing has been litigated extensively; the bar is meaningful but not impossibly high.

(e)(4): other conduct in furtherance of constitutional rights of petition or free speech in connection with a public issue. The catch-all category. Conduct that doesn't fit (e)(1)–(e)(3) but otherwise furthers protected constitutional rights on matters of public concern.

Step two: probability of prevailing#

If the defendant establishes protected activity at step one, the burden shifts to the plaintiff to demonstrate a probability of prevailing on the claim. This is a minimal merits showing — not a definitive merits adjudication. The plaintiff must show the claim has 'minimal merit' supported by competent evidence; California courts describe this as the plaintiff demonstrating the claim is 'legally sufficient and supported by a sufficient prima facie showing of facts to sustain a favorable judgment if the evidence submitted by the plaintiff is credited.'

The probability-of-prevailing analysis at step two is fact-intensive and evidence-based. The plaintiff submits declarations, documents, and other evidence; the defendant responds with contrary evidence and legal arguments. The court evaluates the evidence — but does not weigh credibility or resolve disputed facts; if the plaintiff's evidence taken at face value supports the claim, step two is satisfied and the motion is denied.

Step one analysis — what counts as protected activity#

The most heavily litigated aspect of California anti-SLAPP practice is step one. Defendants overreach by labeling ordinary commercial conduct as 'protected activity'; plaintiffs underestimate the breadth of the protected categories. The reality sits between the extremes — and varies materially by category and by underlying conduct.

Statements in judicial proceedings (e)(1). Broadly protected. Anything said or written in a court filing, in deposition, at hearing, or in formal litigation procedure. Common cases: defamation claims based on allegations in pleadings; tortious interference claims based on legal threats made in litigation; emotional distress claims based on aggressive litigation conduct. Plaintiffs frequently underestimate how much of typical 'aggressive litigation conduct' falls under (e)(1) protection.

Pre-litigation communications (e)(2). The doctrine has expanded over time. Pre-suit demand letters, communications with government agencies about regulated conduct, complaints to professional licensing boards, internal investigations conducted under threat of litigation — all have been recognized as falling within (e)(2) protection in appropriate cases. The 'in connection with' threshold requires meaningful relationship to actual or contemplated proceedings; communications too remote from litigation don't qualify.

Public-forum statements (e)(3). The public-interest requirement is the key filter. Internet review sites (Yelp, Glassdoor, Google reviews) about businesses generally satisfy public interest when the underlying matter affects more than just the parties. Statements about purely private business disputes — even when published online — may not qualify because the dispute lacks broader public concern.

Catch-all conduct (e)(4). The narrowest in practice. Courts require both furtherance of constitutional rights and connection to a public issue. Commercial conduct conducted by businesses for business purposes generally falls outside (e)(4) even when it involves expressive elements. The category captures meaningful First Amendment activity in non-traditional fora; it doesn't extend to all expressive activity by businesses.

Step two analysis — proving the case has 'minimal merit'#

Once step one is established, the plaintiff's burden at step two is meaningful but not insurmountable. The minimal-merit standard requires legally cognizable claims supported by competent evidence — not full proof, but enough that a reasonable trier of fact could rule for the plaintiff on the evidence presented.

Plaintiffs commonly fail step two for one of three reasons. First: legal insufficiency. The claim, as pleaded, doesn't state a cause of action under California law. Defamation claims based on opinion or non-actionable hyperbole; tortious interference claims that don't satisfy California's wrongful-means requirement; emotional-distress claims that don't meet the outrageous-conduct standard. Each fails at step two as a matter of law without reaching the evidence.

Second: privilege defense. California's litigation privilege under Cal Civ. Code §47(b) bars defamation, tortious-interference, and similar tort claims based on statements made in judicial proceedings. The litigation privilege applies broadly and is difficult to overcome; many claims that arise from pre-litigation communications are barred at step two by §47(b).

Third: evidentiary gaps. The plaintiff's declarations and documents don't actually support the claim's elements. Conclusory statements without underlying facts; hearsay without exception; speculation about defendant's motivations without admissible evidence. The minimal-merit standard requires prima facie evidence, not just allegations.

Fee-shifting and recovery#

The fee-shifting provision in §425.16(c) is one of the most consequential aspects of anti-SLAPP practice. A defendant who prevails on an anti-SLAPP motion is entitled to attorney's fees and costs as a matter of right. The award is mandatory; the court has discretion only on the amount (which must be reasonable). Fees include the cost of preparing the motion, opposing the plaintiff's evidence, attending hearing, and (if applicable) appellate proceedings.

Fee recovery on a granted anti-SLAPP motion routinely runs $15,000–$50,000 for straightforward motions and $75,000–$200,000+ for complex or appealed motions. The fee award creates the structural reason anti-SLAPP works — even when the underlying claim seeks only modest damages, the fee-shifting potential turns the motion into a meaningful financial event.

Fees can also shift against the defendant. If the court finds the anti-SLAPP motion was 'frivolous or solely intended to cause unnecessary delay,' §425.16(c)(1) authorizes fees to plaintiff. The frivolous-motion fee award is discretionary and meaningfully harder to obtain than the prevailing-defendant award, but it does create downside exposure for defendants who file anti-SLAPP motions on tenuous step-one theories.

Timing and procedure#

Filing window. §425.16(f) requires the motion to be filed within 60 days of service of the complaint, though the court has discretion to permit later filing. The 60-day window is short and unforgiving — anti-SLAPP analysis has to begin immediately upon service. Defendants who delay assessing anti-SLAPP potential frequently lose the timing window.

Discovery stay. Once the motion is filed, discovery is automatically stayed under §425.16(g). The plaintiff cannot conduct discovery on the claims subject to the motion while the motion is pending. The court can permit limited 'specified discovery' on the issues raised by the motion (typically witness depositions on factual issues going to step two), but full merits discovery doesn't proceed until the motion is resolved.

Briefing and hearing. The motion is briefed under California's standard motion schedule (16 court days notice, opposition 9 court days before hearing, reply 5 court days before). The hearing is in court; the judge rules on submissions and oral argument.

Order and appeal. An order denying anti-SLAPP is immediately appealable as of right under §425.16(i); the appellate process typically adds 12–24 months to case timeline. An order granting anti-SLAPP dismisses the affected claims (or the entire case if all claims fall to the motion). Plaintiff can also appeal a grant, with similar appellate timing.

Common defendants and protected-activity categories#

Anti-SLAPP motions appear most frequently in specific recurring categories:

Defamation defendants. Online reviews, professional reputation claims, statements at public meetings. The (e)(3) and (e)(4) public-interest framework typically applies. Strong cases when the underlying statement is opinion, hyperbole, or substantially true.

Litigation conduct defendants. Defendants facing tortious-interference, intentional-infliction, or business-tort claims based on conduct that occurred in or near other litigation. The (e)(1) and (e)(2) framework plus the §47(b) litigation privilege combine to provide strong defense.

Government-petition defendants. Whistleblowers, agency complainants, witnesses at regulatory proceedings. Conduct in furtherance of protected petition rights typically falls within (e)(2) and is independently protected against retaliation under specific statutory frameworks.

Public-interest commentators. Journalists, activists, public-interest organizations, and commenters on matters of public concern. (e)(3) and (e)(4) typically apply when underlying matter has demonstrable public significance.

Business defendants in commercial disputes. The least promising category. Most commercial disputes don't involve protected activity at step one; defendants who file anti-SLAPP motions in routine commercial cases routinely lose at step one and face fee exposure for frivolous motions. Anti-SLAPP isn't a generalized defendant's tool — it's a tool specifically for cases involving protected activity.

Tactical considerations#

The decision to file anti-SLAPP requires careful merits assessment, not just availability assessment. Several questions shape the decision:

How strong is step one? A weak step-one argument loses the motion and risks fee-shifting against the defendant. The clearest step-one situations are well-established protected activity (statements in court filings, online reviews of businesses, public-interest commentary). Borderline step-one situations need careful evaluation of the recent case law in the specific category.

How strong is step two — from the defendant's perspective? Even with clear protected activity, the plaintiff may have a meritorious claim. Anti-SLAPP doesn't win on procedural grounds alone; the motion succeeds only if the claim also lacks substantive merit. Cases where the plaintiff has clear evidence and a sound legal theory don't yield to anti-SLAPP regardless of step-one analysis.

What's the timeline tradeoff? A granted anti-SLAPP motion ends the case quickly with fee recovery — usually the best possible defense outcome. A denied motion can be appealed, which freezes the case for 12–24 months and may produce settlement leverage that wouldn't otherwise exist. But the denial also signals the underlying claim has at least minimal merit, which weakens settlement positions on the substance.

What's the fee exposure tradeoff? A successful motion produces fee recovery. A frivolous motion produces fee exposure. Most denied motions don't trigger frivolous-motion fees (the bar is meaningful) — but the risk exists and rises proportionally with how unreasonable the step-one position was.

Why same-firm representation matters here#

Anti-SLAPP is high-stakes specialized motion practice. The success rate depends on substantive litigation experience, knowledge of the recent case law in the specific protected-activity category, and disciplined merits analysis at both steps. Generic commercial litigation experience isn't enough — anti-SLAPP requires specific knowledge of California's protected-activity framework and the procedural pace the statute imposes.

Same firm advises on protected activity before litigation. Same firm files anti-SLAPP if litigation arrives. That continuity matters because anti-SLAPP analysis often turns on facts the litigation firm wouldn't have if it didn't already know the matter. A defendant whose underlying conduct may attract litigation benefits enormously from counsel who has framed the conduct contemporaneously with anti-SLAPP exposure in mind — preserving evidence, documenting public-interest framing, ensuring the conduct itself was structured to maximize step-one protection. Anti-SLAPP-ready counsel is structurally different from generic litigation counsel.
